“Sisters Are Doin’ It for Themselves”: Gender Differences in Singles’ Well-Being

The experience of singles has been largely overlooked in relationship science, garnering a need for understanding correlates of singles’ well-being. Gender is an important focus of well-being research, and qualitative work on singlehood has suggested that men and women may have experiences of singlehood that differ in important ways. In this study ( N = 5941; 50% men; Mage = 31.74), we provide the first comprehensive, descriptive profile of gender differences on a suite of variables with important ties to well-being in singlehood; satisfaction with relationship status, life satisfaction, sexual satisfaction, and desire for a partner. Our results suggest that single women, on average, report higher levels of satisfaction with relationship status, life satisfaction, sexual satisfaction, and lower desire for a partner. Exploratory analyses showed significant gender interactions with age and ethnicity. Overall, these findings suggest that women are, on average, happier in singlehood than men.

Primary care experiences of adults reporting learning disability: a probability sample survey.

Background Adults with learning disability face multiple adversities, but evidence on their needs and primary care experiences is limited. Aim To compare the characteristics and primary care experiences of adults reporting learning disability with those who did not. Design and setting An analysis of the 2022 General Practice Patient Survey, a national probability sample survey conducted in 2022 with people registered with NHS primary care in England. Method This analysis reports descriptive profiles, weighted and with 95% confidence intervals. Logistic regression models adjusting for gender, age, ethnicity, and area-level deprivation compared experiences of adults reporting learning disability with those who did not. Results Survey participants comprised 623,157 people aged 16 or older, including 6,711 reporting learning disability. Adults reporting learning disability were more likely to be male, younger, of mixed or multiple ethnicities, and live in more deprived areas. All chronic conditions included in the survey were more common in adults reporting learning disability, especially reported sensory, neurodevelopmental, neurological, and mental health conditions. Adults reporting learning disability were twice as likely to have a preferred GP, and less likely to find their practice's website easy to navigate. They were also less likely to have confidence and trust in their healthcare professional, or feel their needs were met. Conclusion Adults reporting a learning disability had a higher likelihood of chronic health conditions. Their reported experiences of primary care indicate that despite recent initiatives to improve services offered, further adaptations to the consistency and ease of access to primary care is needed.

Bioinformatic Analysis from a Descriptive Profile of miRNAs in Chronic Migraine.

Chronic migraines have been described chiefly only from a clinical perspective. However, searching for reliable molecular markers has allowed for the discovery of the expression of different genes mainly associated with inflammation, neuro-vascularization, and pain-related pathways. The interest in microRNAs (miRs) that can regulate the expression of these genes has gained significant relevance since multiple miRs could play a key role in regulating these events. In this study, miRs were searched in samples from patients with chronic migraine, and the inclusion criteria were carefully reviewed. Different bioinformatic tools, such as miRbase, targetscan, miRPath, tissue atlas, and miR2Disease, were used to analyze the samples. Our findings revealed that some of the miRs were expressed more (miR-197, miR-101, miR-92a, miR-375, and miR-146b) and less (miR-133a/b, miR-134, miR-195, and miR-340) than others. We concluded that, during chronic migraine, common pathways, such as inflammation, vascularization, neurodevelopment, nociceptive pain, and pharmacological resistance, were associated with this disease.

Characterization and Profiling of Key Odorants in Roasted Hybrid American-European Hazelnuts.

American-European hybrid hazelnuts (Corylus americana × Corylus avellana) are an emerging crop in the Upper Midwest of the United States that have been reported to have unique sensory characteristics compared to traditionally grown European hazelnuts. In this study, key odor-active compounds in a roasted hybrid hazelnut variety (C. americana × C. avellana) were identified and profiled across different hybrid hazelnut varietals to understand sensory differences. Gas chromatography/mass spectrometry/olfactometry analysis identified 33 odorants with high flavor dilution factors (FD ≥ 16) in the roasted hybrid hazelnut, including 2-acetylpyrazine and 2-aminoacetophenone as first reported hazelnut odorants. Descriptive sensory analysis profiles of the roasted hazelnut and an aroma recombination model consisting of 27 odorants quantified above their odor detection thresholds were not significantly different for the six evaluated attributes, confirming the aroma contribution of the identified odorants. Variation in all 33 aroma-active compounds across 12 hybrid and two European hazelnut varieties was visualized through principal component analysis and related to aroma profiles previously characterized by consumers.

Sensory studies on the taste and flavor perception of food products by anodal transcutaneous electrical stimulation.

Electrical taste technologies designed to modify the taste of foods have recently garnered increasing recognition as a viable strategy to regulate excessive salt intake. Transcutaneous electrical stimulation (TES) is a method used in non-invasive electrical taste stimulation, which involves the placement of electrodes near the mouth (not inside the mouth) to avoid disruption of natural eating behavior. Previous studies have demonstrated the taste-enhancing effect of anodal TES (aTES) applied to the anterior part of the jaw. However, there has been no detailed examination of TES-mediated alteration of the taste characteristics of different types of food products with complex flavors. In this study involving 27 human participants, we used the Quantitative Descriptive Profile method to conduct a sensory evaluation investigation of aTES-mediated changes in taste characteristics of six processed food products: cold potato potage, chicken broth soup, rice porridge with pickled plums (umeboshi), Chinese pork stir fry, stir-fried pork and radish, and fried dumplings. The application of aTES significantly increased both the intensity of saltiness and overall taste in all six foods. Furthermore, aTES significantly enhanced and suppressed some of the flavor attributes of these foods. An aTES-mediated increase in palatability was only observed in fried dumplings, indicating that further investigation of the relationship between flavor characteristics and palatability is needed.

Advanced methods for target audience identification: enhancing marketing strategies through machine learning and data analytics

Purpose: This article presents a novel approach that leverages advanced data analytics and machine learning techniques to enhance marketing strategies. By precisely targeting and segmenting audience groups based on their descriptive profiles, the study aims to significantly improve the efficacy of marketing campaigns. Methods: The study employs several clustering and community detection algorithms, including Louvain Community, Greedy Modularity, and Label Propagation. These methods are applied to diverse datasets to identify distinct groups within the audience that exhibit specific behavioral and preference patterns. The approach emphasizes data-driven decision-making, which involves making decisions based on the analysis of data rather than intuition or observation, to optimize marketing outcomes. Results demonstrate that employing advanced clustering techniques can significantly refine the segmentation process, leading to more targeted marketing efforts. These methods successfully identified nuanced sub-groups within the datasets, which corresponded closely with customer behaviors and preferences variations, thereby allowing for more tailored marketing strategies. Discussion: The study's findings underscore the imperative for marketers to embrace sophisticated analytical techniques. Machine learning has the potential to transform marketing strategies by providing deeper insights into customer segmentation. This research highlights the importance of staying ahead of the curve in the face of the complexities of consumer markets and evolving business environments.

Exploring Corbières red wine typicity: evaluation of the impact of winemaking processes on the chemical composition and organoleptic properties of wines from different terroirs

Aromatic and polyphenolic compounds play an important role in the quality of red wines, contributing not only to flavour, but also to colour, astringency and bitterness. To explore the influence of climate and oenological practices on the chemical and sensory profile of wines, red blends from five terroirs of the Corbières appellation were analysed, taking into account two production years (2018 and 2019). The wines were a blend of at least two of four main grape varieties: Syrah, Grenache, Carignan and Mourvèdre. Volatile compounds were evaluated by HS-SPME-GC-MS, while wine pigments and derived pigments were evaluated by spectrophotometric measurements. In addition, the wines were compared using a quantitative descriptive analysis sensory profile method. The percentage of the blend significantly influenced the polyphenolic and aromatic characteristics of the wines, showing distinct 'typicity' characteristics between sub-regions. Maceration techniques, on the other hand, did not did not allow us to discriminate between sub-regions, but enabled a better understanding of chemical and sensory differences between samples.

Living a private lie: intersectional stigma, depression and suicidal thoughts for selected young key populations living with HIV in Zambia

BackgroundLimited research has been conducted on the forms, manifestations and effects of intersectional stigma among young HIV-positive men who have sex with men (MSM) and transgender women (TGW) in Zambia. In this study, we aimed to address this gap by elucidating the experiences of these in a small group of young, HIV + MSM and TGW in Zambia.MethodsWe applied a mixed-methods design. Data were collected from January 2022 to May 2022. Qualitative data were collected using in-depth interviews while quantitative data were collected using a questionnaire. Qualitative transcripts were coded using thematic analysis while paper-based questionnaire data were entered into Kobo Connect. Descriptive statistics, using chi-squared tests were calculated using Excel. In this paper, we provide a descriptive profile of the sample and then focus on the qualitative findings on intersectional stigma, depression, and contemplation of suicide.ResultsWe recruited 56 participants from three sites: Lusaka, Chipata, and Solwezi districts. Participants’ mean age was 23 years. The study found that 36% of all participants had moderate to significant symptoms of depression, 7% had major depression, 30% had moderate signs of anxiety, 11% had high signs of anxiety, 4% had very high signs of anxiety and 36% had contemplated suicide at least once. A greater proportion of TGW had moderate to significant symptoms of depression (40%) or major depression (10%) compared to MSM, at 33% and 6%, respectively (X2 = 0.65; p = 0.42). Similarly, more TGW (55%) had contemplated suicide than MSM peers (36%, X2=1.87; p = 0.17). In the qualitative data, four emergent themes about the forms, manifestations, and effects of intersectional stigma were (1) HIV, sexual orientation, and gender identity disclosure; (2) Dual identity; (3) Challenges of finding and maintaining sexual partners; (4) Coping and resilience. Overall, having to hide both one’s sexuality and HIV status had a compounding effect and was described as living “a private lie.”ConclusionEffectively addressing stigmas and poor mental health outcomes among young HIV-positive MSM and TGW will require adopting a socio-ecological approach that focuses on structural interventions, more trauma-informed and identity-supportive care for young people with HIV, as well as strengthening of authentic community-informed public health efforts.

Development of Sourdough Bread Made with Probiotic Lactiplantibacillus plantarum Bacteria Addition

Bread is a staple in the diet of people around the world. A new solution is the addition of selected strains of bacteria to the sourdough to increase the quality of the obtained bread. In the presented research, seven bread samples were baked and analysed, which differed by the selected strain of bacteria of the Lactiplantibacillus plantarum species used in sourdough preparation. The bread was subjected to a 3-day ageing test. The structure of the products was analysed using the texture profile analysis (TPA) method on days 1 and 3 of storage. It was observed that the samples with the addition of selected L. plantarum bacterial strains underwent the process of staling much slower than the control sample. The analysis of the viability of lactic acid bacteria (LAB) in products after 1 and 3 days of storage was also performed. The obtained results indicate the highest survival rate of LAB in the control sample, i.e., the native microflora of baker’s starters, which was at 3.07 log CFU after one-day storage after baking. In the case of other samples, the viability of the bacteria was below 2.74 log CFU, which confirms a certain degree of thermostability of selected bacterial strains. The belonging of the isolated bacteria to the species L. plantarum was proven via genetic identification using the PCR method. A sensory analysis using the quantitative descriptive profile (QDP) method was also performed on the bread immediately after it was baked and cooled down. The analysis showed that the use of L. plantarum strains as starters did not significantly affect the aromatic and taste profiles of the samples compared to the control sample. The overall quality of the bread samples was high, above 6 units, with the control sample having the highest sensory quality of 7.5 units (on a scale of 0–10 units). The presented research suggests that it is possible to produce bread with bacteria that have health-promoting properties and good sensory quality, which enhances the textural features of the final product. Future research will focus on attempting to microencapsulate selected thermostable probiotic bacteria.

Consumer preferences of artificial and natural flavours: a case in soft ice cream

Consumers have a high awareness regarding the additives used in their food products. The use of artificial and natural flavours as additives in a food product is debatable and it will directly impact sensory attributes and consumer preferences. The objective of this study was to investigate the different sensory profiles and consumer acceptability of soft ice cream with different types of vanilla flavours (artificial vs. natural). In addition, liking segmentations based on gender and age group were also investigated. Descriptive sensory profiles (n=10), differentiation testing (n=40), and consumer acceptability test (n=162) were determined. There were no significant differences for sensory attributes except for texture (p= 0.001). The differentiation testing disclosed no differences between artificial and natural vanilla flavours (p=0.09). However, soft ice cream made with the artificial vanilla flavour has a significantly higher liking (p< 0.01) compared to the natural flavour. There were no significant differences in consumer acceptability levels based on gender and age-group segmentations. This study can be used as a primary reference to select appropriate flavours of artificial and natural in a certain food product.

Incidents et accidents médicamenteux en établissement de santé : une analyse descriptive au sein d’un CHU mère-enfant de 2018 à 2022

The safety of care provided is based on an analysis of medication incidents and accidents. The primary objective was to describe medication-related incidents and accidents (I&A) within a university-affiliated hospital. This retrospective descriptive study was based on data from a 500-bed mother-child university-affiliated hospital. All I&As declared between April 1, 2018, and March 31, 2022, were considered. The analysis included all medication-related I&As that occurred during an admission or in an outpatient setting. Some variables were recoded manually. Descriptive statistical analyses were performed. A total of 23 284 I&As were considered, including 7578 medication-related I&As. Daily averages of 15.9 ± 14.0 I&As and 5.2 ± 0.3 medication-related I&As were reported. There were 22.4 medication-related I&As/1000 inpatient days. The majority of medication-related I&As occurred in surgery (20%, 1530/7578), oncology (19%, 1405/7578), and pediatrics (16%, 1200/7578). Most were associated with incorrect dosing (21%, 1575/7578); infiltration, extravasation, or removed lines (19%, 1405/7578); and omissions (16%, 1205/7578). Physical consequences were reported in 15% (1158/7578) of the medication-related I&As. Conversely, psychological consequences were reported in less than 1% (44/7578) of medication-related I&As. This study provides a comprehensive descriptive profile over a 4-year period. Most of the reported I&As did not lead to consequences for patients. The sharing of ratios promotes comparative analysis with other facilities and can contribute to discussions about risk reduction. A culture of reporting events is present within this health care facility.

A profile of two different applicant test batteries with regards to sex and age in successful law enforcement applicants.

Law enforcement (LE) applicant assessments and initial academy training vary greatly across the United States of America (USA), with 820+ academies operating across 50 different states. Rising obesity and declining physical fitness underscore the need for benchmarks of applicant physical performance. Create a "point-in-time" descriptive profile of the performance of LE applicants and determine any differences between males, females, and age using two applicant test batteries (ATBs). Archival data from one large USA LE academy were analysed. Applicants completed one of two ATBs; ATB1 (n = 1674): 68.8-meter agility run (AR), 60-s push-ups, 60-s sit-ups, 60-s arm ergometer revolutions, and 2.4 km run; ATB2 (n = 355): AR, 60-s push-ups, 60-s sit-ups, and a multistage fitness test. Data were coded for sex and age. Independent samples t-tests compared the sexes. A one-way ANOVA with Bonferroni post hoc analysis compared age groups (18- 24, 25- 29, 30- 34, 35- 39, 40 + years). Males outperformed females in all fitness assessments across both ATBs (p≤0.02). The 18- 24 age group demonstrated faster run times in the AR and 2.4 km for ATB1 compared to all groups. (p≤0.03). In ATB2, the 18- 24 age group was faster in the AR compared to all other groups except the 25- 29 age group (p≤0.026). Regardless of ATB used, females and older applicants generally would benefit from specific fitness training to better prepare for academy. Older applicants may experience greater challenges in running tasks, especially those involving sprinting, which could also be impacted by qualities important for running/sprinting (i.e., maximal strength and power).

Evaluation of FOXP3 and IL10 as immunosuppressant markers in pediatric acute lymphocytic leukemia patients in Iraq

Background. Increased FOXP3+ Treg levels in the TME were positively correlated with a worse prognosis in certain cancer patients. FOXP3 was significantly overexpressed in pediatric B-ALL patients, and this overexpression was associated with a worse prognosis and increased risk of disease relapse. It is unknown if children that have the condition would have different prenatal immune development. This study investigates the relationship between IL10, and immunological development in pediatric ALL. Methods. The 70 blood samples from children between the ages of 2 and 14 for both sexes were obtained from patients with Acute lymphoblastic leukemia. Furthermore, this study comprised 54 healthy controls. Included in this study, FOXP3 expression on leukemic blast cells were assessed using flow cytometry. And IL10 were assessed using ELISA test. Results. Increase of FOXP3 cells was noticed in children with ALL compared to healthy individuals with significant increase of FOXP3 (mean ± SD, 91.156 ± 12.255 vs. 14.88 ± 7.897pg/ml (p &lt;0.05). In light of these findings, significant differences in the levels of FOXP3, which was higher in induction than consolidation stage of chemotherapy (mean ± SD, 91.24± 11.078vs. 86.35±5. 16.66) pg/ml (p &lt;0.05). Additionally, it was found that the prevalence of lymphoblast that express FOXP3 was notably higher in the HR group in contrast to the SR group (mean ± SD, 95.52± 5.79 vs. 42.88± 31.38) pg/ml (p &lt;0.05). Following these findings, significant differences in the levels of FOXP3 was higher in relapse than new diagnosis chemotherapy stage (mean ± SD, 95.66± 5.167 vs. 91.035±5. 13.177) pg/ml (p&lt;0.05). On the other hand, children with ALL were also found to have significantly higher levels of IL10 in the current study when compared to healthy controls (mean ± SD, 0.146 ± 0.145 vs. 0.076 ± 0.10 pg/ml (P &lt;0.05). Following these findings, significant differences in the levels of IL10 was higher in consolidation than induction chemotherapy stage (mean ± SD, 0.165± 0.084 vs.0 .0720±.018) pg/ml (p &lt;0.05), the serum levels of IL-10 were evaluated in the two groups: new diagnosis and relapse cases. As in the description profile, serum levels are higher in the relapse group with a highly significant difference. For the parameter IL10 (P ≤0.05). As for he mean level, it was as follows: of IL10 (0.130) pg/ml and (0.216) pg/ml, with (P-value =0.0001) in new diagnosis and relapse receptivity. Conclusions. According to our findings, B-ALL patients have significant amounts of both FOXP3 and IL10. This pilot study provides a novel way to look into the process mediating the appearance of these markers in a greater number of B-ALL patients at various stages of their treatment.

Sensory and volatile aromatic compound differences of paired lamb loins with 0 or 14 day dry aging

Flavor of lamb is a major driving factor in eating satisfaction. Dry aging has been used in beef to alter flavor and tenderness. The objective of the research was to determine what affect dry aging had on flavor attributes and the volatile compounds that influence the perception of flavor. Lambs (n = 10) were fed an alfalfa-based concentrate diet for 60 d prior to harvest. Loins were obtained from both sides of the carcass and randomly assigned to an aging treatment; no age (boned and frozen day 0) or 14 d of dry age in cold storage (4°C, 55%RH). Descriptive flavor profile panel evaluated samples and volatile compounds were analyzed from cooked samples. No differences were detected by descriptive flavor panel between fresh and dry aged loin chops for most flavor attributes. However, aged loins were rated saltier than loins not aged. Additionally, aged loin chops tended to have a greater intensity score for mutton and green attributes. Aldehydes were the greatest proportion of the volatile aroma compound chemical classification recovered and identified from the lamb samples. Dry-aged lamb loins yielded greater thiobis-methane (a sulfurous, fishy aroma) than loins without ageing. As expected, muscle fiber tenderness as evaluated by sensory panel was greater for aged loin chops than no age (12.7 and 10.0, respectively). Aged loin chops tended to be juicier as well. Aging in aerobic conditions for up to 14 d can improve tenderness in lamb without significantly impacting flavor, however, there is a tendency to increase the mutton and green flavors with dry aging.

Investigating the Probiotic Potential of Vegan Puree Mixture: Viability during Simulated Digestion and Bioactive Compound Bioaccessibility.

This study aimed to develop a fermented puree mixture containing plant-based ingredients and potential probiotic strains Lacticaseibacillus rhamnosusK3 and Lactobacillus johnsonii K4. The survival of potential probiotic strains, changes in sugar and organic acid concentrations, bioaccessibility of polyphenols, and antioxidant capacity after simulated digestion were examined with sensory quality. The mixture of apple puree, chia seeds, and oat bran or oat flakes was fermented. The sensory quality of the puree mixture was assessed by the quantitative descriptive profile (QDP) method. In vitro digestion was simulated using a static gastrointestinal model. Antioxidant capacity and total polyphenol content were analyzed before and after the digestion phases. All samples changed sensory profiles after fermentation. The overall quality was above six out of ten for every product. Fermentation also changed the organic acid composition, with significant increases in lactic, succinic, and acetic acids. After the digestion process, the survival rate remained above 5.8 log10 CFU/g. As a result of fermentation with potential probiotics, the bioaccessibility of the total phenolics and antioxidant activity increased. These results showed that the addition of potential probiotic strains increases nutritional value and could help with healthy nourishment habits. This knowledge can guide the development of consumer-satisfying products in the food industry, expanding the probiotic food market with innovative alternatives.

How does the inclusion of a companion forage alongside perennial ryegrass influence production performance, sensory perception and consumer liking of lamb meat?

In sheep production systems, diet type is an important factor affecting the eating quality of the meat produced. The objective of this study was to assess the effect of binary swards on the slaughter performance, descriptive sensory profile, consumer liking and instrumental texture of lamb meat. Five dietary treatments were investigated, perennial ryegrass (Lolium perenne L.; PRG), PRG plus white clover (Trifolium repens L.; PRG+WC), PRG plus red clover (Trifolium pratense L.; PRG+RC), PRG plus chicory (Chicorium intybus L.; PRG+Chic) and PRG plus plantain (Plantago lanceolata L.; PRG+Plan). Post – weaning sixty Texel sired crossbred lambs (n = 12 per dietary treatment) were selected from the main cohort of lambs born in 2022 and further balanced for sex and reared litter size. The M. longissimus thoracis et lumborum (LTL) was obtained from each lamb post-slaughter. Meat samples were analysed by a trained sensory panel, a consumer panel as well as Warner-Bratzler shear force (WBSF) measurements. All data were analysed using a linear mixed model PROC MIXED in SAS. Mean slaughter weights of 46.0 ± 0.36 kg and cold carcass weights of 22.2 ± 0.51 kg were achieved with no differences observed across dietary treatments (P > 0.05). On average, lambs were 217 d of age at slaughter. Lambs finished on PRG and PRG+Plan had similar growth rates, however binary mixtures containing PRG plus any one of WC, RC (P < 0.01) or Chic (P < 0.05) increased average daily gain (ADG) and reduced the number of days required for lambs to reach slaughter (P < 0.05), relative to lambs grazing the PRG monoculture. Meat from PRG+Plan lambs was scored lower by the trained sensory panel for initial tenderness (P < 0.001) and overall tenderness (P < 0.001) when compared to meat from any other dietary treatment. Consumers scored meat from PRG or PRG+WC lambs higher for tenderness (P < 0.05) and flavour (P < 0.01) in comparison to meat produced from PRG+Plan lambs. Relative to meat from PRG+Plan lambs, PRG, PRG+WC and PRG+Chic lamb meat scored higher for overall liking (P < 0.01) when assessed by the consumer panel. Results show that companion forage inclusion increased lamb growth performance in the post-weaning period thus reducing age at slaughter. However, findings suggest that the addition of plantain to the grazed sward may negatively affect the eating quality of lamb meat, highlighting the need to consider diet type in tandem with meat eating quality when selecting finishing systems for pasture fed lambs.

Personality and Well-Being Across and Within Relationship Status.

Trends of increasing singlehood call for understanding of well-being correlates across and within relationship status. While personality is a major predictor of well-being, descriptive trait profiles of singles have not been developed. In the present research (N = 1,811; 53% men; Mage = 29), single and partnered individuals completed measures of personality and well-being, including life, relationship status, and sexual satisfaction. Results revealed effects whereby single individuals were lower in extraversion and conscientiousness but higher in neuroticism. Additional facet analyses showed that singles were lower across all extraversion facets, but specifically lower in productiveness (conscientiousness facet) and higher in depression (neuroticism facet). Largely, personality was associated with well-being similarly for single and partnered people. Furthermore, relationship status accounted for variance in well-being above and beyond personality traits. Our results suggest individual differences in personality could play an important role in understanding well-being's link with relationship status.

Oat-based milk alternatives: the influence of physical and chemical properties on the sensory profile.

Oat-based milk alternatives (OMAs) have become increasingly popular, perhaps due to their low allergenicity and preferred sensory attributes when compared to other milk alternatives. They may also provide health benefits from unique compounds; avenanthramides, avenacosides, and the dietary fibre beta-glucan. This has led to a variety of commercial options becoming available. Being a fairly new product, in comparison to other plant-based milk alternatives (PBMAs), means little research has been undertaken on the sensory profile, and how it is influenced by the physical and chemical properties. This study investigated the sensory, physical and chemical profiles of current commercially available OMAs, that varied in fortification, use of stabilisers, and oat content. The volatile compounds and their respective aromas were analysed using solid phase microextraction followed by gas chromatography mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). Liquid chromatography mass spectrometry (LC-MS) was used for identification of avenanthramides and avenacosides. Particle size and polydispersity index (PDI) were analysed using a Mastersizer and Zetasizer, respectively, with colour analysis carried out using a colourimeter, and viscosity measurements using a rheometer. Descriptive sensory profiling was used to assess the impact on the sensory characteristics of the different samples and the sensory data acquired were correlated with the instrumental data. Samples with smaller particle size appeared whiter-both instrumentally and perceptually. The only clear plastic packaged product differed substantially in volatile profile from all other products, with a higher abundance of many volatile compounds, and high overall perceived aroma. Avenanthramides and avenacosides were present in all samples, but differed significantly in abundance between them. The results suggested smaller particle size leads to whiter colour, whilst differences in processing and packaging may contribute to significant differences in aroma. Astringency did not differ significantly between samples, suggesting that the variation in the concentrations of avenacosides and avenanthramides were below noticeable differences.

Weighted and Choquet $$L^p$$ distance representation of comparative dissimilarity relations on fuzzy description profiles

AbstractWe consider comparative dissimilarity relations on pairs on fuzzy description profiles, the latter providing a fuzzy set-based representation of pairs of objects. Such a relation expresses the idea of “no more dissimilar than” and is used by a decision maker when performing a case-based decision task under vague information. We first limit ourselves to those relations admitting a weighted $$\varvec{L}^p$$ L p distance representation, for which we provide an axiomatic characterization in case the relation is complete, transitive and defined on the entire space of pairs of fuzzy description profiles. Next, we switch to the more general class of comparative dissimilarity relations representable by a Choquet $$\varvec{L}^p$$ L p distance, parameterized by a completely alternating normalized capacity.

Evaluating the sensory properties of hybrid (meat and plant‐based) burger patties

AbstractConsumer interest in alternative plant‐based foods is growing, including products where plant proteins are isolated and reformulated to mimic meat. This study aims to investigate the fundamental changes in sensorial (textural) properties between meat and plant proteins using a hybrid protein burger matrix. Burger patties were used as a model, prepared with a range of protein composition (beef: plant‐based protein; 100:0, 75:25, 50:50, 25:75, and 0:100) with identical added fat (17%) and at two salt (0 and 0.6%) contents. Conventional sensory descriptive profiling elicited 21 sensory attributes and profiles of samples were obtained to explore relationship(s) with composition. Early‐stage oral processing texture attributes were well‐differentiated across the sample space, while less discrimination was observed across samples for latter stage mastication texture attributes. Animal meat content increased scores for saltiness and flavor intensity indicating that plant‐based meat analogues require a higher salt content to achieve similar levels of salt and flavor perception. These findings provide key insights into the impact of meat and/or plant‐based protein composition on sensory properties in a hybrid burger patty model system. Future work should consider the mechanical properties of such products with the objective of finetuning ingredients and processing to obtain meat analogues with desirable sensorial attributes.
