In conclusion, it can be said that the ‘Samsun Güzeli’ genotype performs adequately in terms of fruit yield and quality on the standard dwarf rootstock and conducting new studies might be beneficial to disseminate the genotype.

Analysis of flower volatile compounds and odor classification of 17 tree peony cultivars

As one of the significant ornamental characteristics of tree peony, floral fragrance has garnered considerable attention. In this study, 65 cultivars of tree peony were classified into three groups based on their sensory evaluation scores: strong fragrance, medium fragrance, and no/light fragrance and 9 strong fragrance cultivars, 6 medium fragrance cultivars, and 2 light/no fragrance cultivars were selected for substance analysis. Using gas chromatography-mass spectrometry (GC–MS), 77 volatile organic compounds (VOCs) were identified and classified from 17 tree peony cultivars, they were terpenoids, benzenoids/phenylpropanoids, and fatty acid derivatives. Monoterpenoids were the main volatile compounds in the cultivars ‘Souvenir de Maxime Cornu’, ‘Okan’, ‘Chromatella’, ‘Yapianzi’, and ‘Liuli Guanzhu’, while benzenoids/phenylpropanoids were the main volatile compounds in ‘Shaonvqun’ and ‘Binglingzi’. Through the calculation of odor activity value (OAV), 17 cultivars were categorized into four distinct groups: flower-sweet scent, flower-rose scent, herb scent and mixed scent. This investigation presented the composition and classification of fragrant compounds of 17 tree peony cultivars and classified the odor profiles based on the contribution of flower volatiles to the overall olfactory experience, offering valuable materials for genetic enhancement of tree peony floral fragrance.

Unraveling the Complexities of Beef Marination: Effect of Marinating Time, Marination Treatments, and Breed.

The present study focused on evaluating the effects of beef marination on quality traits and consumer acceptability. In this context, m. longissimus thoracis et lumborum and m. semimembranosus samples (n = 192) were obtained from Aberdeen Angus, Hereford, Charolais, and Limousine bulls and were marinated with milk (pasteurized, 100%), garlic and olive oil (2.35 g/500 mL), and lemon (citrus) juice (31% orange juice, 31% lemon juice, 38% distilled water) for 12, 24, and 72 h. Marinade components were selected based on traditional culinary practices and their scientifically proven effects on meat quality. Beef samples on day 0 and non-marinated samples were used as control groups. Beef color, water holding capacity, pH, cooking loss, and Warner-Bratzler shear force were measured three times for each sample. A taste panel assessment was performed to determine the sensory characteristics. Statistical analysis was performed using general linear model (GLM) procedures followed by Tukey's post-hoc comparison. Results revealed that marination time, as well as its two- and three-way interactions, significantly influenced beef quality parameters. These results indicate that the cattle breed is an important factor in evaluating the effectiveness of beef marination applications. The olive oil-garlic marinade was the most preferred by the panel across both types of muscle, as indicated by sensory evaluation results. The findings will not only enrich the scientific literature but also have practical implications for the beef industry.

Pulsed Light Treatment Effect on Color, Oxidative Stability, and Listeria monocytogenes Population of Sliced Mortadella.

This study evaluated the effects of high-intensity pulsed light (PL) on sliced mortadella, assessing how the parameters pulse width (1260 to 2520 µs) and number of pulses (one to three) influence color, oxidative stability, and Listeria monocytogenes population. The different PL parameters generated a fluence ranging from 2.64 to 6.57 J/cm2 and irradiance ranging from 1046.9 to 1738.8 W/cm2. The PL slightly increased the temperature and pH of the samples, and this elevation was well correlated to the higher number of pulses and higher fluence. The color parameter a* was reduced while b* values increased after PL application, with these effects being more significant in treatments with a higher number of pulses and higher fluence. The highest values of TBARS were found in treatments with higher fluence (5.28 and 6.57 J/cm2), which were characterized by the attribute "oxidized color" in sensory evaluation. The different PL conditions reduced the count of L. monocytogenes by up to 1.44 Log CFU/cm2. The treatment with a pulse width of 1260 µs, two pulses, fluence of 4.38 J/cm2, and irradiance of 1738.3 W/cm2 achieved the same efficacy in pathogen reduction as the treatments with higher fluence. Moreover, these PL conditions had a minimal impact on the color and oxidative stability of mortadella, demonstrating an effective balance between microbiological safety and quality preservation.

Influence of variety and harvest on the sensory characteristics of chocolate made from cocoa fermented with different pulp contents

Despite the long-standing recognition of pulp's impact on cocoa fermentation, studies correlating pulp removal with cocoa variety remain scarce. This study investigates the influence of two cocoa varieties (Parazinho and PS1319) harvested in three different periods and various pulp contents (0–100%) on chocolate's physicochemical and sensory properties. Fermentation was conducted with varying pulp contents, followed by natural drying. The beans were roasted, ground to produce liquor, and mixed with other ingredients, undergoing conching, tempering, and storage to produce chocolate. Sensory evaluations included acceptance tests, CATA (Check-All-That-Apply), and JAR tests. Physicochemical analysis showed no correlation with harvest or variety but differed between samples. Sensory evaluation revealed no significant differences in “aroma” among samples. However, “overall liking” and “flavor” had higher acceptance with partial pulp removal for the PS1319 variety, whereas the Parazinho variety showed no impact. CATA and ideal scale analyses indicated that attributes like “chocolate flavor,” “sweet taste,” “pleasant flavor,” and “pleasant aroma” varied with harvest, variety, and pulp content. In conclusion, partial pulp removal positively impacts certain attributes, enhancing chocolate quality and adding value to pulp, benefiting the cocoa supply chain.

Interaction and dynamic changes of microbial communities and volatile flavor compounds during the fermentation process of coffee flower rice wine.

To develop a unique flavor of rice wine, coffee flowers (by-products of the coffee industry) were added because of their biologically active compounds that are conducive to health, and the fermentation parameters were optimized. In addition, the dynamic changes of microbial communities and volatile flavor compounds (VFCs) during the different fermentation stages were investigated. After the optimization of the fermentation parameters, a novel product, i.e., the coffee flower rice wine (CFRW), was obtained with a bright yellow transparent, fragrant, and harmonious aroma and mellow and refreshing taste by sensory evaluation, when 4.62% of the coffee flowers and 1.93% koji were added and fermented at 24.10°C for 3.88 days. The results showed that Lactococcus was the dominant bacteria, accounting for 87.0-95.7%, while Rhizopus and Cladosporium were the main fungi, accounting for 68.2% and 11.3% on average, respectively, in the fermentation process of the CFRW. Meanwhile, twenty-three VFCs were detected in the CFRW, which included three alcohols, six terpenes, ten esters, three aromatics, and one furan. The correlation analysis revealed that there were 16 significant positive correlations and 23 significant negative correlations between the bacterium and VFCs (|ρ| > 0.6, p < 0.05), while there were 12 significant positive correlations and one significant negative correlation between the fungi and VFCs (|ρ| > 0.6, p < 0.05). Furthermore, five VFCs, including linalool, geraniol, ethyl acetate, 1-hexanol, and 3-methyl-1-butanol, contributed vital flavors to the CFRW, and they were all significantly negatively correlated with the changes of Massilia and Acinetobacter (|ρ| > 0.6, p < 0.05). Moreover a significant positive correlation was found between the relative abundance of Lactococcus and the contents of 3-methyl-1-butanol and ethyl acetate (|ρ| > 0.6, p < 0.05). Therefore, this study provides a valuable theoretical basis for further improving the quality and production technology of CFRW.

Qingqianliutianosides A–E: five new sweet dammarane triterpenoid glycosides derived from the leaves of Cyclocarya paliurus – identification, characterization and interactions with T1R2/T1R3 sweet taste receptors

AbstractBACKGROUNDCyclocarya paliurus, as a new food resource, is utilized extensively in human and animal diets due to its bioactive compounds, health benefits, and its highly prized sweet flavor. This study aimed to investigate the sweet‐taste ingredient of C. paliurus leaves.RESULTSFive new dammarane triterpenoid glycosides were isolated and identified as qingqianliutianosides A–E (1–5) by comprehensive spectroscopic data analysis and a single crystal X‐ray diffraction experiment. Qingqianliutianoside A (1) and qingqianliutianoside C (3), present in relatively high quantities in the plant, were shown to exhibit sweetness by sensory evaluation and electronic tongue analysis. Further monitoring was conducted on the content changes in 3 in leaves at different growth stages, indicating that 3 reached its peak content in April and then showed a decreasing trend. Molecular docking studies revealed that T1R2/T1R3 receptors Ser212, Ser105, Thr239, Asn380, Thr305, and Val381 may play critical roles, demonstrating that hydrogen bonding and hydrophobic interactions were the dominant interaction forces between all of the identified compounds and the active sites in the Venus flytrap module of the T1R2/T1R3 receptors.CONCLUSIONQingqianliutianosides A–E are promising natural source sugar substitutes for use in functional foods and beverages. © 2024 Society of Chemical Industry.

Polyphenolic Profile and Antioxidant Activity of Whole Grape Juices from Vitis labrusca and Brazilian Hybrid Grapes in Two Training Systems.

The phenolic profile and antioxidant activity of whole grape juices from Vitis labrusca and Brazilian hybrids in two training systems were analyzed. Genotypes of V. labrusca ('Bordô' and 'Isabel') and Brazilian hybrids ('IAC 138-22 Máximo' and 'BRS Violeta') were grafted onto the rootstock 'IAC 766 Campinas' (106-8 'Mgt' × Vitis caribaea) and trained on low and high trellis. After harvest, the grapes were destemmed and the berries macerated in a roller crusher. Following hot extraction without pressurization of the pomace and gentle pressing of the blend (skins, must, and seeds), the juices were bottled in amber glass bottles and pasteurized. The physicochemical and colorimetric parameters of the juices, as well as the levels of flavonoids, phenolic compounds, total monomeric anthocyanins, antioxidant activity, and polyphenolic profile, were evaluated. The juices were also subjected to sensory analysis (CAAE: 65549817.7.0000.5411). There was broad variation in all assessed characteristics. The results obtained demonstrate that the training system and grape genotype used in juice production are highly related to the presence of sugars, acidity, and bioactive compounds. Juices made from 'Bordô', 'IAC 138-22 Máximo' and 'BRS Violeta' grapes stood out from 'Isabel' juices, the main grape variety used in Brazilian juice and wine production. All juices contain bioactive compounds in considerable concentrations, indicating beverages with high antioxidant activity and, consequently, high biological potential, with the use of high trellis in vine cultivation potentially increasing concentrations.

The influence of salt reduction with encapsulated oleoresins on the quality of mayonnaise, mustard, and ketchup.

Mayonnaise, mustard, and ketchup are table sauces enjoyed worldwide, adding flavour and texture to many dishes. However, these products often contain high sodium content, which contributes to health issues such as high blood pressure and cardiovascular disease. To address these concerns, reducing salt content in the sauces has become a significant goal for both manufacturers and consumers. This study investigates the effects of three formulations of microencapsulated (ME) oleoresins (F1, F2, and F3), derived from aromatic plants and spices, on the mineral content, physical-chemical properties, colour, and sensory profiles of mayonnaise, mustard, and ketchup. The addition of ME ingredients resulted in significant reductions in salt content across all sauces, with reductions up to 50% in mayonnaise, 45% in mustard, and 52% in ketchup, aligning with EU sodium guidelines and allowing for a "reduced Na/NaCl content" nutrition claim. Potassium levels in mustard and ketchup were sufficient to support health claims related to blood pressure maintenance, while chloride content was reduced in ME formulations, better aligning with dietary reference values. Physical-chemical analysis revealed that ME ingredients had minimal impact on parameters like pH, lipid oxidation, and viscosity, although significant differences were observed in specific areas, such as the consistency of ketchup and chloride content in mustard and ketchup. The use of inulin, as a carrier agent, helped maintain the sauces rheological properties. Mustard showed the most similarity to the control in terms of physical-chemical parameters. Colour analysis indicated minimal changes in mayonnaise, moderate changes in mustard, and significant differences in ketchup, particularly with the ME-F3 formulation, where the light-yellow ME ingredients had a pronounced effect on the darker sauce. Despite these differences, the sensory analysis demonstrated that the overall sensory profiles of the ME formulations were similar the like control for all sauces. Mayonnaise showed the closest resemblance, while mustard had slightly lower scores in flavour and saltiness. Ketchup followed the same trend as mayonnaise, with no significant sensory differences compared to the control. These findings suggest that ME ingredients can be effectively used in condiment reformulation to achieve significant salt reduction without compromising sensory qualities, while also supporting health-related claims. By incorporating ME-based salt reduction strategies and exploring low-sodium alternatives, consumers can continue to enjoy their favourite sauces while minimising sodium intake. Embracing these changes not only benefits personal health but also aligns with the industry's commitment to offering more nutritious options.

The eyes have it: How do gender cues in wine labels influence U.S. women wine consumers?

Little is known about women wine consumers’ reactions to gender cues in marketing communication despite their increasing purchasing power. This research examines the effects of gender cues (feminine vs. masculine) in wine labels on women wine consumers' attitudes, sensory expectations, sensory evaluations, and purchase intentions. Two online experiments and one field test involving 462 valid responses from U.S. women consumers reveal that they hold more favorable attitudes and intentions towards feminine (vs. masculine) wine labels. The moderating effects of in-group gender identification and wine knowledge were discussed. This study responds to calls for more research about women consumers in the hospitality field and extends the application of gender schema theory to hospitality literature. The findings offer updated knowledge on how to approach gender in hospitality marketing, particularly wine marketing. This research enriches hospitality literature in terms of gender marketing and provides substantial practical implications for the wine industry.

Innovative Development of Instant Kombucha Drink and Kombucha Ice Cream Using Spray Drying Techniques

This research focuses on the development of instant kombucha drink and kombucha ice cream using spray drying techniques. Kombucha, a fermented tea known for its health benefits, is processed to halt alcohol production and enhance its usability in various forms. The study utilized three treatment methods to ferment kombucha: Cold shock at ≤ 4°C for 5 days, pasteurization at 72°C for 20 mins and yeast removal using a coffee filter, alongside a standard fermentation control. The spray drying process was applied to kombucha from these treatments to produce instant kombucha powder. The physicochemical properties, nutritional quality and microbial safety of the resulting powder were evaluated. The best results were obtained from pasteurization, yielding a powder with low alcohol content (0.13 % w/w), desirable physicochemical properties (4.70 total dissolved solids, 3.10 pH, 0.2177 titratable acidity) and microbial safety (&lt; 1 CFU/ml). Subsequently, instant kombucha powder was utilized to develop two new products: Instant kombucha drink and kombucha ice cream. The instant drink reconstituted well with water, maintaining the original kombucha's flavour profile and health benefits. The kombucha ice cream was formulated to preserve the bioactive compounds and probiotics, offering a novel health-promoting dessert option. Sensory evaluations indicated high consumer acceptance for both products, with the instant drink and ice cream scoring well on taste, texture and overall satisfaction. The innovative use of spray drying to produce instant kombucha powder and its application in diverse products highlights the potential for expanding kombucha’s market presence while retaining its health benefits.

Synergistic potential of co-millinged edible argan oil (Argania spinosa L.) and oregano leaves (Origanum vulgare L.) in food applications

By including oregano (Origanum vulgare L.) leaves (OL) during the extraction process, the nutraceutical benefits of argan oil (AO) can be significantly increased. Thanks to the employed technique (enrichment through extraction), without resorting to organic solvents. The current work aimed at developing of a green enrichment of argan oil with 2 and 5 % of OL. The purpose of this research was to evaluate the effectiveness of adding OL and its impact on AO oxidative stability under accelerated oxidation for four months. AO physicochemical characterization consisted in measuring quality indices, total phenolic contents, antioxidant activity, pigments, and sensory analysis throughout the storage period. In general, AO samples containing OL exhibited increased phenolic, chlorophylls, and carotenoid contents and lower peroxide and p-anisidine values. AO shelf-life was extended thanks to OL, which slowed down the process of lipid complete oxidation. From a sensory standpoint, a rancid taste was found in the unenriched AO, while the taste and color of oregano were more intense in the AOs supplemented with OL at 5 %. This innovative approach boost AO value in various industries and exemplifies the endless possibilities that emerge when we explore the synergy between different natural elements.

The Influence of Quercus alba Geographical Location and Aging Time on the Chemical and Sensory Quality of Tempranillo Wines.

The changes produced during the aging of wines in oak barrels are strongly dependent on the oak's geographical origin and aging time. This paper analyzes the effect of Quercus alba oak from four different geographical locations in four states in the USA, namely Missouri (Mo), Ohio (Oh), Kentucky (Kt), and Pennsylvania (Py), during 24 months of aging. Oak origin had a higher effect on the wine's aromatic composition than the polyphenolic one. Mo and Oh barrels enhanced coconut, spicy, and sweet notes for 12 months of aging, while Kt barrels achieved higher extraction of wood-related compounds at longer aging (24 months). Py wines showed the lowest contents of most volatile compounds at both aging times, as well as hydroxycinnamic acids, flavanols, anthocyanins, flavonols, stilbenes, and ellagitannins, attributed to their higher porosity. At 12 months of aging, Kt wines showed the highest content of ellagitannins, and Mo wines had the highest content of anthocyanins, but Oh wines had the highest concentrations at 24 months. In the sensory analysis, Kt wines were preferred at both aging times. Kt and Mo wines achieved the highest punctuations for the olfactory phase at 12 months of aging and Kt wines kept it after 24 months. These findings are essential for producers to achieve the sensory characteristics of their wines through strategic barrel aging.

Enhancing the stability of a red organic wine through hydroxytyrosol supplementation at bottling: A time-dependent analysis

The effect of the addition of hydroxytyrosol (HT) in a red organic wine (Sangiovese 85 % and Cabernet Sauvignon 15 %) was evaluated. After six months of storage in a concrete tank, the wines were spiked with HT in three different amounts (30, 60, 120 mg/750 mL in wine) and compared with a control bottled wine (no HT addition). The bottled wines were stored at room temperature and were opened after a period of one, three, six, nine and twelve months to perform chemical and sensory analyses (T1, T3, T6, T9, and T12, respectively). Storage time was the factor that most influenced all wines parameters with respect to the different treatments. However, wine added with 60 and 120 mg/750 mL HT had a lower amount of acetic acid than the control at T3 and T6. At T6, the measured HT was negatively correlated with acetic acid (R2 = 0.81), thus suggesting that HT preserved the wine from oxidation. Later, this trend was not confirmed. The content of HT spiked was stable over twelve months of bottle storage; only the endogenous HT, which is naturally present in wine, showed a decrease of 44 % after twelve months of bottle storage. Yellowness (b*) was higher in the 30 mg/750 mL at T9 compared to the other samples. Lightness (L*) showed a decrement of 11 %, while a* (redness) increased by 21 % from T1 to T12. After T6, the wine fortified with 120 mg/750 mL was preferred by the sensory panel; however, it was the only sample to be clustered by the panel at T9 and "red fruits," "spicy", and "astringency" sensory attributes played an important role in this separation.

Shelf-Life Extension and Quality Changes of Fresh-Cut Apple via Sago and Soy-Oil-Based Edible Coatings

In-demand fresh-cut fruits are highly perishable and require shelf stability. Starch, such as sago, is a naturally available polysaccharide with good gas barrier properties. The study aimed to develop an edible coating and examine the effect of its application on the quality parameters of fresh-cut apples. The coating solution was prepared with sago and soy oil in concentrations of 3, 4, and 5% and 0, 0.25, and 0.50%, respectively. Lecithin (0.50%) was used as an emulsifier and glycerol (1.5%) as a plasticizer. Coated fresh-cut apples were evaluated for physicochemical properties (TSS, pH, non-enzymatic browning index, moisture content, weight loss, headspace gas, and color attributes) during a 12-day shelf-life study at 4 °C. Sensory analysis was also performed to assess consumer acceptability, and microbial analysis to investigate its inhibiting effect against yeast and mold. Compared to the control, developed coatings reduced browning, respiration rate, moisture, weight loss, and microbial load in fresh-cut apples. The study indicates that the blend of 5% sago and 0.5% soy oil produced the best coatings which were most effective for retaining the original quality attributes and in extending the shelf life of apple slices for 12 days in storage at 4 °C.
