Effect of sight on the evaluation and acceptance of new products: Breaded nuggets with breadcrumbs and a new seasoning

The main aim of this study is to examine the influence of chicken nugget color and appearance on the overall acceptance rates and responses of a panel of consumers. Fifty blindfolded and fifty-two non-blindfolded panelists tasted the nuggets. They evaluated their Overall Liking (OL) and their perceptions of the sensory properties of chicken nuggets with no seasoning and chicken nuggets coated in breadcrumbs with 10% and 25% of a red pomace seasoning, a by-product of red winemaking. Just-About-Right (JAR) scales and Penalty Analysis (PA) were then used to determine the adequacy of the sensory attributes that the consumers had attributed to the products. Furthermore, purchase intention was also studied. The red pomace seasoning, regardless of the quantity that was used, darkened the nugget coatings. No effect of color on OL was observed when comparing the responses of the blindfolded and the non-blindfolded consumers. Their purchase intention decreased in proportion to the increased amount of seasoning added to the breadcrumbs. However, PA suggested that nuggets coated in breadcrumbs with 10% red pomace seasoning could after some reformulation be successfully marketed.

Characterization and genomic analysis of the lytic bacteriophage vB_EclM_HK6 as a potential approach to biocontrol the spread of Enterobacter cloacae contaminating food

BackgroundIncreased prevalence of Enterobacter cloacae within food products underscores food as an underexplored reservoir for antibiotic resistance, thus requiring particular intervention. Bacteriophages have been explored as a promising approach for controlling bacterial growth in different matrices. Moreover, their specific interaction and self-replication, put them apart from traditional methods for controlling bacteria in different matrices.MethodsSixteen Enterobacter cloacae strains were recovered from raw chicken. These strains were used to isolate bacteriophages using enrichment protocol. The broad-spectrum bacteriophage was evaluated in terms of thermal, pH, shearing stress and storge. Moreover, its infection kinetics, in vitro antibacterial activity, cytotoxicity were also assessed. Genomic sequencing was performed to exclude any potential virulence or resistance genes. Finally, the capability of the isolated phages to control bacterial growth in different chicken samples was assessed alone and in combination with sodium nitrite.ResultsThe lytic bacteriophage vB_EclM_HK6 was isolated and showed the broadest spectrum being able to infect 8/16 E. cloacae strains with a lytic activity against its host strain, E. cloacae EC21, as low as MOI of 10–6. The phage displays a latent period of 10 min and burst size of 115 ± 44 and resistance frequency of 5.7 × 10–4 ± 3.0 × 10–4. Stability assessment revealed a thermal tolerance up to 60 ˚C, wide range pH stability (3–10) and the ability to withstand shearing stress up to 250 rpm. HK6 shows no cytotoxicity against oral epithelial cells up to 1012 PFU/ml. Genomic analysis revealed a Strabovirus with total size of 177,845 bp that is free from known resistance and virulence genes. Finally, HK6 pretreatment of raw chicken, chicken nuggets and ready-made cheese salad shows a reduced bacterial count up to 4.6, 2.96 and 2.81 log-units, respectively. Moreover, combing HK6 with sodium nitrite further improved the antibacterial activity in both raw chicken and chicken nuggets without significant enhancement in case of cheese salad.ConclusionEnterobacter bacteriophage vB_EclM_HK6 presents a safe and effective approach for controlling E. cloacae contaminating stored chicken food samples. Moreover, they could be combined with a reduced concentrations of sodium nitrite to improve the killing capacity.

Chemical Quality (Water Content, Protein, Fiber) and Organoleptic Properties of Chicken Nuggets with Addition of Vegetables

This study aimed to assess the chemical quality (moisture content, protein, and fiber) and organoleptic properties of chicken nuggets with the addition of vegetables. The materials used included chicken breast, wheat flour, tapioca flour, bread crumbs, eggs, pepper, salt, ice water, carrots, broccoli, spinach, and young corn. Five treatments were applied: P0 (no vegetable addition), P1 (carrot addition), P2 (broccoli addition), P3 (spinach addition), and P4 (young corn addition). The research employed a Completely Randomized Design (CRD) for analyzing chemical quality and a Randomized Block Design (RBD) for examining organoleptic properties. Preferences were tested using the Kruskal-Wallis test. The chemical quality measurements included moisture content, protein, and crude fiber, while the organoleptic measurements assessed color, aroma, texture, taste, and preference. The results showed that the addition of vegetables significantly (P0.05) affected moisture content but had no significant effect (P0.05) on protein and fiber content. Furthermore, the addition of vegetables significantly (P0.05) influenced the color, aroma, and taste of the nuggets, but did not significantly affect (P0.05) texture and preference. It was concluded that incorporating 10% vegetables into chicken nuggets increased moisture content without affecting protein and fiber levels or overall preference. The addition of carrots yielded the highest scores for aroma and taste preference.

Assessing textural changes of breaded deep‐fat fried chicken nuggets during post‐frying holdings under infrared heat‐lamp using acoustic‐mechanical techniques

SummaryTexture is a multi‐parameter attribute and one of the prime quality attributes of fried products. This study examined the influence of post‐frying holdings under a heat lamp on the texture of breaded fried chicken nuggets. Chicken nuggets were deep‐fat fried (2, 4, 6, and 8 min) in canola oil at 180 °C. The fried samples were kept under an infrared heat lamp for up to 1 h, and the textural characteristics were compared with samples not exposed to post‐frying holdings. Textural characteristics were analysed through mechanical‐acoustic approach. The mechanical‐acoustic parameters related to crispiness analysed included maximum force (Fmax, N), number of force peaks (NFP), the area under force‐deformation curves (AF, N.sec), sound pressure level (SPL, dB), number of sound peaks (AUX) and the area under the amplitude‐time plots (AS, dB.sec). The mechanical parameters (Fmax: 19.11–48.96 N; NFP: 5–40; AF: 43–135 N.sec) of chicken nuggets increased with frying time, and these attributes were decreased during post‐frying holding. Similarly, acoustic parameters (SPL: 64.75–90.67 dB; AUX: 180–795; AS: 63–98 dB.sec) of chicken nuggets increased with frying time, and these attributes were decreased during post‐frying holding. Considering the studied parameters, 6 min of frying was found as optimal frying time. However, the post‐frying infrared heat lamp treatment affected the mechanical textural parametres more than the acoustic parameters. Findings from this study will be useful to food industries in optimising textural retention during post‐frying heat lamp holdings of fried products.

Unravelling the nexus between structure, texture, and acoustic traits of fried chicken nuggets

SummaryTexture is a multi‐parameter attribute and one of the prime quality attributes of fried products. This study explored the nexus between microstructure and texture of fried breaded chicken nuggets. Chicken nuggets were deep‐fat fried (2, 4, 6, and 8 min) in canola oil at different frying temperature (170, 180, and 190 °C). Microstructure and texture of fried samples were assessed by scanning electron microscopy (SEM) and acoustic‐mechanical texture analyser, respectively. Maximum force (Fmax), number of force peaks (NFP), area under force‐deformation plots (FA), sound pressure level (SPL), number of sound peaks (AUX), and area under amplitude‐time curves (SA) were used to describe the textural parameters. Microstructural indices (porosity, number of pores, average pore area, polydispersity index, and average shape factor) were estimated from the SEM images. Results revealed that, both the frying time and temperature were positively correlated with the mechanical (Fmax: 25–55 N, NFP: 05–74 N, FA: 6500–15 000 N.sec) and acoustic (SPL: 88–97 dB, AUX: 650–810 dB, SA: 380–405 dB.sec) parameters. Frying time and temperature significantly (P < 0.05) impacted the formation of micropores in fried chicken nuggets. Crust microporosity showed strong positive correlations (r = 0.82) with the AUX value. The NFP, SPL, and SA of the fried nuggets were significantly (P < 0.05) impacted by the crust microporosity. Crust porosity (10–30%), number of pores (8–400), average pore area (10–4000 μm2), polydispersity index (0.05–0.2), and average shape factor (0.8–1.1) of fried nuggets were significantly (P < 0.05) influenced by both the frying time and temperature. Findings from this study would be useful in quality improvement and process monitoring including modelling of coated fried products.

Utilizing foam-structured hydroxypropyl methylcellulose oleogels with curcumin for deep-fried chicken nuggets in carnauba wax-canola oil oleogel

In this study, foam-structured hydroxypropyl methylcellulose was used to structure cod liver oil into oleogel. Different concentrations of curcumin (0, 1.1, 2.2, 3.3, and 4.4 mg/100g of chicken nuggets) were added to the oleogels and incorporated into the chicken nuggets. Subsequently, samples were deep-fried in an oleogel frying medium prepared with carnauba wax and canola oil (10g/100g). Our results revealed that the addition of 4.4 mg/100g of curcumin led to the highest fat uptake reduction and moisture retention compared to the control and 1.1 mg/100g of curcumin (P < 0.05). Additionally, the addition of 4.4 mg/100g of curcumin exhibited consistently higher oxidative stability, as indicated by thiobarbituric acid reactive substances (TBARS), during the 30-day storage period at −18 °C compared to the control (P < 0.05). Notably, treated samples did not show any alteration in ash and protein contents, color, texture, pH values, sensory attributes, or microscopic structures of the fried chicken products. Furthermore, fatty acid analysis revealed that the samples containing 4.4 mg/100g of curcumin had significantly lower levels of saturated fatty acids and higher levels of monounsaturated and polyunsaturated fatty acids than the control (P < 0.05). Overall, the study demonstrates that adding curcumin in a carrier setting to deep-fried chicken products can improve the products by reducing fat uptake and extending oxidative stability.

&lt;i&gt;Citrus reticulata&lt;/i&gt; flavonoids as a valuable source for reducing meat-borne &lt;i&gt;Aeromonas hydrophila&lt;/i&gt;

Meat products are one of the nutritious diet options available to consumers. However, meat products have the potential to serve as a reservoir of food-borne infections, such as those caused by Aeromonas species, which pose a significant risk to public health. A total of 270 samples, 30 of each minced beef, meatball, beef burger, chicken nuggets, chicken pane, chicken burger, canned anchovy, canned mackerel, and canned sardine, were obtained from supermarkets in Aswan Province, Egypt, to analyze the occurrence and virulence features of Aeromonas hydrophila. Influence of Citrus reticulata peel extract on the A. hydrophila count and its virulence capacity after different marinating periods was also analyzed. The obtained results revealed that the Aeromonas counts ranged from 2.02±0.30 to 4.21±0.27 log10 CFU/g and 37% of the analyzed samples were contaminated with Aeromonas spp. The main strains discovered were A. hydrophila (13.3%), A. sobria (9.6%), A. caviae (7.4%), A. veronii (4%), and A. fluvialis (2.6%). It was found by polymerase chain reaction that all tested strains (n = 36) belonged to Aeromonas spp., and 89% were identified as A. hydrophila. In contrast, virulence genes aerolysin (aerA) and cytotoxic enterotoxin (act) were found in 61.1% and 50% of the tested isolates, respectively, with a wide range of antibacterial resistance. Additionally, the influence of Citrus reticulata peel extract on A. hydrophila counts at different marinating periods declined significantly with increased concentration without major changes in the sensory criteria.

Mapping ultra-processed foods (UPFs) in India: a formative research study

BackgroundIncreased consumption of ultra-processed foods (UPFs) which have additives such as artificial colours, flavours and are usually high in salt, sugar, fats and specific preservatives, are associated with diet-related non-communicable diseases (NCDs). In India, there are no standard criteria for identifying UPFs using a classification system based on extent and purpose of industrial processing. Scientific literature on dietary intake of foods among Indian consumers classifies foods as unhealthy based on presence of excessive amounts of specific nutrients which makes it difficult to distinguish UPFs from other commercially available processed foods.MethodsA literature review followed by an online grocery retailer scan for food label reading was conducted to map the types of UPFs in Indian food market and scrutinize their ingredient list for the presence of ultra-processed ingredients. All UPFs identified were randomly listed and then grouped into categories, followed by saliency analysis to understand preferred UPFs by consumers. Indian UPF categories were then finalized to inform a UPF screener.ResultsA lack of application of a uniform definition for UPFs in India was observed; hence descriptors such as junk-foods, fast-foods, ready-to-eat foods, instant-foods, processed-foods, packaged-foods, high-fat-sugar-and-salt foods were used for denoting UPFs. After initial scanning of such foods reported in literature based on standard definition of UPFs, an online grocery retailer scan of food labels for 375 brands (atleast 3 brands for each food item) confirmed 81 food items as UPFs. A range of packaged traditional recipes were also found to have UPF ingredients. Twenty three categories of UPFs were then developed and subjected to saliency analysis. Breads, chips and sugar-sweetened beverages (e.g. sodas and cold-drinks) were the most preferred UPFs while frozen ready-to-eat/cook foods (e.g. chicken nuggets and frozen kebabs) were least preferred.ConclusionIndia needs to systematically apply a food classification system and define Indian food categories based on the level of industrial processing. Mapping of UPFs is the first step towards development of a quick screener that would generate UPF consumption data to inform clear policy guidelines and regulations around UPFs and address their impact on NCDs.

“That Looks Like My Kitchen!” − Personalized context by usage frequency and familiarity influences consumer perception and liking of chicken nuggets in VR

Restoring relevant context during consumer sensory testing using virtual reality (VR) technologies may facilitate evaluations reflective of real-world experiences, enabling reliable data collection to better predict product success. Prior research has applied the same consumption scenario to all participants without accounting for variations in individual consumption habits. Thus, a consumption scenario of low personal relevance can lead to misleading conclusions. This study aimed to investigate how personal relevance (usage frequency and similarity) of a consumption environment influences consumer perception and acceptance during product evaluations. Using a VR system, 63 consumers evaluated four commercial frozen chicken nuggets in three virtual environments one week apart: sensory booth, high-relevance kitchen, and low-relevance kitchen. Participants assessed the products virtually on overall liking, Check-All-That-Apply (CATA) on 20 attributes, and purchase intent. They also completed a virtual presence and engagement questionnaire after testing. Results found better product discrimination in both kitchen environments compared to the booth as demonstrated in more post-hoc statistical subgroups (p’s < 0.05) on liking and purchase intent. Additionally, more significant product differences were found among CATA attributes in the kitchens. CATA penalty-lift analyses indicated that sensory attributes had more pronounced positive and negative impacts on liking in the high relevance kitchen, followed by the low relevance kitchen, and lastly the booth. Consumers were equally present and engaged during testing across conditions (p’s > 0.05). Results suggest providing a personally relevant consumption environment via VR technologies for consumer testing generated more discriminating data that can improve the quality of consumer insights.

The popular nuggets is chicken nuggets which have a high fat content and cholesterol which is harmful for health. Currently there are developments of high-fiber nugget innovations through the optimization of tempeh and oyster mushrooms This study aims to analyze the proximate to determine the water content, protein content, carbohydrate content, fat content, and ash content in tempeh nuggets with the addition of oyster mushrooms. The method in this study uses an experimental method carried out in the laboratory by analyzing the water content, carbohydrate content, fat content, ash content, and protein content of the nuggets. Based on the research that has been conducted, the average results of the highest water content of tempeh nuggets combined with oyster mushrooms is in the S3 treatment (51.75%), protein content in the S3 treatment (13.747%), fat content in the S2 treatment (13.69%), ash content in the S1 treatment (6.057%) and carbohydrate content in the S1 treatment (27.113%)

Lipid Quality Changes in French Fries, Chicken Croquettes, and Chicken Nuggets Fried with High-Linoleic and High-Oleic Sunflower Oils in Domestic Deep Fryers.

The quality of fried products greatly depends on the changes occurring during frying. The purpose of this work was to study the lipid quality changes taking place in selected frozen foods after domestic deep-frying. Conventional, high-linoleic sunflower oil (HLSO) and high-oleic sunflower oil (HOSO) were used, and the frozen foods selected were French fries, croquettes, and nuggets. The foods were fried in domestic fryers under discontinuous conditions. Analyses included fatty acid composition, sterols, tocopherols, squalene, and lipid alteration levels. In all fried foods, the content of lipids increased after frying, which is consistent with previous findings. However, the lipid exchange between the food and the oil greatly depended on the food characteristics. Specifically, the levels of frying oil in the food lipids were about 90, 40, and 58% for French fries, croquettes, and nuggets, respectively. The main results obtained showed that lipid alteration levels considerably decreased and amounts of sterols and tocopherols significantly increased in French fries' lipids after frying. In both chicken products, croquettes and nuggets, the best quality improvement observed was a significant decrease in cholesterol in food lipids due to the lipid exchange. Overall, frying with HLSO and HOSO improved the quality and nutritional properties of all products tested.

Properties of encapsulated raspberry powder and its efficacy for improving the pH, colour quality and shelf life of modified atmosphere packaged chicken nuggets

ABSTRACT 1. Recent research has shown that encapsulated raspberry powder (RP) is a natural colourant for foodstuffs. However, no research has been conducted on its use in chicken nuggets. In addition, the effect of RP on products with and without phosphate addition is unknown. This study assessed the effects of RP (control, 0.5%, 1.0%) and phosphate (0.0%, 0.3%) on the pH and colour quality properties of nuggets. 2. In the production of RP, red raspberry (Rubus ideaus L.) juices were encapsulated using maltodextrin in a spray-dryer. Antioxidant activity, total anthocyanin, total phenolics, colour, moisture and pH analyses of the RP were performed. 3. Nuggets were packaged in modified atmosphere packaging (MAP; 40%CO2 + 60%N2) and were stored at 2.0 ± 0.5°C for 120 d. The pH and external and internal surface colour (L*, a*, b*, C* and h) values were measured on d 0, 15, 30, 45, 60, 75, 90, 105 and 120 of storage. 4. The addition of phosphate increased the pH in the samples, while these decreased with the addition of RP (p < 0.05). During storage, the highest pH were seen in the phosphate samples and the lowest in the nuggets with 1.0% RP addition (p < 0.05). 5. With the addition of phosphate, the external surface a* value of nuggets increased (p < 0.05). Depending on the level of RP added to the nuggets, the external surface L* value decreased and a* and b* values increased (p < 0.05). After d 30 of storage, the a* value increased in the samples with RP addition and this increase was higher in the with phosphate nuggets (p < 0.05). 6. The internal surface a* value increased with the addition of RP during nugget production (p < 0.05). The increase in a* value was greater in samples with added phosphate (p < 0.05). During storage, the highest a* values were seen in nuggets treated with phosphate + 0.1% RP (p < 0.05). The addition of RP to chicken nugget emulsion improved redness, colour stability and shelf life.

Mushroom-legume-based alternative chicken nuggets: Physico-chemical and sensory properties

The consumer demand for meat analogs (MAs) is on the rise. Soy proteins are frequently used as the primary ingredient in MAs, but soybean may negatively impact human health and cognitive functions. The aim of this research was to develop alternative chicken nuggets using mushroom and chickpea flour. Effect of different sources of mushroom and starch in the textural and sensory quality of nuggets were determined. Phoenix mushroom was chosen based on nuggets' textural and sensory qualities. Different ratios of mushroom and chickpea flour (0:70, 15:55, 55:15, and 70:0, w/w) were tested to prepare the nuggets. Based on protein, textural and sensory qualities compared to chicken and commercial plant-based nuggets, the mushroom to flour ratio of 55:15 was chosen. The results showed that tapioca starch-containing nuggets had a better texture and were more palatable to consumers. The processed nuggets demonstrated lower protein (6.88 vs 11.72%, dry wt. basis) but better cooking yield (87.65 vs 85.29%), moisture retention (77.86 vs 75.16%), fat retention (90.55 vs 88.39%) and higher consumer acceptability than commercially available soy-based nuggets. The results of the study suggest that mushroom and chickpea flour may replace soy protein in meat analogs.

The Effect of Using Aqueous Extract of Cyperus Rotundus Tubers on Characteristics and Shelf Life of Chicken Nuggets

The experiment was conducted to investigate the effect of the aqueous extract of the Cyperus ‎rotundus tubers ‎on fat oxidation and stored frozen chicken nuggets' physical and microbial ‎characteristics. The extract was incorporated into minced poultry meat at concentrations of 0% (control), 0.1%, 0.2%, 0.3%, and 0.4%, and the treated samples were stored for periods of 1 and 30 days at -18°C. The addition of Cyperus rotundus extract significantly improved the pH values and water-holding capacity of the treated nuggets (T2, T3, T4, and T5) compared to the control (T1) across both storage durations. Moreover, a notable reduction in lipid oxidation markers (peroxide value (PV), thiobarbituric acid reactive substances (TBA), free fatty acids (FFA), and total volatile nitrogen (TVN) was observed in the treated samples relative to the control. Additionally, a significant decrease in the total coliform bacteria count was evident in the treated nuggets, which inversely correlated with the concentration of the Cyperus rotundus extract. The findings suggest that the aqueous extract of Cyperus rotundus tubers beneficially affects the quality and safety of chicken nuggets, enhancing their shelf life when stored at -18°C for up to 30 days‎‎‎.
