Development of chicken tender pops by utilizing pomegranate peel powder.

Pomegranate peel powder (PPP) is a rich source of many bioactive components particularly polyphenols that are interlinked to various technological and functional properties. In the present study, chicken tender pops were developed with incorporation of PPP, and its effect on quality attributes and storage stability of the product were evaluated. The treatments were formulated using 0%, 3%, 6%, and 9% PPP in replacement of chicken. The physicochemical properties, texture profile, instrumental color, sensory attributes, and storage stability were assessed for 21 days at refrigeration temperature, at a regular interval of 7 days. The results indicated that the inclusion of PPP significantly (p < .05) increased the dietary fiber from 0.25% in T0 to 1.45% in T3 at Day 0 and WHC 43.60% ± 0.02 in T0 to 49.36% ± 0.02 in T3 at Day 0, whereas the moisture content significantly reduced from 60.05% ± 0.03 in T0 to 55.08% ± 0.01 in T3 at the start of the study. In addition, the values of TBARS were significantly (p < .05) reduced for treated samples 0.72 mg MDA/Kg in T3 as compared to control 1.17 mg MDA/Kg on the 21st day of storage, whereas a significant increase (p < .05) in TPC from 0.90 mg GAE/g to 3.87 mg GAE/g in T0 to T3 was observed at the start of the study. For TPA, a significant (p < .05) increase was noticed in hardness, chewiness, and gumminess, whereas cohesiveness and springiness showed a non-significant (p > .05) change in treated samples in relation to control, and the instrumental color (L* and a*) decreased significantly. However, pH, crude fiber, fat, ash, and protein content showed non-significant (p > .05) variations over time. The sensory evaluation suggested that chicken tender pops supplemented with 6% PPP (T2) presented high overall acceptability and balanced organoleptic properties. Hence, it can be concluded that PPP can be effectively utilized as a natural fiber source, antioxidant, and antimicrobial agent in novel functional foods.

Comparison of Thawing Treatments on Quality, Microbiota, and Organoleptic Characteristics of Chicken Meat Fillets.

The current research attempted to evaluate the impact of various thawing techniques (R0: control group, R1: water immersion thawing, R2: low-temperature thawing, R3: combined thawing, water thawing then low-temperature thawing, R4: combination thawing, low temperature thawing then water thawing, and R5: oven thawing) on the quality, microbiota, and organoleptic characteristics of chicken meat fillets. The findings showed that moisture content varied from 74.43 to 72.33%; thawing loss peaked in R1 at 4.66%, while it was minimum in R5 at 2.10%. Lipid content varied from 1.09% in R0 to 1.03% in R5, while protein content varied from 22.06% in R0 to 23.10% in R1. The values of shear force, protein, and lipid oxidation increased for all treatments compared to control, ranging from 7.94 N to 9.54 N, 0.99-1.21 nm/mg protein, and 0.74-1.15 mg MDA/Kg, respectively. On the other hand, pH (5.94 in R4) and protein solubility (238.63 mg/g in R1) were decreased in contrast to the control group (6.08 and 298.27 mg/g). In association with different methods, R5 and R2 showed minimal thawing loss and the highest lipid and protein oxidation rates. However, R3 showed reduced shear force and lipid oxidation comparatively. TPC was significantly (P < 0.05) increased in both R2 and R1. Sensory evaluation indicated that R3 and R2 showed better color and taste, while R1 showed minimum scores for organoleptic attributes. R0, R3, and R5 obtained a higher sensory score, whereas R1, R2, and R4 showed a lower score. However, R5 exhibited better results in close association with the control group (R0). Hence, it can be concluded that freezing and subsequent thawing decrease the quality of chicken fillets due to the time required for thawing. In the present study, the best quality of chicken fillets was retained by R3 and R5 due to their reduced thawing periods.

Supplementation of PUFA extracted from microalgae for the development of chicken patties.

In recent years, there has been a growing interest in development of a diverse range of foods that are enriched with omega-3 fatty acids. It is widely recognized that through dietary interventions, the lipid fraction of food can be modified to enhance its nutritional content. This study is aimed to develop chicken patties enriched with poly unstaurated fatty acids (PUFAs) extracted from microalgae aurintricarboxylic acid (ATA) concentration of 0% (T0), 1% (T1), 2% (T2), and 3% (T3). All treatments were stored at -18 °C for one month and analysed at an interval of 0, 10, 20, and 30 days to assess the effect of PUFAs supplementation on physicochemical, oxidative, microbiological and organoleptic properties of chicken patties. The results revealed that moisture content was significantly increased during the storage; the maximum moisture was observed in T0 (67.25% ± 0.03) on day 0, while the minimun was found in T3 (64.69% ± 0.04) on day 30. Supplemenatation of PUFAs in chicken patties significantly enhanced the fat content of the product the highest fat content was observed for T3 (9.7% ± 0.06. An increase in PUFAs concentration led to a significant increase in thiobarbituric acid reactive substances (TBARS). TBARS were increased from 1.22 ± 0.43 at 0 days to 1.48 ± 0.39 at 30 days of storage. The PUFAs incorporation negatively effected sensory acceptance of the product ranging from (8.41 ± 0.17 to 7.28 ± 0.12). However, the sensory scores were in acceptable range for supplemented patties as compared to control sample. Treatment T3 depicted the highest nutritional content. The sensory and physiochemical analysis of supplemented patties suggested that PUFAs extracted from microalgae can be used as a functional ingredient in the preparation various meat products particularly chicken meta patties. However, antioxidants should be added to to prevent lipid oxidation in the product.

Nutritional probing and storage stability of papaya jam supplemented with date pit powder.

Jam Quality is a factor robustly influenced by storage conditions. The current research aimed to develop papaya jam with improved nutritional attributes, rheological profile, and shelf-life utilizing date pit powder as a functional ingredient. The effect of date pit powder on the formulated product's physicochemical, microbial, and organoleptic properties was analyzed. Results revealed that overall mineral profile (0.35-1.11%), crude fiber (0.56-2.01%), pH (3.51-3.70%), and antioxidant properties (22.97-30.67%) were significantly increased while water activity reduced (0.77-0.73). Moreover, date pit powder improved the color scores like a*(10.10-10.67), b* (8.13-8.78), L* (25.56-28.09), and textural attributes (Cohesiveness: 0.83-0.90; Firmness: 6.82-6.93) of functional papaya jam. Microbial count reduced from 3.60 × 105-3.06 × 105 cfu/ml by adding date pit powder and staying within the acceptable limit (4.13 × 105-3.60 × 105 cfu/ml) during 2-month storage at refrigeration. Organoleptic evaluation depicted that samples treated with date pit powder scored better than the control, and a sample with 75% pectin replacement was considered best.

Supplementation of banana peel powder for the development of functional broiler nuggets.

Banana peel powder is considered one of the most nutritive and effective waste product to be utilized as a functional additive in the food industry. This study aimed to determine the impact of banana peel powder at concentrations of 2%, 4%, and 6% on the nutritional composition, physicochemical parameters, antioxidant potential, cooking properties, microbial count, and organoleptic properties of functional nuggets during storage at refrigeration temperature for 21 days. Results showed a significant increase in nutritional content including ash and crude fiber ranging from 2.52 ± 0.017% to 6.45 ± 0.01% and 0.51 ± 0.01% to 2.13 ± 0.01%, respectively, whereas a significant decrease was observed in crude protein and crude fat ranging from 13.71 ± 0.02% to 8.92 ± 0.02% and 9.25 ± 0.02% to 4.51 ± 0.01%, respectively. The incorporation of banana peel powder significantly improved the Water Holding Capacity from 5.17% to 8.37%, cooking yield from 83.20 ± 0.20% to 87.73 ± 0.16% and cooking loss from 20.19 ± 0.290% to 13.98 ± 0.15%. Antioxidant potential was significantly improved as TPC of functional nuggets increased ranging from 3.73 ± 0.02 mg GAE/g to 8.53 ± 0.02 mg GAE/g while a decrease in TBARS (0.18 ± 0.02 mg malonaldehyde/kg to 0.14 ± 0.02 mg malonaldehyde/kg) was observed. Furthermore, functional broiler nuggets depicted a significantly reduced total plate count (3.06-4.20 × 105 CFU/g) than control, which is likely due to high amounts of phenolic compounds in BPP. Broiler nuggets supplemented with 2% BPP (T1) received the greatest sensory scores in terms of flavour, tenderness, and juiciness. Results of current study revealed the potential of BPP to be utilized as an effective natural source of fibre supplementation in food products along with enhanced antioxidant and anti-microbial properties.
