Development of freshness indicator for monitoring chicken breast quality and freshness during storage.

ABSTRACT: An indicator for freshness and quality measurement was utilized to perceive changes in freshness quality while storing chicken breasts. Visible color changes of the indicator shows spoilage and freshness of the packaged products. In addition, changes in pH, volatile basic nitrogen (VBN), and Pseudomonas spp. were monitored. The color change sensor (ΔE) reflected the headspace pH during the chicken breasts' packaging process. After storing chicken breast at 20 °C for 24 h, the color change (ΔE) of the indicator for freshness and quality measurement changed. The color change (ΔE) values were correlated with quality characteristics such as sensory, microbiological, and chemical properties that were popularly used to settle the freshness of chicken breast. In conclusion, the results showed that the indicator for freshness and quality measurement was useful in settling the shelf life of chicken breast products by physicochemical changes and monitoring microbial safety.

Project description:Acidic marinades are commonly used to improve the quality meat products. However, no study has been performed to determine the effects of rhubarb juice as a marinating liquid on the quality parameters of chicken breast fillets. The aim of the present study was to identify the bioactive compounds (organic acids, polyphenols, and volatiles) in the juice of rhubarb and to determine the effect of rhubarb juice as a marinade on the microbiological (total viable count, psychrotrophs, lactic acid bacteria, sulfate-reducing anaerobes, and yeast-molds) and physico-chemical properties (drip loss, cooking loss, water holding capacity, pH, color, malondialdehyde, total volatile base nitrogen, and texture profiles), sensory attributes, and microbial safety (Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes) of chicken breast fillets during a 15-day refrigerated storage. The experiment included five groups: a control (no treatment), and marinated groups treated with 50 % and 100 % rhubarb juice for 6 and 24 h. The application of a rhubarb juice-based marinade (100 % for 24 h) resulted in a significant decrease in the number of E. coli O157:H7, S. Typhimurium and L. monocytogenes by 1.67 to 2.60 log10 cfu/g compared to the control group (P < 0.05). In addition, this marinade significantly reduced the growth of psychrotrophs, lactic acid bacteria and the total number of viable bacteria compared to the control group during storage (P < 0.05). The rhubarb juice-based marinade significantly delayed the increase in spoilage microorganisms and oxidation parameters compared to the control fillets (P < 0.05). No differences were found between the control and treatment groups in terms of sensory evaluation (P > 0.05). In conclusion, the results show that the juice of rhubarb juice contains a variety of organic acids, polyphenolic compounds and volatiles that contribute to antioxidant capacity and antimicrobial activity. In addition, the use of rhubarb juice as a marinating liquid delayed the oxidation of proteins and lipids, the growth of spoilage microorganisms and improved microbial safety by inhibiting foodborne pathogens in the chicken breast fillets.
