In this study, the pH, total volatile base nitrogen (TVB-N) amounts, total viable counts (TVC) of microbial flora, and the sensory quality of liquid-smoked tilapia fillets were analyzed under different storage conditions. Lengthy storage caused, the smoked flavor to disappear and juice seeped from the samples. Over time, it was found that the pH of the products decreased and then subsequently increased, whilst the amount of TVB-N showed an overall increasing trend. Under all storage conditions tested, the TVC of microbial flora slowly increased, followed by a sharp increase, and then stabilized. These results showed that vacuum-packed products stored at low temperatures were highly stable; hence this storage method can effectively guarantee the quality of liquid-smoked tilapia fillets and the extension of the shelf life.

Freshly harvested capsicum has limited shelf life (5-6 days) under ambient storage conditions. The functional quality of capsicum has been assessed in two sizes (300g±10%) and (900g±10%) of 30µ flex freshTM expanded polyethylene biopolymer pouches at 3 and 10oC and 90-95% RH under modified atmospheric storage. In both small and big size pouches, composition of oxygen and carbon dioxide varied from 18.8-19.9% and 18.8-19.4% and from 2.2-0.7% and 2.0-1.4%, respectively during 28 days of storage at 3oC. Positive and significant correlation was observed between overall acceptability and CO2 composition however, negative correlation was observed with O2 composition. Minimum increase (6.02% and 4.35%) in PLW, minimum decrease in firmness (4.71N-3.50N and 4.71N-2.70N), minimum decrease in chlorophyll (70.3% and 75.5%) and minimum losses (47.6% and 40.3%) of ascorbic acid were obtained after 28 days of storage in small and big size capsicum, respectively at 3oC. The decrease in total phenol and antioxidant activity was 82.4% and 78.6% and 60.1% and 59.4%, respectively after 28 days of the storage at 3oC of small and big size capsicum, respectively. Judges observed most acceptable consistency and OAA score for both sizes of capsicum in pouches up to 21 days of storage at 3oC.

This work evaluated the efficacy of pomegranate byproducts, specifically peel powder, as valid preservatives for food quality. Ready-to-cook cod sticks breaded with pomegranate peel powder were prepared. Shelf-life tests were conducted on breaded cod sticks during refrigerated storage (17 days) at 4 °C, monitoring the pH, microbiological and sensory quality. In addition, the nutritional quality of both the breaded and control samples was assessed. The results highlighted that active samples showed higher phenol and flavonoid content and higher antioxidant activity compared to the control fish, suggesting that pomegranate peel powder was responsible for a significant increase in cod stick nutritional quality. Furthermore, the cod stick active breading led to a delay in microbial growth without affecting the sensory properties; rather, it helped slow down the sensory attribute decline during the refrigerated storage. The data suggest that using pomegranate byproducts in breaded cod stick was effective in prolonging its shelf life, as well as improving its nutritional quality. Therefore, pomegranate peel powder can be considered as a potential resource as natural food preservative.
