Kuzgun, Nermin Karaton
The enrichment in terms of fish protein of fast food products is becoming increasingly important day by day. The aim of this study was to determine the shelf life of a new product—fish onion rings—under deep-freezing conditions (−18°C). Minced fish meat (180 g) was combined with minced onion (350 g), water (220 mL), corn flour (50 g), wheat flour (180 g), and salt (20 g), and the mixture was blended with a mixer until a homogeneous texture was obtained. Then, the mixture was shaped into onion rings using a dough-shaping tool (manually). The chemical, sensory, and microbiological quality attributes of the fish onion rings were recorded at 30-day intervals. In the samples, deterioration was observed at the end of the 180th day (as chemical, sensory, and microbiological quality). In the fish onion ring group, the TBA (0.07 ± 0.05–3.02 ± 0.97) and peroxide (0.19 ± 0.18–4.40 ± 0.31) values remained similar during storage. In the microbiological analysis of the experimental fish onion rings, the total viable count (TVC) was 2.63 ± 0.15 on Day 0. Furthermore, the samples underwent sensory evaluation for appearance, odor, and taste. It was determined that the most preferred group was the fish-supplemented group.

Alak, Gonca; Kuzgun, Nermin Karaton
The valorization of industrial fish waste has gained significant scientific interest due to its integrated benefits such as waste management and resource recovery. The aim of this study is to evaluate the effectiveness of fish bones, which is one of the wastes of aquaculture processing and constitutes approximately 9–15% of the waste generated as a result of the process, as a preservative in the food industry within the scope of green chemistry applications, sustainability and green product targets. In line with this objective, in the first stage, hydroxyapatite (HAP) was obtained from the fish bones, in the second stage, chitosan (Ch)-based coating solutions were enriched with HAP at different levels (0.02, 0.04 and 0.08 g / L) and in the last stage, fillets were coated with this solution and fillet quality parameters were monitored by microbiological, chemical and sensory analyses at certain intervals (0, 3, 6, 9 and 12 days) during 12 days of storage (at + 4 °C). Based on the data obtained during the storage period, the shelf life of control (Chitosan, Ch). chitosan + low HAP (Ch + L-HAP) and chitosan + medium HAP (Ch + M-HAP) fillet groups increased by 50%, 26% and 20%, respectively, compared to chitosan + high HAP (Ch + H-HAP). In the findings obtained, it was determined that the high concentration application (Ch + H-HAP) had a negative effect on all the parameters studied in fillets, and when the data on the last day of storage, especially the microbiological results were taken into consideration, it was determined that the shelf life decreased by 20–50% on average compared to the other concentrations (Ch + L-HAP and Ch + M-HAP) and Ch group and caused serious negativities in sensory parameters. Based on this result, it would be useful to try low and medium levels of this compound in different combinations. These findings indicate that HAP-enriched chitosan coatings have potential as a promising delivery system for the effective and controlled transport of bioactive ingredients in the food industry.
