Abstract :In this study, the structural features insert ignore into journalissuearticles values(thickness and light transmittance); of edible films that obtained from quinoa starch were analyzed, and the films were applied to rainbow trout fillets. These fillets were classified under two different groups without quinoa starch film insert ignore into journalissuearticles values(control); and coated with quinoa starch film insert ignore into journalissuearticles values(QSBF);.Thereafter, these fillets were storage in the refrigerator at insert ignore into journalissuearticles values(4±1°C); for 12 days. Analyzes were performed on days 0, 3, 9, and 12 during storage to detect chemical and microbial changes in both groups . The film thickness was 0.195 ± 0.010 mm, and the light transmittance values were between 10–37%. At the end of storage, the highest values of chemical analysis were found in the control group 20.35±0.49 mg/100g in insert ignore into journalissuearticles values(TVB-N);, 3.87±0.10 µmol MA/kg in insert ignore into journalissuearticles values(TBARS); and 6.27±0.00 in insert ignore into journalissuearticles values(pH);, respectively. The highest values of microbial analysis were found in the control group 5.35±0.22 log cfu/g in insert ignore into journalissuearticles values(TAMB);, 3.32±0.48 log cfu/g in insert ignore into journalissuearticles values(LAB);, Pseudomonas 5.72±0.28 log cfu/g and Enterobacteriaceae 4.38±0.68 log cfu/g in the control group respectively, although insert ignore into journalissuearticles values(TPC); was found 6.84±0.11 log cfu/g in the QSBF group. The results of chemical and microbial analysis showed that statistical difference between control and treatment groups was significant insert ignore into journalissuearticles values(p<0.05);. Quinoa starch-based biofilms insert ignore into journalissuearticles values(QSBF); had a chemically and microbiologically protective effect on trout fillets that were stored. Further studies are needed to optimize the use of insert ignore into journalissuearticles values(QSBF); as microbiological and chemical barriers for fish fillet packaging.
