Abstract
Abstract Microbial (psychrotrophic, mesophilic aerobic bacteria and Enterobacteriacae counts), and chemical analysis [pH, total volatile bases nitrogen (TVB-N), lipid oxidation (Thiobarbituric acid reactive substance, TBARS)] of rainbow trout ( Oncorynchus mykiss ) fillets in air (control), vacuum and modified atmosphere packaging (MAP) with various gas mixtures conditions at 4±1 °C were determined. The gas mixtures evaluated were 100% CO 2 , 2.5% O 2 +7.5% N 2 +90% CO 2 and 30% O 2 +30% N 2 +40% CO 2 . Psychrotrophic bacteria count was above 1×10 7 cfu/g on the 12th day in 100% CO 2 . However; mesophilic bacteria count was below 1×10 6 cfu/g at the end of the 1...
