Název v původním jazyce

Effect of modified atmosphere packaging on the course of physical and chemical changes in chilled muscle tissue of silver carp (Hypophthalmichthys molitrix, V.)

Popis výsledku v původním jazyce

The effect of two types of modified atmosphere (MA1: 69% N2, 25% CO2, 5% O2, 1% CO? MA2: 70% N2, 30% CO2) on changes in physical and chemical parameters (pH, aw-water activity, TVBN - total volatile basic nitrogen, TMA-trimethylamine, FFA-free fatty acids, PV-peroxide value, TBA-thiobarbituric acid) in muscle tissues of the silver carp was monitored in the study. The samples were stored at temperatures +2 +- 2°C for 18 days. Changes in gas volumes (CO2 and O2) in v MAs were also monitored. CO2 levels increased in MA1 but decreased in MA2. At the end of 18 days of storage, a significantly (P{0.01) lower water activity (aw) levels were found in samples packaged under MA1, in contrast to samples packaged under MA2 where water activity values showed considerable fluctuation. Variations in pH values in the two types of MA showed similar trends. Sample pH gradually decreased until day 9 of storage. On day 11, muscle tissue pH increased markedly and then began to decrease again. The overall d
