Effects of chitosan and ascorbic acid coating on the chilled tilapia fish (Oreochromis niloticus) fillet

The effect of chitosan-based coating containing ascorbic acid (AA) for shelf-life extension of chilled (4 °C) tilapia fish fillet was evaluated over a 15-day duration of storage. A 3 X 3 Factorial Design comprising three concentrations of ascorbic acid (0, 2.5 and 5% w/v) and three concentrations of...

A 3 X 3 Factorial Design comprising three concentrations of ascorbic acid (0, 2.5 and 5% w/v) and three concentrations of chitosan (1, 1.5 and 2% w/v) were used.
