Abstract:

Chitosan coating technology was used to preserve purple eggplant in this study. With weight loss rate and reducing sugar content as analysis indexes, orthogonal tests were conducted to optimize the formula of chitosan coating. The results showed that the optimal formula is as follows: chitosan concentration 1.5%, acetic acid concentration 10%, Tween-20 concentration 0.03 % and 1, 2 - propylene glycol concentration 3%.

Key words: chitosan, purple eggplant, orthogonal test, preservation
