Chitosan is soluble in acid and edible coating substance that applied in the preservation<br />

of fresh fruit, vegetable or other fresh-cut material. The main objective of this study<br />

was to extend the shelf life of cauliflower using different concentration of chitosan<br />

ranging from 0.01%, 0.02%, 0.03% and 0.04% and control with no chitosan coating.<br />

The effect of chitosan coating was investigated in aspect of weight loss, color,<br />

firmness, black spot disease and ascorbic acid. There was no significant different on<br />

colour, firmness and weight loss across all treatments for chitosan coating on<br />

cauliflower. However, cauliflower coated with 0.02% of chitosan significantly reduce<br />

the appearance of black spot at day 4 and lower the ascorbic acid at day 3. As a<br />

conclusion chitosan coating could not prolong the shelf life of fresh cut cauliflower,<br />

hence this study could not be applied for postharvest storage technique.<br />
