Abstract:
Using quaternary ammonium salt of chitosan as coating material，the rate of weightlessness and the content of soluble solid as evaluative standards，the experiments studied the effects of concentration，pH value and soaking time on the preservation effects of quaternary ammonium salt of chitosan on cucumbers.The results showed that the making film solution were 1.0 % and pH value varied from 5.0 to 5.5 for cucumbers.After 15 days，the rate of weightlessness of cucumbers were 5.6%，and the content of the soluble solid were 3.1%.The film could effectively maintain the cucumber sensory quality，reduce weightlessness lose，and could also inhibit the loss of soluble solid content，extend the goods shelves time in the room temperature store.
