Abstract
With fresh cut apple as the test raw material,different concentration chitosan solution was prepared with acetic acid of 1%.The fresh cut apple was preserved in 0℃ and 25℃ after daubing the fresh cut apple chitosan solution.Titratable acid,browning degrees,and loss ratio were measured in a certain interval of time.The results showed that the preservation effect was the best when chitosan concentration was 1.63% at 0℃ and 90 s.
