Abstract

Abstract: The fresh-cut plum was used as material and treated with the chitosan complex film containing certain concentration of chitosan combined with vitamin C，sodium carboxymethyl cellulose(CMC—Na)and sodium alginate．The effects of
different chitosan complex film formulas selected through orthogonal experiment of L9(34)on the respiratory intensity，soluble solid content，browning degree，weight-loss ratio，firmness，titratable acid，senescence index and ratio ofcommodity in the fresh-cut plum were studied．The results showed that the chitosan complex film could maintain the quality of fresh-cut
fruit，and the optimal formula of chitosan complex film was 0．6％ chitosan，0．2％ CMC—Na and 0．4％ Vc．

Key words: chitosan complex film, pulm(Flacourtia ramontchii), fresh-cut, quality
