| Abstract: | Objective] The research aimed to study the effects of modified konjac glucomannan film on free-keeping of fruits and vegetables.Method] The fresh-keeping effects of A.chinensis,V.labruscana Kyoho and L.esculentum Mill coated with gallic acid-modified konjac glucomannan(KGM) was carried out.Result] The results showed that the modified KGM coating treatment could effectively restrain respiration intensity,decrease weight loss and improve good fruit rate of fruits and vegetables.And the fresh-keeping effects increased with an increase in esterified degree of the modified KGM.Conclusion] The study can provide reference for applying a new type of film in fresh-keeping of fruits and vegetables. |
