Study on the Preparation and Application of Myrciaria cauliflora Extract/Chitosan Composite Films
Polyphenols were extracted from the peel of Myrciaria cauliflora by supercritical fluid extraction.Chitosan composite films with different mass fractions of Myrciaria cauliflora extract were prepared by solution blending method,and the IR spectrum,transmittance,solubility,thickness and antioxidant activity were tested.Finally,the composite films were applied to the preservation of cherry tomatoes,and the quality changes of cherry tomatoes during storage were detected by weight loss rate.The results showed that the composite films were feasible in the preservation of cherry tomatoes,and this work also provided a reference for the development and application of Myrciaria cauliflora extract and chitosan composite films.
