基于紫甘蓝花青素的虾新鲜度指示膜的制备及应用
Preparation and application for monitoring shrimp freshness of indicator films based on purple cabbage anthocyanin
摘要
Abstract
In this study,the indicator films with microcrystalline cellulose/potato starch matrix and indicator(purple cabbage antho-cyanin,PC A)were synthesized and characterized.The effects of different PCA contents on the microstructure,physical properties,me-chanical properties,pH sensitivity,and environmental stability of the indicator film were analyzed.Results showed that structure of the in-dicator film containing 6 g/L PCAs were uniform and the comprehensive properties of the indicator film was improved with water absorption rate(147.92％),the water solubility(25.72％),the water vapor permeability[1.59 × 10-10 g·m/(m2·Pa·s)],the tensile strength(18.43 MPa),the elongation at break(5.59),excellent environmental stability and high pH sensitivity.When it was used in monitoring shrimp freshness,the total volatile basic nitr value and pH value of shrimp increased from 5.97 mg/100 g to 44.38 mg/100 g and 6.77 to 7.68 at 8 days at 4 ℃,respectively.Meanwhile,the film changed from red to gray pink,and the color change was visible.This research can provide reference to develop freshness indicator film for aquatic products.关键词
