基于阿魏酸和花青素共色作用的结冷胶/明胶薄膜用于鸡肉新鲜度监测
Gellan Gum/Gelatin Composite Film Based on the Copigmentation Effect of Ferulic Acid on Anthocyanins for Freshness Monitoring of Chicken Meat
摘要
Abstract
To enhance the sensitivity of anthocyanin-based films for monitoring chicken freshness,an FA-BWA complex was prepared based on the copigmentation effect of ferulic acid(FA)on black wolfberry anthocyanins(BWA),and its pH responsiveness was determined.Using gelatin and gellan gum(GG)as substrates,GG-FA-BWA films were fabricated,characterized for their microstructure,intermolecular interactions and mechanical properties,and finally applied to monitor chicken freshness.Results showed that BWA solution,FA-BWA solution,GG-BWA film,and three GG-FA-BWA films(with FA/BWA ratios of 1:1,1:2 and 1:4(m/m),named as GG-FA-BWA1,GG-FA-BWA2 and GG-FA-BWA4,respectively)exhibited good pH responsiveness.The addition of BWA and FA-BWA complex significantly increased the surface roughness and redness value while decreasing the brightness value,yellowness value,color difference(ΔE),and thickness of the films(P<0.05).Fourier transform infrared(FTIR)spectroscopy results revealed that the film components were connected by hydrogen bonding,resulting in a compact,ordered structure.The addition of FA-BWA complex significantly reduced the moisture content and light transmittance while increasing the elongation at break of the films(P<0.05).The ΔE of the GG-FA-BWA films showed high correlation with freshness indicators of chicken meat(R2>0.95),and the GG-FA-BWA4 film showed optimal monitoring performance.This study provides a reference for developing more sensitive films for monitoring the freshness of chicken meat.关键词
