γ环糊精金属有机骨架包埋姜黄素指示标签用于青虾的新鲜度监测
Indicators of γ-cyclodextrin metal-organic frameworks encapsulated with curcumin for monitoring freshness of freshwater shrimp
摘要
Abstract
To improve the stability of curcumin(Cur)indicator labels,sodium carboxymethyl cellulose and polyvinyl alcohol were used-as film forming substrates and γ-cyclodextrin metal-organic frameworks(γ-CD-MOF)encapsulated curcumin was used as an indicator to prepare smart indicator labels with different concentrations.The morphology,thermal stability and mechanical properties of smart labels were characterized and analyzed.Results showed that when the addition amount of γ-CD-MOF/Cur was 4％,the surface of the intelligent indicator label was relatively uniform,the thermal stability was good,the tensile strength was 19.12 MPa,and the elongation at break was 26.95％.In the monitoring of freshwater shrimp deterioration TVB-N increased from 1.95 mg/100 g to 29.3 mg/100 g,the smart label changed from yellow to red,and the response effect was good.This study provides a reference for the real-time freshness indicator of fresh-water shrimp.关键词
