冷藏-冷冻流通环境下时间温度指示器制备与应用
Preparation and Application of Time Temperature Indicator in Refrigerated-Frozen Circulation Environment
摘要
Abstract
In order to effectively break through the problem of single temperature monitoring interval on traditional time temperature indicator(TTI),realize the visualization monitoring of the pork quality under the environment of room temperature(10℃＜C1 ≤25℃)-refrigerated(0℃＜C,≤ 10℃)-frozen(-18℃＜C1 ≤0℃),the concentration ratios of xylose,glycine and dipotassium hydrogen phosphate(K2 HPO4)were adjusted through the single-factor and orthogonal tests to prepare the time-temperature indicator suitable for different temperature intervals,to investigate the variation rules of the color and absorbance of the TTI,analyze the intrinsic mechanism of the TTI by using the Fourier infrared spectroscopy and the UV-visible absorption spectroscopy,and construct the kinetic equation to validate the matching degree of the TTI under the conditions of constant temperature and chain breakage.The results showed that the color change of TTI was more uniform and the absorbance was higher when the concentrations of xylose,glycine,and K2HPO4 were 1.00 mol/L,2.00 mol/L and 1.00 mol/L,respectively;with the increase of the storage time of TTI,the overall trend of spectrum change was not readily apparent,and there was good interaction between solutions;the activation energy of TTI was obtained from the Arrhenius equation to be 79.44 kJ/mol,and the activation energy of each quality index of pork under refrigerated or frozen constant temperature circulation environment was close to that of TTI,which indicated that TTI could monitor the quality change of pork well;the results of chain-breaking simulation showed that the quality change of pork was consistent with the color change of TTI,and the equivalent temperature differences between TTI and pork indicators were all within 1.72℃ under different temperature fluctuation tests,and the prediction error of shelf-life endpoints for both was 2.3％,which indicated that TTI could still monitor the pork quality well under temperature fluctuations.The results of the study can provide effective monitoring for the quality changes of pork in the refrigerated-frozen circulation environment and realize the temperature-quality monitoring of the whole process of cold chain logistics.关键词
