真空包装冷却羊肉pH值和颜色的近红外快速无损检测
Rapid and Nondestructive Detection of the pH Value and Luminosity for Vacuum Packed Chilled Mutton by Using Near Infrared Reflectance Spectroscopy Technique
摘要
Abstract
[Objective] The purpose of this research is to solve the problems in the traditional determination of mutton freshness physicochemical indexes,such as the fussy operation,the necessary chemical reagents,and destruction and contact of samples and so on.[Method] The small tailed Han Sheep in Xinjiang was taken as the research object,and the near infrared reflectance spectroscopy (NIRS) technique was used to carry out the rapid and nondestructive detection of physicochemical indexes in vacuum packed chilled mutton during the storage.For the chemical index pH and the physical index luminosity (L*),the spectral pretreatment and the feature bands selection methods were adopted to optimize and simplify the prediction model of each index content.[Result] The optimal models of pH and L* were the multiple linear regression (MLR) models established with the feature bands,which were selected by the combination of genetic algorithm (GA) and successive projections algorithm (SPA) rather than the single method.The correlation coefficients of prediction sets were 0.91 and 0.91,and the root mean square errors of prediction sets were 0.13 and 1.91.[Conclusion] NIRS technique has the detection advantages of non-pollution,nondestructive,and simultaneous analysis of multiple indexes,and it can replace traditional detection methods to achieve rapid,nondestructive and accurate detection of freshness physicochemical indexes in meat.关键词
