微冻贮藏中温度波动对猪肉品质的作用机理研究
Mechanism of temperature fluctuation on pork quality during superchilling storage
摘要
Abstract
To determine the acceptable level of superchilling temperature fluctuations to effectively maintain the quality of fresh pork,different temperature fluctuations[-3 ℃,(-3±2)℃,(-3±4)℃]were set for pork storage.Changes of pork quality were meas-ured and the mechanisms of temperature fluctuations on the quality of superchilled pork were explored from the perspectives of moisture distribution,microstructure,and oxidation.The results showed that compared to the control group,the a*value of the low fluctuation group was reduced,and the vacuum storage loss and cooking loss were significantly increased(P＜0.05).No significant changes in pH value and shear force value were observed(P＞0.05).However,the color of the high fluctuation group further deteriorated,and the pH value and shear force value significantly increased(P＜0.05).In addition,temperature fluctuations led to a decrease in the content of im-mobilized water and an increase in the content of free water(P＜0.05),thus resulting in the decrease of pork water-holding capacity.Be-sides,temperature fluctuations could affect the microstructure of muscle tissue.Furthermore,total sulfhydryl content decreased and thio-barbituric acid reactive substances increased after temperature fluctuations treatments(P＜0.05).To conclude,temperature fluctuations could cause the quality deterioration of superchilled pork and decreasing temperature fluctuations could inhibit the deterioration of pork.This article can provide theoretical basis for the application of superchilling storage technology in the meat industry and the improvement of fresh meat quality.关键词
