Effects of Organic Acids on Storage Quality of Mutton
[Objective] To discuss the effects of organic acid treatment on the storage quality index of mutton under 0 ～ 4℃.[Method] Samples were treated with acetic acids,lactic acid,citric acid,and then kept under 0 ～4℃.The pH value,color index,juice loss rate and the aerobic plate count were tested at different storage time and compared with blank control treatment.[Result] 2％ acetic acid,2％ lactic acid and 2％ citric acid treatments could inhibit the miscellaneous bacteria reproduction effectively and kept the lower level of pH,but cause the rising of juice loss rate.The results also showed that there were less influence about L * value and a * value between treatment and control group,but the b * value of treatment group was higher than control.[Conclusion] Acetic acid,lactic acid and citric acid treatment could effectively prolong the shelf life of mutton.
