摘要
为探究可溶性气体稳定化(soluble gas stabilization,SGS)结合气调包装(modified atmosphere packaging,MAP)技术对冰鲜鸡块的抑菌保鲜作用,选择SGS处理时间(1、3、5、7 h)作为研究变量,将冰鲜鸡块分为1个对照组和4个处理组,对照组仅进行MAP(70%CO_(2)+30%N_(2))处理,随后置于4℃条件下贮藏。贮藏期间,测定样品包装塌陷程度、包装内CO_(2)含量、样品微生物数量、pH值、色差及水分含量的变化。结果表明:与仅进行MAP处理的对照组相比,3~7 h的SGS处理可使冰鲜鸡块的货架期延长1 d。1~7 h的SGS处理能显著提高冰鲜鸡块贮藏期间气调包装内的CO_(2)含量及样品亮度值(P<0.05),但对样品的pH值、红度值、黄度值均无显著影响。包装塌陷程度随SGS处理时间的延长而显著降低(P<0.05),且将SGS处理时间控制在5 h以内对样品的水分含量无显著影响。整体来看,在MAP前进行SGS处理可以将冰鲜鸡块的货架期有效延长1 d,且对其理化特性及感官品质无显著影响,是一种切实有效的保鲜预处理方式。
To explore the feasibility of bacteriostasis and preservation of chilled chicken cuts after soluble gas stabilization(SGS)combined with modified atmosphere packaging(MAP)technology,SGS treatment time(1,3,5,and 7 h)was selected as the research variable.The chilled chicken cuts were divided into control group(Con)and four treatment groups(S1+M,S3+M,S5+M,S7+M).The Con group only applied MAP(70%CO_(2)+30%N_(2))treatment,and then stored at 4℃.During storage,multiple indicators such as the degree of packaging collapse,the CO_(2) content in the sample packaging,the total viable count(TVC)in the meat samples,pH value,color,and moisture content were measured.The experimental results showed that compared with the Con group that only applied MAP treatment,3-7 h of SGS treatment extended the shelf life of chilled chicken cuts by 1 d.SGS treatment of 1-7 h increased significantly the CO_(2) content in the MAP and the brightness value of the samples during the storage period of chilled chicken cuts(P<0.05).But it had no significant effect on the pH value,redness value,and yellowness value of the meat samples.The degree of packaging collapse significantly dropped with the extension of SGS treatment time(P<0.05),and when the SGS treatment time was controlled within 5 h,it did not have a significant effect on the moisture content of the samples.In other words,performing SGS treatment before MAP treatment can effectively extend the shelf life of chilled chicken cuts by 1 d,and it does not have a significant impact on its physicochemical quality and sensory quality,which is a practical and effective preservation pretreatment method.
