摘  要:
通过研究冷鲜猪肉在不同贮存条件下感官、理化、微生物指标的变化规律,揭示冷鲜肉在不同温度和时间下肉质的变化规律,为其货架寿命和保质期提供一定参考。试验将冷鲜猪肉在4℃和~18℃条件下,分别放置1d、2d、4d、7d、10d、13d、17d、23d、30d,在设定贮存时间分别进行感官检验、pH值、挥发性盐基氮值、细菌总数、大肠菌群及霉菌和酵母菌数检测。结果表明:在4℃条件下,随时间延长,猪肉感官变差;pH由6.22升高到10d时6.72、挥发性盐基氮值由1d时的7.0mg/100g升高到10d时26.5mg/100g;微生物指标到13d时均多不可计。在-18℃下情况下,感官、理化、微生物指标等随时间的变化不明显。证明冷鲜肉的品质与温度和贮存时间存在一定相关性。

摘  要:
This study was conducted on sensory evaluation index,physicochemical index,microbial index of chilled pork at different storage condition.Chilled pork was stored at the temperature of 4°C and-18°C and stored 1,2,4,7,10,13,17,23 and 30days,then test the sensory evaluation index,ph,TVBN,total colonies of microbe,the coliform group,moulds and yeasts.The result showed that: at the temperature of 4°C,the sensory evaluation index began to deteriorate,the PH increased from6.22 to 6.72 and the TVBN increased from7.0mg/100g to 26.5mg/100g at the 10th day.But the sensoty evalution index,ph,TVBN,total colonies of microbe,the coliform group,moulds and yeasts had little change at the temperature of-18°C with the time.This proves that the quality of chilled pork is related to the temperature and time.
