‘章姬’和‘红颜’草莓采后微生物安全评价及品质劣变研究
Microbial safety evaluation and quality deterioration of'Zhangji'and'Hongyan'strawberries during storage
摘要
Abstract
Taking'Zhangji'and'Hongyan'strawberries as materials,the changes of total colony count,enumeration of coliforms,mold and yeast of the 2 strawberry varieties stored at (20 ± 0.5) ℃ or (4 ± 0.5) ℃,RH 80％-90％ for 6 days were studied.And combined with the quality parameters such as decay rate,soluble solids content,hardness and tightness,the microbial safety and food risk of strawberry were evaluated.The results showed that although'Zhangji'and'Hongyan'strawberries could better maintain the appearance quality and taste for 3 days after harvest,even for 6 days at low temperatures,but the total number of colony,enumeration of mold and yeast of the 2 strawberry varieties increased to more than 10 times that of the day of picking at the second and third day at 20 ℃,and at the third and fourth day at 4 ℃ respectively.The coliforms enumeration of 'Hongyan'stored at 20 ℃ increased higher than 200 MPN/g after 5 days.Therefore,the increase of the risk of microbial contamination was prior to the deterioration of appearance quality and taste,and there was a risk of microbial food safety.关键词
