一种复合型生物保鲜剂在牡蛎保鲜中的应用研究

Application of A New Compound Biopreservative in Storage of Oyster

研制一种复合型天然防腐保鲜剂,该保鲜剂在牡蛎保鲜方面有很好的作用,可以将牡蛎的货架期延长近1倍,并改变了牡蛎冷藏过程中优势腐败菌的种类。在货架期终点时,对照组的优势腐败菌为假单胞菌(Pseudomonas),比例为53%;保鲜剂组的优势菌为乳酸球菌(Lactococcus),比例为70%。

A new biopreservative was developed, which has excellent effect on extending shelf-life of oysters. The microflora of oysters treated by the biopreservative is altered during the storage at 5 ℃. At the end of shelf-life, Pseudomonas is found to be the dominant spoilage bacterium for the control samples, which accounts for was 53%; Lactococcus is the dominant bacterium for the treated samples, which accounts for 70%.
