超高压处理对软包装太湖银鱼灭菌效果及品质的影响

研究了软包装太湖银鱼常温超高压处理后的微生物存活量与不同压强、保压时间的关系，以及超高压处理对太湖银鱼水分含量、可溶性蛋白质和游离氨基酸质量分数的影响。结果表明：600 MPa高压处理能杀灭银鱼中所有致病菌，使其菌落总数降到100 cfu/g以下；高压会造成银鱼水分、可溶性蛋白质和游离氨基酸的损失，但损失量较小。
This paper studied the relationship between the microflora of Tai Lake whitebait with flexible package and the HHP parameters. The influence of HHP process on the moisture，soluble protein and free amino acid contents of whitebait was also investigated. Results showed that：the 600MPa HHP treatment could kill pathogenic bacteria in all species and decrease the total number of microflora to less than 100cfu/g； HHP process led to slight losses of the moisture，soluble protein and free amino acids of whitebait
