中文摘要:

为控制鲍鱼微波冻干过程中微生物数量,试验过程中将鲍鱼进行纳米银涂膜。实验结果表明,在微波冻干过程中,以0.3 mg/L的纳米银淀粉液涂膜,鲍鱼中细菌总数下降99.2%,大肠菌群MPN值小于30。微波和纳米银涂膜结合,很好的控制了冻干鲍鱼的微生物,而且纳米银涂膜对鲍鱼的干燥效率无明显影响。

英文摘要:

The aim of this study is to develop a method on the process of microwave freeze drying abalone,nano-silver coating was introduced and the technique experiments were carried out.The results was showed that nano-silver of 0.3mg/L coating could sterilize about 99.1% and the count is less than 30 of Coliform bacteria on the process of microwave freeze drying.To ensure perfect sterilization effect,nano-silver coating technique was combined with microwave freeze drying process.Nano-silver coating treatment could lead to low microorganism number and had no significant effect on drying efficiency.
