Effect of Nano-Silver Coating on Microorganism Control of Microwave Freeze-Dried Abalone

Abstract:

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.
