草鱼内脏水解蛋白功能性质及对微生物的培养效果研究

Visceral protein functional properties of grass carp measurement and verification of effect of peptone

对制备得到三种草鱼内脏水解蛋白功能性质进行测定,并通过不同培养基培养枯草芽孢杆菌和大肠杆菌,优选出最适微生物培养基的草鱼内脏水解蛋白。结果表明：3号草鱼内脏水解蛋白的功能性质最佳,其水溶性指数、乳化性、乳化稳定性和起泡性最好,各最高值分别为：水溶性指数99.8%,乳化性73%,乳化稳定性75.9%,起泡性162.8%;最适枯草芽孢杆菌和大肠杆菌生长的内脏水解蛋白为草鱼内脏蛋白水解液经脱色脱腥处理后的3号样品。

Determine three different soluble protein samples functional properties.No.3 has best solubility,emulsifiability,emulsion stability and foamability,and the percenlages.are 99.8 %,73 %,75.9 %,162.8 %.Cultivation Bacillus subtilis and Escherichia coli with different media,the best growth of the bacteria is No.3.The sample is FVPH after deordorizing and decolorizing.
