摘要
Abstract
[ Objective ] The aim was to study the detection methods of aerobic bacterial count for high viscosity samples based on soybean dietary fiber. [ Method ] The pretreatment process and medium selection of soybean dietary fiber samples were studied. [ Result ] In the pretreatment process of soybean dietary fiber samples, the diluents taken by weighing method and RAININ Pos-D exteriorization piston trace removing liquid instrument had higher aerobic bacterial count than that taken by conventional method. Among 3 count mediums, 3M PetriflimTM had the highest aerobic bacterial count; next came plate count agar, and TIC nutrient agar medium was the worst. 3M PetriflimTM and TIC nutrient agar medium ad better precision and less personal counting deviation than plate count agar. [Conclusion] The research provides reference for detecting samples with particles,high water absorbability and high viscosity, etc.关键词
