摘要: 本研究在食品基质(奶油)中,从14个乳酸菌种(株)中筛选出胆固醇同化率为40%以上的菌种(株)9个,其中胆固醇同化率为45%以上的3个;它们均可用于低胆固醇发酵食品的生产中。试验还表明乳酸菌降低胆固醇的作用主要是它的胆固醇同化作用,而与胆固醇的共沉淀作用不明显。

关键词: 乳酸菌, 胆固醇, 奶油, 同化作用

Abstract: Nine lactic acid bacteria(LAB) species (strains) which can assimilate 40% cholesterol from food (butter) culture media are screened from 14 species(strains), in which 3 species(strains) can assimilate 45% cholesterol. They could be applied to the production of fermented low - cholesterol food. The result shows that the ability of LAB to remove cholesterol from food media may be due to the assilimation of cholestero, white the coprecipition with cholesterol is not significant.

Key words: Lactic acid bacteria Cholesterol Butter Assilimation.
