A new fermented milk using capsular polysaccharide-producing Lactobacillus kefiranofaciens isolated from kefir grains

Abstract
Summary: A new fermented milk was prepared by using capsular polysaccharide-producing Lactobacillus kefiranofaciens K1 isolated from kefir grains. Fermentation was carried out at 30°C for 18 h, when pH 4·5 was attained. The product had a ropy consistency and was resistant to syneresis. However, the product was given lower scores for acceptability by a consumer panel than a similar product made with Lb. delbrueckii subsp. bulgaricus.
