Fermented milk prodn. using bifido-bacteria - as mixed culture with yeasts

摘要

Prodn. of fermented milk is effected by inoculating milk with bifidobacteria and yeasts and culturing under aerobic conditions. Suitable bifidobacteria are Bifidobacterium bifidum, B. breve, B. infantis and B. longum. Suitable yeasts include Saccharomyces, Candida, Debaromyces, Hansenula, Pichia, Torulopsis and Trichosporon spp. The starting material can be whole milk, skim-milk, condensed milk or reconstituted skim-milk powder, pref. with a solids content of 3-30%. The process is simpler than prior art processes and yields a pleasant-tasting prod. with a higher bifidobacteria count and higher pH than prods. obtd. using bifidobacteria alone.
