FIELD: food industry.
SUBSTANCE: Bifidobacterium adolescentis strain MC 42 is activated on sterile physiological solution NaCl at 38°C during 18 hours. CFU in activated biomass makes 2.3*108 CFU/g. After that it is used for inoculation of sterilised defatted milk where natural mixture of oligofructose and inuline Beneo™ Synergy 1 (BS1) is used as bifidobacterium growth promotant and added in quantity 3 g/l. Mentioned sample B.adolescentis MC 42 fermentation is performed during 12 hours at 38°C, bifidobacterium quantity makes 2.8x109 CFU/g.
EFFECT: invention provides reduced cultivation process duration time and bifidobacterium increased quality.
