METHOD FOR PRODUCTION OF DRY SYNBIOTIC CONCENTRATE BASED ON MILK WHEY Russian patent published in 2012 - IPC A23C21/02 A23C21/08 

FIELD: food industry.

SUBSTANCE: invention relates to dairy industry. The dry symbiotic concentrate production method envisages introduction of a defatted or soya bean milk hydrolysate in an amount of 2.5-10% into purified milk whey, the mixture heating, an alkaline catalyst introduction into the mixture till the medium pH is equal to 11.0±0.5 units, pasteurisation, lactose isomerisation into lactulose at a temperature of 70-85°C and under thermostatic control during 15-30 minutes, the isomerised whey neutralisation with a citric acid solution till pH is equal to 6.5±0.2 units, condensation till dry substances weight fraction is equal to 20-25%, cooling till fermentation temperature equal to 37±1°C, a bifidobacteria starter introduction in an amount of 5-10% of the volume of whey enriched with lactulose and defatted or soya bean milk hydrolysate, ripening at a temperature of 37±1°C during 24-36 hours and drying in a spray drier.

EFFECT: invention allows to increase bifidobacteria quantity in the ready product and enhance the latter biological value due to reduction of duration of undesirable heat impact on the starter microflora.
