Process for preparing a functional fermented milk product with low acidity and containing a low content of lactose and enhanced with galactooligosaccharides and Bifidobacterium, and functional fermented milk product prepared therewith

摘要

The present invention relates to a process for preparing a functional fermented milk product with low acidity and containing a low content of lactose and enriched with galactooligosaccharide and Bifidobacterium, and functional fermented milk product prepared therewith. The process is characterized by converting lactose in milk materials to galactooligosaccharide before subjecting the milk materials to lactic fermentation. The process is further characterized by adding fructooligosaccharide to milk materials before subjecting the milk materials to lactic fermentation; the addition of fructooligosaccharide promotes growth of Bifidobacterium during lactic fermentation and increases the amount of galactooligosaccharide in the final product.

主权项

1. A process for preparing a functional fermented milk product with low acidity and a low lactose content and enhanced with galactooligosaccharides and Bifidobacterium, comprising:
conducting an enzymatic hydrolysis reaction by directly treating milk materials with a lactase to provide enzyme-hydrolyzed milk materials; conducting a lactic fermentation reaction by treating the enzyme-hydrolyzed milk materials with Bifidobacterium to provide fermented milk materials, wherein the fermented milk materials have a pH of 4.3 to 5.5; and treating the fermented milk materials to provide a functional fermented milk product.
