Abstract

The invention relates to a production method for fermented milk through symbiosis of bifidobacterium and yeast. The method utilizes the symbiotic relationship between bifidobacterium and yeast and allows bifidobacterium and yeast to ferment in milk together so as to produce the symbiotic fermented milk. The fermentated milk has pure flavor of lactic acid and aroma of yeast, can supplement beneficial substances like proteins and probiotics and complement a great amount of vitamin B1 and B2 produced in yeast fermentation at the same time and is functional food with good taste and rich nutrients.

Description

technical field [0001] The invention provides a production method and raw material ratio of bifidobacterium-saccharomyces symbiotic fermented milk, belonging to the field of food fermentation. Background technique [0002] [Bifidobacteria can produce lactic acid and acetic acid after fermentation in the human intestine, which can improve the utilization rate of calcium, phosphorus and iron, and promote the absorption of iron and vitamin D. Bifidobacteria ferment lactose to produce galactose, which is a component of cerebrosides in the brain nervous system, and is closely related to the rapid growth of the baby's brain after birth. Bifidobacteria can produce vitamin B 1 , B 2 , B 6 , B 12 And alanine, valine, aspartic acid and threonine and other essential nutrients for the human body have important nutritional effects that cannot be ignored. [0003] Bifidobacterium also has an anti-aging effect. Microecological surveys in Europe, America and Japan have shown that the n...
