Probiotics-containing infant formula, and preparation method and storage method thereof

Abstract

The invention discloses a probiotics-containing infant formula, and a preparation method and a storage method thereof. The probiotics-containing infant formula is prepared from the following raw materials: 15 to 35 percent of raw milk, 5 to 10 percent of lactose, 5 to 15 percent of demineralized whey powder, 5 to 15 percent of whey protein concentrate, 5 to 20 percent of structural grease, 1 to 6 percent of probiotics, 0.01 to 0.1 percent of infant vitamin premix, 0.01 to 0.1 percent of infant mineral premix, and activated probiotics freeze-dried powder; the probiotics adding amount in the activated probiotics freeze-dried powder is 1*10<7>-1*10<8>cfu / g; the percentage is mass percentage of each component in the infant formula; the moisture content of the infant formula is 1.8 to 3.7 percent and water activity aw is 0.15-0.3. The viable count of the probiotics contained in the infant formula is stable, and after the infant formula is stored at normal temperature for six months, the viable count of the probiotics contained in the infant formula is more than 10<8>cfu / g.

Description

technical field

[0001] The invention belongs to the field of food, and in particular relates to an infant formula milk powder containing probiotics, a preparation method and a storage method thereof. Background technique

[0002] Infant formula milk powder is recommended as an important supplementary food for the growth and development of non-breastfeeding and post-weaning infants based on its scientifically reasonable breast milk formula. Utilizing the ever-developing knowledge of physiology, the science of microecology has continuously improved the quality of formula milk powder, making it closer to the functions of breast milk. Breast milk contains natural probiotic factors and active immune substances, which can promote the growth of beneficial intestinal flora of newborn infants, inhibit spoilage bacteria, and enhance immune function. Adding high-quality probiotics to infant formula milk powder will directly supplement the beneficial bacteria in infants and young child...
