Milk powder capable of improving infant's immunity and production method thereof

Abstract

The invention relates to a milk powder capable of improving the infant's immunity. The milk powder is composed of the following raw materials in parts by weight: 600 to 800 parts of high-oil desalted whey powder, 100 to 200 parts of whole milk powder, 3 to 5 parts of hydrolyzed whey protein powder, 1 to 3 parts of whey protein powder, 2 to 5 parts of galactooligosaccharide, 1 to 3 parts of fructo-oligosaccharide, 1 to 3 part of docosahexaenoic acid (DHA), 1 to 3 parts of eicosatetraenoic acid (ETA) 0.4 to 1 part of lactoferrin, 0.05 to 0.07 part of bifidobacterium, 3 to 6 parts of multi-vitamins, and 2 to 7 parts of composite mineral substances. The milk powder can provide enough nutrients for the growth of infants, can be easily absorbed by the infants, and is capable of improving the infant's immunity and reducing the phenomenon of excessive internal heat, diarrhea, or constipation caused by dyspepsia. The milk powder is produced through a dry-mixing technology, thus the loss of active substances (EHA, ETA, etc.) during the process of wet process addition is avoided, and the activity loss of lactoferrin and bifidobacterium in the wet process addition is maximally reduced.

Description

technical field [0001] The invention belongs to the field of dairy processing, and in particular relates to a milk powder for improving the resistance of infants and a production method thereof. Background technique [0002] At present, the overall level of breastfeeding in my country is relatively low. According to data recently released by the Health and Family Planning Commission, the exclusive breastfeeding rate for children aged 0-6 years in my country is 27.8%, which is far lower than the 50% feeding rate determined in the "China Child Development Program". , and the carbohydrates in breast milk are very peculiar. A considerable part of the carbohydrates in breast milk do not provide energy for the human body, but oligosaccharides that exist as biologically active oligosaccharides, which can promote local immunity in the intestinal tract and development of systemic immunity. The healthy intestinal environment established by breast milk is far inferior to that of formula...

Problems solved by technology

[0003] In order to make milk powder close to breast milk, functional activating substances, lactoferrin, probiotics and other ingredients are added to milk powder on the market, but the addition method is often wet method, and most of these active substances are heat-sensitive or limited in use It is not suitable for wet addition, such as docosahexaenoic acid and eicosatetraenoic acid are easily oxidized and deteriorated in direct contact with air and moisture, while docosahexaenoic acid and eicosatetraenoic acid are used in industry The acid powder has been microencapsulated and embedded. If it is added by wet method, the embedded layer will be destroyed and cause loss.

However, the activity of lactoferrin, probiotics and other ingredients after wet sterilization is greatly lost or even loses their activity.
