Formula milk powder for pregnant and lying-in women and preparation method thereof

Abstract

The invention discloses a formula milk powder for pregnant and lying-in women and a preparation method thereof. The formula milk powder comprises: 30%-55% of skimmed milk powder, 30%-55% of whole milkpowder, 1%-8% of inulin, 1%-8% of galactooligosaccharide, 1%-6% of hydrolyzed whey protein powder, 0.2%-1.2% of calcium carbonate, 0.1%-1.1% of docosahexaenoic acid grease, 0.1%-1% of lactose, 0.1%-0.8% of minerals, 0.1%-0.7% of vitamins and 0.02% of bifidobacterium lactis HN019 freeze-dried powder. According to the formula milk powder, the inulin and the galactooligosaccharide serve as strengthening factors of the Bifidobacterium lactis HN019, the concentration of the Bifidobacterium lactis in excrement of pregnant women is increased, constipation is prevented or relieved, intestinal peristalsis is stimulated, excrement wettability is improved, intestinal flora balance and intestinal health are maintained, and absorption of vitamin B1, zinc and other microelements by pregnant and lying-in women is improved. Experimental results show that after the milk powder is eaten, the concentration of Bifidobacteria in the excrement of the pregnant women reaches 10<10> cfu/g or above, and the concentration of the Bifidobacteria in intestinal tracts is obviously increased. The formula and the process of the milk powder can also effectively improve the problem of wall adhesion in a spray drying stage.

Description

technical field [0001] The invention relates to the technical field of dairy products, in particular to formula milk powder for pregnant women and a preparation method thereof. Background technique [0002] Maternal milk powder is developed according to the nutrients required by mothers and babies during pregnancy. It is rich in various nutrients and can provide adequate nutrition for expectant mothers and fetuses. Pregnant women who take this type of milk powder can avoid malnutrition for themselves and their fetuses, and promote their own health and the normal development of their fetuses. Due to physical changes during pregnancy, women often have intestinal problems such as constipation and flatulence. Currently, milk powder for pregnant women on the market mainly adds corresponding nutrients according to the nutritional needs of pregnant women, and seldom improves intestinal flora and promotes digestion and absorption. And other aspects to effectively solve the troubles...

AI Technical Summary

Problems solved by technology

[0003] Spray drying is usually used in the process of milk powder processing, and the wall sticking phenomenon is a common and difficult problem in the spray drying process. The wall sticking phenomenon not only causes the loss of materials and reduces the product quality, but also leads to the termination of the spray drying process or even production accident

Judging from the current research on the problem of sticking to the wall, most domestic and foreign scholars solve the problem of material sticking to the wall from the hardware aspects such as the atomization angle of the dryer and the roughness of the inner wall. However, the parameters of the dryer are usually determined by the manufacturer and are not easy to change. At present, few people solve the sticking problem from the perspective of materials
