Milk powder drunk by premature infant and preparation method of milk powder

Abstract

The invention discloses milk powder drunk by premature infant and a preparation method of the milk powder. The milk powder comprises the following components in percentage by mass: 35-50% of demineralized whey powder, 20-26% of compound fat, 5-20% of lactose, 8-12% of whey protein concentrate, 3-10% of medium chain triglyceride, 1-3% of probiotic composition, 0.7-0.9% of complex minerals, 0.3-0.4%of complex vitamins, 0.3-0.6% of docosahexaenoic acid oil, 0.3-0.6% of arochidonic acid oil, 0.03-0.1% of lactoferrin and 0.02-0.05% of nucleotide. The preparation method comprises the following steps: uniformly mixing demineralized whey powder, lactose, whey protein concentrate, probiotic composition and water until the components are completely dissolved to obtain feed liquid A; uniformly mixing compound fat and medium chain triglyceride so as to obtain feed liquid B; mixing the feed liquid B and A, and homogenizing to obtain feed liquid C; and adding the complex vitamins and compound minerals into the feed liquid C, sterilizing, concentrating and drying so as to obtain a semi-finished product E, and performing dry mixing with the docosahexaenoic acid oil, arochidonic acid oil, lactoferrin and nucleotide, thereby obtaining the milk powder.

Description

technical field [0001] The invention belongs to the field of dairy products, and in particular relates to milk powder for premature infants and a preparation method thereof. Background technique [0002] Live-born babies born before 37 full weeks of gestation are called premature babies or immature babies. Most of their birth weights are below 2500g, their head circumference is below 33cm, and their organ function and adaptability are worse than those of full-term babies. Premature infants should be given special care. Small-for-gestational-age infants (small-sized infants, immature infants) are those whose birth weight is reduced to below the 10th percentile of normal weight for the gestational age or below two standard deviations from the mean due to factors such as placental insufficiency. In medicine, those whose birth weight is less than 2500g are collectively referred to as low birth weight infants, and those whose birth weight is less than 1500g are called very low b...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to adjust and optimize the protein composition, fat composition and carbohydrate composition of the formula in view of the characteristics of immature intestinal digestive system and low utilization rate of digestion and absorption of premature infants, and add an easy-to-digest and absorb α-lactalbumin (brought in by concentrated whey protein powder), medium-chain triglycerides, and make the energy, protein, some minerals, vitamins and other indicators in the formula higher than GB 25596-2010 "National Food Safety Standard Special Requirements of the General Principles of Infant Formula Food for Medical Purposes to meet the nutritional needs of premature infants
