Problems solved by technology

[0006] The publication number is CN101233873A, and the title of the invention is a kind of fat used in the patent of liquid milk for infants from newborn to 6 months. The fat used in the patent is vegetable oil. In this traditional fat, palmitic acid is located at the Sn-1 and Sn-3 positions. After hydrolysis by lipase, free palmitic acid will be generated, which will combine with calcium, magnesium and other elements to form calcium soap and other compounds, resulting in the double loss of palmitic acid and calcium in the body, which is not conducive to the absorption of fat and calcium by the baby, and may easily cause constipation and diarrhea in the baby. stomach ache

Embodiment 1

[0040] Embodiment 1 A kind of preparation that is applicable to the liquid milk of newborn baby to 6 months old

[0041] Taking the production of 1000L liquid milk as an example, the flow chart is as follows figure 1 As shown, the specific steps are:

[0042] (1) Acceptance of fresh milk: select qualified fresh milk as raw milk, strictly control substances harmful to human body in raw milk, physical and chemical indicators, sensory indicators, and microbial indicators must meet the requirements of national standards;

[0043] (2) Raw milk pretreatment: filter and purify the raw milk, and then centrifuge the milk to remove impurities;

[0044] (3) Pasteurization: the raw materials pretreated in step (2) are sterilized at 62°C for 30 minutes;

[0045] (4) Adding ingredients: add whey protein concentrate, lactose, nucleotides, taurine, choline, docosahexaenoic acid (DHA), and arachidonic acid (ARA) to sterilized fresh milk , soybean lecithin, complex vitamins, complex trace el...

Embodiment 2

[0057] Embodiment 2 A kind of preparation that is suitable for the liquid milk of newborn baby to 6 months old

[0058] Taking the production of 1000L liquid milk as an example, the specific steps are as follows:

[0059] (1) Acceptance of fresh milk: select qualified fresh milk as raw milk, strictly control substances harmful to human body in raw milk, physical and chemical indicators, sensory indicators, and microbial indicators must meet the requirements of national standards;

[0060] (2) Raw milk pretreatment: filter and purify the raw milk, and then centrifuge the milk to remove impurities;

[0061] (3) Pasteurization: the raw materials pretreated in step (2) are sterilized at 62°C for 30 minutes;

[0062] (4) Adding ingredients: add whey protein concentrate, lactose, nucleotides, taurine, choline, docosahexaenoic acid (DHA), and arachidonic acid (ARA) to sterilized fresh milk , soybean lecithin, complex vitamins, complex trace elements, 1,3-dioleic acid-2-palmitic aci...

Embodiment 3

[0074] Embodiment 3 Stability of liquid milk of the present invention and its influence on infant digestion and absorption

[0075] 1. Stability

[0076] In the invention, the 1,3-dioleic acid-2-palmitic acid structural oil is embedded in the microcapsule technology and added to the infant liquid milk, which improves the oxidation stability of the infant liquid milk, prolongs the shelf life, and is beneficial to industrial production. Compared with traditional baby liquid milk, the shelf life of baby liquid milk produced by this technology is at least extended from 86 days to 255 days.

[0077] figure 2 For carrying out Schaal oven accelerated oxidation experiment to two kinds of infant liquid milks, measure the result that its peroxidation value draws, compare and draw the infant liquid milk of the present invention during storage period peroxide value change tendency and the peroxide value of traditional infant liquid milk The trend of change is gentle, and the liquid mil...

Abstract

The invention discloses liquid milk applicable to a baby from newborn to six months and a preparation method thereof, and belongs to the field of processing and manufacturing dairy products. The novel liquid milk applicable to the baby from newborn to six months is prepared from fresh cow milk, concentrated whey protein, lactose, nucleotide, taurine, choline, docosahexaenoic acid (DHA), arachidonic acid (ARA), soyabean lecithin, complex vitamins, complex trace elements, 1,3-dioleic acid-2-palmitic acid structure oil microcapsules which are taken as raw materials, and taking component ratios in breast milk as principles. The addition of the structure oil microcapsules improves the content of Sn-2-palmitic acid in the liquid milk, so that not only can a fatty acid structure in the baby liquid milk be closer to human milk and the absorption of fatty acid and calcium by the baby be enhanced, but also the contact between structure oil and air is inhibited, the oxidation and the rancidity of the structure oil are avoided, the oxidation stability of the baby liquid milk is improved, and further the shelf life of the baby liquid milk is prolonged.

Description

technical field [0001] The invention relates to an infant liquid milk and a preparation method thereof, in particular to a new type of infant liquid milk suitable for newborn to 6 months and a preparation method thereof, belonging to the field of dairy product processing and manufacturing. Background technique [0002] Human milk is the most perfect food for infants, containing 3% to 5% of fat. As an important ingredient in human milk, it provides 50% to 60% of energy for growing infants, and also provides essential fatty acids for infants. , triglycerides account for more than 98% of these fats. However, for a variety of reasons, breastfeeding is gradually failing to meet the growth and development needs of infants, and it is becoming more and more important to supplement infants with baby food. In traditional infant formula, the presence and distribution of fatty acids are very different from human milk. This difference not only leads to a decrease in the utilization effi...
