Children formula milk containing OPO structure fat and preparation method of children formula milk

Abstract

The invention provides children formula milk containing OPO structure fat and a preparation method of the children formula milk. The children formula milk comprises 35-50 parts of whole milk powder, 20-35 parts of skimmed milk powder, 30-45 parts of demineralized whey powder, 17.9-32.9 parts of auxiliary materials, 0.1-0.5 part of docosahexaenoic acid oil, 0.2-1.0 part of arachidonic acid oil, 0.5-2 parts of concentrated whey protein powder, 1.5-2.0 parts of a compound emulsion stabilizer, 0.1-0.5 part of sodium citrate, and 0.5-1.5 parts of dipotassium hydrogen phosphate, and further comprises 15-25 parts of 1,3-dioleoyl-2-palmitoylglycerol and 15-25 parts of refined vegetable oil, wherein the refined vegetable oil is mixed oil of one or more kinds of sunflower oil, rapeseed oil, soybean oil and palm kernel oil. In the preparation method, emulsifying agents such as mono-and diglycerides of fatty acids and phosphatide are added, and fat multistage emulsifying treatment of high-emulsifying cutting for three times, and second-class homogenizing for three times are performed, so that the average particle sizes of granules of the treated fat are 400nm-1<mu>m and extremely stable, the condition that the fat is agglomerated and floats can be effectively avoided, and the oxidization degree of the fat is reduced.

Description

Technical field [0001] The invention relates to the field of children's formula milk, in particular to a children's formula milk containing OPO structural oil suitable for drinking by children aged 3 to 6 and a preparation method. Background technique [0002] Children over 3 years old, especially young children between 3 and 6 years old, still need some nutritional factors that are different from adults in terms of nutrition, and they need to gradually transition to food for adults in terms of growth. There are many kinds of children's milk in China with different tastes, but they are basically processed by simply adding white sugar and nutrients to the milk. There is no product that is similar in nutrition to children's formula milk powder, or specially designed for children's nutritional needs Products, if parents want to drink children's milk with more comprehensive nutrition, they can only buy children's formula milk powder for brewing, and children's formula milk powder can...

Problems solved by technology

[0004] Chinese patent CN102630760A reports a concentrated infant formula milk and its preparation method, which is mainly a liquid dairy product between infant formula milk powder and infant formula liquid milk, using raw cow's milk, desalted whey powder, concentrated whey protein powder, anhydrous butter, vegetable oil, lactose, minerals, citric acid, fatty acid glycerides, carrageenan, citric acid and / or lactic acid, taurine and other raw and auxiliary materials. This product belongs to infant formula concentrated milk, and its nutritional content The concentration of ingredients is 2.0 to 3.0 times that of ordinary infant liquid milk. The product is intended for infants, and vegetable oil is added to the product, but its ingredients are one or more of soybean oil, corn oil, and sunflower oil. No OPO structural fat is added and there are certain differences in other formulation materials and preparation methods

[0005] Chinese patents CN101218940A, CN101218941A, and CN101218942A mainly report a kind of baby liquid milk added with DHA, a kind of baby liquid milk added with mineral elements, and a kind of baby liquid milk added with whey protein, mainly focusing on the formula invention of baby liquid milk , the target of the patented product is infants, although vegetable oil is also mentioned in the formula, but no OPO structural fat is added

[0007] Chinese patent CN102415451A reports a formula whey milk, which mainly focuses on formula invention, and has clear regulations on whey mass ratio, phospholipid mass ratio, and whey protein mass ratio. Although vegetable oil is mentioned, it does not mention the addition of OPO structured lipid

[0008] Chinese patent CN101548698A reports breast-milk formula milk and its preparation method, mainly focusing on the invention that has similar nutritional components to breast milk and the addition of citrate can ensure product stability, but the main scope of application is infants, and the selected Vegetable oil does not contain OPO structural fat, which is different from the present invention

[0009] Adding refined vegetable oil or OPO structural fat has not been used in liquid milk or modulated milk, and the application of OPO structural fat in liquid products is prone to oil floating and oxidation, affecting protein denaturation and high precipitation rate, resulting in product instability
