Description

Technical Field

[0001] The invention relates to the technical field of goat milk powder, in particular to a method for preparing selenium-rich and high-calcium goat milk powder. Background Art

[0002] Selenium is beneficial to the human body, can improve human immunity and prevent certain diseases. Selenium-rich foods are divided into two types: natural selenium-rich foods and artificial organic selenium foods. Natural selenium-rich foods refer to crops grown in soil with high selenium content, such as selenium-rich rice, black yam, black sesame, black beans, black peanuts, black rice, etc.

[0003] Goat milk powder is known as the best among milk powders. It has the following advantages: compared with cow milk, the fat and protein molecules of goat milk are smaller, which makes it easier for the human body to digest and absorb; goat milk powder is rich in calcium, which helps maintain healthy bones and teeth; goat milk powder is also rich in vitamins and minerals, providing the human body with necessary nutrients. At present, there are no goat milk powder products rich in selenium. In order to obtain a healthier and more beneficial milk powder formula, we need to continue to innovate and explore to enrich the nutritional content of goat milk powder. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention discloses a method for preparing selenium-rich and high-calcium goat milk powder, comprising the following steps: Step 1: sterilize raw goat milk; Step 2, spray drying or freeze drying the raw goat milk sterilized in step 1 to obtain goat milk powder; Step 3: Select 710-800 parts of the goat milk powder obtained in step 2 by weight and put it into a homogenizing device, and select 70-80 parts of oligosaccharides, 48-53 parts of desalted whey powder, 70-80 parts of whey protein powder, 20-40 parts of inulin, 1-3 parts of complex vitamins, 1-3 parts of complex minerals, 5-10 parts of calcium carbonate, and 0.1-0.3 parts of N-acetylneuraminic acid powder by weight, and obtain selenium-rich high-calcium goat milk powder after homogenization and drying.

[0005] As a preferred embodiment of the present invention, the sterilization treatment in step 1 is a high-temperature sterilization treatment at a temperature of 80-90° C. for 20-30 seconds.

[0006] As a preferred embodiment of the present invention, the temperature of the freeze-drying treatment in step 2 is -70 to -50°C, and the treatment time is 15 to 30 hours.

[0007] As a preferred embodiment of the present invention, the homogenizing equipment in step three is a constant temperature stirring homogenizing equipment.

[0008] As a preferred embodiment of the present invention, the composite mineral is one or more of ferrous sulfate, zinc sulfate and selenium-enriched yeast.

[0009] As a preferred embodiment of the present invention, the complex vitamin is one or more of vitamin A, vitamin D, vitamin E, vitamin B6 and vitamin C.

[0010] The beneficial effects of the invention are as follows: the invention prepares the product by adding isomaltooligosaccharide, desalted whey powder, whey protein powder, inulin, compound vitamins, compound minerals, calcium carbonate and N-acetylneuraminic acid powder into goat milk powder, and uniformly mixing the mixture; the overall preparation process is simple, and the cost can be effectively reduced; the compound vitamins added therein contain a variety of vitamin components, and are combined with compound mineral components rich in elements such as iron, zinc and selenium, so that the goat milk powder is a product rich in mineral elements such as selenium and has comprehensive nutrition, which makes up for the lack of goat milk powder products rich in trace mineral elements and effectively meets market demand.
