Problems solved by technology

These DHA microcapsules with protein or polysaccharide as the wall material can be added to normal milk powder or rice flour for the consumption of people with normal digestion and absorption functions, but for people with poor physique and incomplete digestion and absorption functions such as protein intolerance infants Normal milk powder or rice powder is not suitable for young children, the elderly, patients with major surgery, etc. At this time, milk powder with hydrolyzed protein formula is the best choice, and DHA microcapsule powder of traditional wall materials cannot be well applied to protein hydrolyzed formula milk powder middle

Abstract

The invention provides DHA grease microcapsule powder containing protein polypeptides and a preparation method of the DHA grease microcapsule powder. The microcapsule powder comprises the following components in percent by weight: 20.3-41.2% of protein polypeptides, 8.8-29.7% of protein, 8.8-28.8% of carbohydrates, 20-40% of DHA algal oil, 1% of an emulsifying agent and 0.2% of an antioxidant. The preparation method comprises the following steps: properly controlling the degree of hydrolysis of the protein to obtain a protein and polypeptide mixed wall material, emulsifying and mixing the wall material, a core material, the emulsifying agent and the antioxidant, carrying out high pressure homogenization, and finally carrying out spray drying to obtain the DHA grease microcapsule powder. The wall material of the prepared DHA microcapsule powder contains rich protein polypeptides, so that the microcapsule powder is easier to be digested and absorbed by a human body; and the microcapsule powder not only can be applied to formulas of common milk powder, rice flour, biscuits, milk beverages and the like but also can be applied to a formula of hydrolyzed protein, can be directly used as a solid beverage to be taken with water, and is particularly suitable for children and middle-aged and old people to eat.

Description

technical field [0001] The invention relates to DHA oil microcapsule powder containing protein polypeptide and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Polyunsaturated fatty acids refer to straight-chain fatty acids containing two or more double bonds and a carbon chain length of 18-22 carbon atoms. According to the position of the first double bond carbon atom at the methyl end, polyunsaturated fatty acids can be divided into ω-3 and ω-6 series polyunsaturated fatty acids. Omega-3: α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA); omega-6: linoleic acid (LA), γ-linolenic acid (GLA ) and arachidonic acid (ARA). [0003] Docosahexaenoic acid (DHA) is an important polyunsaturated fatty acid belonging to the omega-3 series. It is an important component of the brain and retina, commonly known as "brain gold", and can maintain and promote the growth of nerve cells. The con...
