Problems solved by technology

[0004] As we all know, DHA is a polyunsaturated fatty acid, which contains multiple "pentadiene" structures and 5 active methylene groups. These active methylene groups make DHA extremely vulnerable to external environmental factors such as light, oxygen, and overheating. , metal elements (such as Fe 2+ 、Cu 2+ Catalytic) and free radicals, chemical reactions such as oxidation, rancidity, polymerization, double bond conjugation, etc., produce fish odor substances mainly composed of carbonyl compounds, and the oxidized DHA not only loses its original nutritional and medical value , and harmful to human

Abstract

A preparation method of high-temperature-resistant microalgae DHA (docosahexenoic acid) oil microcapsule powder comprises steps as follows: (1) raw materials are prepared; (2) whey protein and / or starch sodium octenyl succinate, lyophilic colloid, a food emulsifier, an acidity regulator and a sweetening agent are put into water, heat preservation and stirring are performed, and an aqueous phase liquid is obtained; (3) the aqueous phase liquid is heated to 90-95 DEG C, subjected to heat preservation for 20-30 min, stirred to be fully dissolved and then cooled; (4) a small amount of microalgae DHA oil and an oil-soluble antioxidant are evenly mixed, and a premix is obtained; (5) then the rest microalgae DHA oil is stirred evenly, then added to the premix and stirred to be evenly mixed, and a core material is obtained; (6) the core material is put into the aqueous phase liquid, a water-soluble antioxidant is added, the mixture is stirred and sheared, and an emulsion is obtained; (7) the emulsion is homogenized twice and then sterilized at 80-90 DEG C for 20-25 min; (8) spray drying is performed. The prepared microalgae DHA oil microcapsule powder has excellent high-temperature resistance.

Description

technical field [0001] The invention relates to the technical field of preparation of nutritional products, in particular to a method for preparing high-temperature-resistant microalgae DHA oil microcapsule powder. Background technique [0002] Microalgae DHA oil is a lipid containing docosahexanoic acid (DHA) extracted directly from marine microalgae or fermented from modern biotechnology engineering. Its characteristic components Docosahexaenoic acid has important physiological and health functions for the human body, commonly known as "brain gold", and is a very important long-chain polyunsaturated fatty acid (Long Chain Polyunsaturated Fatty Acids, LCPUFAs). Microalgae DHA oil has been widely considered to have many important physiological functions, not only as a growth and development factor for infants, children and adolescents (such as improving vision and promoting intellectual development), but also as a health element for adults, which can prevent many diseases ,...
