[0004] Patent No. CN201510688093.6 "A Method of Using Konjac Gum as Wall Material to Embed Microalgae Oil to Make Microcapsules" This patent discloses that the mass ratio of wall material to core material is 4.37, and the oil content is low, only 18.6%; CN201510106829.4 "High Stability Algae Oil DHA Microcapsule Powder and Its Preparation Method" discloses that water-soluble dextrin, modified starch, and glucose powder are used to embed algae oil DHA. The embedding effect is better, but the oil content is relatively low. In addition, directly adding 70-80°C hot water to the modified starch may cause agglomeration and increase the difficulty and time of stirring and dissolving

Abstract

The invention provides a microalgal oil microcapsule and a preparation method thereof. A core material is mainly microalgal oil, and a wall material comprises components of casein, porous starch, beta-clodextrin, chitosan and mannose oligosaccharides, and particularly, the wall material comprises the components in percentage by mass as follows: 40%-60% of casein, 30%-40% of porous starch, 1-10% ofbeta-clodextrin, 1-10% of chitosan and 1-10% of mannose oligosaccharides; and the core material also contains an emulsifier, a stabilizer and an antioxidant. The microalgal oil microcapsule has highoil content, being 50% and embedding rate, being higher than or equal to 95%, bulk density is higher than or equal to 0.4 g / ml, and fluidity is very good; the surface oil content is 0.58%-1.75%, and is low, the peroxide value is 0.023-0.22 g / 100 g and is low, and the microcapsule can be stored for three months or longer at 40 DEG C, which indicates that the shelf life is two years or longer at 25DEG C, so that the microcapsule has quite high stability; and the microcapsule disperses well in water, is noncaking, and cannot change original solubility and dispersibility when added to other foodand can be directly added to powdered food, so that the application range is wide.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, in particular to a microalgae oil microcapsule and a preparation method thereof. Background technique: [0002] Microalgae oil is a pure vegetable oil extracted from fermented algae, containing very high omega-3 polyunsaturated fatty acids, such as docosahexaenoic acid (DHA), eicosapentaenoic acid ( EPA), polyunsaturated fatty acids have the effect of preventing cardiovascular disease and anti-cancer, and promote blood circulation by reducing cholesterol and fat content. DHA is not only an important component of the brain and retina, but also very important for the growth and development of the body. EPA has Lower blood pressure, anti-inflammation effect, and also have a certain effect on the treatment of coronary heart disease. [0003] The polyunsaturated fatty acids in algae oil are easy to oxidize, which increases the difficulty of storage and transportation. The liquid oil ...
