Problems solved by technology

However, because fish oil is liquid at room temperature, it has a fishy smell; fish oil is insoluble in water, and the chemical structure of the ethylenic bond of EPA and DHA, that is, the carbon-carbon double bond, is very unstable, sensitive to light, heat, and oxygen, and easily oxidized Decomposition, usually requires low temperature, sealing and dark storage
At present, most fish oil products are in the form of soft capsules, which brings inconvenience to the storage and consumption of fish oil

Abstract

The invention discloses a composite fish oil microcapsule and a preparation method thereof. According to the preparation method, prepared fish oil, algae oil, tea seed oil, kaga oil, vitamin C and vitamin E are compounded, and a mixed oil core material is prepared; chitosan and Arabic gum are selected and dissolved in hot water, and a wall material solution is prepared; the wall material solution is added to the mixed oil core material in proportion, is homogenized and has a condensation reaction, and a composite condensation liquid is prepared; the composite fish oil microcapsule is prepared through spray drying of the composite condensation liquid. According to the preparation method, a process is reasonable, the preparation is simple, raw materials are natural, the use amount is appropriate, and the production cost is low. The prepared composite fish oil microcapsule has a smooth surface, uniform particle diameters, comprehensive nutrition, remarkable efficacy and a long guarantee period and doesn't have fishy smell.

Description

technical field [0001] The invention relates to a microcapsule preparation, in particular to a compound fish oil microcapsule and a preparation method thereof. Background technique [0002] In recent years, with the deepening of research on fish oil, the nutritional value and health function of fish oil have been further affirmed. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) rich in fish oil are both unsaturated fatty acids. After years of scientific research, EPA and DHA have a variety of physiological functions, such as reducing serum cholesterol and low-density lipoprotein levels in the human body, reducing the occurrence of cardiovascular diseases, anti-coagulation, anti-inflammatory and anti-cancer, etc. Among them, DHA also has Brain puzzle, improve eyesight effect. However, because fish oil is liquid at room temperature, it has a fishy smell; fish oil is insoluble in water, and the chemical structure of the ethylenic bond of EPA and DHA, that is, the c...
