Problems solved by technology

[0004] The fish oil/algae oil microencapsulation products on the existing market are mainly produced by traditional spray drying technology. The microcapsules prepared by this process mainly have the following shortcomings: First, the size of the microcapsules is generally large, ranging from tens of microns or even to Hundreds of microns, and the particle size is not uniform, which limits its effective absorption on the intestinal mucosa to a certain extent; secondly, the inherent high

Abstract

The present invention relates to a fish oil/algal oil microencapsulated product rich in polyunsaturated fatty acids (PUFA) essential to the human body and a production process thereof. The microcapsule is prepared by means of a premix membrane emulsification process and a complex coacervation method using sodium alginate and chitosan which are biodegradable, have health-care functions and are cheap and readily available as wall materials. The prepared fish oil/algal oil microcapsule is uniform in particle size, and the particle size can be controlled at hundreds of nanometers-tens of microns. The prepared fish oil/algal oil microcapsule has the advantages of good sustained release and enteric digestion effects, high absorption efficiency, low production cost, etc., and can be widely applied to food nutrition enhancement and health-care food.

Description

technical field [0001] The invention relates to microencapsulation technology in the field of food processing, in particular to a fish oil / algae oil microcapsule product and a preparation process thereof. Background technique [0002] Deep sea fish oil / algae oil is rich in polyunsaturated fatty acids (PUFA) which are essential for human body. The n-3 series of docosahexaenoic acid (DHA) and the n-6 series of arachidonic acid (ARA) in the PUFA family are two very important PUFAs, which are very high in nerve tissue, such as in Both PUFAs are involved in brain development and function, both in retinal photoreceptor cells and in the gray matter of the brain. Of these, DHA is essential for neurological and visual development, while ARA is critical for normal development and proper use of the vascular system. In addition, prostaglandin (PG), a metabolite of PUFA, also plays a crucial role in brain development. Expression of PG and its receptors is accelerated in the neonatal b...
