Microencapsulation of omega-3 rich flaxseed and fish oils

Omega-3 fatty acids can be widely considered as potential therapeutic agents due to their antioxidant, nutritional, and health aspects. They have unsaturated nature which leads susceptibility oxidation conditions. Therefore, get the maximum benefit minimize or prevent process of oxidation, omega-3 rich oils must protected against atmospheric oxygen. To achieve this objective, two strategies were usually carried out: First addition an antioxidant oils, second, encapsulation process. Here we review chemistry, natural sources, benefits, antimicrobial activity. This highlights obstacles incorporating in foods, particularly concerning oxidation. The importance polyphenols especially curcumin well using different wall materials (sodium alginate, chitosan, clays) microencapsulating fish flaxseed also discussed. Different techniques highlighted well.
