Abstract:
Many oil seeds contain the necessary fatty acids i.e polyunsaturated fatty acids (PUFAs) like omega-3 and omega-6. These PUFAs are oxidation-prone. Before being applied to or added as a value to food products, PUFAs need to be protected, hence this is accomplished by microencapsulation. This review provides a comprehensive overview of different types of PUFA rich oil seeds and their benefits in human health. Health benefit of pufa include obesity which have become a global health crisis. Clinical studies on obesity, cardiovascular disease, and inflammatory disorders have all shown that omega 3 fatty acids have effects on anti-inflammatory characteristics that can reduce or lower the risk of heart diseases. One of the newest technique to prevent oxidation of PUFAs is microencapsulation. One strategy for maintaining the integrity of delicate chemicals is microencapsulation. It is also a way to create materials with new beneficial features. The method of microencapsulation involves encasing microscopic particles in a polymeric shell. This review also describes different techniques of microencapsulation of PUFAs which includes single and double emulsion technique, spray drying, phase separation coacervation technique, fluidised bed coating, and solvent evaporation.
