Abstract

HOMROY and COLLEAGUES,  (1)Department of Food Science and Technology, National Institute of Food  Technology Entrepreneurship and Management, Kundli, Haryana, India; (2)Department of Food and Nutrition & Food Technology, Institute of Home Economics, University of Delhi, Delhi, India discussed the techniques and principles of omega-3 FA-rich oil encapsulation, its role in improving stability and bioavailability by investigating the potential health benefits of these encapsulated oils.

Background

Omega-3 fatty acids (omega-3 FAs) have been widely recognized for their therapeutic advantages, including anti-inflammatory and cardioprotective properties. They have shown promise in enhancing regulatory function, promoting development and mitigating the progression of diabetes and cancer. The scientific communities, along with industries, are actively endorsing initiatives aimed at increasing the daily intake of lipids rich in omega-3 FAs.

Methodology

Nevertheless, incorporating polyunsaturated FAs (PUFAs) into food products poses several challenges due to their susceptibility to oxidation when exposed to  oxygen, high temperatures, and moisture. This oxidative deterioration results in undesirable flavours and a loss of nutritional value.

Results

Various methods, including physical blending, interesterification, and encapsulation, have been utilized as ways to enhance the stability of edible oils rich in PUFA against oxidation. Encapsulation has emerged as a proven strategy for enhancing the oxidative stability and functional properties of omega-3 FA-rich oils. Multiple encapsulation methods have been developed to stabilize and improve the delivery of omega-3 FAs in food products. The selection of an appropriate encapsulation method depends on the desired application of the encapsulated oil. In addition, encapsulation enhances the bioavailability of omega-3 FAs by promoting increased absorption of the encapsulated form in the intestinal epithelium.

Conclusion

This review  discusses the techniques and principles of omega-3 FA-rich oil encapsulation and its role in improving stability and bioavailability. Furthermore, it also investigates the potential health benefits of these encapsulated oils. This review explores the variations in bioavailability based on encapsulation techniques and processing, offering vital insights for nutrition and product development. © 2023 Institute of Food Technologists®.
