Long‐chain omega‐3 oils: Current and future supplies,food and feed applications,and stability

Increasing recognition of the health benefits of omega‐3 long‐chain (⪈C₂₀) polyunsaturated fatty acids (omega‐3 LC‐PUFA or LC omega‐3 oils) continues. But new sources are needed, with recent developments with novel land plants showing promise. The value of existing and future sources LC omega‐3 oils occurs through aquaculture, livestock and other feeding. There is also a need toenhance the stability of oils containing LC omega‐3 oils. Challenges include increasing DHA levels in land plants, increasing oxidative stability in food products and product labeling. Consumers have difficulty recognizing and differentiating long‐chain and shorter‐chain (SC, C₁₈) omega‐3 PUFA, both of which are referred to as “omega‐3” fatty acids.
