Technical Abstract: Awareness of the health benefits associated with the polyunsaturated acids such as alpha linolenic (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), has generated interest in formulating foods and dietary supplements with these compounds. However, the highly unsaturated structure of this class of compounds is prone to oxidative processes with the associated loss of bioactivity and the generation of malodorous degradation products. Encapsulation techniques show promise to mitigate the detrimental oxidation process and preserve the quality of products formulated with these compounds. Recent investigations demonstrated that network polymers prepared from glycerol and combinations of adipic acid and citric acid could be used as a matrix material for lipid compounds. The dissolution of the matrix and concomitant release of the lipid compound entrapped within the matrix was observed to be a function of the polymer properties, e.g., amount of excess acid and the extent of cross-linking, and the pH of the surrounding environment. These biobased polymers were also derivatized to impart antioxidant properties to the matrix itself. Alternatively, tocopherols entrapped with the polyunsaturated acids fatty acids provided an antioxidant function during storage and upon release when the matrix dissolved. It is anticipated that this approach could be applied to complex food and feed formulations.
