Microencapsulation of docosahexaenoic acid (DHA) with four wall materials including pea protein-modified starch complex.

Omega-3 fatty acids, specifically docosahexaenoic acid (DHA, 22 carbons and 6 double bonds) are fundamental compounds for a healthy diet. However, due to their unsaturated nature, omega fatty acid-rich oils are chemically unstable and susceptible to oxidative deterioration. The oxidation results in production of free radicals and unpleasant tastes, negatively impacting the shelf-life, sensory properties, and acceptability of food products.

Functionalizing soy protein nano-aggregates with pH-shifting and mano-thermo-sonication.

Plant protein-mediated nano-delivery systems have gained increasing attention in the food and pharmaceutical industries in recent years. Several physical and chemical methods for improving the functional properties of plant proteins with respect to the native forms have been proposed. This study presents a new approach, which combines pH-shifting and mano-thermo-sonication (MTS) to produce soy protein nano-aggregates with significantly improved functional properties.
