Microencapsulation of vanilla extract

What is it about?

Whey proteins have been reported to be effective for microencapsulation by the spray-drying of volatiles. Its application in microencapsulation vanilla (Vanilla planifolia Andrews) might be an effective process to the preservation of antioxidant activity in the final product. Whey protein is an alternative to produce powder with vanilla extract using spray drying. Microcapsules presented good physicochemical and antioxidant properties, and were not altered during storage period.

Why is it important?

Thus, the results obtained in this work are promising to guarantee the encapsulation of compounds responsible for the antioxidant activity of vanilla extracts, indicating the feasibility of these products for incorporation into functional foods.
