Multifaceted roles of foam-mat freeze-dried catechins nanoencapsulation to enhance catechins stability and bioaccessibility, and quality of green tea catechins-fortified milk.

ABSTRACT: Catechins, widely used as functional ingredients and health supplements, face usage limitations due to their poor stability and bioaccessibility. In this study, encapsulation techniques including nanoemulsion and foam-mat freeze-drying were utilized to enhance the stability and bioaccessibility of catechins. Catechins nanoemulsion (CaNE) was ultrasonically fabricated and foam-mat freeze-dried CaNE (FD-CaNE) was prepared by mixing with a blend of maltodextrin and gum arabic as wall material and foaming with hydroxypropyl methylcellulose before freeze drying. Unencapsulated catechins (UN-Ca), CaNE, and FD-CaNE were fortified in pasteurized milk to improve its functional properties. FD-CaNE was shown to be the best at preserving total flavonoid content (TFC) and catechins' antioxidant activit
