Goat whey as a coating/protective material in the spray drying process of grape pomace extract
Goat whey, the former "unusable" by-product of the dairy industry, today finds its application in a variety of industries and processes, including the spray drying process, all while promoting the concept of a circular bioeconomy. Grape pomace is a byproduct of the wine industry, that contains a significant amount of polyphenolic compounds, which have already been proven to have numerous beneficial effects on human health. In our study, liquid grape pomace extract was spray-dried using goat whey powder as a coating material. The effects of goat whey on the preservation of polyphenolic compounds from grape pomace extract after spray drying and during different phases of the simulated enzyme-free digestion process in vitro were studied. The encapsulation efficiency of polyphenolic compounds from grape pomace extract during the spray drying process varied from 61.89 % up to 97.34 % depending on the drying temperature, feed flow, and the proportion of coating material. Up to 76.52 % (127.54 mg TOTAL POLYPHENOLIC COMPOUNDS/g dry matter POWDER) of the total amount of polyphenols in spray-dried powder, was released in the small intestine throughout the process of in vitro simulated digestion without enzymes.
