Abstract

Changes in people^s lifestyles through the implementation of a good food diet are carried out by consuming foods containing bioactive compounds. ^Functional milk products contain bioactive components to improve metabolism, the immune system and digestion. Optimization of functional milk products can be enriched through fortification of by-products that are rarely utilized, even though they have the potential to be explored and developed as natural antioxidants. The addition of dragon fruit skin extract at a concentration of 5% produces the best red bean sprout milk yogurt with pH (4.34), viscosity (4006 mPas), antioxidants (26.17%RSA), and sensory (4.02). Yogurt drink with the addition of 3% mangosteen skin extract has a viscosity value of 74.65 cp, lightness (L) 79.89, redness (a *) 0.14 yellowness (b *) 2.32, organoleptic test of viscosity with a score of 2.84 (slightly thick), organoleptic test of color 3.52 (brownish white) and organoleptic test of texture with a score of 2.12 (rather smooth). Based on several research results, it shows that the potential of local by-products can provide significant results for use in functional milk products.
