Non-alcohol rose-apple antioxidant drink with halal fish collagen hydrolysate

Functional drink is currently an interesting study, especially if they are non-alcoholic based as one of the
cornerstones of consumer acceptance in several countries. Roses, which are usually only used as decoration, can actually be
processed into functional drink with high antioxidant activity. This study uses the basic ingredients of roses and apples with
the addition of fish collagen hydrolysate as a non-alcoholic and halal functional drink. Factorial Randomized Design Group
2 factors were used in this study. The first factor was the Rose-Apple ratio variation consisted of 60:40, 50:50, and 40:60
%v/v. The second factor was Fish Hydrolysate Collagen concentration variation consisted of 0, 0.3, 0.5, and 0.7 %w/v. The
data then analyzed with ANOVA at α = 5% and Duncan’s Multiple Range Test. This study result that rose-apple extract 50
(%v/v) with fish hydrolysate collagen 0.7 (%w/v) is the best formulation. The characteristic of the best formulation is pH 2.88
(match with SNI standard about fruit extract which pH maximal 4), total dissolved solids is 29.75oBrix (suitable with SNI
standard which minimal 10.5oBrix), vitamin C is 5.18%, and antioxidant activity is 91.26%. Comparison result with
commercial collagen drink appeared that the best formulation (89.9%) has higher antioxidant activity than commercial product
(19.53%). This study aims that rose-apple drink with fish hydrolysate collagen is a non-alcoholic functional drink that is good
for health.
