Abstract

This study aimed to determine the effect of concentration of fruit juice and duration of immersion on the physical and chemical characteristics of nata de coco colored with senduduk fruit (Melatosma malabathricum L.). The experiment was designed as a Factorial Completely Randomized Design (RALF) with two treatment factors and each treatment was repeated three times. The first factor was concentration of fruit juice (40% b/v and 60% b/v) and the second factor was duration of immersion (4, 6, and 8 hours). The observed parameters on nata de coco colored with fruit were color (lightness (L*), redness (a*), yellowness (b*), color stability and antioxidant. The result showed that the concentration of fruit juice and duration of immersion had a significant effect on lightness (L*), redness (a*), antioxidant, and color stability of nata de coco colored with senduduk fruit; the duration of immersion had a significant effect on yellowness (b*) of nata de coco colored with senduduk fruit; the interaction between two treatment factors had a significant effect on lightness (L*), and antioxidant of nata de coco colored with senduduk fruit. The A2B3 treatment (60% b/v, 8 hour) was the best treatment based on the highest color stability (ΔE*= 44,85) with characteristics of lightness 34,40, redness 34,47 yellowness 3,33 and IC50 value of an antioxidant 345,00 ppm.
