This study aims to develop natural colorant from fully ripe gac fruit that comes in liquid and powder from. Major process includes water extraction and dehydration of gac fruit aril then contained in an opaque plastic bottles to protect the product for sunlight as well as control the degradation by moisture, oxygen and heat. Standard testing conducted such as color analysis shows that gac fruit aril colorantproduces a “yellowish red” hue. Fat analysis reveals that among the three variants of gac fruit aril colorants: liquid, powder (A) obtained fat content. However, no peroxide value was detected. The average pH level of all colorants samples is 7.4 or slightly alkaline. The working wavelength of the liquid colorants falls in the yellow-green region (400-465nm). While both powder A and B colorants has maximum absorbance at the yellow region (464-482nm). Liquid colorant produces brighter color compared to the powdered and very minimal residue formed upon mixing with water. Overall, both liquid and powder forms of colorant derived from gac fruit aril can be use as coloring agent.
