Abstract
This aims of this study were to 1) know the effect of particle size and extraction time on the characteristics of pandanus fruit extract natural dyes, 2) obtain particle size and extraction time to produce pandanus fruit extract natural dyes with the best characteristics.This study used a factorial randomized block design. The first factor is the size of the particle consists of two levels : 40 and 60 mesh. The second factor is a extraction time consists of three levels : 3, 5 and 7 hours. The experiments are grouped into 3 groups based on the time of implementation, in order to obtain 18 units experiment. Variables observed that the yield, total carotenoid content, color intensity, color score, and the level of color strength.The results showed that the particle size effect on yield, total carotenoids content, balanced color and color strength. Extraction time affect on the extraction yield, the level of brightness (L*), the level of redness (a*), the level of yellow (b*), a score of color and color strength. The interaction of particle size and extraction time affect on total carotenoids content, the level of redness (a*), but does not affect the yield, the level of brightness (L*) and the level of yellow (b*). The particle size of 60 mesh and 5 hour extraction time produce extract natural dyes fruit in best with the following characteristics: yield of 4,80%, total carotenoid content of 0,242%, the level of brightness (L*) of 6,29, the level of redness (a*) -3,70, the level of yellow (b*) 28,93, a score of 4,0 color (red) and strength of color is 6,0 (the most powerful).
