Abstract

Yellow sweet potato has some clone with different color level and contains carotenoid pigment. The pigment can be extracted by fat-soluble such as ether and hexane. The obtained pigment can be used as a dye of food product such as butter cream. The purpose of this research is to know the type of carotenoid pigment contained in three types of sweet potato clone, to know the influence of sweet potato clone and type of soluble to the quality of carotenoid pigment. This research is conducted on March until Juny, include in two stages. Stage I is conducted by using factorial RAK method with two factors and repeated 3 times. Stage I is the extraction of carotenoid pigment. Factor I is sweet potato clone (K1=Betha-1, K2= Betha-2, K3= MSU 03287-21, K4=Betha-3), and factor II is type of soluble (P1= ether, P2= hexane). Stage II is the application of carotenoid pigment extract on butter cream. It is conducted by using RAL method that simply set by using additional factor of carotenoid pigment (K0= 0%; K1= 1%; K2= 2%; K3= 3%). = 477.2); color intensity: 29,16 lightness level (L); 15,05 redness level (a+); 17,55 yellowness level (b+). The application result of carotenoid pigment is 3% contributing color intensity on butter cream: lightness level (L) from 92.2 become 87.4; redness level (a+) from 6.1 become 11.6; and yellowness level (b+) from 11.4 become 33.0. = 477.2); color intensity: 33,33 lightness level (L); 11,10 redness level (a+); 21,10 yellowness level (b+) and Betha-3 by using ether soluble type. It contains: 74,08% water content; 7,18 pH; absorbance of 9,78 ( = 477,2); color intensity: 32,33 lightness level (L); 12,15 redness level (a+); 25,15 yellowness level (b+); the MSU 03287-21 by using ether soluble type. It contains: 71,01% water content; 7,96 pH; absorbance of 8,41 ( = 477,2); color intensity: 32,8667 lightness level (L); 12,6000 redness level (a+); 10,6333 yellowness level (b+); Betha-2 by using ether soluble type. It contains: 77,71% water content; 7,40 pH; absorbance of 3,87 (The research result shows that each of klon that used have an different pigment Betha-1 by using ether soluble, MSU 03287-21 by using ether soluble and Betha-3 by using ether soluble conclude of xantofil, wherefore Betha-2 by using ether soluble, Betha-3 by using ether soluble, Betha-1 by using hexane soluble, Betha-2 by using hexane soluble and MSU 03287-21 by using hexane soluble are conclude karoten. The best quality of karotenoid pigment of yellow sweet potato is obtained from Betha-1 by using ether soluble type. It contains: 83,88% water content; 7,21 pH; absorbance of 2,9924.
