The reseach is to determine the effect of solvent type and ohmic heating electrical voltage in the betacyanin pigment extraction process. The methodology used is a paired T test, the first factor is solvent type: distilled water, Nacl 0,25% and citric acid 0,25%, and the second factor is electrical voltage: 30V, 40V and 50V.data analysis using pH and temperature stability data analysis (parameters measured in stability temperatures are pigment content and lightness. The result showed that the addition of pH 5 to the betacyanin pigment extract did not produce significant difference, the addition pH 7 to the betacyanin pigment extract did not poduce a significant difference, indicating that the betacyanin pigment extract stored at refrigerator and incubator temperatures did not produce a significant difference, indicating that storage in refrigerator temperature in betacyanin pigment extract produced no significant difference in lightness, while at incubatore temperature a produced significant difference in lightness
