Bixin is the pigment with the highest presence in achiote (Bixa orellana L.) and is used in the food, textile, cosmetic and pharmaceutical industry. This research was aimed at obtaining bixin using three extraction solutions. The methodology used had three stages: in the first stage the yield of the crude pigment extracts of the annatto seeds with 40 ° ethanol, 80 ° ethanol and 2% KOH was determined; in the second stage, the yield of bixin in Bixa orellana L. was determined according to the extractant solutions used for each of the three selected annatto varieties and in the third stage the physicochemical composition of the annatto extract was determined. The results indicate that of the three varieties of annatto seeds investigated (green, yellow and red), the highest yield of crude pigment extracts was 7.8%, made to the green variety with 2% potassium hydroxide. The highest concentration of bixin determined by UHPLC was 0,59% w / w as a result of the interaction of the green variety with 80 ° ethanol. The green variety had the highest percentage of moisture in its seeds, with 44,77% and the highest amount of ashes present in the achiote extract was 6,54% w / w, the result of the 40 ° green-ethanol variety interaction.
