Introduction--The increase in Aloe Vera as a raw material in the industry has led to a high generation of waste. The high content of chlorophyll contained in the peel can be extracted with solvents and applied as colorants in food-type agro-industry processes. Objective--Extract chlorophyll in the form of oleoresin by means of solvents from the shells of aloe (Aloe barbadensis) for use as a pigment. Methodology--Three solvents (acetone, ethanol and carbon tetrachloride) were used for the extraction of the chlorophyll contained in the Aloe Vera shell, keeping the fixed parameters of concentration, volume, centrifugation speed, optical density, temperature and storage time, comparing the total chlorophyll content and the antioxidant power by ABTS and DPPH with those obtained from a commercial sample. Results--The highest total chlorophyll content was 155.8 ml/g with acetone, this being the best extractive solvent, the antioxidant power test was 13 826 ml equivalent of Trolox per 100 grams of raw material and 18 125 mg eq. Trolox/100g. Conclusions--Chlorophyll in the form of oleoresin extracted from aloe peels with acetone shows the best results compared to the use of ethanol and carbon tetrachloride as solvents.
