Extracción de antioxidantes de Bixa orellana aplicando tecnología asistida por ultrasonidos

Abstract

Abstract: Bixa Orellana commonly known as achiote, is a shrub that reaches between 2 to 5 meters in height, it is part of the Bixacea family, its reddish or orange seeds are wrapped in a fleshy membrane which gives it its distinctive color, the main compound is in the seed of achiote is 9-cis-norbobixina, A carotenoid used in the food industry due to its safety and resistance to chemical agents. According to the National Cancer Institute, antioxidants are compounds that protect cells from damage caused by free radicals and are found in various fruits and vegetables, to extract antioxidant from Bixa orellana he used the ultrasound-assisted extraction technique that uses high-frequency sound waves to facilitate the release of bioactive compounds. In the determination of antioxidants, we use methods such as ABTS, DPPH, FRAP and the determination of phenolic compounds under temperature conditions of 20, 40 and 60 °C. As a result of extraction, an important antioxidant activity was achieved under optimal temperature conditions, a solvent and solvent sample ratio that favors the antioxidant capacity in the methods performed, highlighting water as an effective solvent to intensify antioxidant activity.
