Ultrasound emulsification of supercritical extracts of biquinho pepper (Capsicum chinense)

Abstract

Capsinoids, recently indentified in Biquinho peppers (BP), presents several biological activities, as prevention of tumorigenesis and increase of energy expenditure. In order to verify if the emulsification process could increase the bioactivity of the supercritical fluid (SFE) extracts from BP, emulsified systems were produced by ultrasound emulsification process using Hi-Cap and Snow flakes as emulsifers. The results indicate that the Snow flakes was more effective in producing small particles, as well as higher emulsification time and power (6 min and 720 W). It was not observed an increase in biological activity of the extract with the emulsification process.
