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.
Highlights
The identification of capsinoids in Biquinho peppers (BP) opened a new possibility for the valorization of this Brazilian native cultivar
The main objective of this study was to verify if emulsified systems of capsiate-rich BP extracts promotes an increase of the bioactivity by the determination of the antioxidant capacity in relation to extract obtained by CO2 supercritical extraction (SFE)
For the Snow flakes emusifier, particle diameter ranged from 373 to 320 nm, and the smallest particle size was obtained at 10 g/L emulsier concentration and 10% (v/v) oil
Summary
The identification of capsinoids in BP opened a new possibility for the valorization of this Brazilian native cultivar. The production of emulsified systems using capsiate-rich extracts may increase the bioavailability of these compounds and could be applied in the food and pharmacological industries. The main objective of this study was to verify if emulsified systems of capsiate-rich BP extracts promotes an increase of the bioactivity by the determination of the antioxidant capacity in relation to extract obtained by CO2 supercritical extraction (SFE).
