Valorization of pineapple waste for the extraction of bioactive compounds and glycosides using autohydrolysis
| Resumo: | Autohydrolysis process, an alternative technology that uses only water as extraction solvent, was evaluated for the extraction of glycosides and polyphenols from pineapple waste. A Box-Behnken design was carried out using different temperatures (150200°C), solid-liquid ratio (1:401:10w/v) and reaction time (1545min). The best condition for the production of glucose (27.6g/L) and fructose (33.8g/L) was 150°C, 30min and 1:10w/v while the highest amount of extracted total polyphenols (1.75g/L) was obtained at 200°C, 30min and 1:10w/v solid-liquid ratio. In all treatments were detected gallic acid, hydroxybenzoic acid, chlorogenic acid, epicatechin, coumaric acid and caffeic acid. These results indicate autohydrolysis as a valuable alternative for the sustainable extraction of high value-added molecules for further use in industrial, food, cosmetic and health applications. |
