Supercritical fluid extraction of β-carotene from ripe bitter melon pericarp
Study ascertained the recovery of β-carotene from enzyme-treated (enzyme load of 167 U/g) pericarp of ripe bitter melon using supercritical fluid extraction (SFE) technique. Effect of different pressure (ranged from 150–450 bar), carbon dioxide (CO(2)) flow rates (ranged from 15 to 55 ml/min), tempe...

Sumario: | Study ascertained the recovery of β-carotene from enzyme-treated (enzyme load of 167 U/g) pericarp of ripe bitter melon using supercritical fluid extraction (SFE) technique. Effect of different pressure (ranged from 150–450 bar), carbon dioxide (CO(2)) flow rates (ranged from 15 to 55 ml/min), temperatures (from 50 to 90 °C), and extraction periods (from 45–225 minutes) were observed on the extraction efficiency of β-carotene. Results showed that extraction pressure (X(1)) among extraction parameters had the most significant (p < 0.05) effect on extraction efficiency of the β-carotene followed by allowed extraction time (X(4)), CO(2) flow rate (X(2)) and the temperature of the extraction (X(3)). The maximum yield of 90.12% of β-carotene from lyophilized enzymatic pretreated ripe bitter melon pericarp was achieved at the pressure of approx. 390 bar, flow rate of 35 mL/min, temperature at 70 °C and extraction time of 190 min, respectively. Based on the accelerated storage study the 70% retention shelf life of the β-carotene into extract was estimated up to 2.27 months at 10 °C and up to 3.21 months at 5 °C. |
