From: Valorisation of food waste in biotechnological processes
Pretreatment/Extraction | Transesterification | Yield* [%, w/w] | Ref. |
|---|---|---|---|
Sonication, at an amplitude of 70% for 10 minutes | Enzymatic transesterification in presence of methanol at 50°C for 48 hours | >90 | [67] |
Microwave assisted transesterification in presence of ethanol at ~260°C for 25 minutes | 56-65 | [66] | |
Supercritical methanol, at 250°C and 1200 psi for 25 minutes | 84 | [65] | |
