Screening the effect of different extraction methods (ultrasound-assisted extraction and solid-liquid extraction) on the recovery of glycoalkaloids from potato peels: Optimisation of the extraction conditions using chemometric tools

Sammanfattning

Solid-liquid extraction (SLE) (extraction time (5.5-69.5 min) and temperature (25.5-89.5 degrees C)) and ultrasound-assisted extraction (UAE) (extraction time (5-25 min) and temperature (25-85 degrees C), and amplitude (50-100%)) were investigated and optimised as a means to recover steroidal alkaloids from potato peel. Optimisation for the recovery of alpha-solanine, alpha-chaconine, and total glycoalkaloid content (TGA) from potato peels was performed using a central composite design (CCD) and Box-Behnken design for SLE and UAE, respectively. For SLE, the recovery of glycoalkaloids increased with increasing temperature, while time had no significant effect (at p
