Correlation between the degree of ultrasound-induced cell disintegration and the extraction efficiency of intracellular compounds from purple sweet potato.

ABSTRACT: Ultrasound (US) is an effective intensified extraction technology for natural plant resources, but detailed microscale investigations into US-induced plant cell disintegration are lacking. This study explored the correlation between US-induced (P = 0-800 W, t = 0-40 min) cell disintegration degree and the extraction efficiency of intracellular components from purple sweet potato, also discussing extraction selectivity and visualizing the cell micro-disintegration process. Cell disintegration degree was estimated via electrical conductivity (cell permeabilization index, Z_i) and fractal dimension analysis of damaged cells (cell wall disintegration index, Z_d). Extraction efficiency was evaluated by using the extraction indexes of carbohydrate (Z_c), protein (Z<
