Abstract

Abstract:

In order to promote the deep processing of pumpkin and obtain a high value-added pumkin products, the ultrafiltration of pumpkin polysaccharide (PP) solution was carried out using a self-designed pilot-scale ultrafiltration system, and the permeation flux varying with temperature, time, pressure and feeding concentration was measured. Moreover, the membrane pollution during the ultrafiltration was revealed. Results indicated that permeation flux exhibited an increase with increasing temperature and pressure but a decrease with increasing time and feeding concentration, and a membrane pollution difficult to recover may occur due to prolonged operating time.

Key words: ultrafiltration, concentration, pumpkin polysaccharide
