RESEARCH THE INFLUENCE OF SOME FACTORS IN ALOE VERA PROCESSING FOR RECEIVING POLYSACCHARIDES

Abstract

Polysaccharides (PS) and aloin are two compounds that have important biological activities in aloe vera gel. In that, PS are essential, make up more than 55% (on dry weight basis). This survey study the effect of the ultrasonic process, assimilation and heat when treatmenting aloe vera gel. The results show that PS concentration reaches the highest (4298.19 ± 88.42 g/100 g dry weight) when processing aloe vera gel with ultrasound with capacity 262.5W during a 6-
minute, 4 minutes with assimilated implementation at a speed 8000 rev/min, combined incubated gel at 80 oC for 3 hours.
Keywords: polysaccharides, ultrasound, assimilation, heat treatment, Aloe vera.
