Embodiment 1
[0040] A kind of extraction technology of tea polysaccharide of Moringa oleifera, comprises the following steps:
[0041] (1) Pretreatment of raw materials: first pulverize the Moringa oleifera tea to obtain tea powder, then put the tea powder into an extruder and add 7% water by weight to squeeze to obtain tea dregs and tea liquid for subsequent use;
[0042] (2) Primary leaching: put the tea dregs into water at 80°C with a liquid-to-solid ratio of 60mL / g, extract with ultrasonic waves with a frequency of 45kHz for 105min, filter to obtain a primary filter residue and a primary filtrate, and set aside;
[0043] (3) Secondary leaching: put the primary filter residue into water at 25°C, the liquid-to-material ratio is 60mL / g, and add 0.08% of the filter residue weight to be composed of cellulase and pectinase with a mass ratio of 3:1 Mixing enzymes, extracting for 60 minutes with ultrasonic waves with a frequency of 45kHz, filtering to obtain secondary filter residue and second...
