Physicochemical properties: white or almost white powder, insoluble in ethanol, very stable in neutral solution, hydrolyzed in strong acid and elevated temperature, and the end group can be oxidized in alkaline solution. Soluble in water. Odorless and tasteless. The solution can be sterilized by hot pressing at 100-115 ℃ for 30-45 min. Glucans are present in mucus secreted by certain microorganisms during their growth. It is mainly composed of d-gluconan α, 1 → key connection, and the branch chain points are connected by 1 - → 2, 1 → 3, 1 → 4. With the different types and growth conditions of microorganisms, their structures are also different
