1, color
Light yellow solid powder, easily dissolve in water.
2, stability
There is resistance, good stability, does not decompose at high temperature under the condition of 140 deg. Under acidic conditions, with good thermal stability. Oligochitosan can be used in acidic drinks and cooking food.
3, water solubility, molecular size is decided the water-soluble low main factors and chitosan is insoluble in water, and chitosan oligosaccharide completely dissolved in water.
4, hygroscopicity and moisture retention: chitosan oligosaccharide with large hygroscopicity and moisture retention capacity, is obviously better than that of hyaluronic acid, sodium lactate and glycerol.
5, amino features: three important characteristics has because of its chemical structure containing amino group.
Alkaline (1). Body fluid acid-base degree requirements is very strict of, pH value needs to be restricted in a very narrow range, otherwise physiological function by adverse effects, will produce serious acid-base poisoning. Due to the human catabolite is acidic, so humoral acidity of the tendency, the experts recommended to eat more alkaline food is the truth. The chitin is the only natural alkaline polysaccharide, the alkalinity is determined by its amino group.
(2) reduction. Is the anti free radical effect, because the free radical is important pathogenesis of almost all elderly patients with chronic diseases. Therefore, antioxidant is very important.
(3) adsorption. Can combine many harmful substances and heavy metals.
