Character:

Compared with other chitosans , chitosan oligosaccharide has some special functions and characters, including good aqueous solubility, moisture absorption, and antibiosis and so on.

Application:

1.In Health Food
As the sixth essential element of the body, the chitosan oligosaccharide is of low sugariness, low heat value, asepsis & no side effects and able to reduce blood fat & blood sugar. Biological health food, produced with chitosan oligosaccharide as the main raw materials, not only is favorable to the increment of bacillus in the human's intestine, but also can prevent the generation of toxic fungus and putridity in the human's intestine, raise the quality and quantity of cellulose in the human body, and increase the immunity of airframes. Chitosan oligosaccharide can achieve the use of anticancer by activating the achroacyte in the human body and controlling the generation & expansion of cancer cells.Chitosan oligosaccharide can effectively activate the achroacyte in the human body and improve the body's ability to resist germs.

2.On cosmetics
Chitosan oligosaccharide is mainly concerned with its excellent performance of moisture maintenance and damping.The excellence is more obvious used in cleansing facial milk and all kinds of creams, etc.Adding certain amount of chitosan oligosaccharide to cosmetics not only can prevent the moisture content in cosmetics from disappearing, but also make hydration to the moisture on the cuticle. Other cosmetics with chitosan oligosaccharide are also easy to be absorbed by the skin, and can promote blood circulation.
3.Other industry
With restraining from putrescence,so that Chitosan oligosaccharide can be applied in the agriculture widely.

1. Chitosan-oligosaccharides production by endo-chitosanase and their fungal inhibition capacity in corn tortillas, for detail information click here.

Chitosan-oligosaccharides have become relevant in the last year due to their properties as antimicrobial, enhancing the immune system and fat absorption, among others. In Mexico, the shrimp industry wastes are an important source of chitosan, besides, in commercial corn tortillas only artificial preservatives are used, which does not fit with the actual tendency of consuming natural products. In this work, the antifungal capacity of these oligosaccharides obtained enzymatically was evaluated as preservative in corn tortillas. The chitosan was degraded using a bacterial endo-chitosanase in five series (2, 4, 8, 14 h). The enzyme was inactivated heating the solution, then dialyzed and lyophilised. The fungal inhibition was tested in agar plates. After that, corn tortillas were prepared using the powder obtained at 4 h of enzymatic degradation. The tortillas were packed in sterile plastic bags and incubated at room temperature. These tortillas were then analyzed for detection of filamentous fungi each 5 days. Also, a sensory analysis was realized at day zero. All chitosan-oligosaccharides series were totally water soluble, except for that obtained at 2 h of enzymatic degradation. Of the fungal inhibition tests in agar plates, the most effective hidrolysate was the one obtained at 4 h of reaction (10 mm less of growth of Aspergillus compared with the blank). It was observed in corn tortillas important inhibition of fungal grow: 94000 UFC less in the tortillas with chitosan-oligosaccharide. The sensory analysis did not show significant differences. These results show that the chitosan-oligosaccharides can be used as fungistatic in corn tortillas without altering the organoleptic properties and increase their nutraceutical value.

2. Subacute toxicity of chitosan oligosaccharide in Sprague-Dawley rats, for detail information click here.

A subacute oral toxicity study of chitosan oligosaccharide was performed in Sprague-Dawley rats of both sexes. Each 36 male and female rats were administered by gavage with 500, 1,000 and 2,000 mg/kg/day for 4 weeks (7 days/week), respectively. Examinations regarding clinical signs, body weights, hematological and biochemical parameters, and histopathological examinations were carried out. There were no significant differences in behavior or external appearance, body weight and food consumption between control and treated rats. In addition, no significant differences in urinalysis, hematology, blood biochemistry, relative organ weights and histopathological findings were found in both control and treated rats. In conclusion, it was suggested that subacute toxicity of chitosan oligosaccharide was low and the no-observed adverse effect level was considered to be over 2,000 mg/kg in rats.

3. Antidiabetic effects of chitosan oligosaccharides in neonatal streptozotocin-induced noninsulin-dependent diabetes mellitus in rats, for detail click here!

The antidiabetic effect of chitosan oligosaccharide (COS) was investigated in neonatal streptozotocin (STZ)-induced noninsulin-dependent diabetes mellitus rats. The fasting glucose level was reduced by about 19% in diabetic rats after treatment with 0.3% COS. Glucose tolerance was lower in the diabetic group compared with the normal group. After diabetic rats had been treated with 0.3% COS for 4 weeks, glucose tolerance increased significantly versus the diabetic control group, and glucose-inducible insulin expression increased significantly. In addition, fed-triglyceride (TG) levels in diabetic rats drinking 0.3% COS were reduced by 49% compared with those in diabetic control rats. The cholesterol levels of animals treated with COS were reduced by about 10% in fed or fasting conditions versus the corresponding controls, although the difference was not statistically significant. It was found that COS has a TG-lowering effect in diabetic rats, and that COS reduces signs of diabetic cardiomyopathy such as vacuolation of mitochondria and the separation and degeneration of myofibrils. In conclusion, these results indicate that COS can be used as an antidiabetic agent because it increases glucose tolerance and insulin secretion and decreases TG.
