Chitosan oligosaccharide with the CAS number 148411-57-8 is a high - quality product from our factory supply. It is a low - molecular - weight oligosaccharide derived from chitosan. The product usually appears as a white or off - white powder with good solubility in water.
It has a low viscosity, which makes it easy to handle and incorporate into various formulations. The degree of deacetylation is an important parameter, and our product generally has a high degree of deacetylation, which endows it with excellent biological activities. The molecular weight is relatively low, typically in the range of several thousand Daltons, enabling it to penetrate cell membranes easily and exert its biological effects more effectively.
1. **Agriculture**: In agriculture, chitosan oligosaccharide can be used as a plant growth regulator. It can stimulate the growth of plants, enhance their resistance to diseases and pests, and improve the quality and yield of crops. For example, it can induce the production of phytoalexins in plants, which are natural defense compounds against pathogens.
2. **Food Industry**: It is a valuable ingredient in the food industry. It can be used as a preservative due to its antibacterial and antifungal properties. It can also be added to functional foods as a dietary fiber, which helps to regulate the intestinal flora and improve digestion.
3. **Cosmetics**: In the cosmetics field, chitosan oligosaccharide is used for its moisturizing and anti - aging effects. It can form a thin film on the skin surface, preventing water loss and keeping the skin hydrated. Additionally, it may promote collagen synthesis, reducing the appearance of wrinkles.
4. **Pharmaceutical Industry**: Chitosan oligosaccharide has potential applications in the pharmaceutical industry. It has immunomodulatory, antioxidant, and hypoglycemic effects. It can be developed into drugs or health supplements for treating and preventing various diseases.
1. **Agricultural Use**: For foliar spraying, dissolve the chitosan oligosaccharide in water at a concentration of 50 - 200 ppm. Spray the solution evenly on the leaves of plants during the growth period, preferably in the morning or evening. For soil application, mix the product with water or fertilizers at a rate of 1 - 5 kg per hectare and apply it to the soil around the roots.
2. **Food Industry Use**: When used as a preservative, add the appropriate amount (usually 0.1% - 0.5% of the total food weight) to the food product during the production process. As a dietary fiber, it can be directly added to food formulations such as bread, yogurt, and beverages.
3. **Cosmetics Use**: In cosmetic formulations, it can be added at a concentration of 0.5% - 5%. First, dissolve it in a suitable solvent (such as water or ethanol), and then add it to the cosmetic base during the mixing process.
4. **Pharmaceutical Use**: The dosage and usage of chitosan oligosaccharide in the pharmaceutical field depend on the specific formulation and the patient's condition. It is usually taken orally, and the dosage should be determined by a doctor or a professional pharmacist.
1. **Agricultural Case**: In a tomato farm, farmers used chitosan oligosaccharide for foliar spraying. After a season of use, the incidence of tomato diseases such as early blight and late blight decreased by 30%. The yield of tomatoes increased by 15%, and the fruit quality improved, with a brighter color and better taste.
2. **Food Industry Case**: A bakery added chitosan oligosaccharide to their bread as a preservative. The bread had a longer shelf - life, remaining fresh for 3 days longer than the bread without the additive. Customers also reported that the bread had a softer texture and better flavor.
3. **Cosmetics Case**: A cosmetics company developed a moisturizing lotion containing chitosan oligosaccharide. After a 4 - week trial on 100 volunteers, 80% of the volunteers reported that their skin felt more hydrated, and the appearance of fine lines on their faces was reduced.
4. **Pharmaceutical Case**: In a clinical trial on diabetic patients, the patients took chitosan oligosaccharide supplements for 3 months. At the end of the trial, their blood glucose levels showed a significant decrease, and their immune function was improved.
