The chitosan chemical formula is C6H11NO4. Chitosan source is external arthropod skeleton and due to its many properties including degradability in nature, high adsorption capacity, environmental compatibility, cost-effectiveness and non-toxic ability to remove a wide range of colors and metals, rapid kinetics and ultimately derivatives. Much of it is highly regarded. The properties of chitosan often depend on its chemical nature. Among the factors affecting the properties of chitosan: degree of deacetylation, crystallinity, molecular mass and ionic charge.
What foods contain chitosan?
Foods that contain shrimp, clams and crabs contain chitosan. Foods that contain chitosan include:
- Crab and Shrimp Macaroni and Cheese
- Rag Pasta with Shrimp and Crab
- Crab Cake Stuffed Shrimp
- Shrimp and Crab Enchiladas
- Joes Crab Shack Coconut Shrimp
- Shrimp and Crab Empanadas
- and more
If you are allergic to crustaceans, you should not eat foods containing chitosan. Chitosan may interfere with how your blood thinners work. Chitosan may also prevent the absorption of fat-soluble vitamins such as vitamins A, D, E and K. Magnesium may not be absorbed.
What is the food grade of chitosan?
Many retail outlets and popular retail sites offer chitosan food grade products. Almost 50 percent of those are food additives and preservatives and less than 50 percent are antioxidants.
A wide range of chitosan food grade options (such as anesthetics, nutritional enhancers and antioxidants) are available on many sales websites that we can choose from depending on your taste. do. There may even be free products to give you. There are many chitosan food suppliers that produce the most quality products at the most reasonable prices. These suppliers are mostly found in the US, China and China. These products are mostly used in Western Europe, North and South America.
Chitosan is used as an additive in meat and dairy products because of its antimicrobial and antioxidant properties, enhancing shelf life and preventing the change of taste. In food packaging, chitosan films are safe and widely used in food packaging. In addition to being antimicrobial, these packages have good mechanical properties.
Major sources of chitosan and chitin
Chitosan is a combination of glucan with repeating chitin units. Chitin is a naturally occurring mucosal polysaccharide that is abundantly found in the external skeletons of arthropods such as shrimp, crabs, and some plants such as yeast and insect cuticles. Marketed and commercial chitosan is extracted from the external arthropod skeleton such as shrimp. Structurally the difference between chitin and cellulose is only in one acetamide group.
Generally, it can be said that the sources of chitin and chitosan and sources of cellulose exoskeletons of arthropods and some plants. These manufactured products have many applications.
The importance of chitin in the preparation of chitosan is because chitosan in the field of medicine and pharmacology is characterized by its unique characteristics such as: biological compatibility with other substances, high adsorption power, non-toxicity, easy digestibility, and availability as A drug carrier is used.
Characterization of Chitosan from Iranian suppliers
Chitosan is made from chitin from the shrimp shell of Iran, which has its own unique properties. Experiments were carried out on shrimp shells and produced by chitosan proteinurization, mineralization and bleaching. Chitosan was then obtained by deacetylation on chitin. Generally, chitosan produced by Iranian suppliers is not superior to other chitosan produced. Among these features:
- Lower degree of deacetylation
- Higher fat bonding capacity
- Contains less protein and ash impurities
- Indicates a lower limit of vapor permeability
- Higher water bonding capacity
The chitosan produced in terms of color brightness factor was higher than other chitosan. Finally, it can be said that the production of Iranian chitosan with good quality from shrimp shells and scraps is possible, so it can be recommended to Iranian shrimp production and packaging factories.
chitosan price depending on different factors, it is different and does not have a fixed price. Chitosan is used in a variety of fields, such as textiles, food, agriculture, medicine, etc. It has different applications depending on the field and the products it produces, with different prices.
