FAQ

What are the physical and chemical properties of λ-Carrageenan (CAS: 9064-57-7)?

λ-Carrageenan (CAS: 9064-57-7) is a linear polysaccharide with a high molecular weight (100,000-1,000,000 g/mol). It has a crystalline structure and is soluble in hot water. It is non-toxic, pH-sensitive, and exhibits strong gelling properties. Its reactivity is low, making it stable under various conditions.

How is λ-Carrageenan (CAS: 9064-57-7) typically synthesized?

λ-Carrageenan (CAS: 9064-57-7) is typically synthesized through the depolymerization of κ-carrageenan using enzyme or chemical methods. Commonly, the process involves the action of endoglucanase or sulfuric acid, followed by purification and fractionation to obtain the desired λ-carrageenan.

What industries use λ-Carrageenan (CAS: 9064-57-7)?

λ-Carrageenan (CAS: 9064-57-7) is widely used in the food industry for its gelling, thickening, and stabilizing properties. It is also utilized in the pharmaceutical and cosmetic industries for its film-forming and emulsifying capabilities. Additionally, it has applications in paper production and as a thickener in industrial products.

What precautions should be taken when handling λ-Carrageenan (CAS: 9064-57-7)?

When handling λ-Carrageenan (CAS: 9064-57-7), it is important to wear appropriate personal protective equipment (PPE) such as gloves and goggles. Proper ventilation should be ensured, and the material should be stored in a cool, dry place. In case of spills, they should be cleaned up using appropriate absorbents, and the area should be thoroughly washed. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
