Description

TECHNICAL FIELD

[0002] Carrageenan is a kind of white or light yellow to brown yellow powder or granule, odorless or slightly odor, food additive with sticky taste, which is extracted and processed from Rhodophyceae such as eucheuma, chondrus and furcellaria by water or lye.

[0003] Iota-type carrageenan is also called calcium-sensitive carrageenan, which is a high molecular hydrophilic polysaccharide extracted from eucheuma spinosum and eucheuma isochelatum. Iota-type carrageenan has excellent properties such as gelation, thickening, emulsification, moisture retention, film formation and dispersion stabilization, and is widely used in dairy products, meat products, candies, jellies, puddings, dietary supplements, medicines, cosmetics and health products.
