Alkali Treated Chips

Alkali Treated Chips are an intermediate product made from Eucheuma Cottonii that has undergone alkali treatment to enhance gel strength before further processing into carrageenan. Widely demanded by carrageenan factories overseas with advanced refining facilities. 

Characteristics: Brighter color, low impurities, increased gel strength. 

Usage: Primary raw material for Semi-Refined or Refined Carrageenan production.

Semi Refined Carrageenan

Semi Refined Carrageenan is carrageenan processed through a simpler method than RC but still offers strong gel performance for various industrial applications. Commonly used for further processing or in food manufacturing with specific formulations. 

Advantages: More economical, suitable for high-volume industrial buyers. 

Usage: Sausage, surimi, pet food, processed food stabilizer.

Refined Carrageenan

Refined Carrageenan is a highly purified form of carrageenan produced using filtration and alkali treatment to create fine white powder. It is widely used in premium food-grade industries, dairy, meat processing, desserts, as well as pharmaceutical and cosmetic applications. 

Advantages: High gel strength, cleaner color, high viscosity, food/pharma grade. 

Usage: Ice cream, dairy products, jelly, toothpaste, capsule binder, cosmetic products.
