Carrageenan is a hydrophilic colloid, also known as agar, seaweed gum, or carrageenan gum, because it is extracted from red algae such as Eucheuma, Agar, and Carrageenan. Its chemical structure consists of calcium, potassium, sodium, and ammonium salts of a polysaccharide sulfate ester composed of galactose and dehydrated galactose. Due to the different sulfate ester binding forms, it can be classified into Kappa, Iota, and Lambda types. It is widely used in the manufacture of jellies, ice cream, pastries, soft candies, canned goods, meat products, eight-treasure porridge, bird's nest soup, stews, cold dishes, and more.

Gel Formation and Texture Regulation: κ-carrageenan forms a brittle gel in the presence of potassium ions, ι-carrageenan forms an elastic gel in the presence of calcium ions, while λ-carrageenan cannot gel but can efficiently thicken. By adjusting the type, concentration, and ionic environment, the texture of the product can be precisely controlled (e.g., the crispness of jelly, the smoothness of cheese).
Highly Effective Thickening and Suspension Stabilization: Carrageenan significantly increases the viscosity of the aqueous phase, forming a three-dimensional network structure that effectively suspends solid particles such as fruit pieces and cocoa powder, preventing sedimentation and stratification. Its thermally reversible gelling properties facilitate processing and flavor optimization.
Protein Reaction and Emulsion Stabilization: It interacts electrostatically with milk proteins (especially κ-casein), preventing phase separation in dairy products during heat treatment. It is widely used for stabilizing dairy systems such as chocolate milk and ice cream.
Film Forming and Moisturizing Effects: After drying, it forms a transparent film, used in food preservation coatings or pharmaceutical capsules. Its strong hydrophilicity locks in moisture, providing long-lasting hydration in skincare products.
Food Industry: Gel and Stabilizer. Used to provide a gel texture in desserts such as jellies, puddings, and gummies; prevents whey separation and improves texture in dairy products (such as yogurt and cheese); used as a water-retaining agent and slicing aid in meat products (such as ham and luncheon meat).
Chemicals and Pharmaceuticals: Used as a binder and paste stabilizer in toothpaste, providing a smooth paste and long-lasting foam; used in personal care products such as facial cleansers and shower gels to adjust viscosity and skin feel; used as a sustained-release capsule material or suspension stabilizer in pharmaceutical formulations.
Pet Food and Industrial Applications: Added to canned pet food and wet food as a gel matrix and moisture retainer; used as a setting or thickening ingredient in air-freshening gels and water-based coatings; used as a solidifying agent for plant tissue culture media.
Special Diets and Innovative Foods: Used in vegetarian products (such as plant-based cheese and vegetarian ham) to mimic the texture of animal products; used in molecular gastronomy to prepare spherical ingredients such as "caviar"; used as a beer clarifying agent to remove cold turbidity proteins.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
