Carrageenan is a natural water-soluble polysaccharide extracted from marine red algae such as Euphorbia milii and Gracilaria salina. It is also one of the most widely used hydrophilic colloids in the food industry. With its excellent thickening, gelling, stabilizing, and emulsifying properties, it has been widely adopted in everyday food, daily chemical, and even pharmaceutical fields, becoming a safe and reliable functional additive.
From a physicochemical perspective, carrageenan possesses unique solubility, dissolving in hot water at around 80°C to form a viscous, transparent solution, but insoluble in cold water and organic solvents. Its gel exhibits thermal reversibility, melting upon heating and solidifying upon cooling. It demonstrates excellent stability in neutral and alkaline environments and can be compounded with various colloids to significantly enhance the elasticity, water retention, and stability of products. Based on structural differences, commercial carrageenan is mainly divided into three categories, each with its suitable application scenarios: Kappa type forms high-strength gels, Iota type gels are soft and elastic, and Lambda type is non-gellable, primarily serving as a thickener and stabilizer.
The food industry is a core application area for carrageenan. In dairy products, it prevents yogurt and milk drinks from separating and settling, resulting in a smooth and rich texture. In meat products, carrageenan locks in moisture and binds the meat, making sausages and luncheon meat tender and juicy while extending shelf life. In desserts such as jelly, pudding, and candy, it acts as a natural gelling agent, providing a chewy and non-sticky texture. Furthermore, it is widely used in sauces, milk tea, and plant-based protein drinks, serving as a thickener, suspending fruit pulp, and homogenizing the texture.
Besides the food industry, carrageenan has a wide range of applications. In the daily chemical industry, it can be added to toothpaste and skin care products to improve the stability and smoothness of the paste; in the pharmaceutical industry, thanks to its good biocompatibility, it can be used to make pharmaceutical excipients and sustained-release drugs, and also has a certain antiviral adjuvant effect.
Concerns about the safety of carrageenan are largely unfounded. It has been approved by the Codex Alimentarius Commission, the European Union, the US FDA, and my country's food safety authorities. Food-grade carrageenan added in compliant and appropriate amounts can be metabolized normally by the human body and will not harm health. It is a highly cost-effective natural functional ingredient.
