Overview of Curdlan Gum E418 Food Additive
1，What is Curdlan Gum E418?
Жевательная резинка Curdlan is a microbial exopolysaccharide (EPS) produced by the bacteria Alcaligenes sp. It consists of D-glucose in the C1 and C2 bits with β-glucosidase forming a non-ionic polysaccharide chain. It’s notable for its solubility in alkaline solutions (like sodium hydroxide or trisodium phosphate) but not in water, although it disperses easily in cold water and forms a stable dispersion system upon high-speed stirring. Curdlan Gum is used in various food products including flour-based items, instant noodles, tofu, meat, hamburgers, meat substitute foods, and plant-based meat products.
2，Main Source and Safety？
Curdlan Gum is derived from NON-GMO maize and is confirmed to be KOSHER, HALAL, and Vegan. It is considered safe for food use and suitable for vegan products.
3，Properties of Curdlan Gum？
- Hot Gelation: The gel strength of Curdlan increases with temperature, peaking at 130°C.
- Тепловая обратимость: Heated dispersions of Curdlan form an irreversible gel when cooled to 40°C. If heated to 60°C, it can revert to its original dispersion.
- Thermal Irreversibility: Heating above 80°C forms an irreversible gel.
- Film-forming: Curdlan can form films that are water-insoluble, biodegradable, and effective oxygen barriers.
4，Working Principle？
Curdlan Gum functions by gelation, thickening, and stabilization in food products.
5，Applications？
Curdlan Gum E424 is used in a variety of food products including flavor fermentation milk, ice cream, bean curd, fruit jams, soy protein products, gum-based candies, fresh noodles, pre-cooked and marinated meat products, sausages, canned meats, surimi, salad sauces, plant-protein beverages, instant coffee, jellies, meat casing products, and plant-based seafood alternatives.
6，Functions ？
It acts as a stabilizer, gelling agent, and thickener in food preparations.
7，Is Curdlan Gum Gel. Heat Irreversible ?
Yes, gels formed by Curdlan Gum under heating conditions, particularly at around 80°C, are known to be heat irreversible.
This means that once the gel has been formed by heating the Curdlan Gum solution to this temperature, it will not revert back to its liquid state upon subsequent cooling. The irreversible nature of the gel formation is one of the key characteristics that make Curdlan Gum a valuable additive in various food applications, especially where stability under heat is essential.
Это свойство особенно полезно в таких областях применения, как мясные продукты, растительные мясные альтернативы и другие пищевые продукты, требующие стабильности в процессе приготовления или выпечки. Необратимость при нагревании обеспечивает сохранение текстуры, консистенции и целостности геля даже после воздействия на пищевой продукт высоких температур.
