Ammonium alginate (E403) – what is it?
Ammonium alginate (E403) is an additive used in the food industry, derived from marine algae, mainly from the genus Ascophyllum, Laminaria and Macrocystis. It is the ammonium salt of alginic acid, a natural polymer that is suitable for creating gel-like textures and is valued for its thickening, stabilizing and emulsifying properties.
It is characterized by its high water binding capacity, which makes it indispensable in many food products, where it has the function of increasing viscosity, improving texture and stabilizing emulsions and suspensions.
Properties of ammonium alginate
Ammonium alginate is distinguished by unique properties, such as its ability to form gels in the presence of calcium ions and its high resistance to acids and high temperatures. These properties make it widely used in a variety of food products. It is also biodegradable and considered safe for health, making it a popular choice in organic food production.
Applications of ammonium alginate
Ammonium alginate is used in many food industries, including ice cream, sauces, jams, creams, as well as in bakery and meat products, where it acts as a stabilizer, emulsifier and thickener. It is also used in vegan and vegetarian substitutes for gelatin, as it is a natural product and not derived from animals.
Where to buy ammonium alginate?
Ammonium alginate can be purchased at food industry raw material stores, chemical wholesalers, as well as some well-stocked online stores specializing in food additives. It is available in a variety of forms, including powder and solution, making it easy to use depending on production needs.
Ammonium alginate and its functions in food
In food, ammonium alginate has a number of important functions. It acts as a stabilizer, preventing the delamination of products such as sauces and beverages. As a thickener, it improves the texture and consistency of products such as jams and jellies. In frozen products such as ice cream, it prevents ice crystallization, making them creamier and more uniform. In addition, ammonium alginate is used in the production of edible food packaging, an innovative solution in reducing waste and contributing to the sustainability of the food industry.
