Propylene glycol alginate (E405)

Propylene glycol alginate (E405) – what is it?

Propylene glycol alginate, also known as E405, is a food additive derived from alginate, a salt of alginic acid, and propylene glycol. It is a substance with unique emulsifying and stabilizing properties, making it a valuable ingredient in the food industry. E405 is considered safe for use as a food additive by the world’s major regulatory bodies.

Propylene glycol alginate is relatively non-toxic and biodegradable, adding to its appeal as a food additive. Thanks to its properties, it can improve the texture, appearance and shelf life of food products.

Properties of propylene glycol alginate

Propylene glycol alginate is characterized by its ability to stabilize emulsions, allowing it to combine ingredients that would not normally combine, such as water and oil. As a result, E405 is used in many food products, including sauces, dressings, beverages and dairy products. It is also used to prevent ice crystallization in frozen desserts and as a thickening and stabilizing agent in bakery and confectionery products.

Uses of propylene glycol alginate

Propylene glycol alginate is widely used in the food industry. It can be found in products such as ice cream, sauces, dressings, beverages, dairy products and in many types of ready meals. Its use helps maintain the consistency of products, prevents them from delaminating and extends their shelf life.

Where to buy propylene glycol alginate?

Propylene glycol alginate is mainly available to food manufacturers and food professionals. It can be purchased through specialized food industry raw material suppliers, both in stationary stores and online. Individuals interested in experimenting with E405 in the home kitchen can look for it in online stores offering food additives for culinary hobbyists, or in stores specializing in selling raw materials for home food production.

Propylene glycol alginate and its functions in food

As a food additive, propylene glycol alginate has several important functions. First of all, it acts as an emulsifier, combining ingredients that would not naturally come together, and a stabilizer, preventing the product from delaminating. It also helps improve the texture of food products, giving them the desired consistency and protecting them from water loss. In addition, E405 can be used to control the crystallization of ice, which is particularly important in the production of ice cream and frozen desserts.
