Sodium hydroxide (E524) – what is it?
Sodium hydroxide, also known as caustic soda, is an organic chemical compound with the formula NaOH. As a food additive, it is labeled E524. The substance is strongly alkaline and is used in various manufacturing processes and in the food industry.
The use of sodium hydroxide in the food industry must be strictly controlled, as it is a corrosive substance that can be dangerous in high concentrations. However, when used properly, it has many benefits in food processing, including improving texture and extending the shelf life of products.
Properties of sodium hydroxide
Sodium hydroxide has a strong alkaline effect, which makes it effective in neutralizing acids and in saponification processes. It is a hygroscopic substance, which means that it has the ability to absorb moisture from the environment. This property is used in the food industry to regulate the acidity and moisture content of products.
Applications of sodium hydroxide
E524 is widely used in the food industry, including in the production of olives, in the process of softening them and removing bitter compounds. In addition, it is used to regulate pH in beverages and as a cleaning agent in the food industry, thanks to its strong alkaline properties.
Where to buy sodium hydroxide?
Sodium hydroxide (E524) is available at specialty stores with raw materials for the food industry and online chemical stores. Due to its corrosive properties, purchase requires caution and the manufacturer’s recommendations for safe use should be followed.
Sodium hydroxide and its functions in food
In the food industry, sodium hydroxide (E524) has many important functions. It helps improve the texture and color of some products, such as olives. It is also used to remove the skin from some fruits and vegetables in preparation for further processing. Thanks to its properties, it also enables the effective cleaning and disinfection of equipment and surfaces in production facilities, which contributes to maintaining high hygienic standards in food production.
