Sodium sulphite: bleach and preservative
Sodium sulphite is a salt of sodium and sulphurous acid. The excipient is used for many different purposes and can be found in various industries. For example, it is also used in the paper and pharmaceutical industries. In the food industry it is used as a bleaching agent to preserve the fresh appearance of products as much as possible. It is a white, odourless powder that sinks into water and slowly dissolves. Sodium sulphite has a slightly salty taste. In addition to being a bleach, it is also a preservative. It has been assigned number E-221.
The composition of sodium sulphite
Sodium sulphite is found in crustaceans, sultanas, dried fruit and wine. The latter contains a limited amount of this substance already naturally. It is also used as a bread improver. In the meantime, it may no longer be applied to meat because it masks the brown colour caused by bacterial spoilage. Sodium sulphite composed of sodium and sulphuric acid. The latter component in particular often raises questions. After all, what exactly is sulphurous acid? Sulphuric acid is the acid that is formed after the solution of sulphur dioxide in water. This acid forms the basis for sulphites. Although you may suspect that it is a very strong acid, this is not true. It is many times less strong than sulphuric acid.
