Soya Isolate

Soya isolate is a highly purified form of protein derived from soybeans. It is produced by removing most of the fat and carbohydrates from defatted soy flour, resulting in a powder with a high protein content, typically 90% or more. This process concentrates the soy protein, making it a versatile ingredient.

Soya isolate is primarily used as a protein source and texturiser in a variety of food products. Manufacturers add it to enhance the protein content of foods like plant-based alternatives to meat and dairy, protein bars, and nutritional supplements. Its neutral flavour and ability to bind water also make it useful in baked goods and processed meats.

Soya protein isolate is not classified as a food additive and therefore does not have an E-number or require authorisation on the Register of Food Additive Authorisations. It is a source of complete protein, containing all essential amino acids. The Food Standards Agency (FSA) and Food Standards Scotland (FSS) provide guidance on healthy eating, which includes consuming a balanced diet. International bodies like the WHO have reviewed soy protein's role in diet. Evidence regarding the health effects of soy consumption is extensive, with ongoing research into its benefits and potential impacts.
