Soy

Soy, also known as soya, is a legume native to East Asia. It is a versatile crop grown for its edible beans, which are processed into a wide range of food products. The beans are typically harvested, dried, and then processed through methods like crushing, grinding, and extraction.

Soy is widely used as a source of protein and oil in food manufacturing. It functions as an emulsifier, helping to blend oil and water in products like mayonnaise and dressings. Soy is also used to create plant-based alternatives to meat and dairy products, and as a flavour enhancer in savoury dishes.

Soy is a common food ingredient and is not considered a food additive under UK law. It is a source of protein, fibre, and various micronutrients. Some research suggests that consuming soy products may have a beneficial effect on cardiovascular health, although evidence is mixed. Regulatory bodies like EFSA have evaluated soy and its components, with no specific numeric limits set for general consumption. Soy is a common allergen, and UK law requires it to be declared on food labels when present in a food product.
