Soy preparation

Soy preparation refers to a food ingredient derived from soybeans. Soybeans are legumes native to East Asia, widely cultivated for their edible beans. The preparation can involve various processing methods, such as grinding, pressing, or fermentation, to create different forms like soy flour, soy protein isolate, or textured vegetable protein.

Manufacturers use soy preparations primarily for their protein content and functional properties. They act as a source of plant-based protein in vegetarian and vegan products, and can also serve as emulsifiers, thickeners, or binders in sauces, baked goods, and meat alternatives. Soy preparations are commonly found in vegan cheeses, meat substitutes, and protein-enriched snacks.

Soy preparations are not typically considered food additives and therefore do not have E-numbers or require authorisation on the Register of Food Additive Authorisations. Soy is a source of complete protein and contains various nutrients. Some research suggests potential benefits of soy consumption, such as effects on cholesterol levels, but evidence can be mixed and further research is ongoing.
