East Extract

East Extract is a flavouring substance derived from yeast. Yeast extract is produced by breaking down yeast cells to release their natural flavour compounds, often through autolysis (using the yeast's own enzymes) or hydrolysis (using added enzymes or acids). The resulting liquid or paste is concentrated to enhance its savoury, umami taste.

Manufacturers add yeast extract to foods primarily to impart or enhance a savoury, meaty, or umami flavour. It is commonly used in processed meats, soups, stocks, sauces, snacks like crisps, and ready meals. Its rich flavour profile makes it a popular ingredient for adding depth and complexity to a wide range of food products.

Yeast extract is not considered a food additive under UK law and therefore does not have an E-number. It is a source of naturally occurring glutamates, which contribute to its savoury taste. While some people are sensitive to high levels of glutamate, yeast extract is generally consumed in typical amounts as part of a balanced diet. Regulatory bodies like the European Food Safety Authority (EFSA) have evaluated flavouring substances, and yeast extract is permitted for use in foods.
