title: Plant bioreactors - the taste of sweet success.
abstract: Thaumatins are intensely sweet proteins (3000 times sweeter than the same weight of sucrose) that are found in the arils of the tropical perennial plant Thaumatococcus daniellii Benth and are produced commercially by aqueous extraction from the fruits. The proteins are widely used as sweeteners and flavor enhancers in the food industry, and the European Food Safety Association (EFSA) has recently confirmed that their use as feed additive (1 to 5 mg/kg complete feed) is safe for all animal species. Given the large market for sweeteners and flavor enhancers, thaumatins could become increasingly important in the food and feed additives sector. In this issue of Biotechnology Journal, a study examines the production of thaumatin in tobacco hairy root cultures.
