Food Additive Standards

Food additives are substances added to food to maintain or improve its safety, freshness, taste, texture, or appearance. All food additives used in food undergo a safety assessment, which includes rigorous testing, before they are approved, so all food additives are generally recognized as safe substances.

Furthermore, deletion of either the gene encoding the histidine kinase or the response regulator of the TC system resulted in the loss of the ability to grow on (S)-2-Hydroxysuccinic acid, thus indicating that the cognate TC system regulates and is essential for the expression of ME. Transcriptional analyses shows that expression of maeE is induced in the presence of (S)-2-Hydroxysuccinic acid and repressed by glucose, whereas TC system expression is induced by (S)-2-Hydroxysuccinic acid and is not repressed by glucose.
