Toxicological Assessment of D-Allulose From a Novel One-Step Fermentation Process Using Genetically Modified <i>Escherichia coli</i>: A 90-Day Dietary Toxicity Study in Rats. [PDF]

J Toxicol
D‐Allulose is a rare monosaccharide structurally similar to D‐fructose, characterized by low caloric content and relatively high sweetness. This study aimed to conduct a 90‐day oral toxicity test to systemically evaluate the potential toxicological effects of D‐allulose produced via a novel one‐step fermentation process using genetically engineered ...

Safety of D-allulose as a novel food pursuant to Regulation (EU) 2015/2283. [PDF]

EFSA J
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on D‐allulose as a novel food (NF) pursuant to Regulation (EU) 2015/2283. During the risk assessment, the Panel identified a number of data gaps, which needed to be addressed by the applicant ...

Reaction Engineering and Comparison of Electroenzymatic and Enzymatic ATP Regeneration Systems

ChemElectroChem, Volume 10, Issue 22, November 14, 2023., 2023
An electrochemically coupled ATP regeneration by pyruvate oxidase and acetate kinase for the phosphorylation of mevalonate was established and expanded by a polyphosphate kinase. The reaction was characterized and compared with other ATP regenerating systems in terms of the phosphate donor properties and biocatalytic metrics.
