Food manufacturing processes and technical data used in the exposure assessment of food enzymes
EFSA Journal, Volume 21, Issue 7, July 2023., 2023 Abstract Food enzymes are used for technical purposes in the production of food ingredients or foods‐as‐consumed. In the European Union, the safety of a food enzyme is evaluated by EFSA on the basis of a technical dossier provided by an applicant. Dietary exposure is an integral part of the risk assessment of food enzymes.

ChemCatChem, Volume 12, Issue 8, Page 2245-2252, April 20, 2020., 2020 Different immobilization methods were evaluated for application of two biocatalysts in a cofactor dependent reaction. Promising immobilization and activity yields were obtained by covalent immobilization on synthesized hydrophilic silica particles. High reaction stabilities for the two immobilized enzymes resulted in a 10‐fold increase of the turnover ...

Engineering of Acid-Resistant d‑Allulose 3‑Epimerase for Functional Juice Production
, 2022 d-Allulose, a rare sugar and functional sweetener, can be biosynthesized by d-allulose 3-isomerase (DAE). However, most of the reported DAEs exhibit poor resistance under acidic conditions, which severely limited their application.
