Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 12: suitability of taxonomic units notified to EFSA until March 2020

open access: yesEFSA Journal, Volume 18, Issue 7, July 2020., 2020
Abstract The qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. It is based on an assessment of the taxonomic identity, the body of knowledge, safety concerns and antimicrobial resistance.

Boosting the Heterologous Expression of d‑Allulose 3‑Epimerase in Bacillus subtilis through Protein Engineering and Catabolite-Responsive Element Box Engineering

open access: yes, 2022
As a natural sweetener with low calories and various physiological activities, d-allulose has drawn worldwide attention. Currently, d-allulose 3-epimerase (DAEase) is mainly used to catalyze the epimerization of d-fructose to d-allulose. Therefore, it is

Efficient Soluble Expression and Fermentation Conditions of D-Allulose 3-Epimerase in Escherichia coli

open access: yesShipin gongye ke-ji, 2022
The DAEase gene sequence derived from Clostridium bolteae ATCCBAA-613 was synthesized by codon optimization. Using pCold TF as the expression vector, the cold-shock promoter CspA induced the expression of the DAEase gene in Escherichia coli BL21(DE3) at ...

Engineering of Acid-Resistant d‑Allulose 3‑Epimerase for Functional Juice Production

open access: yes, 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.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.
