Application:	Integrated time-series biochemical, transcriptomic, and metabolomic analyses reveal key metabolites and signaling pathways in the liver of the Chinese soft-shelled turtle (Pelodiscus sinensis) against Aeromonas hydrophila infection.: This study uses a combination of biochemical, transcriptomic, and metabolomic approaches to identify critical metabolites and pathways, including those involving citric acid, in the response of the Chinese soft-shelled turtle to bacterial infection (Ji et al., 2024 ). Enhancement of vitamin B(6) production driven by omics analysis combined with fermentation optimization.: The study integrates omics analyses with fermentation strategies to boost vitamin B6 production, identifying citric acid as a pivotal metabolic component in the optimization process (Tian et al., 2024 ).
Disclaimer:	The product is not intended for use as a biocide under global biocide regulations, including but not limited to US EPA′s Federal Insecticide Fungicide and Rodenticide Act, European Biocidal Products Regulation, Canada’s Pest Management Regulatory Agency, Turkey’s Biocidal Products Regulation, Korea’s Consumer Chemical Products and Biocide Safety Management Act (K-BPR) and others.
General description:	Citric acid is an important organic acid that is extensively used in the food industry as a pH control agent, flavor modifier, an antimicrobial agent, a leavening agent and as an antioxidant. The treatment of potato-based foods with a combination of citric acid and glycine in low concentration may reduce the formation of acrylamide with minimal effect on the flavor. Citric acid is also an effective anti-browning agent of food and beverages due to its ability to inhibit the activity of polyphenol oxidase (PPO) enzyme responsible for browning.
