一般描述

柠檬酸是一种重要的有机酸,广泛用于食品工业,作为pH调节剂、调味剂、抗菌剂、膨松剂和抗氧化剂。 用低浓度的柠檬酸和甘氨酸混合物处理马铃薯类食品,可以减少丙烯酰胺的形成,并且对风味的影响极小。 柠檬酸也是食品和饮料的有效抗褐变剂,因为它能够抑制引起褐变的多酚氧化酶(PPO)的活性。

应用


  • 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).
