Citric acid

Overview

Citric acid is an important organic weak acid, colorless crystal, odorless, soluble in water, the solution is acidic. In biochemistry, it is an intermediate in the citric acid cycle (tricarboxylic acid cycle), which occurs in the metabolism of all aerobic organisms. Citric acid is widely used as an acidity regulator, flavoring agent and chelating agent.

Application
Food industry
1. Soy sauce and jam
– As a sour agent, solubilizer, buffer, etc., improve flavor, promote sucrose conversion, inhibit bacteria, and protect color
2. Carbonated drinks, juice drinks, lactic acid drinks
– As an acid agent, maintain or improve fruit flavor, increase acidity, inhibit microbial growth, and prevent pot swelling
3. Candy
– As a sour agent, easy to harmonize with fruit
4. Gel foods
– Acts as an acid agent to make pectin gel
5. Processed canned vegetables
– Acts as a pH regulator to maintain quality

Chemicals and textiles
1. Reagents for chemical analysis
– Used as experimental reagent, complexing agent, masking agent; Prepare buffer solution
2. Shampoo aid
– Improve the performance of washing products, precipitate metal ions, disperse dirt, and improve the performance of surfactants
3. Formaldehyde-free anti-wrinkle finishing agent
– Made of formaldehyde-free anti-wrinkle finishing agent, used for cotton fabric anti-wrinkle finishing

Livestock production
– Citric acid is added to piglet feed to improve feed utilization and sow litter yield. Rare earth citrate is used in a variety of animals to promote growth, improve product quality, improve disease resistance and feed conversion
