Application of Citric Acid Monohydrate and Citric Acid Anhydrous
Citric acid monohydrate
1. Food industry use:
Acid regulation: Citric acid monohydrate is acidic and is widely used as an acid agent in the food industry.
2. As raw materials:
It is an organic synthetic raw material, used for the production of citric acid mono - and di-acid glycerol esters and citric acid sodium salt, potassium salt, iron salt and so on.
3. Health care use
Promote digestion: Citric acid monohydrate can promote gastrointestinal peristalsis, has the effect of moistening bowel, can be used to improve constipation, indigestion and other symptoms.
Citric Acid Anhydrous
1. Food industry use
Sour agent: As a sour agent, it is widely used in the production of various drinks,
juice, canned food, candy, jam, jelly, so that the sour taste of the product is fresh
and delicious, and has a sweet and fruity taste.
2. Sucrose conversion agent:
Adding an appropriate amount of anhydrous citric acid in sucrose solution can convert it into sugar to improve the saturation and viscosity of sucrose, increase osmotic pressure, effectively prevent sugar products from returning sand, and improve the preservation of products and improve its texture.
3. Loosening agent improvers:
When baking soda is used as a loosening agent in pasta products, the products are often alkaline and have poor taste. If anhydrous citric acid and baking soda are used at the same time, the carbon dioxide generated by baking soda molecules in the reaction process can be absorbed, and the accumulation of sodium carbonate is not caused, thus reducing the alkalinity of pasta and improving the flavor.
4. Buffer:
Vegetables and fruits in the processing due to variety, origin, harvest time, storage time will make their acid content is different, the use of anhydrous citric acid can control the acidity of the solution, ensure product quality, but also can inhibit bacterial growth, reduce sterilization time and reduce sterilization temperature.
5. Other functions:
Anhydrous citric acid can also be used as an antioxidant enhancer, bleach enhancer, jam coagulant, fruit color agent, flavor enhancer and deodorant for fish and goat milk.
Animal breeding industry uses
Feed disinfection and mildew prevention: Adding citric acid to the compound feed can be disinfected, prevent mildew and prevent infection of animal feed. Animal consumption of citric acid can reduce the proliferation of pathogens and the production of toxic metabolites, and improve the stress of animals.
