Citric Acid Monohydrous and Anhydrous High Purity for Food Additives CAS77-92-9
Product Description
Citric acid is a naturally occurring organic acid that is found in a variety of fruits, including lemons, limes, oranges and certain berries. New Ambition provides Citric acid Monohydrate and Anhydrous in markting.
Citric acid is an integral part of the Krebs cycle and therefore plays an essential role in the metabolism of all living things. It is a relatively weak acid and widely used throughout the food and beverage industry for a variety of purposes as an acidity regulator, preservative, flavor enhancer…etc. It is often used in the production of soda, candy, jams, and jellies, as well as processed foods like frozen and canned fruits and vegetables. Additionally, citric acid is used as a preservative to help extend the shelf life of products by inhibiting the growth of bacteria and other microorganisms.

Function
Citric acid is known as the first edible sour agent, and China GB2760-1996 is the requirement for the allowable use of food acidity regulators. In the food industry, it is widely used as a sour agent, solubilizer, buffer, antioxidant, deodorant and sweetener, and chelating agent, and its specific uses are too numerous to enumerate.
1. Drinks
Citric acid juice is a natural ingredient that not only imparts fruit flavor but also has solubilizing buffering and anti-oxidation effects. It harmonizes and blends sugar, flavor, pigment and other ingredients in beverages to form a harmonious taste and aroma, which can increase resistance. Bactericidal effect of microorganisms.
2. Jams and jellies
Citric acid works in jams and jellies similar to what it does in beverages, adjusting the pH to make the product sour, the pH must be adjusted to be most suitable for a very narrow range of pectin condensation. Depending on the type of pectin, the pH can be limited between 3.0 and 3.4. In the production of jam, it can improve the flavor and prevent the defects of sucrose crystal sand.
3. Candy
Adding citric acid to candy can increase acidity and prevent oxidation of various ingredients and sucrose crystallization. A typical sour candy contains 2% citric acid. The process of boiling sugar and massecuite cooling is to connect acid, coloring, and flavor together. Citric acid produced from pectin can adjust the sour taste of candy and increase gel strength. Anhydrous citric acid is used in chewing gum and powdered foods.
4. Frozen food
Citric acid has the properties of chelating and adjusting pH, which can strengthen the effect of antioxidant and enzyme inactivation, and can more reliably ensure the stability of frozen food.
Application
1. Food industry
Citric acid is the most biochemically produced organic acid in the world. Citric acid and salts are one of the pillar products of the fermentation industry, mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, Deodorizing agent, flavor enhancer, gelling agent, toner, etc.
2. Metal cleaning
It is widely used in detergent production, and its specificity and chelation play a positive role.
3. Fine chemical industry
Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of cutin. It is often used in lotion, cream, shampoo, whitening products, anti-aging products, acne products, etc.
