Citric Acid

Epoch master® Citric acid (CA), also known as citric acid, with the molecular formula of C ₆ H ₈ O ₇, is an important organic acid, colorless crystal, odorless, with strong acid taste, easily soluble in water, and is an acidity regulator (GB2760-2014) and food additive.

Citric acid is the organic acid with the largest output produced by biochemical methods in the world. Citric acid and salts are one of the pillar products in the fermentation industry, mainly used in the food industry, such as acid flavor agent, solubilizer, buffer, antioxidant, deodorant, flavor enhancer, gelling agent, toner, etc.

In terms of food additives, they are mainly used in carbonated drinks, fruit juice drinks, lactic acid drinks and other cool drinks and pickled products, and their demand varies with the seasonal climate. Citric acid accounts for about 2/3 of the total consumption of acid flavoring agent. Adding citric acid to canned fruits can maintain or improve the flavor of fruits, increase the acidity (lower pH value) of some fruits with low acidity during storage, weaken the heat resistance of microorganisms and inhibit their growth, and prevent bacterial swelling and damage of canned fruits with low acidity. It is easy to harmonize with the fruit taste when citric acid is added to candy as a sour agent. The use of citric acid in gel food, jam and jelly can effectively reduce the negative charge of pectin, so that the hydrogen bond between pectin molecules can bind to gel. When processing canned vegetables, some vegetables show alkaline reaction. Using citric acid as pH regulator can not only play a role in flavoring, but also maintain their quality. Citric acid has the characteristics of chelation and pH value adjustment, so that it can increase the performance of antioxidants, inhibit enzyme activity and extend the shelf life of food in the processing of quick frozen food.
