Citric Acid Food Grade

Food-grade Citric Acid is a versatile food additive that can act as an acidifier, solvent, buffer, antioxidant, deodorant, flavorancer, gelling agent, and colorant. It can not only enhance the taste and flavor of food but also inhibit bacterial growth and prevent food discoloration and spoilage. addition, Citric Acid also has a chelating effect, which can remove certain harmful metals.

The role and function of citric acid in food:

Improve the taste: The citric acid additive is an organic acid with a better taste, which can improve the appetite.ropriate addition to food can increase the taste of food and improve the situation of poor appetite.

Preservation and fresh-keeping: The addition of citric acid in canned can maintain or improve the flavor of fruit, improve the acidity (lower pH value) of some fruits with low acidity during canning, weaken the heat resistance of microorgan and inhibit their growth, and prevent the bacterial swelling and damage that often occurs in canned fruit with low acidity.

Regulate pH value: The chelating effect and characteristics of regulating pH value of citric acid make it possible to increase the performance of antioxidants in the processing of quick-frozen food, inhibit enzyme activity and prolong the period of food.

Improve the appetite: The citric acid additive can stimulate the taste buds, promote the secretion of saliva and gastric juice, and has effect of improving the appetite. If the patient has a loss of appetite, he can eat the citric acid additive appropriately before meals, which can help to improve the loss of appetite.

Cleaning mechanism: Citric acid has little corrosion on metal and is a safe cleaning agent. Since citric acid does not contain Cl−, it will not cause stress of equipment. It can complex Fe3 and weaken the promotion of Fe3 on corrosion. Citric acid can dissolve ferric oxide and cupric oxide to form citrate of iron and copper. If ammoniated citric acid solution is used, it can generate citric acid ferrous ammonium and citric acid ferric complexes with very large solility, and the cleaning effect is very good. Citric acid is mainly used to remove rust, so it is mainly used to clean newly built boilers. Citric acid can used to clean calcium and magnesium scale and rust in boilers when it is mixed with aminocaproic acid, glycolic acid or formic acid. Citric can be used to clean superheaters when it is mixed with ethylenediaminetetraacetic acid (EDTA).

Cleaning water dispenser: Use-grade citric acid (powder) to dilute with water, inject it into the water dispenser's heating inner tank, soak for about 20 minutes, and rinse the inner tank repeatedly with clean water until it is clean. It is non-toxic and effective.
