Folic Acid can be used as a health food additive to be added in infant milk powder.
The role of feed grade folic acid is to increase the number of live animals and the amount of lactation. The role of folic acid in broiler feed is to promote weight gain and feed intake. Folic acid is one of the B vitamins, which promotes the maturation of young cells in the bone marrow, promotes growth and promotes the formation of hematopoietic factors. Folic acid has the function of promoting ovulation and increasing the number of follicles. The addition of folic acid to the sow feed is beneficial to increase the birth rate. The addition of folic acid to the laying hens can increase the egg production rate.

It is a natural preservative conservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle, and therefore occurs in the metabolism of virtually all living things.
It is Colorless or white crystalline powder and mainly used as an acidulant, flavorant and preservative preservative in foods and beverages. It is also used as an antioxidant, plasticizer and detergent, builder.
Mainly used in the food , beverage trade as the sour flavour agent, flavoring agent, antiseptic as well as antistaling agent
1. In the food industry, Citric Acid Monohydrate uses as the drinks sour flavour agent. Mainly used in various kinds of cold drinks and for such foods production as soda, candy, biscuit, can, jam, fruit juice ,etc., also can be used as greases antioxidant;
2. In medical industry,Citric acid monohydrate is the raw materials of a lot of pharmaceuticals, such as the citric acid piperazine(lumbricide ), ferric ammonium citrate (blood tonic ), sodium citrate (blood transfusion pharmaceutical). In addition, citric acid also is used as the acidifier in many pharmaceuticals;
3. In the chemical industry, the ester of citric acid can use as the Acidity regulators to make the plastic film of food packing ;
4. In other respects, such as used in industry and civil detergent as the auxiliary agent for making nuisance free detergent; Used in the concrete as the retarder; also been widely used in electroplating, leather industry, printing ink, blue print industry,etc.

It interferes with their ability to make energy. And used in medicine, tobacco, printing and dyeing.
Sodium benzoate is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is used most prevalently in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments. It is also found in alcohol-based mouthwash and silver polish. It can also be found in cough syrups like Robitussin. Sodium benzoate is declared on a product label as sodium benzoate. It is also used in fireworks as a fuel in whistle mix, a powder which emits a whistling noise when compressed into a tube and ignited.
