| Content | Citric acid is a weakorganic acid. 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.
Used in food, beverage industries as acidulous agent, flavoring Used in food, beverage industries as acidulous agent, flavoring agent, and preservative, also used in detergent, electric plating, and chemical industries as oxidation inhibitor, plasticizer etc.
Citric acid is an organic acid found a variety of fruits and Acidity regulators vegetables, but it is most concentrated in lemons and limes. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle or Krebs cycle (see last paragraph) and therefore occurs in the metabolism of almost all living things. Excess citric acid is readily metabolized and eliminated from the body. Citric acid is an antioxidant. It is also used as an environmentally friendly cleaning agent.

| Sodium Diacetate is a molecular compound of acetic acid and sodium acetate. According to a patent, free acetic acid is built into the crystal lattice of neutral sodium acetate. The acid is firmly held as is evident from the negligible odor of the product. In solution it is split off into its constituents acetic acid and sodium acetate. As a buffering agent, sodium diacetate is applied in meat products to control their acidity. Apart from that, sodium diacetate inhibits the growth of various microorganisms usually found in meat products, thus it can be used as a preservative and safeguard for food safety and shelf life extension. Moreover, sodium diacetate can be used as a flavoring agent, applied as a powdered seasoning, to impart a vinegar taste to meat products.

| Gum Arabic, also known as Acacia Gum, chaar gund, char goond, or meska, is a natural gum made of hardened sap taken from two species of the acacia tree; Acacia senegal and Acacia seyal. The gum is harvested commercially from wild trees throughout the Sahel from Senegal and Sudan to Somalia, although it has been historically cultivated in Arabia and West Asia.
Gum Arabic is a complex mixture of glycoProteins and polysaccharides. It was historically the source of the sugars arabinose and ribose, both of which were first discovered and isolated from it, and are named for it.
Gum arabic is used primarily in the food industry as a stabilizer. It is edible and has E number E414. Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries, although less expensive materials compete with it for many of these roles.
While gum arabic is now produced mostly throughout the African Sahel, it is still harvested and used in the Middle East. For example, Arab populations use the natural gum to make a chilled, sweetened, and flavored gelato-like dessert.

| Propylene glycol alginate or PGA is an additive used mainly as a thickening agent in certain types of food. It is made from the kelp plant or from certain kinds of algae, which is processed and transformed into a yellowish, grainy chemical powder. The powder is then added to foods that require thickening. Propylene glycol alginate has been used for many years as a food preservative. Many food manufacturing companies use it in the most common household food items. Most types of gel-like foods, including yogurt, jellies and jams, ice cream, and salad dressing contain propylene glycol alginate. Certain condiments and chewing gum also contain this chemical. Some kinds of cosmetics used on the skin use this chemical as an ingredient to thicken or preserve a make-up product.

Also known as milk acid, is a chemical compound that plays a role in several biochemical processes.
In animals, L-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise. It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal which is governed by a number of factors including: Monocarboxylate transporters, concentration and isoform of LDH and oxidative capacity of tissues. The concentration of blood lactate is usually 1-2 mmol/L at rest, but can rise to over 20 mmol/L during intense exertion. Industrially, Lactic Acid fermentation is performed by Lactobacillus bacteria, among others. These bacteria can operate in the mouth; The acid they produce is responsible for the tooth decay known as caries. In medicine, lactate is one of the main components of Ringer's lactate or lactated Ringer's solution (Compound Sodium Lactate or Hartmann's Solution in the UK). This intravenous fluid consists of sodium and potassium cations, with lactate and chloride anions, in solution with distilled water in concentration so as to be isotonic compared to human blood. It is most commonly used for fluid resuscitation after blood loss due to trauma, surgery, or a burn injury.
