Citric acid is an organic tricarboxylic acid which is an important metabolite in all animals and plants. Citric acidis a weak organic acid that has the chemical formula C6H8O7. 99% of citric acid is made viamicrobial fermentation. Only 1 percent is naturally derived from citrus fruit.
In biochemistry, citric acid is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. Citric acid is an important metabolite in the pathway of all aerobic organisms. Citric acid protects the brain due to itsantibiotic and anti-inflammatory properties. Citric acid is linked to improved nutrient absorption, and has been tied to improved bone health.
Citric acid has a role as a food acidity regulator, achelator, an antimicrobial agent and a fundamental metabolite. Citric acid, a colorless crystalline organic compound belonging to the family of carboxylic acids, present in practically all plants and in many animal tissues and fluids. It is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.
Citric Acid is a conjugate acid of a citrate(1-) and a citrate anion. More than two million tons of citric acid are manufactured every year. It is used widely as an acidifier, as a flavoring and chelating agent. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution.
What is Sodium Citrate?
Sodium citrate is the sodium salt of citric acid. It is white, crystalline powder or white, granular crystals, slightly deliquescent in moist air, freely soluble in water, practically insoluble in alcohol. Like citric acid, it has a sour taste. From the medical point of view, it is used as alkalinizing agent. It works by neutralizing excess acid in the blood and urine. It has been indicated for the treatment of metabolic acidosis.

You can purchase bath bombs at Target. Bath bombs were invented in 1989 by Lush Cosmetics co-founder Mo Constantine. They are hard-packed mixtures of dry ingredients which effervesce when wet. They are used to add essential oils, scent, bubbles or color to bathwater.
How Citric Acid Powder Is Used In Food And Drink Products In The USA
Because citric acid is one of the stronger edible acids, the dominant use of citric acid is as aflavoring and preservative in food and beverages, especially soft drinks and candies. In the United States the purity requirements for citric acid as a food additive are defined by the Food Chemicals Codex, which is published by the United States Pharmacopoeia (USP). Citric acid can be added to ice cream as an emulsifying agent to keep fats from separating, to caramel to prevent sucrose crystallization, or in recipes in place of fresh lemon juice.
Citric acid sold in a dry powdered form is commonly sold in markets and groceries as "sour salt", due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed. Citric acid can be used in food coloring to balance the pH level of a normally basic dye. Citric acid has many uses in the food industry as a flavoring agent, pH modifier, and preservative.
Other Uses Of Citric Acid
It is also used as an anticoagulant and antioxidant, and in mineral supplements as citrate salts of metals. It also finds uses in household cleaning solutions, as a pH buffer and as a water softener. Citric acid is used with sodium bicarbonate in a wide range of effervescent formulae, both for ingestion (e.g., powders and tablets) and for personal care (e.g., bath salts, bath bombs, and cleaning of grease).
Commercial Uses Of Citric Acid
More than half of all the citric acid produced is used in soft drinks and other beverages, where it boosts flavors and adds a slightly sour taste. Citric acid also acts as a preservative and flavor enhancer in foods, including jams, gelatins, candies, frozen foods, canned vegetables and meat products.
For canning foods at home, citric acid is a good additive to prevent bacterial growth. It also binds with minerals, making citric acid useful in several commercial applications. For example, your body absorbs minerals in supplements more readily when they're attached to citric acid. As a cleaning product additive, it binds with minerals in hard water, which improves the effectiveness of the soaps and detergents.
Medical Uses Of Citric Acid
Citric acid binds with calcium in your blood, which results in less calcium available to make kidney stones. If you have a history of calcium oxalate kidney stones, consuming plenty of citrus fruits or lemonade helps prevent stones from forming in the future. Citric acid may also break up small stones that are just beginning to form, and it lowers the level of acidity in your urine, which inhibits the development of calcium oxalate and uric acid stones, according to NYU Langone Medical Center.
Health Benefits Of Citric Acid
There are benefits to consuming foods that contain naturally occurring citric acid (from, say, lemon or lime juice) because it acts as an antioxidant, meaning it protects the body from damaging free radicals. Eating ample antioxidants helps with everything from heart health to cancer prevention. Citric acid might find utility in treatment of toxic and inflammatory conditions of the brain and liver tissues.
Where Citric Acid Comes From
Every time you enjoy citrus fruits, you consume citric acid produced by nature. Your body makes its own supply because citric acid is essential for producing the energy that keeps you active and healthy. Commercially produced citric acid is added to foods, beverages and pharmaceutical products, but this type of citric acid comes from yet another source, fermented fungi.
How to Make Citric Acid
