Hitory of citric acid:

Citric acid was first derived from lemon juice by a Swedish researcher in 1784.

The odorless and colorless compound was produced from lemon juice until the early 1900s when researchers discovered that it could also be made from the black mold, Aspergillus niger, which creates citric acid when it feeds on sugar.

Because of its acidic, sour-tasting nature, citric acid is predominantly used as a flavoring and preserving agent — especially in soft drinks and candies.

It’s also used to stabilize or preserve medicines and as a disinfectant against viruses and bacteria.

Citrus fruits and their juices are the best natural sources of citric acid.

In fact, the word citric originates from the Latin word citrus .

Industrial citric acid

Citric acid is the most important organic acid produced in tonnage and is extensively used in food and pharmaceutical industries. It is produced mainly by submerged fermentation using Aspergillus niger or Candida sp.


A large number of micro-organisms including bacteria, fungi and yeasts have been employed to produce industrial citric acid. Most of them, however, are not able to produce commercially acceptable yields. This fact could be explained by the fact that citric acid is a metabolite of energy metabolism and its accumulation rises in appreciable amounts only under conditions of drastic imbalances.

What degree do you need?

Citric acid is present in many degrees, including dehydrated.The dehydrated version is completely dry and is recommended for most applications. There is also a degree of monohydrate that is commonly used in medicinal applications.Citric acid is also available in a variety of grain sizes, including fine grains. It is best used in cosmetics.

How long will you keep your citric acid?

Citric acid has a long shelf life, potentially 5 years or more if stored in ideal storage conditions (dark, dry, weatherproof). However, after only a few months, due to its dehumidifying properties (absorption of moisture from the air), it can start to shrink and cause the seeds to stick to each other. This reduces efficiency, but may make working with citric acid more difficult, as these lumps can be easily crushed into grains.

Examples of citrus fruits include:

  • lemons
  • limes
  • oranges
  • grapefruits
  • tangerines
  • pomelos

Citric acid should avoid from touch or breath

Iranian Citric acid since has PH about 4.8 and corrosive properties, shouldn’t be in touch with skin or eyes straightly and also should avoid to breath because it could lead to some hurt to the body. According to this issue, this acid needed to has standard packing and safe shipment in every type of that.

Other fruits also contain citric acid but in lesser amounts. These include:

  • pineapple
  • strawberries
  • raspberries
  • cranberries
  • cherries
  • tomatoes

While not naturally occurring, citric acid is also a byproduct of cheese, wine, and sourdough bread production.

At room temperature, citric acid is a white crystalline powder. It can exist either in an anhydrous (water-free) form, or as a monohydrate that contains one water molecule for every molecule of citric acid. The anhydrous form crystallizes from hot water, while the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form by heating it above 74°C.

Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15°C.

Chemically, citric acid shares the properties of other carboxylic acids. (organic acids characterized by the presence of a carboxyl group

  • Cheese Manufacturing: – The cheese industry uses citric acid, particularly with mozzarella. It utilizes citric acid as a catalyst to quickly ferment milk. Faster fermentation means large-scale operations can create cheese more rapidly.
  • Shelf Life: Bacteria needs a stable pH to survive. Because citric acid reduces the pH to levels too low for most bacteria, the shelf life of processed foods increases dramatically for jams and jellies, canned foods, meat products, and other foods.
  • Taste: Along with preserving carbonated beverages, teas, and juices, citric acid adds the sour or acidic flavor consumers enjoy.
  • Emulsifier: Citric acid acts as a vegetable fat emulsifier. Because fats are unable to coagulate, ice cream and sherbet retain a consistent texture and flavor throughout.
  • Effervescence: When coupled with sodium bicarbonate, citric acid effervesces. Fizzy candies, carbonated beverages, and powdered drinks, as well as antacid tablets and powders, owe their effervescence to this chemical reaction. In fact, approximately 50% of citric acid production is utilized in beverages.
  • Beer & Wine: Because citric acid is a weak acid, it is often utilized to create an acidic environment in beer and wine production.
  • Absorption: Many common vitamins and minerals work more expediently within an acidic pH environment. Citric acid is used in dietary supplements to accelerate absorption. Also, without citric acid, a vitamin C tablet would taste quite bitter.

Citric acid versus lemon juice


Lemon is one of the richest sources of citric acid in nature, but lemon juice and citric acid are not the same. The difference between citric acid and lemon juice is that citric acid is a concentrated acid compound, while lemon juice contains citric acid, water, vitamin C and other molecules. Lemon juice also has nutritional value, but citric acid lacks nutrients and very few calories.It can be purchased in bulk and has a high durability.

Sell ​​citric acid

One of the most common places to sell citric acid is local grocery stores or supermarket chains. Other options include craft stores.99.9% pure citric acid can be used in a wide range of applications.To Sell ​​citric acid , it can be produced directly for the customer and then sold. Therefore, the best available prices for wholesale can be offered.Over the years, bath bombs (known as bath gases) have become increasingly popular. As a result, the use of this product has become more popular. Today, we see that bath bombs are one of the most commonly used uses to sell citric acid powder.
