Bulk Citric Acid

What is Citric Acid?

Citric acid is a weak organic acid that is naturally found in citrus fruits. It is a colorless crystalline solid that is soluble in water and has a sour taste. Citric acid is commonly used as a food additive, flavoring agent, and preservative. It is also used in the production of detergents, cosmetics, and pharmaceuticals. Citric acid can be synthesized from various raw materials, including corn and molasses, through a fermentation process. It is often used to add tartness or sourness to foods and beverages, and it can also help to preserve their freshness by inhibiting the growth of bacteria and mold. In addition to its use in the food and beverage industry, citric acid has a number of other uses, including in the cleaning and personal care industries.

Citric Acid Uses

Here is a list of common uses for citric acid:

  1. Food and Beverage: Citric acid is commonly used as a food additive to add tartness or sourness to foods and beverages. It is found in many products, including fruit juices, jams, jellies, candies, and pickles. Citric acid can also be used to preserve the freshness of these products by inhibiting the growth of bacteria and mold.
  2. Cleaning: Citric acid is used in a variety of cleaning products, including descalers and rust removers. It can be effective at removing hard water deposits and mineral build-up.
  3. Personal Care: Citric acid is used in a range of personal care products, including soaps, shampoos, and skin care products. It can help to adjust the pH of these products and can also act as a preservative.
  4. Pharmaceuticals: Citric acid is used in the production of some medications, including effervescent tablets, which are designed to dissolve in water.
  5. Industrial: Citric acid is used in the manufacture of detergents, adhesives, and certain types of plastics. It can also be used in the processing of leather and textiles.
  6. Laboratory: Citric acid is commonly used in laboratory settings as a buffering agent and pH adjuster. It is also used in the production of certain types of buffer solutions.

Wholesale Citric Acid

Citric acid is available for wholesale purchase from a variety of sources, including chemical supply companies and food ingredient distributors. Wholesale prices for citric acid may vary depending on the quantity being purchased, the purity of the product, and the terms of the sale. It is possible to find citric acid for sale in a range of quantities, from small packages to bulk containers. Some suppliers may offer discounts for larger orders or for repeat customers. To find a wholesale supplier of citric acid, you can search online directories, such as ThomasNet or Chemicals.pl, or use a search engine to find local or online suppliers. You can also contact chemical supply companies or food ingredient distributors directly to inquire about their wholesale pricing and availability of citric acid. When purchasing citric acid wholesale, it is important to consider factors such as the supplier’s reputation, the quality of the product, and the terms of the sale. You may want to request a sample or a certificate of analysis to ensure that the citric acid meets your quality standards.

Bulk Citric Acid

Citric acid is available for purchase in bulk quantities from a variety of sources, including chemical supply companies and food ingredient distributors. Bulk citric acid is often sold in large bags or containers, such as drums or super sacks. The price of bulk citric acid may be lower than the price of smaller quantities due to economies of scale. To find a supplier of bulk citric acid, you can search online directories, such as ThomasNet or Chemicals.pl, or use a search engine to find local or online suppliers. You can also contact chemical supply companies or food ingredient distributors directly to inquire about their bulk pricing and availability of citric acid. When purchasing citric acid in bulk, it is important to consider factors such as the supplier’s reputation, the quality of the product, and the terms of the sale. You may want to request a sample or a certificate of analysis to ensure that the citric acid meets your quality standards. In addition to purchasing bulk citric acid from a supplier, it is also possible to synthesize citric acid on a large scale through a fermentation process using raw materials such as corn and molasses. This may be an option for companies that require large quantities of citric acid on a regular basis.  

Citric Acid Synthesis

Citric acid can be synthesized through a fermentation process using raw materials such as corn or molasses. The process involves the cultivation of a microorganism, such as Aspergillus niger, in a nutrient-rich medium. The microorganism converts the raw material into citric acid through a series of chemical reactions. The synthesis of citric acid typically involves the following steps:

  1. Preparation of the fermentation medium: The raw material is mixed with water and other nutrients to form the fermentation medium. The nutrients may include sources of nitrogen, such as ammonium sulfate or urea, and sources of carbon, such as glucose or sucrose. The pH of the medium is adjusted to an optimal level for the growth of the microorganism.
  2. Inoculation: The microorganism is introduced into the fermentation medium. The microorganism may be obtained from a culture collection or may be produced through a seed culture process.
  3. Fermentation: The fermentation process involves the growth and metabolism of the microorganism in the presence of oxygen. The microorganism converts the raw material into citric acid through a series of chemical reactions.
  4. Harvesting: The fermentation process is typically carried out in a fermentation tank or bioreactor. After a certain period of time, the citric acid is harvested from the fermentation medium by filtration or centrifugation.
  5. Purification: The citric acid is then purified through a series of processes, such as crystallization or ion exchange, to remove impurities and other by-products.

Citric acid synthesis requires careful control of the fermentation conditions, such as temperature, pH, and nutrient levels, to ensure optimal yield and purity of the product. The specific process used to synthesize citric acid may vary depending on the raw material and the microorganism being used.
