Feature:
Citric acid is a naturally occurring organic acid that is found in a variety of fruits, including lemons, limes, oranges and certain berries. we provides Citric acid Monohydrate and Anhydrous in markting.
Citric acid plays an essential role in the metabolism of all living things. It is a relatively weak acid and widely used throughout the food and beverage industry for a variety of purposes as an acidity regulator, preservative, flavor enhancer…etc. It is often used in the production of soda, candy, jams, and jellies, as well as processed foods like frozen and canned fruits and vegetables. Additionally, citric acid is used as a preservative to help extend the shelf life of products by inhibiting the growth of bacteria and other microorganisms.
Not only in food industry, Citric acid is also used as an antioxidant, plasticizer and detergent in the chemical industry, cosmetics industry and washing industry.
Citric acid is a very essential food additive (used mainly as an acidity regulator), obtained from processing corn into corn sugars into Citric acid.
Storage:
stored for 24 months from the date of manufacture in the un-opened original container. A relative humidity of 50% and a temperature range of 10-35ºC are the most suitable conditions for storage to prevent Citric Acid from crystallization.
- Keep in cool, dry and ventilated place, away from light.
- Avoid mixing with poisonous, peculiar smell and colored powder.
