China Food Acidulant Citric Acid Assay 99% Manufacturer, Factory

Citric acid is a weak organic acid naturally found in citrus fruits. It was first isolated from lemon juice by Swedish chemist Carl Wilhelm Scheele in the 18th century. Citric acid appears as colorless crystals or a white crystalline powder with a strong sour flavor.

In nature, citric acid is widely distributed in various fruits, including citrus, hawthorn, and pineapple. It is also an important intermediate in the tricarboxylic acid cycle in organisms and plays a key role in energy metabolism.

Due to its excellent safety and functionality, citric acid is widely used in various fields, including food and beverages, medicine, daily chemicals, and industry. It serves as an acidulant, pH adjuster, chelating agent, and preservative.

Application

Acidity Regulator

Citric acid can provide a refreshing sour flavor to foods and beverages, improving their taste. It is commonly used in juice drinks, carbonated beverages, candies, jams, and more.

Preservatives and Preservation

Citric acid can lower the pH of foods, inhibit microbial growth, and extend their shelf life. It is often used with antioxidants or preservatives.

Antioxidant & Stabilizing Agents

Citric acid can complex with metal ions, preventing fat oxidation in foods and maintaining color and flavor stability. It is suitable for canned foods, juices, and dairy products.

Food Processing

In candy, jelly, and dairy processing, citric acid can regulate gel formation or emulsification, helping to improve the texture and mouthfeel of the product.

Leaving Agent

In baking, citric acid reacts with sodium bicarbonate to produce carbon dioxide, which acts as a leavening agent and is used in cakes and biscuits.
