Product Description

Food-grade citric acid is an important food additive, widely used in acidity regulation, preservation, flavor enhancement and other aspects of food and beverages. Its production process has evolved from natural sources to modern fermentation technology. The following are the main sources of citric acid.

1. Natural sources
Citric acid is a naturally occurring organic acid, widely found in citrus fruits, berries, apples and other fruits, especially lemons and oranges. The natural source of citric acid makes it well accepted by consumers, and many people think it is a "natural" and "safe" additive. In addition to fruits, citric acid can also be extracted from some plants such as citrus, tomatoes, etc.

However, due to the complex extraction process, high cost and limited output of natural citric acid, modern industrial production mainly uses fermentation to produce citric acid.

2. Fermentation method (modern industrial production)
The production of modern food-grade citric acid mainly adopts microbial fermentation, which is economical, efficient, highly controllable, and can produce citric acid in large quantities. The basic process of fermentation is as follows:

a. Raw material selection: The raw materials for the production of citric acid by fermentation usually include sugar substances, such as corn sugar, glucose, cane sugar, etc. Sugar is the main energy source for microbial growth and fermentation, so sugar can be converted into citric acid through fermentation.

b. Fermentation strain: The key to producing citric acid by fermentation is to select the right fermentation strain. Commonly used fermentation strains are Aspergillus (such as Aspergillus niger and Aspergillus kawaguchii), which can efficiently convert carbon sources into citric acid. In modern industry, these strains are genetically optimized and selected to make the fermentation process more efficient.

c. Fermentation process: Under suitable temperature (usually 25°C to 30°C) and pH environment, the selected microbial strain will ferment with the help of sugar to produce citric acid. The entire fermentation process usually takes several days.

d. Separation and extraction: After fermentation, the fermentation broth contains a large amount of citric acid. Through a multi-step separation and extraction process, filtration and precipitation are first used to remove impurities, and then ion exchange, solvent extraction and other technologies are used to separate citric acid from the liquid.

e. Crystallization and purification: Finally, citric acid is crystallized from the solution by evaporation, crystallization and other methods, and then dried to obtain a high-purity citric acid product. The purity of food-grade citric acid is generally above 99.5%, ensuring its safety and stability in food applications.
