Citric Acid

 

Citric Acid, or “sour salt,” is a weak, organic acid naturally found in citrus fruits. It is most often used as a natural preservative or to add an acidic or sour taste to food and baked products. Citric Acid can also be used as an emulsifying agent. For example, it is added to some ice creams to keep fats from separating. It is sold commercially as a white, powdery substance.

 

Citric Acid often shows up in baked goods and cake mixes, canned foods and many processed sweets. It is also used in caramels to stop sucrose crystallization. Aside from culinary use, citric acid is also used in cleaning products because it functions as a pH manipulator.

 

How It’s Made

The molecular formula for citric acid is C6H8O7. Traditionally it is derived from fruits such as lemons and limes and makes up to 8 percent of the dry mass of some citrus fruits. Citric acid plays a part of the metabolism of most living things, yet in much smaller quantities.

 

For commercial uses today, citric acid is generally created from feeding sugar (mostly GMO corn syrup) to black mold (Yes, the same black mold you can find in you grandmothers bathroom in the basement). The most commonly used mold is “Aspergillus niger.” Sucrose or glucose, usually from corn starch, is added to the black mold. This creates a citric acid solution, which is filtered out of the mold. The solution is then processed using lime and sulfuric acid. Black mold is a cheap and efficient way to make citric acid on a large scale, processable way (Yes, these big companies are getting more and more rich by feeding us product that comes from BLACK MOLD). 1 

 

Some consumers are pushing back against the more chemical process used to make citric acid, and say GMO products are often used in the production but not labeled. In response, some companies have started producing GMO-free citric acid.

 

But does it really matter? If the company is taking organic corn, processing it and feeding it to black mold to POOP out citric acid, do we really care that the corn was organic? No! Of course not. What is more important is the elephant in the room: Black Mold

 

Where Does It Comes From?

The first records of citric acid are found in the eighth century. However, Carl Wilhelm Scheele first isolated it from lemon juice in 1784. Industrial production took off during the late 19th century. Then in 1893, sugar was discovered as a way to process citric acid. American food chemist James Currie began using mold to produce citric acid in 1917.

 

 

FDA Regulation

There are no limitations or sanctions on citric acid and it is recognized by the FDA as GRAS. It is classified as a preservative or additive.
