How to Incorporate Citric Acid Into Your Diet

Also known as "sour salt," citric acid is naturally found in citrus fruits, as well as other fruits and vegetables. This organic acid is found at the highest concentration level in fruits such as lemon and limes. Some levels of concentration, although not as high, are also found in oranges and grapefruits. The main factor regarding the acid or acidic value of fruit or vegetables is often related to the conditions surrounding the growth of the fruit.

Apart from being naturally present in fruits and vegetables such as lemon and limes, citric acid can also be produced in powder form for preservation purposes. It can also be used to add acid flavours to food and drinks, either those manufactured by a company or those that you make at home. It is believed that at least 70 per cent of these types of acids are used for beverages or food-related purposes.


Many people use this "sour salt" when making, preserving, or canning different products. From sausages to the first occupants and wheat bread, sour salt can help create additional tart flavours needed in many foods. For canning purposes, lemon will prevent the fruit from darkening over time. It can even be used in household cleaners, like detergents, to help remove soap scum from dishes, showers, and more.

Citric acid is often purchased for home use for many reasons listed above. When stored at room temperature, it will maintain the form of crystallization. This type of acid can be created in either a water-free form (anhydrous) that crystallizes from hot water or can become crystallized with the assistance of cold water (monohydrate). However, by the time many people purchase the product, it is already in a crystalline powder form.
