Sodium Citrate and Citric Acid: Health Benefits and Applications 

In this article, we have explored the basic, chemical, and industrial applications of sodium citrate and citric acid.

What is sodium citrate?

Sodium citrate, or C₆H₅Na₃O₇ is a sodium salt of citric acid. It is highly water soluble, being of an ionic molecular nature and crystallise as a hygroscopic powder. It is white in colour and has a taste of salt, sour that reminds oneself of citric acid. Thanks to its high solubility inherent in this metal, it has a very pronounced chelating tendency that makes it readily react with various other metal elements to form complex bonding compounds. Potassium ion participates in many essential industrial processes and uses in medical procedures.

What is citric acid?

Citric acid (C₆H₈O₇) has three carboxylic acid functional groups in its molecular structure and has a monoclinic crystalline structure. It naturally exists as a colorless, odorless, and tasteless crystalline compound. This compound can be produced naturally or synthetically. Common natural foods are citrus fruits like oranges, grapefruits, etc. In the food industry, you will find that citric acid is produced through the fermentation of microorganisms like fungi. It is frequently used in food and drinks to improve the flavor and give them a citrus taste.

Citric acid is employed in different fields too; it perfects the sop production and happens to be an ingredient during preparations of washing powders, as well as acted within frozen foods where its acidic nature shares efficient slow down action over oxidative enzymes making overall food texture more steady. In some cases, also useful for human body vitamin C supply. Citric acid is popular in the beauty kingdom as well, and it often appears when you use skin care products such as ape masks capable of removing dead cells and brightening skin color.

Applications of Sodium Citrate and Citric Acid Solution:

Both have their benefits and applications, but they are also used together as a solution for various applications. These are:

1.One of the most common uses of sodium citrate and citric acid solutions is their use as emulsifying agents in the food industry. This role is very significant when it comes to the cheese production processes—yes,  the same cheese we use in our pizza. It helps the separation of fats and increases the consistency of cheese.

2.It also finds its way into foods like pickles and other foods we love, like fermented veggies. It gives them an acidic feel and also preserves their taste.

3.it is commonly used as an anticoagulant agent in blood sample tubes and even in various medical devices. Most people don't know that this solution is also used for urine alkalinization due to its strong alkaline properties. It is also used in many human urological studies and procedures requiring the alkanization of biological waste solutions. 

4.Sodium citrate and the citric acid solution are also frequently used in the dialysis process. Doctors nowadays use it as a sequestering agent during the dialysis process, which helps to remove unwanted metal ions and avoid the formation of any calcium deposits.

5.This solution is also widely used in cleaning agents thanks to its strong chelating properties for cleaning and descaling commercially available agents like coffee makers, kettles, etc. 

6.Medical professionals also use it to reduce elevated acid levels, along with its use to treat kidney stones.Not everything is smooth with this solution. You might be impressed by the health applications it has in the medical sector,  but it should be noted that it can cause side effects when consumed. The most common ones reported by people are diarrhea and vomiting.  Such symptoms can be easily avoided by taking it with water or suitable fruit juice, or just taking it with a normal meal.

Wrapping Up:

We can conclude this article by saying that both sodium citrate and citric acid pose significant applications and also have a strong impact in terms of advantages when they are together in a solution. When together, they function by lowering the body's acid production and can also be used in industry to increase the shelf life of foods and much more. It is always advised to use such medications under the supervision of a health professional.
