Ascorbic acid is the chemical name for vitamin C, this chemical is a natural vitamin that is a powerful antioxidant. Ascorbic acid is normally a clear white or yellow crystal that dissolves well in water.

This powerful antioxidant can have antibacterial properties and can strengthen the immune system.

This mineral is widely found in a variety of vegetables and fruits such as oranges, grapefruits, strawberries, kiwis, and many sweet fruits.

Ascorbic Acid Appearance

This vitamin is very effective for protecting the skin, strengthening bones and healing wounds, strengthening teeth, and repairing tissues. The deficiency of this vitamin in the body causes various diseases such as bleeding gums, feeling exhausted, and weakening of tissues.

The chemical structure of ascorbic acid is as follows:


Chemical structure of Vitamin C

The applications of this food additive in the industry are also very different, this vitamin is used in various industries such as water purification, meat production, and processing, fruit processing, beverages, and production and processing of bread. C6H8O6 is the chemical formula of these chemicals.

The following is more important with the physical and chemical properties and applications of this vitamin.

Physical and chemical properties:

This compound has anticoagulant properties and is easily soluble in water, ethanol, glycerol, and propylene glycol. This vitamin has an acid-like taste, its insoluble in benzene and chlorophyll.

It has a cyclic ester and causes hydrolysis in the aqueous medium to cause acid; That’s why it causes “ascorbic acid”

This powerful antioxidant is used to maintain the smell, color, and quality of food as well as the absorption of oxygen inside the food package to prevent adverse oxidation reactions in the industry.

In some cases, this compound can lower blood pressure and strengthen the body against cancer.

The most important physical and chemical properties of this mineral can be summarized in the following table:

Synthesis and production:

To produce this powerful antioxidant, we use wheat, which is produced by converting starch into glucose, which is then converted to sorbitol. the compound can be combined with acetone at low temperatures, then the product is oxidized with a catalyst, which in this way is a nickel catalyst, acid-washed and then washed, at the end of this process, dried gluconic acid is formed and reacts with hydrochloric to produce crude ascorbic acid.

At the end of the process, operations such as filtration and purification are performed to obtain the desired material.

Applications and uses of Ascorbic Acid:

Before we get acquainted with the most important industrial applications of vitamin C, we want to introduce substances that naturally have this substance in their structure, so that we can provide the vitamin C needed by the body.

Vitamin C is widely found in vegetables such as broccoli, spinach, bell peppers, and red peppers. Fruits such as blackberries, cantaloupe, frankincense, and oranges are also important sources of this vitamin.

Ascorbic Acid in fruits and vegetables

The main use of ascorbic acid is in the food industry. To bake bread, this additive is used to improve the quality of baked bread and reduce bread production time. This substance is usually added to flour or dough.

In the packaging and storage of processed meats, this substance is used as a preservative, which delays the spoilage of the meat and maintains its quality.

Beverage manufacturers use ascorbic acid as a natural additive, its use does not affect the taste of the drink but increases its nutritional value.

This product is also produced in the form of powder or tablets, which is a supplement, taking vitamin C supplements helps the health of skin, hair, and bones.

Water treatment plants use chlorine to kill bacteria from water sources. While this substance is an effective neutralizer of bacteria and makes water safe to drink. Chlorine solution, which is discharged after water treatment, can poison streams and disrupt aquatic life.



Ascorbic acid does not pose much of a risk because it is excreted in water and excreted in the urine. However, at very high doses of this substance, irregular heartbeat, diarrhea, and kidney disease may occur.


Ascorbic acid in a urine test:

When a urine sample contains large amounts of ascorbic acid, blood, glucose, and nitrite reagent pads may not respond well. This interferes especially with low blood pressure measurements.

When the test sample is positive for ascorbic acid, the laboratory may provide a note to the physician with the results indicating possible interferences. A positive test of this material can pose a high risk to a patient’s immunity by losing positive blood in the urine.

This vitamin is a potent antioxidant that can cause false-negative test results detected by the peroxide reaction.

Transporting and storage:

Use a cool and dry place to store this material and keep it away from heat and direct sunlight.
