The cycle that citric acid undergoes in the human body is called the Krebs cycle, named after Hans Adolf Krebs, who received a Nobel Prize in Physiology or Medicine for its discovery in 1953. It actually refers to the physiological oxidation of fats, proteins and carbohydrates into carbon dioxide and water. During this cycle, eight enzymes help produce energy through aerobic respiration. Citric acid is an alkalising agent. Despite being an acid since most people will say you can’t be alkalinizing if your an acid which is not true. It is able to decrease the level of acidity in body fluids. It can bind with excess calcium and allow it to leave the body. Despite its many health benefits, you should not take citric acid without first consulting your physician.
A Natural Medicine
Citric acid is both a natural and an artificially obtained acid. It is found naturally in every living being: plant (conifer, tobacco leaf) or animal, as in the human tissues and body fluids. In addition, it is present in a large variety of fruits (lemons, limes, oranges, grapefruits, kiwis, strawberries, apples, pears, cherries and raspberries) and vegetables (mushrooms, potatoes, tomatoes, peas and asparagus). Citric acid was first artificially produced in 1784 from lemon juice, by Karl Wilhelm Scheele. It can also be obtained through bio-technology processes for industrial purposes by fermenting the citrus glucose (sugary substance), sucrose or molasses (syrup by-product of sugar cane) in combination with the fungus called “Aspergillus niger.”
What It Is Used For
Citric acid is used for its health benefits and as in food, alcohol and insecticide production. It is the most frequently used preservative in the world today. The lemon salt has been used for centuries to conserve meat and fish. It increases the acidity of the bacterial environment, making it difficult for it and the microbes to survive and, most importantly, to reproduce. It is called lemon salt because it was first extracted from a lemon. It looks like a semi-transparent salt and it has no odour. It has a sour, acid taste.
- Kidney Stones: Administered while drinking lemonade, citric acid prevents the formation of kidney stones and ensures proper functioning of the kidneys. Citric acid’s ability to chelate calcium and its alkalising properties make it useful as a method for preventing kidney stones.
- Anti-oxidant: As an anti-oxidant, citric acid may be able to neutralize the damaging effects of free radicals, unstable compounds that can accumulate in the body and can trigger the growth of cancerous tumours.
- Mineral absorption: Specialists say that the citric acid associates itself with minerals and metals easily, a trait which accelerates their absorption into the body.
- Skin Care: Citric acid is a common ingredient found in face packs and skin products. It is considered an antioxidant that can help the regeneration of skin tissue and slowing down the ageing process.
- Skin Colour: In the case of stained skin or freckles, the use of a cream rich in citric acid will have a de-pigmentation effect.
- Sore Throat: Citric acid is of great help when a person has tonsillitis. Gargling with a combination of citric acid and water will clear the infection from the throat because it effectively kills the germs that are causing the infection.
- Nausea: Citric acid can quickly and effectively reduce nausea by reducing the gastric acidity.
Despite its many health benefits, it is important that you avoid citric acid without first consulting a doctor. Citric acid supplementation can cause a variety of side effects, including vomiting, diarrhoea, nausea and abdominal pain.
- Flavour: Citric acid provides flavour to aliments, sweets and to soft drinks and alcoholic drinks.
- Food Production: It strengthens the gelatin in jams and slows down the oxidation process in fruits and fruit products, by combining itself with the naturally present metals and preventing their discolouration. Citric acid is often used for creating the proper environment for the enzyme activity in the process of cheese making. It can also be used for making ice cream because it helps the fat cells in dairy separate.
- Pest Control: Citric acid is known to have the ability to destroy bacteria, mould, viruses and rust, and therefore was used in the production of pesticides, fungicides and disinfectants solutions.
- Alcohol Production: Sometimes, citric acid is added to wine, if the grapes used have low acidity to improve the taste. When manufacturing beer, citric acid reduces the sugar loss from the barley as it germinates. Therefore, more of the sugar turns to alcohol, and beer production is optimized.
- Drugs: Citric acid is used in the manufacture of medicinal products and in bio-technology industries. It is combined with sodium bicarbonate for medicines such as Alka-Seltzer.
