Citric acid is readily found in citrus fruits such as oranges and grapefruits, though the highest concentration of citric acid is found in lemons and limes. According to Science Daily, citric acid is used in the kitchen for cooking and as a preservative, in cleaners and also for medicinal purposes. In the kitchen, it is easily procured by squeezing citrus fruits and is also available in liquid, extract and powder forms. Generally, citric acid for medicinal use is commercially prepared and purchased in liquid form. Citric acid is also called sodium citrate.
Kitchen Uses
According to Science Daily, this sour tasting organic acid is commonplace in the kitchen as it is used in foods as a preservative. It is often used in canning to kill botulism and acts as a preservative to prevent foods from turning brown or discoloring. It is also used in making sour candies and to add a touch of tartness to many beverages such as fruit juice and soda.
Household Cleaning Uses
Citric acid is often added to cleaning agents to enhance cleaning power and sometimes to provide a fresh lemon scent to cleaning compounds, especially in the kitchen and bathroom. Citric acid kills microorganisms on contact and polishes as it shines surfaces such as ceramic tile, kitchen counters, floors and the kitchen sink and faucet. It may even be used alone to effectively clean and polish household surfaces for an eco-friendly option to cleaning products. Citric acid, like vinegar, can clean the residue that accumulates in coffee makers.
Medical Uses
Citric acid is also used medicinally in a number of ways, such as the citric acid urine test. In this test, urine is collected for a 24-hour period and used to diagnose numerous conditions, according to MedlinePlus. Elevated levels of citric acid may indicate renal tubular acidosis or kidney stones and also may indicate a high carbohydrate diet, excessive vitamin D or ongoing estrogen therapy. Low citric acid levels may signal acidosis, chronic renal failure, diabetes or hypothyroidism. Other medical uses for citric acid include prevention of gout, kidney stones or metabolic acidosis.
Side Effects
Available as a liquid or a powder and mixed with water or juice, it is possible to experience side effects from taking citric acid such as cramps, muscle twitching, muscle weakness, difficulty breathing, tarry stools, restlessness, severe diarrhea and even seizures. When taking citric acid, it is important to take it on a full stomach, drink plenty of water and to avoid antacids.
