It is a weak organic acid
Citric acid is a weak organic acid that occurs naturally in produce, such as citrus fruits. It is a naturally occurring antioxidant and has a pH level of between 3 and 6 on the pH scale, which ranges from 0 to 14. Its acidic pH means it can kill any bacteria or viruses that cannot survive within this pH range, such as the human norovirus.
Citric acid is commonly used in food preservation, cleaning products, and skincare. It acts as a preservative in many processed foods, preventing the formation of bacteria, mould, yeast, and fungus. It is also added to canned and jarred foods to prevent botulism. Citric acid is used in commercial cleaning products as it can help remove hard water build-up and stains.
Citric acid is also used in the cosmetic industry, where it is an ingredient in various personal care products. It can help brighten skin, correct dark spots, and minimise fine lines. Citric acid can be formulated for use near the eyes, lips, mouth, and nasal passages, as well as for safe application to babies' skin. It is also used in hairsprays, deodorants, body sprays, and soap.
Citric acid is generally recognized as safe (GRAS) as a direct food additive by the U.S. Food and Drug Administration (FDA). However, excessive consumption of citric acid may cause tooth enamel to dissolve over time. Therefore, it is recommended to consume foods containing citric acid in moderation and to rinse the mouth after eating or drinking products containing citric acid.

It is used as a natural preservative
Citric acid is a natural preservative that is safe and non-harmful to humans. It is used to keep food fresh and prevent foodborne illnesses such as botulism, which is found in canned foods that are low in acid. Citric acid is also used in cosmetics and personal care products to preserve colour and fragrance compounds, as well as brighten skin, correct dark spots, and minimise fine lines. In addition, citric acid is a common ingredient in cleaning products, insecticides, and disinfectants due to its ability to destroy bacteria and viruses.
Citric acid is favoured in the food industry for its safe and long-lasting qualities. It is used in packaged, processed, jarred, and canned food to extend shelf life and maintain the original colour and freshness of the product. Citric acid is also added to ice cream to prevent it from separating and to caramel to prevent crystallisation.
Citric acid is naturally concentrated in a variety of fruits and vegetables, particularly lemons and limes. It can also be produced through microbial fermentation using a fungus named Aspergillus niger. This process is environmentally friendly and yields much more product at a lower cost.
Citric acid has been used as a preservative for a long time, being one of the very first natural preservatives to be discovered. It is favoured for its multifaceted properties, such as its ability to act as an emulsifying agent, pH adjuster, clarifying agent, and water softener. These properties make citric acid a staple ingredient in high-production companies that require a safe and effective preservative.
In addition to its preservative properties, citric acid is also used for its protective effects in the body. It can be found in medicines to kill bacteria and lower acid levels in the urine, which is often the aim of kidney medications. Citric acid also has antibacterial properties that can help prevent infections on the skin's surface, making it useful for treating common skin issues in people with diabetes, the elderly, and smokers. Overall, citric acid is a valuable and versatile natural preservative with a wide range of applications in the food, cosmetic, and medical industries.

Citric acid is a weak organic acid that naturally occurs in several fruits and vegetables, especially citrus fruits like lemons and limes. It is widely used in the food and beverage industry to impart a tangy, acidic taste to various products.
In food products, citric acid is added to ice cream to act as an emulsifying agent, preventing the separation of fats and the formation of crystals. It is also used in caramels to prevent sucrose crystallization and in recipes as a substitute for lemon juice. Citric acid is an essential ingredient in the production of certain types of cheese, such as mozzarella and ricotta, where it serves as the main ripening agent.
In beverages, citric acid is commonly used in wine production, particularly when working with fruits that have low natural acidity. It is also one of the acids employed by home brewers to adjust the water chemistry for making beer.
Citric acid is appreciated by cooks and bakers alike for its ability to enhance flavours and create sour treats. It can be added to homemade gummy bears, sourdough bread, and salad dressings, resulting in a more pronounced and balanced taste profile.
When purchasing citric acid, it is important to choose a product that is pure and free from common allergens and gluten. Several brands offer citric acid that is certified gluten-free, non-GMO, vegan, and Kosher, ensuring that it meets a variety of dietary requirements and can be safely consumed by those with gluten sensitivities or celiac disease.

It is used in the production of wine and beer
Citric acid is used in the production of wine and beer. In wine, citric acid is added to increase acidity, complement a specific flavour, or prevent ferric hazes. It is also used to prevent the formation of the white precipitate (FePO4-2H2O) caused by excess iron in wine. Citric acid is added to finished wines to increase acidity and give a "fresh" flavour. Citric acid is also used to neutralise surfaces treated with basic substances and has antimicrobial activity against some moulds and bacteria.
Citric acid is only present in small amounts in grapes, unless it is added. It is one of the fixed acids found in wine grapes, along with tartaric and malic acids. The concentration varies depending on the grape variety and the soil content of the vineyard. The most important of these acids in winemaking is tartaric acid, due to its role in maintaining chemical stability and influencing the taste and colour of the wine.
Citric acid is also used in beer brewing, particularly in the removal of "beer-stone" from fermentation vessels.
