What You'll Learn
Citric acid is a natural preservative
Citric acid is a versatile additive and preservative in food products, including canned and jarred foods, where it helps maintain freshness over extended periods. It is also added to fresh-cut produce, such as sliced apples, to prevent browning. Additionally, citric acid can be used as a flavouring agent, adding a sour or bitter taste to foods and drinks.
In the pharmaceutical industry, citric acid is used as a preservative and stabilizer for medicines, helping to maintain the integrity of active ingredients. It is also added to mineral supplements, such as magnesium and calcium, to enhance absorption. Furthermore, citric acid exhibits antioxidant, alkalizing, and anti-inflammatory properties, contributing to its use in skincare and anti-aging formulations.
Citric acid is also valued for its disinfectant properties, making it a safer alternative to conventional cleaning agents. It effectively removes soap scum, hard water stains, lime, and rust. Additionally, citric acid is used in wine production to enhance flavour and balance acidity.
While citric acid is predominantly beneficial, it is important to note that it can cause adverse reactions in some individuals when present in packaged foods. These reactions may be linked to GMO ingredients, mould, or allergies. Therefore, it is always advisable to consult a healthcare professional before introducing new substances, especially in concentrated or supplemental forms.

It can be used to adjust pH levels
Citric acid is a weak acid that occurs naturally in citrus fruits, especially lemons and limes. It is odourless, colourless, and has a sour taste. Citric acid is used in fragrance oils to adjust pH levels in several ways.
Firstly, citric acid is a natural pH adjuster and corrector. This means that it can be used to alter the acidity or alkalinity of a solution. The pH of lemon juice, for example, is about 2 or 3, which is acidic. Citric acid can be added to fragrance oils to achieve a similar level of acidity.
Secondly, citric acid is often used as a preservative and stabiliser in fragrance oils. By adjusting the pH, citric acid can help to prevent the growth of bacteria and increase the shelf life of the product. This is particularly useful for fragrance oils that are intended for use in cosmetic or personal care products, as it can help to ensure the product remains stable and effective over time.
Additionally, citric acid can be used to enhance the performance of other active ingredients in fragrance oils. By adjusting the pH, citric acid can influence the behaviour of these ingredients, potentially improving their effectiveness.
Citric acid is also known to have disinfectant properties. By lowering the pH and creating a more acidic environment, citric acid can inhibit the growth of bacteria, viruses, and fungi. This makes it a useful ingredient in fragrance oils intended for cleaning or sanitising purposes.
Overall, the ability to adjust pH levels is a critical function of citric acid in fragrance oils. It not only influences the acidity of the product but also enhances stability, improves the performance of other ingredients, and contributes to disinfectant properties.

Citric acid is a versatile additive with numerous benefits. It is often used to boost acidity, enhance flavours, and preserve ingredients in food and beverages. It is also added to canned fruits and vegetables to prevent botulism, caused by the toxin-producing Clostridium botulinum bacterium.
In medicines, citric acid helps to stabilize and preserve active ingredients, and it can be used to enhance or mask the taste of chewable and syrup-based medications. It also acts as an anticoagulant, preventing blood clots by binding to calcium ions, a key component of the blood-clotting process.
Citric acid is also an effective disinfectant against various bacteria and viruses. It is commercially sold as a general disinfectant and cleaning agent, removing soap scum, hard water stains, lime, and rust.
One specific application of citric acid is in the removal of iron contamination. It is used as a chelating agent to remove iron contamination (Fe) from steel drums or during distillation. This process is particularly useful for lightening fragrance oils such as patchouli oil, clove oil, cinnamon oil, and vetivert oil if they darken after storage in steel drums. To achieve this, about 0.5-1% of citric acid is added to the oil and left for 7-14 days. The citric acid can then be removed by decanting the clear liquid or filtering it through a fine mesh.
