So, what is citric acid? Citric acid is an acidity regulator; it is an organic acid commonly found in fruits such as lemons and limes but is also produced synthetically for use in the food and beverage industry. It is a critical ingredient in many of our favorite foods and beverages, contributing to their flavor, preservation, and texture. With its sour taste and ability to control acidity levels, citric acid plays a crucial role in the food industry. Let's dive into the sources and properties of citric acid together.
1. Citric acid natural source
You've tasted citric acid if you've ever bitten into a lemon. Citric acid is a weak acid that occurs naturally in all citrus fruits. It is commonly associated with citrus fruits such as lemons, limes, and oranges due to their high levels of citric acid. However, it can also be found in smaller quantities in other fruits like berries, pineapples, and kiwis and vegetables like tomatoes and broccoli.
Natural citric acid is commonly used in specialty and organic food products, emphasizing pure, natural ingredients. While synthetic citric acid is often cheaper and more consistent in production, some food and beverage companies prefer to use natural citric acid. This is because it is considered a healthier and more natural alternative to synthetic citric acid.
In conclusion, citric acid is a vital ingredient in the food and beverage industry, with natural sources such as citrus fruits and vegetables being abundant and essential sources. Despite its extraction and consistency limitations, natural citric acid is highly valued for its pure and natural qualities.
2. Synthetic production
While natural sources of citric acid are abundant and vital, synthetic production of citric acid is the most common method of obtaining this versatile ingredient. Over 70% of the citric acid used in the food and beverage industry is produced through synthetic means. The process involves the fermentation of sugars such as corn, molasses, or sugar beets using specific strains of Aspergillus niger, a type of fungus that produces citric acid as a byproduct of its metabolism.
The synthetic production of citric acid has several advantages over natural sources. It is less expensive and more consistent in quality, making it the preferred choice for large-scale food and beverage manufacturers. Synthetic citric acid is also free from impurities that may be present in natural sources, such as pesticides or heavy metals.
However, some may prefer natural citric acid for perceived health benefits and taste. Natural citric acid is often used in specialty and organic food products, emphasizing pure, natural ingredients. Whether natural or synthetic, citric acid remains essential in many of our favorite foods and beverages.

Although citric acid has been given the FDA's approval as being generally harmless, it has been linked to adverse responses in persons sensitive to citrus. Occasionally, it can also trigger nausea and vomiting due to an upset stomach. Nonetheless, citric acid is regarded as safe for intake. It has been demonstrated to have various health benefits, such as assisting digestion and limiting the growth of dangerous germs in food when taken moderately. Use caution when adding citric acid to your diet, as with any other food additive, and stick to the recommended serving size.
The FDA regulates the use of citric acid in food under the Code of Federal Regulations (CFR), which sets standards for the identity, quality, and purity of food ingredients. According to the CFR, citric acid is generally recognized as safe (GRAS) for use in food at levels consistent with good manufacturing practices (GMP). The FDA also monitors the use of citric acid in food through its food additive petition process, which requires manufacturers to provide data demonstrating the additive's safety before it can be approved for use in food.
In the European Union (EU), citric acid is also considered safe for use in food and is listed as an authorized food additive in the EU's list of approved additives. The EU also limits the amount of citric acid used in food and drinks. Generally, citric acid is used in concentrations of 0.1% to 0.5% in foods and beverages. However, the specific dosage standards may vary based on regulatory requirements in different countries and regions.
In the cosmetic industry, the EU and the FDA regulate citric acid as a cosmetic ingredient. Companies must follow strict labeling and safety requirements, including disclosing all ingredients used in the product.
Citric acid, as a souring agent, has the characteristic of a smooth and delightful sour taste. It is widely used in carbonated drinks, juice, canned fruits, etc. Citric acid can be perceived at the lowest concentration of 0.0025%-0.08%. The usual dosage is 0.1%-0.5%, which depends on the variety and specific needs. In certain fruit and vegetable products, the sugar-acid ratio of the product can be adjusted by using citric acid and sugar, thus improving the flavor of the product.
Fruit and vegetable materials soaked in a mixture of 1%-2% salt and 0.1% citric acid can inhibit discoloration caused by enzymatic browning in the raw materials.
In canned fruits, jams, jellies, and other products, citric acid can lower the pH value and inhibit the growth of spoilage microorganisms. Most spoilage bacteria can be suppressed when the pH value is less than 5.5. Adjusting the pH value with citric acid can also improve the quality and flavor of the product.
Juices, jellies, and other condiments frequently use citric acid as an ingredient. It's not just a flavor enhancer but a preservative as well. However, there could be complications if it is not used correctly or if you have an allergy to it.
1.Allergic Reactions
Citric acid can cause skin irritation, rashes, and itching in sensitive individuals. Citric acid can rarely trigger severe reactions like anaphylaxis.
2. Impact on Tooth Enamel
Studies have shown that people who drink many acidic beverages, such as sodas, may be at increased risk for cavities and tooth decay because of the citric acid in these drinks.
3. Dangers of Overconsumption
There are worries regarding the hazards of overconsumption, even though citric acid is typically deemed safe in small amounts. Research has linked citric acid to digestive issues such as acid reflux and disrupting the body's natural mineral balance.
Citric acid is widely utilized in the food and beverage sector and is generally deemed safe in moderation; thus, while these issues and controversies should be taken seriously, it is essential to note that it is used in such large quantities. Consuming citric acid in moderation and combination with other components can help to balance its effects and reduce the severity of many of these concerns.
We've delved into citric acid and explored its origins, uses, safety precautions, and more. From its natural sources in citrus fruits and vegetables to its synthetic laboratory production, citric acid is a versatile and vital ingredient in the food and beverage industry.
