Tartaric acid and citric acid are both important members of the food additive family. As a premium supplier of both tartaric acid and citric acid, Polifar will focus on their applications in the food industry and explain their main differences.
Food-grade tartaric acid has a more intense flavor—tart, astringent, spicy, sharp, and intense—with a strong acidity boost, 1.2 to 1.3 times that of citric acid. It's one of the most suitable acidity regulators for products like energizing, sour candies or fruit wines.
Citric acid has a fresher, cleaner, smoother, more natural, and purer flavor. In food, it perfectly complements other tastes, and is indispensable in everyday beverages like soft drinks and yogurt.
Pure natural tartaric acid is widely found in various berries, especially grapes and mulberries. Typically, tartaric acid is produced during the fermentation process of winemaking, forming crystals in the barrels. As a distributor of tartaric acid, Polifar typically sources high-quality natural tartaric acid to ensure the highest purity and quality delivered to our customers. You can find food-grade tartaric acid powder in our product catalog.
Citric acid is widely found in various citrus fruits and Rutaceae plants, especially lemons, oranges, and limes. With the maturity of modern industrial technology, citric acid is mainly obtained through large-scale microbial fermentation. It boasts abundant raw materials, mature processes, and extremely high yields, making it the world's most widely used food acidity regulator.
Generally, acids can inhibit bacterial growth, thus achieving a preservative effect, such as acetic acid, lactic acid, propionic acid, and sorbic acid. However, in many published studies, tartaric acid's antibacterial properties are weaker compared to other acids. Tartaric acid can inactivate a small number of microorganisms, and its ability to inhibit or weaken bacteria is insufficient. Therefore, its use as a preservative is limited, unless it is used in combination with other preservatives for freshness preservation. Citric acid is commonly used as an acidity regulator, generally inhibiting bacteria by lowering the pH of food, preventing microbial growth. It is often used in conjunction with antioxidants such as Vitamin C for preservation, anti-corrosion, and antioxidant effects.
Tartaric acid has low yield and high cost. It is mainly used in high-end niche applications where citric acid cannot replace it.
During the production of wine and fruit wine, the ripeness of each batch of grapes varies, causing fluctuations in the acidity of the wine. Adding food-grade tartaric acid at this time can precisely regulate the acidity, balance sweetness, and reduce the bitterness of tannins, thereby improving the overall taste of wine and fruit wine.
At the same time, tartaric acid has a unique function of stabilizing wine pigments, effectively preventing discoloration and turbidity, making the wine clearer and cleaner. It is the most important core ingredient in winemaking, which citric acid cannot replace.
When used as an acidity regulator, citric acid is mainly applied to beverages. This is the largest application scenario for citric acid. Carbonated beverages, fruit juices, tea drinks, and lactic acid bacteria drinks can regulate and balance acidity, neutralize sweetness, and enhance the taste, providing a refreshing and mild flavor without masking the beverage's original flavor.
Tartaric acid and citric acid can both be used in baked goods.
Ferment tartar, also known as potassium bitartrate, is a derivative of tartaric acid. In the wide variety of baked goods, tartaric acid is mainly used in the production of whipped egg whites, chiffon cakes, macarons, and meringues. Food-grade potassium bitartrate can reduce the fishy smell of eggs, neutralize the alkalinity of egg whites, stabilize egg white foam, and improve whipping efficiency. The final baked product has better fluffiness, a more delicate texture, does not collapse, and looks better. The function of stabilizing egg white foam is unique to tartaric acid.
Citral acid in baked goods mainly regulates the pH of the dough, improving the texture of the bread. It also enhances the milky and fruity aromas in bread, enriching its flavor profile. It can also be combined with baking soda to make bread fluffier and softer.
Tartaric acid is mainly used in high-end specialty candies, especially hard candies, chewing gum, and bubble candies. Adding tartaric acid creates a unique, sharp, and tangy flavor, distinct from ordinary sour candies. It has a distinctive flavor profile and can even have a strong stimulating effect.
Citral acid, when added to candy, also acts as an acidity regulator, optimizing the sweet-sour ratio and creating a unique taste profile.
Tartaric acid mainly relies on natural extraction, resulting in limited production and a relatively high price. It is more suitable for small-batch, high-end specialty foods with high added value. Large-scale use requires careful consideration of production costs.
Tartaric acid crystallizes easily at low temperatures and is unstable at high temperatures, requiring strict control of the processing environment, especially the production temperature and the appropriate addition ratio.
Citral acid has a mature process, low raw material costs, and can be mass-produced, making it one of the most cost-effective acidity regulators. It is highly suitable for industrial-scale mass production.
Citric acid is heat-resistant and storage-resistant, maintaining its stable function even under high-temperature processing. It does not crystallize, allowing for continuous production lines with minimal environmental requirements.
Both tartaric acid and citric acid are highly safe additives. When added within permitted limits, they pose no health risks. However, this does not mean they can be added to any food product.
Tartaric acid has limited applications, generally used in alcoholic beverages, baking, and confectionery—specifically, high-end product categories. Its use is prohibited or restricted in most infant foods and staple foods, requiring adherence to national regulations.
Citric acid has a wide range of applications, used in most food categories. While there are no strict limits, it should still be consumed within the recommended daily intake range.
What is the role of tartaric acid in baking powder?
Tartaric acid primarily reacts with sodium bicarbonate (baking soda) to produce carbon dioxide gas, balancing the pH of bread and improving cake quality. The carbon dioxide gas forms numerous tiny pores, preventing the pastry from developing a bitter taste or turning yellow after baking and mixing with baking soda, resulting in a fluffier, softer, and more palatable product.
How much tartaric acid should be added to wine?
This depends on the acidity and sugar content of the original grape juice. The amount added should be based on the experience of the winemaker; currently, the market goal is to adjust the wine's pH to between 3.0 and 3.4.
Does tartaric acid expire and become ineffective?
If tartaric acid is stored in a cool, dry, airtight container and is of high purity, it can essentially be stored indefinitely without losing its acidic properties. However, if it becomes damp, clumps, turns yellow, or has an off-odor, do not use it. For pharmaceutical-grade tartaric acid, there is an optimal shelf life, typically 2 to 3 years.
Is tartaric acid harmful to you?
Food-grade tartaric acid is safe and harmless when used in appropriate amounts within the recommended daily intake range. Excessive use can irritate the gastrointestinal tract, worsen stomach conditions, and increase the burden on the kidneys. Exposure to high-purity industrial-grade tartaric acid may cause strong irritation and corrosiveness to the eyes, skin, and upper respiratory tract. However, strict safety protocols must be followed during factory processing and production. If it's pharmaceutical-grade tartaric acid, this is only for improving the overall stability and solubility of the drug; there's no need to worry about health issues.
