Methyl anthranilate (MA) is a fascinating organic compound that plays a significant dual role in the food world. It exists naturally in a variety of fruits and plants, where it contributes to their characteristic aroma and flavor. However, it is perhaps more widely known for its use as a synthetic additive that gives many processed foods and beverages their distinctive and familiar grape-like taste. This article explores both the natural and manufactured sources of this aromatic chemical, shedding light on the different ways it enters our diet.
Natural Food Sources of Methyl Anthranilate
While the grape flavor we often associate with candy is artificial, the real Concord grape is where the story of methyl anthranilate begins. In nature, MA is part of a complex matrix of flavor compounds that define the taste of many foods, though its presence is often in much smaller concentrations than in synthetic products.
Grapes and Grape Products
The most famous natural source of methyl anthranilate is the Concord grape, a species known as Vitis labrusca. This specific compound is largely responsible for the strong, 'foxy' flavor profile that distinguishes Concord grapes from other varieties like European wine grapes. Consequently, MA is a natural constituent of Concord grape juice, grape musts, and certain wines.
Other Fruits and Berries
Methyl anthranilate is not exclusive to grapes. It is also found in other fruits, contributing subtle aromatic notes. These include:
- Strawberries: The woodland strawberry (Fragaria vesca) contains MA, which contributes to its overall sweet, fruity, and grape-like aroma.
- Apples: MA is listed as a primary component of the essential apple flavor, working alongside other esters to create its complex scent.
Citrus and Other Plant-Based Sources
The presence of MA extends to the oils of several citrus fruits and other plants, which are often used in flavoring:
- Mandarin Orange: The essential oil contains MA.
- Lemon and Lime: MA is found in the oils of these fruits.
- Other Plants: Floral sources like jasmine, orange blossom (neroli), and ylang-ylang contain essential oils with MA, which is then used in both perfumery and flavorings.
- Cocoa and Tea: These are also noted as containing methyl anthranilate naturally.
Processed Foods and Artificial Flavors
The vast majority of methyl anthranilate consumed today comes from its use as a synthetic flavor additive. The distinctive, uniform flavor of many 'grape' products is a direct result of adding synthetically produced MA, which can replicate the specific profile of Concord grapes. This synthetic version is a cost-effective way to achieve a consistent taste that consumers recognize and enjoy.
Here are some common examples of processed foods and drinks that contain added methyl anthranilate:
- Soft drinks: Grape soda is a prime example, relying on MA for its characteristic flavor.
- Candy: Many grape-flavored candies, jellybeans, and chews use MA.
- Chewing gum: The classic grape bubblegum flavor is typically derived from synthetic MA.
- Gelatin and Jellies: This flavoring is used to create grape-flavored gelatin mixes and fillings.
- Ice Cream: Some grape-flavored ice creams and sorbets incorporate this additive.
Comparison: Natural vs. Synthetic Methyl Anthranilate
To illustrate the difference in sources and applications, the following table provides a clear comparison.
| Feature | Natural Methyl Anthranilate | Synthetic Methyl Anthranilate |
|---|---|---|
| Source | Plants, especially Concord grapes, strawberries, and citrus oils. | Commercially produced through chemical synthesis or microbial fermentation. |
| Flavor Profile | Part of a complex bouquet of compounds, contributes a subtle grape or fruity note. | Isolated, powerful, and uniform grape-like aroma and flavor. |
| Concentration | Found in very low amounts within natural foods. | Can be added in higher concentrations to achieve a desired flavor intensity. |
| Example Foods | Concord grapes, grape juice, strawberries, and citrus fruit oils. | Grape soda, candies, chewing gum, and flavored beverages. |
Safety and Nutritional Considerations
For those concerned about what is in their food, the good news is that methyl anthranilate has been thoroughly studied and is considered safe for human consumption. The U.S. Food and Drug Administration (FDA) has given it the classification of “Generally Recognized as Safe” (GRAS), and it has been used for decades as a flavoring compound without issue. When naturally occurring in foods like grapes or tea, the amounts are very small, and it's quickly metabolized by the body.
While some consumers may prefer flavors derived exclusively from natural ingredients, the synthetic version offers an accessible and affordable way to enjoy consistent grape and berry flavors in a variety of products. The methods of production for synthetic MA have also been evolving, with microbial fermentation offering a more sustainable, bio-based alternative to older petroleum-based processes.

Conclusion
Methyl anthranilate is the compound behind the iconic grape flavor, whether it’s naturally present in Concord grapes and other fruits or added synthetically to processed foods like candy and soda. Its dual existence highlights the fascinating intersection of natural food chemistry and modern food science. While our bodies metabolize this compound whether it's from a fresh grape or a flavored beverage, the intensity and source of the flavor differ significantly. Understanding what foods have methyl anthranilate in them allows for a more informed appreciation of the flavors we encounter every day.
