Coriander, a herb commonly used in various cuisines, particularly in Middle Eastern, Indian, and Asian cooking, has been a topic of discussion among food enthusiasts and scientists alike. While some people enjoy the unique flavor and aroma of coriander, others find it unbearably bitter. But have you ever wondered why coriander is so bitter? In this article, we will delve into the world of coriander, exploring its history, chemistry, and the reasons behind its bitter taste.
A Brief History of Coriander
Coriander, also known as cilantro, has been used for centuries in various cultures. The herb is native to the Middle East and the Indian subcontinent, where it was used not only as a spice but also for its medicinal properties. The ancient Egyptians, Greeks, and Romans used coriander for its flavor and aroma, as well as for its perceived health benefits.
Coriander was introduced to Europe by the Romans and became a popular spice during the Middle Ages. It was used to flavor food, particularly meat and vegetable dishes, and was also used in the production of beer and wine. Today, coriander is used in many different cuisines, including Mexican, Chinese, and Indian cooking.
The Chemistry of Coriander
So, why is coriander so bitter? The answer lies in its chemistry. Coriander contains a number of compounds that contribute to its bitter taste. The main culprits are:
Aldehydes
Aldehydes are a type of organic compound that are responsible for the bitter taste of coriander. The most common aldehyde found in coriander is (E)-2-decenal, which is also found in other herbs and spices, such as parsley and dill. Aldehydes are highly volatile, which means that they evaporate quickly, releasing their bitter flavor and aroma.
Terpenes
Terpenes are another type of compound found in coriander that contribute to its bitter taste. The most common terpene found in coriander is linalool, which is also found in other herbs and spices, such as lavender and rosemary. Terpenes are responsible for the aroma of coriander and are also known to have antimicrobial properties.
Flavonoids
Flavonoids are a type of compound found in coriander that are responsible for its bitter taste. The most common flavonoid found in coriander is quercetin, which is also found in other herbs and spices, such as onions and garlic. Flavonoids are known to have antioxidant properties and are also responsible for the color of coriander.
Genetic Variation and Coriander Taste
Research has shown that the perception of coriander’s bitter taste is influenced by genetic variation. Some people have a genetic variation that makes them more sensitive to the bitter taste of coriander, while others are less sensitive.
A study published in the journal Flavour found that people who had a certain variation of the OR6A2 gene were more likely to find coriander bitter. The OR6A2 gene is responsible for coding a receptor that detects aldehydes, which are the compounds responsible for the bitter taste of coriander.
Cultural and Environmental Factors
Cultural and environmental factors can also influence the perception of coriander’s bitter taste. For example, people who are exposed to coriander from a young age may become desensitized to its bitter taste, while people who are not exposed to coriander until later in life may find it more bitter.
Environmental factors, such as the climate and soil in which coriander is grown, can also affect its flavor and aroma. Coriander grown in hot and dry climates may have a more intense flavor and aroma than coriander grown in cooler and more humid climates.
Health Benefits of Coriander
Despite its bitter taste, coriander has a number of health benefits. It is a rich source of antioxidants, which can help to protect against cell damage and reduce the risk of chronic diseases such as heart disease and cancer.
Coriander is also known to have anti-inflammatory properties, which can help to reduce the risk of chronic diseases such as arthritis and diabetes. It is also a good source of fiber, which can help to promote digestive health.
Conclusion
In conclusion, the bitter taste of coriander is due to a combination of its chemistry, genetic variation, and cultural and environmental factors. While some people may find coriander unbearably bitter, others enjoy its unique flavor and aroma.
Whether you like coriander or not, it is undeniable that it has a number of health benefits and is a versatile herb that can be used in a variety of dishes. So, next time you are cooking with coriander, remember the complex chemistry and genetics that are behind its bitter taste.

What is coriander and where does it come from?
Coriander is an herb that comes from the Coriandrum sativum plant, which is native to the Middle East, the Indian subcontinent, and Africa. The plant produces small, ball-shaped seeds that are commonly used as a spice, while its leaves are used as an herb in various cuisines.
Coriander has been used for centuries in traditional medicine, cooking, and as a form of currency in some cultures. The seeds and leaves of the plant have distinct flavors and aromas, with the seeds having a warm, earthy, and slightly citrusy taste, while the leaves have a fresh, citrusy, and slightly bitter taste.
Why do some people dislike the taste of coriander?
Research suggests that some people may be genetically predisposed to dislike the taste of coriander due to a variation in the OR6A2 gene, which codes for an olfactory receptor that detects certain aldehyde chemicals found in coriander. This genetic variation can affect the way people perceive the smell and taste of coriander, making it unpleasant for some individuals.
Additionally, cultural and environmental factors can also influence a person’s perception of coriander’s taste. For example, people who are exposed to coriander from a young age may become accustomed to its flavor and aroma, while those who are not exposed to it until later in life may find it unpalatable.
What are the health benefits of coriander?
Coriander has been traditionally used to aid digestion, reduce inflammation, and lower cholesterol levels. The seeds and leaves of the plant contain antioxidants, vitamins, and minerals that can help protect against chronic diseases such as heart disease, diabetes, and certain types of cancer.
Coriander also has antimicrobial properties, which can help prevent the growth of bacteria and other microorganisms that can cause illness. Additionally, coriander has been shown to have anti-inflammatory properties, which can help reduce pain and inflammation in the body.
