Why Is Arugula Bitter?

Arugula, also known as rocket, is a leafy green vegetable that has a distinct, slightly bitter flavor. It is a popular ingredient in salads, sandwiches, and other dishes, and is often used as a garnish. But why is arugula so bitter?

The Science Behind Arugula’s Bitter Taste

Arugula’s bitterness is caused by a compound called glucosinolate. Glucosinolate is a sulfur-containing compound that is found in many cruciferous vegetables, such as broccoli, cauliflower, and Brussels sprouts. When these vegetables are chewed, the glucosinolate is broken down into a variety of compounds, including isothiocyanates. Isothiocyanates are responsible for the bitter taste of arugula.

The Benefits of Arugula’s Bitter Taste

The bitter taste of arugula is not just a nuisance; it can actually be beneficial. Studies have shown that glucosinolates and isothiocyanates have anti-cancer properties. They can help to reduce the risk of certain types of cancer, such as colon, prostate, and breast cancer.

In addition to its anti-cancer properties, arugula is also a good source of vitamins and minerals. It is high in vitamin A, vitamin C, and folate, as well as calcium, iron, and potassium. Arugula is also a good source of dietary fiber, which can help to keep you feeling full and satisfied.

How to Reduce the Bitter Taste of Arugula

If you find the bitter taste of arugula to be too strong, there are a few ways to reduce it. One way is to blanch the arugula before using it. Blanching involves briefly boiling the arugula in water, then draining it and running it under cold water. This process helps to reduce the bitterness of the arugula.

Another way to reduce the bitterness of arugula is to pair it with other ingredients. For example, adding a sweet ingredient, such as honey or dried fruit, can help to balance out the bitterness of the arugula. You can also add a creamy ingredient, such as avocado or cheese, to help mellow out the flavor.

Conclusion

Arugula’s bitter taste is caused by a compound called glucosinolate. This compound has anti-cancer properties and is also a good source of vitamins and minerals. If you find the bitter taste of arugula to be too strong, there are a few ways to reduce it, such as blanching or pairing it with other ingredients. No matter how you choose to enjoy it, arugula is a nutritious and delicious addition to any meal.
