What is Taro and Why is it Purple?

Taro is a root vegetable that is widely used in many cuisines around the world. It is also known by other names such as cocoyam, dasheen, and eddoe. The plant is a member of the Araceae family and is native to Southeast Asia and India. The plant is cultivated for its starchy root, which is often used in cooking.

Taro has a brown, hairy exterior and a white, starchy interior. It can be prepared in many different ways, including boiled, fried, mashed, or roasted. Taro is a versatile ingredient and can be used in sweet or savoury dishes, such as soups, stews, curries, desserts, and snacks.

Taro is also a good source of dietary fibre, vitamins, and minerals, and has been used in traditional medicine for its various health benefits. However, it should be noted that raw taro can be toxic if not properly prepared, so it is important to cook it thoroughly before consumption.

Why is Taro Purple?

Not all taro is purple, but some varieties of taro do have a purple colour. The purple colour in taro is due to the presence of anthocyanins, which are natural pigments that are also found in many other purple foods such as blueberries and grapes.

Anthocyanins are water-soluble pigments that are produced by the plant in response to environmental factors such as light, temperature, and soil conditions. They play a role in protecting the plant from UV radiation and other stresses and also attract pollinators and seed dispersers.

In purple taro, the anthocyanins are concentrated in the outer layer of the root, giving it a purple colour. The interior of the root is usually still white or cream-coloured. The purple colour of taro can also vary depending on the pH of the soil it is grown in, with more acidic soils producing a deeper purple colour.

Overall, the purple colour of taro is a result of natural processes within the plant, and it adds both visual interest and potential health benefits to this versatile root vegetable.
