Purple Corn: Description, Flavor, Benefits, And Uses

Purple corn is a type of corn that has been cultivated for thousands of years. It is native to the Andes region in South America and was an important crop for the Inca Empire. The kernels are either deep purple or blue-black with a soft texture, and they are used to make various dishes such as tortillas, tamales, soups, pudding, and more. Purple corn has high levels of antioxidants and potential cancer-fighting properties. This article will discuss its history, uses, nutritional value, health benefits, and ways to incorporate it into your diet.

What is Purple Corn? 

Purple corn is a type of corn that comes from Peru and has been grown for many centuries. It has a rich purple color and is packed with beneficial antioxidants, minerals, and vitamins such as C, B6, A, K1, carotenoids, and polyphenols. These nutrients make it a highly nutritious food that can help support good health.

History and Origin of Purple Corn:

A unique variety of purple corn has been grown for a very long time in the Andean region of South America, spanning from Peru to Bolivia and Argentina. These corns are also found in the cool mountain regions of Mexico. The Incas, who were known to employ this ancient strain in their religious rituals and as a food source, are believed to have cultivated it first. The Incas highly valued purple maize for its distinctive flavor, texture, and hue. It has been a staple of South American cuisine for many years and is still used in many traditional dishes.

The purple color of corn comes from a type of antioxidant pigment called anthocyanin, which is found in many other foods, such as blueberries, grapes, and cherries. Purple corn has several nutritional benefits, including helping to reduce cholesterol, improve circulation, protect against cancer, and lower blood sugar levels.

Growing Conditions of Purple Corn:

Purple corn is a resilient crop that can be grown in various climates, although it thrives best in warm and sunny conditions. It needs at least six hours of direct sunlight per day and prefers temperatures between 71-77°F (22-25°C). The soil should be well-draining, moist, and slightly acidic to ensure optimal growth. Purple corn is a drought-tolerant crop that can survive up to four weeks without water.

Seasonality and Availability of Purple Corn:

Purple corn grows best in the southern and southwestern regions of the U.S. (USDA zones 9-11) with a long, warm growing season. Plant it in early spring and harvest in late summer to early fall. Some areas may allow for a second planting in late summer with a late fall harvest. In zones 6-8, the growing season is shorter and planting occurs after the frost danger has passed. Harvest is in late summer. These areas can still grow purple corn by using techniques like mulching and row covers to extend warmth and selecting suitable varieties with shorter growth periods.

In the cooler regions of zones 3-5, growing purple corn can be difficult due to shorter growing seasons and lower temperatures. Gardeners and farmers in these areas often use greenhouses or start seeds indoors to protect plants from the cold and extend the growing season. However, with careful planning and selection of suitable varieties, it is still possible to grow purple corn in these regions, although the planting and harvesting window is typically narrower, from late spring to early fall.

Health Benefits of Purple Corn:

Peruvian corn is a great source of antioxidants that can protect cells from damage and prevent various diseases. It is also rich in dietary fiber, vitamins, minerals, and phytonutrients. Purple corn, in particular, contains anthocyanins that give it its bright color and offer several health benefits, such as reducing cholesterol levels, improving blood circulation, guarding against cancer, and lowering blood sugar levels. Furthermore, purple corn contains zeaxanthin and lutein, which are powerful antioxidants that can protect the eyes by filtering out blue light that can harm them.

As far as I know, the purple corn has no significant side effects and is safe to eat. But as always, a doctor or a medical professional is the right person to advise you on the health benefits.

Can Dogs Eat Purple Corn?

Yes, dogs can indeed eat cooked purple corn with no added ingredients. However, it is important to be aware of any potential corn allergies your dog may have prior to feeding. I always recommend that you consult your vet before introducing a new type of food or any food that you are unsure about.

Where are Purple Corn Grown and Harvested?

Purple corn is typically grown in the Andean region of Peru, Bolivia, Ecuador, and other parts of South America. The plant is found at higher altitudes, usually between 4500-6500 feet. It’s also grown in some parts of Europe, such as Italy and Austria.

You can sow the purple corn seeds directly into the soil. These corns are an early-maturing corn variety, and you will have the harvest ready within 60 to 62 days after planting.

The harvesting season for purple corn typically falls between July and October, depending on the climate of the region. The cobs are harvested at the point when they turn a deep purple color and become dry. It is important to harvest the corn at the right time to ensure that it retains maximum nutritional value. After harvesting, the kernels can be dried or boiled and used for various traditional foods and beverages.

What is the Flavor Profile of Purple Corn?

Purple corn has a sweet and unique flavor that can best be described as a cross between blueberry, raspberry, and honey. It also carries subtle notes of vanilla and freshly cut grass. Depending on the variety of purple corn used, some may have nuttier or spicier undertones. The sweetness intensifies when cooked or boiled, making it the perfect addition to various dishes. 

Where can the Best Quality Purple Corn be found?

The best quality purple corn can be found at local farmers’ markets, specialty health stores, and online retailers. When purchasing online, make sure to do your research and look for brands that specialize in organic, non-GMO ingredients. Additionally, check the product label for the country of origin—it should be South America, where most of the world’s purple corn is produced. 

How do you store Purple Corn?

To keep purple corn fresh, it should be stored away from sunlight and kept in an airtight container. When stored at room temperature or in the refrigerator, it can last up to three months. If you want to keep it fresh for a longer time, you can freeze it for up to six months. For best results, it is recommended to defrost it gradually in the refrigerator before use.
