Those Black Specks in Your Cornmeal: Are They Dangerous?

Ever noticed those tiny black specks in your cornmeal? They might seem unsettling, but are they cause for concern? This common occurrence has sparked many questions, and thankfully, science has some answers.

What Are Those Black Specks?

According to a study published in the Journal of Food Science by researchers at the University of Illinois, those specks are usually corn germ, the embryo of the corn kernel [1]. This germ is rich in nutrients and oils, contributing to the cornmeal's flavor and nutritional value.

Why Are They Black?

The black color comes from the pericarp, the outer layer of the germ. This layer contains pigments called anthocyanins, which are also found in blueberries and red grapes. These pigments are responsible for the dark color and are actually beneficial antioxidants.

Are They Harmful?

While the black specks may look alarming, they are not harmful and are perfectly safe to consume. In fact, they add nutritional value to the cornmeal.

How to Avoid Them?

If you find the specks aesthetically displeasing, there are a few things you can do:

• Purchase finely ground cornmeal: Finely ground cornmeal has less of the germ, resulting in fewer black specks.
• Sieve the cornmeal: Using a fine-mesh sieve can remove most of the specks before cooking.
• Cook the cornmeal: The black specks become less noticeable when cooked into a dish.

A Little More About Cornmeal:

• Cornmeal is a staple in many cultures worldwide, adding versatility to dishes from cornbread and tortillas to polenta and porridge.
• It's a good source of fiber, iron, and B vitamins.
• When selecting cornmeal, look for varieties labeled "degerminated" if you want to minimize the presence of black specks.

In Conclusion:

Those black specks in your cornmeal are simply a part of the natural grain. They are harmless and even nutritious, adding to the overall flavor and nutritional value of your meal. So, don't be alarmed by their appearance – enjoy your cornmeal guilt-free!
