Black beans and the science behind them

Michigan is the nation’s second largest producer of all dry beans, and first in the production of black beans.

As the weather chills and we settle into frosty mornings, I often think about hot pots of chili, simmering stews and family time. Whether it’s movie night, game night or cheering the Spartans on to victory, family time at my house includes Mexican, Cuban, Haitian or other spicy food. I enjoy spicy food year round, but I particularly like it when the weather has turned cooler.

Thinking of Mexican or Caribbean cuisine makes me think black beans. Beans are a staple in diets around the world and offer protein in high amounts to people who generally do not eat animal protein in sufficient quantities. I also like pinto, kidney and black eyes peas, but black beans are hands down my favorite go-to bean.

Black beans are medium to small, oval-shaped beans with a shiny black coat. They have a small, white eye or spot called a “keel.” Black beans have a creamy white interior and meaty flavor.

Michigan is the nation’s second largest producer of all dry beans, and first in the production of black beans. Mexico is Michigan’s largest export market for black beans.

Phaseolus vulgaris is the genus and species for beans. The beans we eat—green, navy, kidney, black etc.—are classes of beans. Black beans have become the fastest growing market class of beans, which means people are eating a lot of black beans.

There are also some very interesting products on the market made from black beans, including hummus (traditionally from chick peas), chips (traditionally corn) and even pasta (traditionally wheat).
