About

The black gram (Vigna mungo) is a bean grown in South Asia. Like its relative the mung bean, it has been reclassified from the genus Phaseolus to Vigna. The product sold as black gram is usually the whole bean, whereas the split bean (the interior being white) is called white lentil. It should not be confused with the much smaller true black lentil (Lens culinaris).

Black gram originated in South Asia, where it has been in cultivation from ancient times. It is very widely used in South Asian cuisine. In India the black gram is one of the important pulses grown in both kharif and rabi seasons. This crop is extensively grown in the southern part of India and the northern part of Bangladesh and Nepal. In Nepal it is known as maas and mash daal in Bangladesh. It is a popular daal (legume) side dish in South Asia that goes with curry and rice as a platter.

Uses

It contains high levels of protein (25 g/100 g dry weight), potassium (983 mg/100 g), calcium (138 mg/100 g), iron (7.57 mg/100 g), niacin (1.447 mg/100 g), thiamine (0.273 mg/100 g), and riboflavin (0.254 mg/100 g). Black gram complements the essential amino acids provided in most cereals and plays an important role in the diets of the people of Nepal and India. Black gram is also very high in folate (628 μg/100 g raw, 216 μg/100 g cooked).
