Ash is one of the six nutrients in food, and all kinds of inorganic salts needed by human body come from ash of food. Therefore, the content of ash can reflect the nutritional value of food from one aspect. The composition and content of ash in different foods are very different, so ash is an indicator of the total amount of inorganic components in food. The ash content in black beans is 4.47%, which is obviously higher than other beans. Further analysis of the ash composition of black beans showed that zinc, copper, magnesium, molybdenum, selenium, phosphorus and other minerals and trace elements were relatively high.
