Good quality lentils are large, with pod length of about 10 cm, fresh skin color, no insects and no injuries. When lentils are stored at low temperature of 0℃ ~ 5℃, they can keep a good appearance. When they are taken out for cooking in a week or so, they will have the smell of uncooked beans, and this smell will become thicker with the increase of storage days, which will affect the cooking flavor. Therefore, the storage period of lentils is not long, and they should be eaten as soon as possible after purchase.

Lentils are an edible material with high nutrient content. There are many kinds of lentils. Different kinds of lentils have different shapes, tastes and cooking methods, so we need to carefully identify them when buying.
