Brief comments on leek and leek
Leek, also known as leek bud, leek bud, leek and so on. It is the product of softening and yellowing of leek. It grows completely in the dark because it is isolated from light. Without sunlight, chlorophyll can't be synthesized by photosynthesis, and it will turn yellow, which is called "leek yellow".
Leek yellow is yellow and white because it doesn't see the sun, and its nutritional value is not as good as leek. Leek yellow tastes fragrant because it sells well, and its value far exceeds that of green leek. In fact, in terms of nutritional value, leek and green leek are not the same. For example, compared with leek, the carotene of green leek is 4.4 times higher. Vitamin C is 0.6 times higher, and selenium (an important element of antioxidant defense system) is 0.45 times higher.
