How does broccoli suffer?

Broccoli is a cruciferous vegetable. It contains a special substance called glucosinolates, which can reduce the risk of cancer. Because these disease resistant compounds contain sulfur compounds, cruciferous vegetables have a pungent taste, which some people may think has a strange bitter taste.

Broccoli will not be bitter after blanching before frying, and it can keep the color of vegetables, and get rid of peculiar smell, astringency and oxalic acid. However, from the perspective of nutrition, blanching can increase the loss of water-soluble nutrients. Blanching cabbage in 100 ℃ water for two minutes, the loss rate of vitamin C is as high as 65%; After scalding for more than 10 minutes, vitamin C is almost lost. Therefore, appropriate methods should be used to reduce the loss of nutrients. Generally, broccoli is treated by boiling water with more water and blanching for a short time, which can reduce the heat loss of nutrients. Because of the existence of oxidase in vegetable tissue, it can accelerate the oxidation of vitamin C, especially in the water temperature of 60 ℃ - 80 ℃, the activity is the highest. In boiling water, the oxidase is unstable to heat and loses its activity quickly. At the same time, there is almost no oxygen in boiling water, which reduces the loss of vitamin C caused by thermal oxidation.

For our female friends, eating broccoli for a long time can help us reduce the risk of breast cancer. Eating more broccoli has many, many benefits for our body, and it can enhance our children's immunity. It can also improve our memory and help our baby grow healthily.
