根據伊利諾斯大學的研究，用華氏140度加熱10分鐘最好

"As scientists, we learned that sulforaphane is maximized when broccoli has been heated 10 minutes at 140 degrees Fahrenheit," said Jeffery. "For the consumer, who cannot readily hold the temperature as low as 140 degrees, that means the best way to prepare broccoli is to steam it lightly about 3 or 4 minutes--until the broccoli is tough-tender."

如果你沒有辦法用140度這麽低的溫度，那稍差的辦法就是蒸3-4分鐘。
