Matters needing attention in eating rape flowers:
1, cooked rape flowers are not suitable for overnight, because they contain a certain amount of nitrate, which will turn into nitrite after a certain period of storage, which is very bad for the health.
2. When the rape blossoms are usually fried, they should be fried quickly in a big fire, so as to keep the fresh and crisp taste and the nutrients will not be lost.
3. Never use water above 60℃ when taking rape pollen, otherwise it will seriously destroy the nutrients in rape pollen. If the rape pollen is washed with water with excessive temperature, the efficacy will be greatly reduced.
