Because vegetables are usually frozen immediately after harvesting, they generally retain many of their nutrients.

In fact, one study showed that blanching and freezing vegetables for up to 2 months did not significantly alter their phytochemical content.

Frozen vegetables generally retain many of their nutrients. However, freezing may also increase or decrease the nutritional value of certain vegetables.

啊，这个我不用读其他文章。我亲自试验过，-20 C 冷冻一个月内，对冰冻组织变化不大。我曾在实验室分析生物样品成分的。-80 C 可以存两三年呢。
