關於冰凍蔬菜的營養問題。

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，這個我不用讀其他文章。我親自試驗過，-20 C 冷凍一個月內，對冰凍組織變化不大。我曾在實驗室分析生物樣品成分的。-80 C 可以存兩三年呢。
