科學圖說

馬鈴薯俗稱洋芋,是全世界常見的美味塊莖食物。切塊烹調時,常會在手中殘留澱粉顆粒粉末,究竟這些美味的粉末藏在哪裡?使用小刀將洋芋切薄片,以甲基藍稍微染色後,放在顯微鏡下觀察,這些澱粉顆粒就如同盛產的玉石般,規則且美麗地綻放在塊莖的薄壁細胞中。

Introduction

The potato is among the most common tubers in the world. If you cut a potato into pieces and cook it, starch granules appear. Where do these tasty starch granules come from? A small knife was used to cut a potato into thin slices, which were lightly stained with methyl blue and observed under a microscope. These starch granules appear like pieces of jade, arranged neatly and beautifully inside the thin-walled cells of this tuber.
