摘要


本文是應用偏振光的原理以電子顯微鏡觀察檢驗馬鈴薯的澱粉粒,利用絞碎的馬鈴薯澱粉顆粒在不同加熱溫度下,尋找其糊化溫度,並使用不同倍率觀察其差異,實驗結果顯示其開始糊化的溫度大約是在60℃左右,並於70℃開始有明顯的糊化作用,本實驗可作為檢驗澱粉或雙折射特性的一種方法。

This article of examines the starch-grains of the potato using the polarized light principle by electron microscopy. We mince the potato to obtain the starch-grains of potato under the different temperature, and to define the gelatinization temperature. The experiment show that the gelatinization temperature is starting in about 60℃, and the obvious gelatinization when the gelatinization temperature in 70℃. This is a kind of method to examine that starch grains or double refraction.
