爆裂玉米是一种专门用来爆制玉米花的玉米品种,是玉米中的一个类型。它和普通的硬粒型、马齿型玉米的主要区别是:爆裂玉米的果穗和籽粒一般都较小。因此籽粒产量较低。其胚乳全部由角质淀粉所组成,在淀粉粒外面有一层坚韧而富弹性的胶质把它包嵌住。在加热的条件下,淀粉粒内产生蒸气压力,当压力逐步增加,直到超过胶质的封闭力时,便发生爆炸,于是整个籽粒亦随之爆炸开来。这就是营养丰富、香脆可口的爆玉米花。而普通玉米则一般无此特性, Burst corn is a corn variety used exclusively for popcorn and is a type of corn. The main difference between it and ordinary hard-type, dent corn is: pop corn and ears are generally small ears. The grain yield is therefore lower. Its endosperm is composed entirely of keratin starch, with a layer of tough and flexible gum outside of the starch granules holding it in place. Under heated conditions, the starch granules produce vapor pressure which explodes as the pressure gradually increases until it exceeds the closing force of the gum, so that the whole kernel explodes. This is a nutritious, crisp and delicious popcorn. Ordinary corn is generally no such characteristics,
