| 摘 要： | 对爆裂玉米爆裂特性的研究结果表明：爆裂初始温度为１７０℃，爆花率仅为２．４７％，膨胀系数也只有１．８３。随温度的升高爆花率与膨胀系数急剧上升，到２００℃时爆花率和膨胀系数最高，分别达到９８．７６％和３５．４，高于２００℃二者缓慢降低。不同原料粒度对膨胀系数和单花体积影响较大，而对爆花率影响较小。膨胀系数以５～６ｍｍ最高达２９．２，＞７ｍｍ最低为２１．０３；单花体积以６～７ｍｍ最高达４．４４ｃｍ３，以４～５ｍｍ最低为２．３２ｃｍ２。

| Abstract: | The popping characteristics of popcorn were investigated. The results showed that the initial temperature was 170. But the popping percentage and the expansion efficiency were only 2.47% and 1.83 respectively at this temperature. As the temperature increased, the popping percentage and the expansion efficiency increased dramatically. The highest popping percentage and the expansion efficiency were obtained at 200,being 98.76% and 35.4 respectively. They decreased slowly at higher temperature. Different grain sizes effectively influenced the expansion efficiency and the single flower size with the exception of the popping percentage. The highest expansion efficiency of 29.2 was obtained from grains of 56mm and the lowest one of 21.03 was obtained if the grains were bigger than 7mm. The single flower reached its biggest size of 4.44cm3 from grains of 67mm and the smallest size of 2.32cm3 was obtained from grains of 45mm. |
