不同油爆条件对不同类型爆裂玉米爆花特性影响

为研究不同油爆条件对不同类型爆裂玉米爆花特性影响,选取蝶型和球型两类爆裂玉米,分析不同加油量和处理温度对其特性的影响。研究表明,对于膨爆倍数,加油量和处理温度对不同类型爆裂玉米的影响不显著,而膨爆倍数在40%~50%的加油量时为最佳,等体积下的蝶型需油量更多,蝶型的适宜处理温度低于球型。爆花温度受加油量影响明显且呈显著正相关,而处理温度影响不明显,不同加油量和处理温度下,蝶型平均爆花温度高于球型。爆花起始和总时间受加油量影响并呈显著负相关,处理温度影响不显著,但随处理温度增加呈下降趋势。由此可见,油爆时爆花温度和时间主要受加油量影响,而蝶型和球型爆裂玉米适宜处理温度不同。

Effect of Different Oil Popping Conditions for Popping Quality of Diverse Types Popcorn

In order to analysis the effect of different oil popping conditions for popping quality of different types popcorn,the butterfly-type and ball-type popcorn were tested with different quantity and temperature of oil.The analysis showed that the effect of different percentage and temperature of oil was not significant on popping multiples,while the popping multiples was the best in 40 % and 50 % oil percentage. At the same time,the butterfly-type popcorn required more oil than ball-type popcorn with same volume. The optimum oil temperature of butterfly-type was lower than that of ball-type. There had a significant positive interrelationship between the oil quantity and the popcorn popping temperature,but that of oil treatment temperature and the popcorn popping temperature was insignificant. The popping temperature of butterfly-type popcorn overall exceeded that of ball-type popcorn in the different oil popping condition. And then,there was a significant negative correlation between the popping starting time or total time and the oil quantity. Although the interrelationship of the oil treatment temperature with popping starting time or popping total time was not significant,which time were almost down with increasing of treatment temperature. Overall,during oil popping,the oil quantity had a significant effect to popcorn popping temperature and time,meanwhile butterfly-type and balltype popcorn had diverse optimum oil temperatures.
