中文摘要:

研究了瞬时高温流化对玉米游离酚含量、抗氧化活性的影响，优化出制备高抗氧化活性玉米的最佳工艺条件。结果表明影响玉米抗氧化活性的因素主次次序为：流化温度>流化处理时间>进料速度；最佳工艺条件为：流化温度160 ℃，流化处理时间60 s，进料速度21 kg/h，所制备的玉米游离酚含量为345.88 mg GAE/hg，较原料玉米增加了27%（P

英文摘要:

This research studies the effect of instant high-temperature fluidization on the content of free phenolic and antioxidant activity of corn，and optimizes the conditions of that process. The results show that the fluidizing temperature has the most important effect on antioxidant activity of corn，followed by the fluidizing time and feeding rate，correspondingly，their optimum conditions are 160 ℃，60 s and 21 kg/h，respectively. The content of free phenolic in corn produced as the optimum conditions is 345.88 mg GAE/hg which increases by 27% compared with that of raw corn（P
