摘要: 本文研究微波加热原始水分和充分水化米糠对其游离脂肪酸含量,蛋白质溶解性和乳化活性的影响。结果表明,米糠水分含量对微波稳定化效果影响很大。微波加热原始水分米糠能够部分抑制脂肪水解酶活性,对可溶性蛋白质含量和蛋白质乳化活性影响很小,可用于米糠短期储藏。经微波稳定化处理的充分水化米糠于35℃储藏4周,其游离脂肪酸值几乎未变,但米糠功能性质破坏较大。

Abstract: Effects of microwave heating of rice bran with original moisture content and fully watering rice bran on contents of free fatty acids(FFA), protein solubility and emulsifying activity were studied. Results show that the effect of moisture content on rice bran stabilization is great. Microwave heating of rice bran with original moisture content can partially restrain the activity of lipase and has very little effect on protein solubility and emulsifying activity. It can be used for short period storage of rice bran. The FFA content of fully watering rice bran almost remained unchanged and its functional properties weredestroyed a lot after the rice bran was heated by microwave and then storaged at 35℃ for 4 weeks.
