摘要: 本文就瞬时高压作用(InstantaneousHighProcess)对采用酶-化学法制得的麦麸膳食纤维(oatbrandietaryfiber)的改性作用进行了研究。研究结果表明:经过IHP处理后,麦麸膳食纤维的持水力、膨胀率、结合水力都有不同程度的提高;悬浮溶液的表观粘度增大;可溶性膳食纤维(SDF)含量增加;麦麸膳食纤维的形貌特征发生了很大的变化。

Abstract:  Instantaneous high pressure (IHP) was used to modify the physical properties of oat bran dietary fiber which was produced by enzyme-chemistry method. The results showed the IHP treatment raised the water retention capacity, swelling capacity and water-combining capacity of oat bran dietary fiber products; the apparent viscosity of suspension and the content of SDF increased with the overall form of oat bran dietary fiber going through great changes.

Key words: instantaneous high pressure, oat bran dietary fiber, modification
