Microwave pretreated enzymatic retting of flax stems and comparison with the effect of radio frequency pretreatment

摘要: Abstract Microwave (MW) together with prior water presoaking was used as a pretreatment for enzymatic retting of flax stems in this work. Weight loss, pectin removal, the resulting fibers’ properties and degree absorption after MW were measured analyzed. The effect on determined compared radio frequency (RF) which adopted same processing parameters. It found that 8 h-30 min improved efficiency most, increasing weight loss by 39 %, decreasing content 10.96 % to control obtaining sorption 2.23, produced fibers reasonable tensile performance. Compared RF pretreatment, enabled absorb more energy then got improvement efficiency. And 30 min-MW treatment could improve removal non-presoaked retting, different from treatment. enzyme-retted pretreatments had close properties, however, their values MW-pretreated tended be slightly lower. also performance pretreated, linked amount absorbed, temperature-maintaining time proportion during or treatment, whether been presoaked not.
