香菇膳食纤维挤压改性的研究

Study on extrusion modification of lentinus edodes dietary fiber

采用挤压改性方法处理两种不同工艺制备的香菇膳食纤维 ,在不同的挤压处理条件下 ,香菇膳食纤维的总膳食纤维的量均未改变 ,水溶性膳食纤维的含量分别提高 6%～ 1 5%和 2 %～ 8% ,被改性的物质主要是不溶性纤维中的半纤维素。

Lentinus edodes dietary fiber produced by two different processes is treated by extrusion modification. In the two different conditions the total amount of dietary fiber has no change whereas the content of water soluble dietary fiber increases by 6%～15% and 2%～8% respectively. The modified insoluble fiber is mainly semi cellulose.
