摘要

For realizing the high-valued utilization of agricultural by-products and investigating the feasibility of their functional production, we focused on developing biodegradable/edible films based on insoluble dietary fibers (IDF) derived from dried Lentinus edodes (L. edodes) stems and aged Flammulina velutipes (F. velutipes) with a two-stage treatment containing physical processing (colloidal milling and PFI grinding) and chemical treatment (hydrogen peroxide bleaching). Undergoing the bleaching treatment, the IDFs with a reduced size and regular shape effectively improved the performances of edible films. Scanning electron micrographs showed that the bleached L. edodes (BLF) film displayed a smoother surface and more compact internal structure compared to the others. Furthermore, BLF film possessed the highest tensile strength (24.37 +/- 0.88 MPa) and an effective barrier to water vapor (0.253 +/- 0.016 g mm/m(2).h.kpa) and oxygen (10.03 +/- 0.97 meq/kg). This study demonstrated that the insoluble fiber dissociated from edible mushroom byproducts has good potential for producing the edible films.
