In order to efficiently utilize mushroom-processing waste discharge, insoluble fiber (FVIF) from aged Flammulina velutipes stipe was prepared with a series of wet milling steps of colloid mill (CM), PFI, low pressure homogenization (LPH) and high pressure homogenization (HPH) and formed into film by casting method. The SEM images depicted that morphology and size of FVIF varied (fibrous to spherical; 5 um to 50 nm) with a tendency of uniform and micronization as homogenization intensity increased. Accordingly, HPH-fiber film presented a smoother surface and more compact internal structure, especially a higher tensile strength (49.83 ± 3.63 MPa) and a better barrier property to water vapor (0.095 ± 0.003^a g·mm/m²·h·kPa) and oxygen (9.96 ± 0.63 meq/kg). Moreover, HPH benefited the film's thermal stability, color and transparency. It confirmed that film performance is closely associated with fiber morphology and HPH provides a potential approach to develop new edible film from mushroom byproducts.

在从老化为了有效地利用蘑菇处理废物排放，不溶性纤维（FVIF）金针菇菌柄用一系列胶体磨（CM），PFI，低压均质化（LPH）和高压均质的湿研磨步骤（其制备HPH）并通过流延方法形成薄膜。SEM图像显示FVIF的形态和大小变化（从纤维到球形；从5微米到50纳米），随着均质化强度的增加，具有均匀化和微粉化的趋势。因此，HPH纤维薄膜具有更光滑的表面和更紧凑的内部结构，尤其是更高的拉伸强度（49.83±3.63 MPa）和更好的对水蒸气的阻隔性（0.095±0.003 ^a  g·mm / m ^2）·h·kPa）和氧气（9.96±0.63 meq / kg）。此外，HPH有利于薄膜的热稳定性，颜色和透明性。它证实了薄膜的性能与纤维的形态密切相关，HPH为从蘑菇副产品开发新的可食用薄膜提供了一种潜在的方法。
