Rice stubble is agricultural waste consisting of cellulose which can be converted to carboxymethyl cellulose from rice stubble (CMCr) as a potential biomaterial. Plasticizer types (glycerol and olive oil) and their contents were investigated to provide flexibility for use as food packaging material. Glycerol content enhanced extensibility, while olive oil content improved the moisture barrier of films. Additionally, CMCr showed potential as a replacement for up to 50% of commercial CMC without any changes in mechanical and permeability properties. A mixture of plasticizers (10% glycerol and 10% olive oil) provided blended film with good water barrier and mechanical properties comparable with 20% individual plasticizer. Principle component (PC) analysis with 2 PCs explained approximately 81% of the total variance, was a useful tool to select a suitable plasticizer ratio for blended film production. Therefore, CMCr can be used to form edible film and coating as a renewable environmentally friendly packaging material.
稻秸是一种农业废弃物，主要成分为纤维素，可将其转化为羧甲基纤维素稻秸（CMCr），作为一种有潜力的生物材料。研究了增塑剂类型（甘油和橄榄油）及其含量，以提供柔韧性，用作食品包装材料。甘油含量提高了可拉伸性，而橄榄油含量提高了薄膜的防潮性能。此外，CMCr 可作为商业 CMC 的替代品，替代量高达 50%，而机械和渗透性能没有任何变化。混合增塑剂（10%甘油和 10%橄榄油）提供了具有良好水阻隔性和机械性能的混合膜，与 20%的单一增塑剂相当。用两个主成分（PC）进行的主成分分析解释了大约 81%的总方差，是选择混合膜生产中合适的增塑剂比例的有用工具。因此，CMCr 可用作可食用薄膜和涂层，作为一种可再生的环保包装材料。
