【摘要】 甘蔗渣、大豆秸秆、玉米秸秆等农产品废弃物都含有较多的纤维素，纤维素通过机械处理或化学处理等各种方式制备出纳米纤维素，具有可再生、可自然分解、化学性能稳定特点，被广泛应用于食品行业、包装材料、生物医药等领域，加之可以解决农产品副产物高附加值深加工的现实问题，因而受到科研者的持续关注。本文介绍了纳米纤维素的分类、制备方法及在食品工业、生物医药、造纸行业中的应用，分析了当前纳米纤维素制备可能存在的问题，并对纳米纤维素进行了展望，旨在为其综合开发利用提供参考。更多还原

【Abstract】 Bagasse, soybean straw, corn straw and other agricultural product wastes contain more cellulose.Nanocellulose is prepared from cellulose by mechanical treatment or chemical treatment. Nanocellulose has the characteristics of being renewable, naturally decomposable and stable in chemical properties. It is widely used in the food industry, packaging materials, biomedicine and other aspects. In addition, it can solve the practical problems of deep processing of high added-value by-products of agricultural products, received continuous attention from researchers. This paper introduced the classification, preparation methods of nanocellulose and its application in the food industry, biomedicine, and paper industry, analyzed the current possible problems in the preparation of nanocellulose, and gave an outlook on it, hoping to provide a reference for the comprehensive development and utilization of nanocellulose.更多还原
