纳米晶纤维素（NCC）作为一种可再生的绿色生物材料在各种增值应用中的使用引起了人们的极大兴趣。由于纤维素含量高且成本低，从丰富的非木质生物质中采购 NCC 变得很有吸引力。使用无机酸的酸水解作为一种简便、低成本且有效的分离 NCC 的方法已被广泛探索。尽管如此，提取过程的技术方面仍然缺乏。本综述收集了利用非木质生物质中的无机酸水解进行 NCC 提取的现有知识，并提供了从原料和相关预处理到最终水解过程中需要考虑的提取参数的重要概述。为了实现NCC生产的操作上可行，本综述分享了对生物质特性和预处理以及水解参数的考虑和挑战，以优化NCC生产和定制其应用。
The use of nanocrystalline cellulose (NCC) as a renewable and green biomaterial in diverse value-added applications has roused substantial interest. Sourcing NCCs from the abundantly available non-woody biomass becomes attractive due to its high cellulose content and low cost. Acid hydrolysis using mineral acids has been widely explored as a facile, low-cost, and efficient way of isolating NCCs. Still, the technical aspect of the extraction procedure is lacking. This review gathers the available knowledge on the NCC extraction using hydrolysis with mineral acids from non-woody biomass and provides a critical overview of the extraction parameters to be considered from the feedstocks and related pretreatment to the final hydrolysis procedure. To fulfill an operationally feasible production of NCCs, this review shares considerations and challenges on the biomass characteristics and pretreatment as well as hydrolysis parameters for optimizing NCC production and tailoring its application.
