In recent years, nanocellulose (NC) has gained significant attention due to its remarkable properties, such as adjustable surface chemistry, extraordinary biological properties, low toxicity and low density. This review summarizes the preparation of NC derived from lignocellulosic biomass (LCB), including cellulose nanofibrils (CNF), cellulose nanocrystals (CNC), and lignin-containing cellulose nanofibrils (LCNF). It focuses on examining the impact of non-cellulosic components such as lignin and hemicellulose on the functionality of NC. Additionally, various surface modification strategies of NC were discussed, including esterification, etherification and silylation. The review also emphasizes the progress of NC application in areas such as Pickering emulsions, food packaging materials, food additives, and hydrogels. Finally, the prospects for producing NC from LCB and its application in food-related fields are examined. This work aims to demonstrate the effective benefits of preparing NC from lignocellulosic biomass and its potential application in the food industry.
近年来，由于纳米纤维素（NC）具有可调节的表面化学性质、非凡的生物特性、低毒性和低密度等显著特性，引起了人们的极大关注。本综述总结了源自木质纤维素生物质（LCB）的 NC 的制备方法，包括纤维素纳米纤维（CNF）、纤维素纳米晶体（CNC）和含木质素的纤维素纳米纤维（LCNF）。本文重点研究了非纤维素成分（如木质素和半纤维素）对 NC 功能的影响。此外，还讨论了 NC 的各种表面改性策略，包括酯化、醚化和硅烷化。该综述还强调了 NC 在 Pickering 乳液、食品包装材料、食品添加剂和水凝胶等领域的应用进展。最后，探讨了从木质纤维素制备 NC 及其在食品相关领域应用的前景。这项工作旨在展示从木质纤维素制备 NC 的有效效益及其在食品工业中的潜在应用。
