中文摘要:

      纤维素是自然界中分布最广、储量最大的天然高分子材料, 具有生物相容性好、可再生和可生物降解等优势。通过光合作用, 植物每年可合成的纤维素有数亿万t。其提取与利用一直以来都是研究的热点。本文主要对纤维素提取方法及纤维素在食品工业中的应用进行了阐述。首先介绍了纤维素的分子结构特点、化学性质等, 总结并对比分析了纤维素常用提取方法, 为纤维素的提取研究提供参考。其次, 纤维素及其衍生物的应用领域分布广泛, 但实际利用率依然偏低。本文详细介绍了纤维素在食品工业中(食品安全检测、食品保鲜材料、添加剂、功能性食品)的应用, 同时讨论了纤维素资源对于未来绿色可持续发展的重要性, 以期为提高纤维素的综合利用水平提供一些思路。

英文摘要:

      Cellulose is the most widely distributed and largest natural polymer material in nature, which has the advantages of good biocompatibility, renewable and biodegradable. Through photosynthesis, plants can synthesize hundreds of millions of tons of cellulose every year. Its extraction and utilization have always been the focus of research. This current review mainly described the cellulose extraction methods and the application of cellulose in food industry. Firstly, the molecular structure and chemical properties of cellulose were introduced. The common extraction methods of cellulose were summarized and compared to provide references for the relative studies. Secondly, the application fields of cellulose and its derivatives were widely distributed, but the actual utilization rate was still low. This article focused on the application of cellulose in food industry (food safety testing, food preservation materials, additives and func tional foods) in detail. The importance of cellulose resources for future green and sustainable development was also discussed. This paper could provide some ideas for improving the comprehensive utilization level of cellulose.
