Chitin biomass, a rich renewable resource, is the second most abundant natural polysaccharide after cellulose. Conversion of chitin biomass to high value-added chemicals can play a significant role in alleviating the global energy crisis and environmental pollution. In this review, the recent achievements in converting chitin biomass to high-value chemicals, such as 5-hydroxymethylfurfural (HMF), under different conditions using chitin, chitosan, glucosamine, and -acetylglucosamine as raw materials are summarized. Related research on pretreatment technology of chitin biomass is also discussed. New approaches for transformation of chitin biomass to HMF are also proposed. This review promotes the development of industrial technologies for degradation of chitin biomass and preparation of HMF. It also provides insight into a sustainable future in terms of renewable resources.
甲壳素生物质是一种丰富的可再生资源,是仅次于纤维素的第二大丰富的天然多糖。将甲壳素生物质转化为高附加值化学品,可以在缓解全球能源危机和环境污染方面发挥重要作用。在这篇综述中,总结了在不同条件下,以甲壳素、壳聚糖、氨基葡萄糖和 N-乙酰氨基葡萄糖为原料,将甲壳素生物质转化为高价值化学品,如 5-羟甲基糠醛(HMF)的最新研究进展。还讨论了甲壳素生物质预处理技术的相关研究。还提出了将甲壳素生物质转化为 HMF 的新方法。本综述促进了甲壳素生物质降解和 HMF 制备的工业技术的发展。它还为可再生资源的可持续未来提供了思路。
