甘薯渣高值化发酵转化利用研究进展

我国甘薯种植面积和产量均居世界首位。甘薯主要用于生产淀粉及其制品，在此过程中产生的薯渣大部分被直接丢弃，资源浪费和环境污染严重。甘薯渣富含淀粉、膳食纤维、蛋白质等物质，通过微生物发酵可将其转化为膳食纤维、乙醇、单细胞蛋白等高附加值产品，对实现甘薯渣高值化利用、减少环境污染、丰富甘薯加工产品种类等具有重要意义。本文综述了国内外关于 甘薯渣发酵及高值化利用的研究进展，并对其存在的问题及未来发展趋势等进行了总结与展望，旨在为甘薯渣发酵及高值化利用提供理论依据。

Research progress on high value fermentation transformation and utilization of Ipomoea batatas Lam. residue

China has the largest sweetpotato planting area and output in the world. Sweetpotatoes are mainly used for the production of starch and thereof products. In this process, a large amount of sweetpotato residue generatedand often discarded directly, resulting in serious resources waste and environmental pollution. Due to its richness in starch, dietary fiber, protein and other nutrients, sweetpotato residue can be converted into high value-added products such as dietary fiber, ethanol and single-cell protein by microbial fermentation. It is of great significance for achieving high-value utilization of sweetpotato residue, which not only reduces environmental pollution but also enriches the variety of sweetpotato processed products. This paper reviewed the worldwide research progress in high-value utilization of sweetpotato residue by fermentation, summarized the existing problems and future perspectives, which provides a theoretical basis for high-value utilization of sweetpotato residue by fermentation.
