中文摘要:

      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发酵甘薯渣制备膳食纤维、低聚糖、乙醇、有机酸和单细胞蛋白等高附加值产品的研究进展, 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。

英文摘要:

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