Sweet potato (Ipomoea batatas L.) is among the major food crops in the world and is cultivated in all tropical and subtropical regions particularly in Asia, Africa, and the Pacific. Asia and Africa regions account for 95% of the world's production. Among the root and tuber crops grown in the world, sweet potato ranks second after cassava. In previous decades, sweet potato represented food and feed security, now it offers income generation possibilities, through bioprocessing products. Bioprocessing of sweet potato offers novel opportunities to commercialize this crop by developing a number of functional foods and beverages such as sour starch, lacto-pickle, lacto-juice, soy sauce, acidophilus milk, sweet potato curd and yogurt, and alcoholic drinks through either solid state or submerged fermentation. Sweet potato tops, especially leaves are preserved as hay or silage. Sweet potato flour and bagassae are used as substrates for production of microbial protein, enzymes, organic acids, monosodium glutamate, chitosan, etc. Additionally, sweet potato is a promising candidate for production of bioethanol. This review deals with the development of various products from sweet potato by application of bioprocessing technology. To the best of our knowledge, there is no review paper on the potential impacts of the sweet potato bioprocessing.
甘薯（Ipomoea batatas L.）是世界上主要的粮食作物之一，在所有热带和亚热带地区，特别是亚洲、非洲和太平洋地区都有种植。亚洲和非洲地区占世界产量的 95%。在世界上种植的根茎作物中，甘薯仅次于木薯。在过去几十年中，甘薯不仅是粮食和饲料安全的保障，而且通过生物加工产品为创造收入提供了可能。甘薯的生物加工为开发各种功能性食品和饮料（如酸淀粉、乳酸泡菜、乳酸汁、酱油、嗜酸乳、甘薯豆腐和酸奶、酒精饮料）提供了新的商机，这些产品可以通过固态或液态发酵来实现。甘薯的顶部，特别是叶子被保存为干草或青贮饲料。甘薯粉和甘蔗渣被用作生产微生物蛋白、酶、有机酸、谷氨酸钠、壳聚糖等的基质。此外，甘薯是生产生物乙醇的有前途的候选作物。本综述介绍了通过应用生物加工技术从甘薯中开发各种产品的情况。据我们所知，目前还没有关于甘薯生物加工潜在影响的综述文章。
