甘薯茎叶研究与利用进展

Progress on Research and Utilization of Sweetpotato Vines and Leaves

甘薯茎叶富含蛋白质、维生素、膳食纤维、矿物质等营养成分,具有抗氧化、调节血脂等多个保健功能,可作为叶菜、饲料来源.另外甘薯茎叶具有丰富多彩的叶色和变化多样的叶型,具有观赏和园林绿化等商业价值.甘薯茎叶研究基础较为薄弱,主要集中于营养、生理活性成分等研究,而分子遗传、加工利用等相关研究起步较晚.系统梳理了甘薯茎叶的基础研究进程,并从叶菜、观赏、食品加工、饲用等多个方面分析了甘薯茎叶的利用进展.针对研究与利用现状及存在的不足,提出了针对性的建议与展望,为后续甘薯茎叶相关研究及产业发展提供参考.

Sweetpotato vines and leaves(SPVL)are rich in protein,vitamins,dietary fiber,minerals and other nutrients,and own multiple healthcare function such as antioxidation and regulating blood lipid,which can be used as a high-quality source of leafy vegetables and forage.In addition,because of its leaf with various colors and leaf shapes,it also has commercial values of ornamental horticulture.The basic research related to the SPVL is rare,mainly focusing on the study of nutritional and physiological active components,while the research on molecular genetics,processing and utilization was started late.This paper systematically reviews the basic research progress of SPVL,and expounds the progress of SPVL utilization from leaf vegetables,ornamental,food processing,feed utilization and other aspects.In view of the current situation and shortcomings of research and utilization,the authors put forward targeted opinions and forecast to provide reference for the follow-up research on SPVL and the development of related industries.
