我国甘薯质量安全现状分析及对策建议OA

[Objective]To analyze the quality and safety risks of sweet potato and its edible leaves throughout the entire industry chain in China,and to identify the major risk links and risk factors,providing a basis for qual-ity and safety control.[Method]The literature analysis method and inductive approach were used to review relevant studies on sweet potato cultivation,postharvest handling,processing,and distribution in China,with a focus on production environments,seedling quality,contamination risks of storage roots and sweet potato leaves,natural risk factors,processing procedures,and standard systems.[Result]Quality and safety risks of sweet potato are diverse in origin and characterized by cross-link transmission.As underground storage roots remain in contact with soil for a long period,contaminants such as heavy metals and pesticide residues can enter and accumulate in storage roots through root uptake,with their risks affected by soil conditions,cultivar characteristics,and cultivation practices.As an edible part,sweet potato leaves are continuously exposed to field environments and are susceptible to external contaminants such as pesticide deposition and heavy metal deposition,presenting safety risks different from those of storage roots.During production,pesticide residues,postharvest chemical treatments,and previous crop residues remain prominent concerns,while virus-carrying seedlings increase disease risks.Postharvest diseases and low-temperature stress may induce the formation of natural risk factors such as furanoterpenoids.In addition,the generation of hazardous substances such as acrylamide during processing,insufficient cold chain conditions,and migration of substances from packaging materials may also affect product safety.Although the current standard system covers some traditional contaminant limits and production management requirements,evaluation methods for sweet potato leaf safety,sweet potato-specific natural risks,and emerging contaminants remain insufficient.[Conclusion]Quality and safety management of sweet potato should consider the safety of both storage roots and edible leaves,strengthen risk control throughout the entire industry chain,improve relevant standard systems,enhance detection,evaluation,and regulatory capabilities,and ensure the quality and safety of sweet potato products.
