This paper is set against the backdrop of the flawed regulatory system environment currently present in China. It uses the vertical differentiation model under incomplete information from industrial organization theory as its theoretical foundation and employs game theory methods to examine the quality decision-making behaviors of low-quality and high-quality firms at the Nash equilibrium. Additionally, it utilizes the zero-inflated Poisson regression model to investigate the impact of raising the minimum quality standard on food safety and passed a series of robustness tests, using data from provincial and municipal statistical yearbooks (2014–2019) and the compliance rate of meat food safety surveillance sampling. The study finds that: (1) Moderately increasing the minimum quality standard can improve the level of food safety. (2) When the minimum quality standard is significantly raised, the strength of government regulation has a “U-shaped” moderating effect on the relationship between the increase in the minimum quality standard and the level of food safety. That is, when government regulation is weak, making the cost of penalties lower than the benefits of breaking the law, a significant increase in the minimum quality standard will reduce the level of food safety; when government regulation is strong, making the cost of penalties higher than the benefits of breaking the law, a significant increase in the minimum quality standard will improve the level of food safety.","食品安全标准被视为一种公共最低质量标准，作为各国政府广泛采用的规制工具之一，是保障食品安全的重要前提。本文以当前我国规制制度环境尚不健全为背景，以产业组织理论中不完全信息条件下的纵向差异化模型为理论基础，运用博弈论方法考察了纳什均衡下低质量企业与高质量企业的质量决策行为，并利用零膨胀泊松回归模型，基于2014—2019年省市级统计年鉴数据及肉类食品安全监督抽检合格率，探究了最低质量标准提升对食品安全的影响，且通过了一系列稳健性检验。研究发现：（1）适度提高最低质量标准能够提升食品安全水平。（2）当最低质量标准显著提高时，政府规制强度对最低质量标准提升与食品安全水平之间的关系具有“U型”调节效应。即当政府规制较弱，使得惩罚成本低于违法收益时，最低质量标准的显著提升会降低食品安全水平；当政府规制较强，使得惩罚成本高于违法收益时，最低质量标准的显著提升则会提高食品安全水平。",null,"Frontiers in Sustainable Food Systems","2026-09-08T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"主题为食品安全标准与监管，不属于三农、农业信息化、智慧农业、数字乡村或农业科技范畴。",[19],{"name":10,"url":6},[21],"食品安全",[],{"status":24,"locked":14,"version":25,"method":26,"evidence":27},"needs_review","2026-10-22.2","rules",{"candidates":28,"agricultural_evidence":14,"reason":37},[29],{"code":30,"score":31,"supported":32,"title":33,"abstract":35,"tags":36},"E4",15,true,[34],"food safety",[21,34],[21],"农业相关性需要复核",[],"Theimprovementofminimumqualitystandardsa-1883",1,"10.3389\u002Ffsufs.2026.1931446",{"doi":41,"openalex_id":43,"authors":44,"venue":10,"cited_by_count":15,"oa_url":6,"card":55,"direction":59,"ingested_from":61},"W7211890694",[45,48,50,52],{"name":46,"orcid":47},"Shufen Tang","https:\u002F\u002Forcid.org\u002F0000-0002-6948-9065",{"name":49,"orcid":9},"Abduweli Mehepula",{"name":51,"orcid":9},"Taiping Li",{"name":53,"orcid":54},"Yuqing Zheng","https:\u002F\u002Forcid.org\u002F0000-0002-9812-5404",{"tldr":56,"method":57,"finding":58,"direction":59,"opportunity":60},"研究提高最低质量标准对食品安全的影响，发现适度提高可改善食品安全，但大幅提高需强监管配合。","运用博弈论垂直差异化模型和零膨胀泊松回归，分析2014-2019年省级数据。","适度提高最低质量标准提升食品安全；大幅提高时，政府监管强度呈U型调节作用。","农业绿色发展与碳","可探索不同监管强度下最优质量标准设定，结合中国实际监管环境，为政策制定提供动态优化建议。","openalex","2026-09-08T23:30:06.530871Z",{"total":64,"page":40,"page_size":64,"items":65},6,[66,100,204,247,310,401],{"id":67,"title":68,"url":69,"summary":70,"summary_zh":9,"content":71,"source_name":72,"source_url":9,"published_at":73,"category":74,"cover_url":9,"hotness":13,"is_selected":14,"score":75,"score_detail":76,"sources":82,"tags":84,"primary_topic":9,"secondary_topics":89,"classification":90,"search_phrases":95,"slug":98,"view_count":15,"doi":9,"paper":9,"created_at":99},5524,"广东农科院质标所牵头地方标准获广东标准化创新发展大比武银奖","https:\u002F\u002Fwww.gdaas.cn\u002Fysdtn\u002Fkyjz\u002Fcontent\u002Fpost_1340862.html","质标所牵头制定的广东省地方标准《粤菜预制菜包装标识通用要求》（DB44\u002FT 2602—2025）获2026广东省标准化创新发展「大比武」银奖。该标准是全国首个粤菜预制菜包装标识省级地方标准，联合26家预制菜代表企事业单位制定，规定包装选材、安全设计与减量化管控，细化标签标识规则并鼓励增设粤菜文化二维码与追溯码。","近日，2026广东省标准化创新发展“大比武”获奖名单正式公布，我院质标所牵头制定的广东省地方标准《粤菜预制菜包装标识通用要求》（DB44\u002FT 2602—2025）获银奖，并在“广东省2026年世界标准日宣传活动”中进行获奖展示。该标准是全国首个粤菜预制菜包装标识省级地方标准，是我院质标所预制菜标准化研究的重要成果，标志我省预制菜标准体系建设迈上新台阶。\n\n本次“大比武”由广东省市场监督管理局主办，旨在深入贯彻《国家标准化发展纲要》及省委、省政府关于发挥标准引领作用促进高质量发展的部署要求，以“标准领航赋能高质量发展”为主题，面向全省有关单位主导制定的国家标准和广东省级地方标准，聚焦智能家电家居、现代农业两大领域开展比拼。经报名征集、初赛评审、专业核验、决赛答辩等环节角逐，每个领域仅设金奖2项、银奖4项、优秀奖6项，竞争激烈、荣誉分量十足。\n\n该标准由我院质标所牵头，联合26家预制菜代表企事业单位、汇集产学研多方力量制定，于2025年1月发布、4月实施。标准立足广府菜、客家菜、潮菜等粤菜产业实际，对预制菜包装选材、安全设计、减量化管控作出系统性规定；同时细化标签标识规则，明确产品需标注“预制菜”或“预制菜肴”，标明主要原料投料量、烹饪食用方法、贮存条件等关键信息，鼓励增设粤菜文化二维码、食品安全追溯码、反对浪费提示等内容，为企业生产规范、市场监督执法提供清晰技术支撑，兼顾食品安全、产业发展与粤菜文化传播，有效带动了粤菜预制菜产业的标准化、规范化发展。","广东省农业科学院 2026-10-19","2026-10-19T00:00:00Z","报道",70,{"impact":77,"substance":78,"depth":31,"authority":79,"freshness":80,"relevant":40,"comment":81},18,20,12,5,"全国首个粤菜预制菜包装标识省级地方标准获省级标准化奖项，属细分行业标准化实质进展，具备产业参考价值。",[83],{"name":72,"url":69},[21,85,86,87,88],"地方标准","预制菜","粤菜","包装标识",[],{"status":91,"locked":14,"version":25,"method":26,"evidence":92},"unclassified",{"candidates":93,"agricultural_evidence":32,"reason":94},[],"缺少足够的主题证据",[96,97],"粤菜预制菜 包装标识 地方标准","广东农科院 质标所 预制菜","粤菜预制菜包装标识地方标准-5524","2026-10-22T00:07:04.669455Z",{"id":101,"title":102,"url":103,"summary":104,"summary_zh":105,"content":9,"source_name":106,"source_url":103,"published_at":73,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":107,"score_detail":108,"sources":113,"tags":115,"primary_topic":120,"secondary_topics":126,"classification":132,"search_phrases":176,"slug":179,"view_count":15,"doi":180,"paper":181,"created_at":203},5400,"Artificial intelligence in food safety: a bibliometric and empirical synthesis of emerging technologies and research frontiers","https:\u002F\u002Fdoi.org\u002F10.1108\u002Fbfj-06-2025-0819","Purpose This study aimed to identify recent research trends in the integration of artificial intelligence (AI) with food safety and security through a comprehensive bibliometric analysis.

This research develops a closed-loop environmental control system, utilizing an Arduino Mega 2560 microcontroller to actively manage the microclimate within a semi-automatic cultivation machine. The system integrates thermoelectric (Peltier) cooling to effectively dissipate accumulated metabolic heat, combined with a precision humidity control mechanism. Performance was evaluated in triplicate (n = 3) against traditional timer-based irrigation systems. Statistical analysis (one-way ANOVA, p \u003C 0.05) demonstrated that the prototype successfully stabilized water temperature (22–25 °C) and relative humidity (80–90%) throughout the cultivation period. These optimal conditions led to a 31–65% increase in total net yield compared to traditional chemical-free methods. While this yield remains slightly lower than intensive commercial practices that rely on growth-accelerating chemicals, laboratory tests by an ISO\u002FIEC 17025 accredited facility confirmed undetectable levels of formaldehyde and sulfur dioxide.

Hence, single element toxicity assessment does not provide realistic assessment of its exposure. The present review summarizes research on chromium behaviour along the soil, root, stalk and cane juice in sugarcane. Cr mobility depends on soil pH and redox potential (Eh), while salinity adds an additional control through ionic strength and chloride complexation. Sequential extraction and speciation analysis prove that bioavailable fraction is more important for plant toxicity than total Cr concentration. Cr(VI) enters roots via sulphate and phosphate transporters via mimicking oxyanions and this mechanism differs from that of other metal ions that use ion channels, a route that salt-induced PHT1 expression could plausibly modulate, although this has not been tested in sugarcane. In proxy species, combined Cr and salinity exposure raises reactive oxygen species production and membrane damage beyond the level induced by either stress alone, whereas in sugarcane the downregulation of PEP carboxylase, pyruvate orthophosphate dikinase and photosystem proteins has so far been documented only under salinity applied by itself. Whether the two stresses interact on C4 carbon assimilation in cane remains untested. Root-to-stalk transfer of Cr is low at most sites examined, but not at all of them, and measurable Cr reaches cane juice at concentrations that have driven hazard quotients above unity in two of the four field studies assessed. Bagasse biochar, biochar with nZVI, halotolerant Cr-reducing microorganisms and water management based on redox reactions all reduce Cr bioavailability, but field experiments in cane are lacking. Factorial experiments investigating Cr behaviour depending on salinity gradient, juice level speciation and field trials in ratoons are required.","甘蔗土壤中的铬污染通常与制革废水、电镀废水、造纸厂废水、酒糟灌溉和滤泥带入的伴生金属及盐分复合存在。因此，单一元素毒性评估无法对其暴露状况作出符合实际的评价。本文综述了铬在甘蔗土壤、根系、茎秆及蔗汁中行为的研究进展。铬的迁移性取决于土壤pH和氧化还原电位（Eh），而盐分通过离子强度和氯络合作用对其施加额外调控。连续提取和形态分析表明，生物有效态组分对植物毒性的意义大于总铬浓度。Cr(VI)通过模拟含氧阴离子经硫酸盐和磷酸盐转运蛋白进入根系，这一机制不同于其他利用离子通道的金属离子，而盐诱导的PHT1表达可能调控该途径，但尚未在甘蔗中验证。在替代物种中，铬与盐分复合暴露引起的活性氧产生和膜损伤超过单一胁迫诱导的水平，而在甘蔗中，磷酸烯醇式丙酮酸羧化酶、丙酮酸磷酸双激酶和光系统蛋白的下调目前仅在单独盐胁迫下得到证实。两种胁迫是否在甘蔗C4碳同化过程中发生交互作用仍未经检验。在多数已考察的位点，铬从根系向茎秆的转移量较低，但并非所有位点均如此；在所评估的四项田间研究中，有两项显示可检测到的铬到达蔗汁，其浓度已使危害商数超过1。蔗渣生物炭、负载纳米零价铁（nZVI）的生物炭、耐盐铬还原微生物以及基于氧化还原反应的水分管理均可降低铬的生物有效性，但甘蔗田间试验尚属缺乏。有必要开展考察铬行为随盐度梯度变化的析因实验、蔗汁水平上的形态分析以及宿根蔗田间试验。",74,{"impact":79,"substance":109,"depth":77,"authority":318,"freshness":260,"relevant":40,"comment":319},13,"综述系统梳理铬-盐交互、食物链迁移与阻控手段，指出甘蔗田间试验空白，对污染蔗区安全利用有参考价值，但属机理综述、非产业级突破。",[321],{"name":10,"url":313},[323,21,324,325,326],"甘蔗","盐渍化","土壤重金属","生物炭修复",{"code":328,"slug":329,"name":330,"path":331,"parent_code":332},"A6","cash-crops","棉麻糖与特色经作","\u002Ftopic\u002Ffield-crops\u002Fcash-crops","A",[334],{"code":335,"slug":336,"name":337,"path":338,"parent_code":339},"H2","soil","土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil","H",{"status":133,"locked":14,"version":25,"method":26,"evidence":341},{"candidates":342,"agricultural_evidence":32},[343,348,353,358,362],{"code":328,"score":31,"supported":32,"title":344,"abstract":346,"tags":347},[345],"sugarcane",[323,345],[323],{"code":335,"score":111,"supported":32,"title":349,"abstract":350,"tags":352},[],[351,336],"土壤",[325,324],{"code":231,"score":166,"supported":32,"title":354,"abstract":355,"tags":357},[],[356],"fertigation",[],{"code":285,"score":166,"supported":32,"title":359,"abstract":360,"tags":361},[],[288],[],{"code":30,"score":40,"supported":14,"title":363,"abstract":364,"tags":365},[],[],[21],[367,368],"甘蔗 铬污染 盐渍化","甘蔗汁 风险","甘蔗铬污染盐渍化-4797","10.3389\u002Ffsufs.2026.1942892",{"doi":370,"openalex_id":372,"authors":373,"venue":10,"cited_by_count":15,"oa_url":313,"card":395,"direction":59,"ingested_from":61},"W7221577366",[374,377,379,381,383,385,387,389,391,393],{"name":375,"orcid":376},"Gowtham Sornam","https:\u002F\u002Forcid.org\u002F0009-0009-1150-1568",{"name":378,"orcid":9},"Sugumaran Melkumaramangalam Palani",{"name":380,"orcid":9},"Parameswari Ettiyagounder",{"name":382,"orcid":9},"Kalaiselvi Thangavel",{"name":384,"orcid":9},"Saravanan Naaganoor Ananthan",{"name":386,"orcid":9},"Elayarajan Maharajan",{"name":388,"orcid":9},"Selva Kumar Manikkam",{"name":390,"orcid":9},"Sassikumar Datchinamoorthy",{"name":392,"orcid":9},"Sinduja Murugaiyan",{"name":394,"orcid":9},"Priyatharsini Sengottaiyan",{"tldr":396,"method":397,"finding":398,"direction":59,"opportunity":399},"综述甘蔗农业生态系统中铬与盐分交互作用、食物链传递及缓解措施，指出单元素毒性评估不足。","综述土壤-根-茎-汁中铬形态、转运与缓解技术，结合顺序提取与形态分析。","铬与盐分交互对C4碳同化影响未测，蔗汁铬危害商在部分田间研究中超1，缓解技术缺乏田间验证。","可开展盐度梯度下铬形态与C4光合交互的因子实验，并验证生物炭等缓解措施的田间效果。","2026-10-13T23:30:07.200287Z",{"id":402,"title":403,"url":404,"summary":405,"summary_zh":406,"content":9,"source_name":10,"source_url":404,"published_at":407,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":211,"score_detail":408,"sources":410,"tags":412,"primary_topic":417,"secondary_topics":422,"classification":424,"search_phrases":443,"slug":446,"view_count":15,"doi":447,"paper":448,"created_at":474},4737,"Integrated assessment of agricultural and processing-related chemical hazards across the food chain: glyphosate occurrence and lipid changes in ready-to-eat corn-based foods","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1960698","Introduction Ready-to-eat foods may accumulate chemical hazards from both agricultural production and food processing. These hazards converge in the same food but are usually evaluated separately. This study assessed both types of hazard together in corn-based foods consumed on a Mexican university campus, as an integrated food-chain approach. Methods Ten tortilla and ten tortilla chip samples were collected from campus cafeterias and food stalls. They were screened for glyphosate by high-performance liquid chromatography with diode-array detection (HPLC-DAD), as an indicator of agricultural chemical hazards. Dietary exposure was estimated with a conservative upper-bound scenario and expressed as a hazard quotient (HQ) relative to the acceptable daily intake (ADI). Six paired frying-oil samples, collected before and after frying, were analyzed by Fourier-transform infrared spectroscopy (FTIR) to estimate iodine value (IV) as an indicator of lipid unsaturation. Results Glyphosate signals were detected in 8\u002F10 tortilla and 10\u002F10 tortilla chip samples (90% overall). Screening-level concentrations ranged from 0.107 to 1.994 mg kg −1 . Detected concentrations were above the Mexican maximum residue limit (MRL) for corn grain (0.1 mg kg −1 ) and below the Codex Alimentarius MRL for maize (5 mg kg −1 ); both limits were used only as regulatory reference points. HQ values were 0.0573 for women and 0.0511 for men, so estimated exposure was below the ADI under the assumed scenario. IV decreased significantly after frying (mean decrease 5.00 units; 95% CI 1.30–8.71; p = 0.0178). Discussion Ready-to-eat corn-based foods may carry both agricultural residues and processing-related lipid changes. HQ \u003C 1 does not imply absence of risk. The frequent detection of glyphosate supports continued monitoring and confirmatory analysis by liquid chromatography–tandem mass spectrometry (LC–MS\u002FMS). This integrated approach can support food safety surveillance in institutional food environments.","引言 即食食品可能同时积累来自农业生产的化学危害和来自食品加工的化学危害。这些危害汇聚于同一食品中，但通常被分别评估。本研究以墨西哥某大学校园内消费的玉米基食品为对象，采用食物链综合方法对这两类危害进行了联合评估。方法 从校园食堂和食品摊位采集了10份玉米饼和10份玉米片样品。采用高效液相色谱-二极管阵列检测法（HPLC-DAD）筛查草甘膦，作为农业化学危害的指标。膳食暴露量采用保守的上限情景进行估算，并以相对于可接受每日摄入量（ADI）的危害商（HQ）表示。采集了6对煎炸前后配对的煎炸油样品，通过傅里叶变换红外光谱（FTIR）分析，估算碘值（IV）作为脂质不饱和度的指标。结果 在8\u002F10份玉米饼和10\u002F10份玉米片样品中检测到草甘膦信号（总体90%）。筛查水平浓度范围为0.107至1.994 mg kg⁻¹。检出浓度高于墨西哥玉米粒最大残留限量（MRL）（0.1 mg kg⁻¹），低于国际食品法典委员会玉米最大残留限量（5 mg kg⁻¹）；两个限量仅用作监管参考点。女性的HQ值为0.0573，男性为0.0511，因此在假设情景下估算暴露量低于ADI。煎炸后IV显著下降（平均下降5.00个单位；95% CI 1.30–8.71；p = 0.0178）。讨论 即食玉米基食品可能同时携带农业残留物和加工相关的脂质变化。HQ \u003C 1并不意味着不存在风险。草甘膦的频繁检出支持继续开展监测，并通过液相色谱-串联质谱法（LC–MS\u002FMS）进行确证分析。这种综合方法可支持机构食品环境中的食品安全监督。","2026-10-11T00:00:00Z",{"impact":111,"substance":258,"depth":259,"authority":318,"freshness":260,"relevant":40,"comment":409},"该研究以食品链整合视角同时评估农业投入品残留与加工过程脂质变化，方法新颖、数据具体，对食品安全监测有参考价值，但属境外校园小样本研究，产业影响有限。",[411],{"name":10,"url":404},[21,413,414,415,416],"农药残留","玉米制品","膳食暴露评估","食品链",{"code":418,"slug":419,"name":420,"path":421,"parent_code":332},"A3","maize","玉米","\u002Ftopic\u002Ffield-crops\u002Fmaize",[423],{"code":30,"slug":128,"name":129,"path":130,"parent_code":131},{"status":133,"locked":14,"version":25,"method":26,"evidence":425},{"candidates":426,"agricultural_evidence":32},[427,432,436],{"code":418,"score":259,"supported":32,"title":428,"abstract":430,"tags":431},[429],"corn",[420,419,429],[],{"code":30,"score":111,"supported":32,"title":433,"abstract":434,"tags":435},[],[21,34],[413,21],{"code":437,"score":64,"supported":32,"title":438,"abstract":439,"tags":442},"E1",[],[440,441],"食品加工","food processing",[],[444,445],"墨西哥 玉米饼 草甘膦","即食玉米食品 农药残留","墨西哥玉米饼草甘膦-4737","10.3389\u002Ffsufs.2026.1960698",{"doi":447,"openalex_id":449,"authors":450,"venue":10,"cited_by_count":15,"oa_url":404,"card":469,"direction":59,"ingested_from":61},"W7221452266",[451,453,455,457,460,463,466],{"name":452,"orcid":9},"Wendy Jannette Ascencio-López",{"name":454,"orcid":9},"María Teresa Zayas-Pérez",{"name":456,"orcid":9},"T.
