●兵团日报常驻记者 冯晓玲 通讯员 高天 韩珊珊 2月5日清晨6时许，晨光熹微，寒意未消，新疆九鼎农产品批发中心（以下简称"九鼎市场"）内早已被 此起彼伏的装卸声、车辆轰鸣声唤醒。冷链物流车川流不息，进场货车有序装卸，提货商户推着推车在 车流间穿梭。人群中，新疆九鼎检测技术有限公司采样员刘国星和孟微格外显眼，他们身着印有"九鼎 检测"字样的黄黑色工装，骑着电动三轮车，手持采样设备，循着溯源平台打码机的荧光指示，有条不 紊地进行采样工作。 "师傅，我们做个采样检测，很快就好！"蔬菜交易区里，一辆满载云南昆明黄瓜的货车刚停稳，刘国星 和孟微便迅速拿出设备，快速打印出专属溯源标签，娴熟地贴在样品上，再抽取样品装入密封袋，整套 动作行云流水，全程不过几分钟。 "市场的检测制度，既是对老百姓负责，也是在帮我们商户规避风险。"从事蔬菜批发多年的商户李保华 谈起市场的安全管控，他连连称赞，"以前最怕货物因不合格被销毁，现在进场必检、全程溯源，我们 卖得放心，群众买得也安心。" 打开一张样品溯源标签，摊位号、品类、车牌号、进货时间、承运车辆等关键信息一目了然，这相当于 给每一批农产品办了一张"身份证"。采样过程中，他们采用随 ...

Core Viewpoint - Agricultural product quality safety is the first line of defense for food safety, with agricultural product inspection laboratories being the core battleground to safeguard this line [2][3]. Group 1: Importance of Inspection Laboratories - Agricultural product inspection laboratories are essential for accurately controlling key indicators such as composition, harmful substance residues, and physicochemical properties [2][3]. Group 2: Common Instruments and Their Uses - pH Meter: Measures pH value [4] - Conductivity Meter: Measures the conductivity of electrolyte solutions [4] - Liquid Chromatograph: Qualitative and quantitative analysis [4] - Gas Chromatograph: Qualitative and quantitative analysis [4] - Automatic Potentiometric Titrator: Acid-base, redox, precipitation, and complex titrations [4] - UV-Visible Spectrophotometer: Measures the absorption of substances at different wavelengths for quantitative analysis [4] - Atomic Absorption Spectrophotometer: Quantitative analysis based on the absorption of characteristic radiation by ground state atoms [4] - Karl Fischer Moisture Meter: Measures moisture content [4] - Fourier Transform Infrared Spectrometer: Qualitative and quantitative analysis [4] - Colorimeter: Measures the color of agricultural products [4] Group 3: Additional Instruments - Ion Chromatograph: Qualitative analysis [5] - Fluorescence Spectrophotometer: Measurement of elements that easily form hydrides or gaseous components [5] - Refractometer: Measures refractive index [5] - Kjeldahl Nitrogen Analyzer: Measures nitrogen content in proteins [5] - Mycotoxin Testing Instruments: Measures aflatoxin content [6] - Sulfur Dioxide Testing Instruments: Measures sulfur dioxide concentration [6] - Fiber Analyzer: Measures fiber content [6] - Fat Analyzer: Measures fat content [6] Group 4: Comprehensive Detection System - The instruments cover basic physicochemical indicators (e.g., pH, moisture, sugar content), critical safety indicators (e.g., pesticide residues, aflatoxins, heavy metals), and nutritional components (e.g., amino acids, fats, fibers), creating a comprehensive detection system [6].

Core Viewpoint - The competition aims to enhance the skills of agricultural product quality safety testing personnel in Shandong Province, contributing to the overall agricultural quality and safety standards in the region [1] Group 1: Competition Overview - The 2025 Shandong Province Agricultural Product Quality Safety Testing Skills Competition is part of the provincial selection for the National Agricultural Industry Vocational Skills Competition [1] - The event is organized by the Shandong Provincial Department of Agriculture and Rural Affairs, the Provincial Federation of Trade Unions, and the Provincial Animal Husbandry Bureau, with the Shandong Academy of Agricultural Sciences as the host [1] Group 2: Objectives and Impact - The competition serves as a comprehensive review of the agricultural product quality safety testing system in the province, promoting learning, practice, and application through competitive events [1] - It aims to motivate testing personnel to enhance their skills and knowledge, thereby ensuring food safety for the public and strengthening the agricultural product quality safety defense [1] Group 3: Current Infrastructure - Shandong Province currently has over 160 agricultural product quality testing institutions certified through metrology certification and institutional assessment [1] - The testing team structure includes provincial and municipal testing centers as the main bodies, supplemented by third-party testing institutions, providing robust technical support for agricultural product quality safety [1]

Core Viewpoint - The Guangdong Academy of Agricultural Sciences has led the drafting of two national standards for feed testing, which will be implemented on February 1, 2026, enhancing the standardization system of the feed industry in China [2][5][11]. Group 1: New Standards - The two new national standards are GB/T 21108-2025 for the determination of chloramphenicol, thiamphenicol, and florfenicol in feed using high-performance liquid chromatography-tandem mass spectrometry, and GB/T 22262-2025 for the determination of chlorohydroxy pyridine in feed [3][4][8][9]. - These standards will provide technical support for regulatory authorities to ensure that feed products meet health and safety requirements, promoting industry development and enhancing market competitiveness [11][12]. Group 2: Research and Development - The Quality Standards and Monitoring Technology Research Institute has been dedicated to agricultural product quality safety, standardization research, and evaluation technology, having completed the drafting and revision of over 190 national, industry, and local standards [13][14]. - The institute plans to continue its research on standardization of detection technologies for agricultural products and inputs, providing technical and standardized support for high-quality agricultural development [16].
