Abstract: This article briefly introduces the current status of rapid detection of pesticide residues in vegetables and fruits, summarizes the promotion measures of colloidal gold immunochromatography technology, and analyzes the existing problems such as lack of unified standards, uneven professional quality of grassroots staff, and lack of effective application of rapid detection results. Corresponding countermeasures are proposed to provide assistance for the further promotion and application of colloidal gold immunochromatography technology.
Keywords: colloidal gold immunochromatography; quality and safety of agricultural products; pesticide residue
1 蔬果中農(nóng)藥殘留快速檢測技術(shù)現(xiàn)狀
1.1 酶抑制法
酶抑制法是利用特定種類農(nóng)藥對動物體內(nèi)乙酰膽堿酶(Acetylcholinesterase,AchE)具有抑制作用的原理,用目測顏色變化或分光光度計測定吸光度值,對農(nóng)藥殘留的情況做出判斷。(剩余3758字)
