“民以食為天,食品安全為重”。食品安全經常影響成千上萬的父母;看似簡單瑣碎的工作往往是事故的溫床。目前,數以百計的學校食堂都配備了快速檢查室,在上菜前檢查蔬菜。作為農藥殘留檢測中*重要的部分,如何更好地檢測農藥殘留?食堂設立快速檢查室--農藥殘留檢測儀,大(da)(da)大(da)(da)降低了食品安全問(wen)題發生的概率(lv)。
農(nong)藥(yao)殘留快速(su)檢(jian)測(ce)(ce)設備(bei)可用于蔬菜(cai)、水(shui)果等農(nong)產(chan)品(pin)(pin)(pin)(pin)中有(you)機磷和氨基(ji)甲酸酯類農(nong)藥(yao)的(de)(de)含量(liang)檢(jian)測(ce)(ce)。一旦發現食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)安(an)全問題(ti),利用快速(su)檢(jian)測(ce)(ce)設施和設備(bei),學校食(shi)(shi)(shi)(shi)(shi)堂(tang)可以立即(ji)對(dui)相關食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)進(jin)行控制,及時、快速(su)、有(you)效地控制食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)安(an)全風險(xian),大大提(ti)高了對(dui)潛在(zai)食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)安(an)全隱患(huan)的(de)(de)篩查(cha)能(neng)力。該(gai)檢(jian)測(ce)(ce)方法簡單,能(neng)滿足食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)市場(chang)對(dui)食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)安(an)全檢(jian)測(ce)(ce)的(de)(de)需求。農(nong)藥(yao)殘留檢(jian)測(ce)(ce)儀在(zai)快餐食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)檢(jian)測(ce)(ce)中起著重要的(de)(de)作用。食(shi)(shi)(shi)(shi)(shi)堂(tang)工(gong)作人(ren)員可自行操(cao)作,為各類食(shi)(shi)(shi)(shi)(shi)品(pin)(pin)(pin)(pin)提(ti)供快速(su)、快捷的(de)(de)檢(jian)驗(yan)服務(wu)。
根據(ju)酶抑制(zhi)法原理(li),在一定條件下,有機(ji)(ji)磷和氨基甲酸(suan)類(lei)(lei)農(nong)藥會對(dui)膽(dan)堿酯酶的(de)正(zheng)常(chang)功能產生明顯地抑制(zhi)作用,其抑制(zhi)率與農(nong)藥的(de)濃度(du)(du)呈正(zheng)相關。正(zheng)常(chang)情況下,酶催化神經傳導(dao)代謝產物乙酰膽(dan)堿水(shui)解(jie),其水(shui)解(jie)產物與顯色劑反(fan)應,產生黃色物質,通過(guo)分光(guang)(guang)光(guang)(guang)度(du)(du)計測定410nm下吸光(guang)(guang)度(du)(du)隨時間(jian)變(bian)化的(de)數值,經過(guo)計算后即可(ke)得出(chu)抑制(zhi)率,通過(guo)抑制(zhi)率可(ke)以快(kuai)速判(pan)斷出(chu)樣品中有機(ji)(ji)磷和氨基甲酸(suan)類(lei)(lei)農(nong)藥的(de)殘留(liu)情況。
蔬(shu)菜(cai)、水果(guo)農藥殘留檢(jian)(jian)(jian)測(ce)(ce)(ce)的(de)(de)質(zhi)量控(kong)制(zhi)措施需(xu)要(yao)引(yin)起檢(jian)(jian)(jian)測(ce)(ce)(ce)人員的(de)(de)重(zhong)視(shi)。檢(jian)(jian)(jian)測(ce)(ce)(ce)人員需(xu)要(yao)根據相關標準和規范,明確(que)蔬(shu)菜(cai)水果(guo)農藥殘留檢(jian)(jian)(jian)測(ce)(ce)(ce)的(de)(de)重(zhong)點(dian),將質(zhi)量控(kong)制(zhi)措施應用(yong)到(dao)蔬(shu)菜(cai)水果(guo)農藥殘留檢(jian)(jian)(jian)測(ce)(ce)(ce)的(de)(de)全過程,從制(zhi)備階段開始(shi),包括(kuo)檢(jian)(jian)(jian)測(ce)(ce)(ce)溶(rong)液的(de)(de)配(pei)制(zhi)、檢(jian)(jian)(jian)測(ce)(ce)(ce)過程和檢(jian)(jian)(jian)測(ce)(ce)(ce)結果(guo)的(de)(de)處理,整(zheng)體提高蔬(shu)菜(cai)水果(guo)農藥檢(jian)(jian)(jian)測(ce)(ce)(ce)質(zhi)量,保障食品安全。
