產(chǎn)品名稱：食用油過氧化值檢測儀 產(chǎn)品型號：SGA8

食用油過氧化值檢測儀型號：SGA8

過氧化值檢測儀SGA8通道過氧化值檢測儀能夠快速檢測食用油（豆油、芝麻油、花生油、玉米油等）以及食品類中的過氧化值含量；于植物油（豆油、芝麻油、花生油、玉米油等）品質(zhì)的鑒別檢驗。符合《GB/T5009.37—2003 食用植物油衛(wèi)生標準的分析方法、GB/T 5009.56-2003 《糕點衛(wèi)生標準的分析方法》；過氧化值檢測儀可以廣泛應(yīng)用于產(chǎn)品質(zhì)量監(jiān)督檢驗、工商管理、油炸食品生產(chǎn)基地、市、商場、各大食品安全監(jiān)測系統(tǒng)等部門。 
食用油過氧化值是評價食用油是否符合衛(wèi)生標準常用的理化指標之一。過氧化值越高，說明油脂和脂肪酸被氧化程度越高，食用油的變質(zhì)就越嚴重，對人體的危害也越大。食用過氧化值標的食品可能會導(dǎo)致腹瀉，加速衰老，皮膚長斑等多種不良后果。 
過氧化值檢測儀由光源、比色池、高靈敏度集成光電池、微處理器、全漢字大屏幕液晶屏、嵌入式微型熱敏打印機、無線傳輸模塊和集成芯片構(gòu)成，可直接在大屏幕液晶屏上顯示出被測樣品中相關(guān)指標的含量，并打印出分析結(jié)果，還可以通過計算機接口將數(shù)據(jù)傳輸?shù)?ldquo;食品安全信息系統(tǒng)”終端數(shù)據(jù)庫進行分析。該方法單次檢測成本較低、操作簡便快速， 方便*人員或生產(chǎn)質(zhì)控人員現(xiàn)場使用和車載使用。 
儀器原理：被檢樣品中的相關(guān)指標成分與顯色劑在一定的條件下發(fā)生特異性反應(yīng)，可生成不同顏色深度的產(chǎn)物，這些產(chǎn)物對不同波長可見光會產(chǎn)生有選擇性吸收，顏色的深淺即吸光度的高低與樣品中該指標成分的濃度成相關(guān)性，并在適當?shù)臐舛确秶鷥?nèi)服從朗伯—比爾定律。因此檢測的吸光度值經(jīng)儀器內(nèi)置的標準曲線軟件自動計算可得出樣品中該指標成分的準確濃度及是否標的結(jié)果。
