食品檢測實驗室規(guī)劃
食品檢驗可分為兩大項,一是檢測產(chǎn)品的品質(zhì)項目:二是檢測產(chǎn)品的衛(wèi)生項目,這一類項目的檢測相對難度大、投資高。衛(wèi)生項目包括微生物、添加劑、有害元素、農(nóng)殘留、獸殘留、毒素等。
微生物:
建微生物實驗宰要按照生物實驗宰設(shè)備及裝備規(guī)范標(biāo)準(zhǔn)要求進行布局。必要的設(shè)備有潔凈臺、培養(yǎng)箱、高 壓滅菊鍋、電爐等,其它設(shè)備則根據(jù)具體檢瀾項目配置。
添加劑和有害元素:
有一部分項目可以用化學(xué)法、但想滿足現(xiàn)在國標(biāo)的食品衛(wèi)生要求,應(yīng)該購置氣相色譜-氫火焰檢測器、液相色譜-紫外/可見光檢測器、原子吸收儀-石墨爐檢測器、原子熒光儀等。
殘留農(nóng)藥:
檢測殘留農(nóng)藥氣相色譜是不能少的。檢測有機氯農(nóng)藥,需配電子俘獲ECD檢測器;檢測有機磷農(nóng)藥,需配火焰光度FPD檢測器或氮磷檢NPD檢測器?,F(xiàn)在農(nóng)殘檢測的項目越來越多,為提高通用性,建議配置毛細管柱分流/不分流進樣口,安裝毛細管色譜柱。出口食品加工企業(yè)未來把好生產(chǎn)原料和產(chǎn)品質(zhì)量關(guān),可以配置氣相色譜-質(zhì)譜儀。殘留獸藥:
若進行殘留獸藥的檢測,項目不多且批次多,可以配置酶聯(lián)免疫儀。對于有一定規(guī)模的出口食品企業(yè), 最好配置一臺液相色譜-串聯(lián)質(zhì)譜儀。
Food Inspection Planning, food inspection can be divided into two major items, one is to test the quality of products, the other is to test the hygiene of products, this type of project testing is relatively difficult and high investment. Health items include microorganisms, additives, harmful elements, agricultural residues, animal residues, toxins and so on. Microbiology: The layout of the biological laboratory slaughter equipment shall be in accordance with the requirements of the biological laboratory slaughter equipment and equipment specifications and standards. Necessary equipment has the clean table, the incubator, the high-pressure Pyrethrum Pot, the electric stove and so on, other equipment then according to the concrete check the LAN item disposition. Additives and hazardous elements: some items can be chemical, but to meet the requirements of the current food safety, you should purchase gas chromatography-hydrogen Flame detector, Liquid chromatography-ultraviolet / visible light detector, atomic absorption spectrometer-graphite Furnace Detector, Atomic Fluorescence Spectrometer, etc. . PESTICIDE RESIDUES: the detection of pesticide residues gas chromatography is not less. In order to detect organochlorine pesticides, ECD detector and flame photometric FPD detector or NPD detector are needed. In order to improve the generality, it is suggested that the capillary column should be equipped with Shunt / non-shunt inlet and the capillary column should be installed. Export food processing enterprises in the future to good production of raw materials and product quality, can be equipped with gas chromatography-mass spectrometer. Residual Veterinary Drugs: If the detection of residual veterinary drugs, items and batches, can be equipped with enzyme-linked immunosorbent assay. For a certain scale of export food enterprises, it is best to configure a liquid chromatography-tandem mass spectrometer.
