Detection method of mycotoxin

This post was finally edited by biocn in 2009-4-3 15:23, such as aflatoxin detection: detection principle: aflatoxin test kit is based on competitive enzyme-linked immunosorbent assay (Elisa). Aflatoxins in crushed samples were extracted with methanol / water concussion, filtered aqueous phase extract, and then immunological detection was carried out. The enzyme marker of aflatoxin was added to the test hole with standard or sample, and the reaction began after the antibody was added, and the sample and the enzyme marker competed to bind the antibody attached to the micropore. After 10 minutes of culture, the solution in the pore was poured out. Wash out the unbound aflatoxins and enzyme markers in the micropores. A colorless substrate solution was added and cultured for 10 minutes, and all the bound enzyme markers converted the substrate into a blue substance. The aflatoxin concentration of the sample can be obtained by adding the stop solution and then reading the absorbance value, and comparing the unknown concentration sample with the standard absorbance value. -- people who swipe forum coins. True Halo-Feed mycotoxin testing Service Beijing Tyloqi testing Laboratory is a domestic food manufacturer, processing trader and raw material supplier relying on the proprietary technology and testing product advantages of the American Trilogy analytical laboratory. And suppliers of natural organic products, functional health products and conventional products provide mycotoxin testing, composition analysis and related technical consulting services. The testing services we provide include rapid testing and standard testing services. For more information, please visit the website: http://www.mycotoxinlab.cn ◆ mycotoxin analysis to detect mycotoxins are toxic mold metabolites, found in a variety of grains, feed, food and beverages, some compounds can cause serious human and animal health problems. Mycotoxins can invade food and feed during production, handling, transportation or storage. The Teloki testing laboratory can detect more than 20 mycotoxins such as aflatoxin, fumonisin, herlatoxin and vomiting toxins. Our mycotoxins analysis methods include: ■ high performance liquid chromatography ■ gas chromatography-mass spectrometry ■ thin layer chromatography TLC ■ enzyme linked immunosorbent assay the types of mycotoxins that can be detected by ■ aflatoxins: aflatoxins B1 aflatoxins aflatoxins B2 aflatoxins G1 aflatoxins G2 Total ■ A / B single-ended sporomycene compounds of aflatoxin B1, B2, G2: Tmur2 toxin, HT-2 toxin, serpentine toxin (Diacetoxyscirpenol) (nivalenol diacetate) Neosolaniol, DON vomiting toxin, 3-acetyldeoxynivalenol, (3 Acetyl DON) 5-acetyldeoxynivalenol, (15 Acetyl DON) nivalenol (Nivalenol) Fusarium ketene-X (Fusarenon-X) ■ fumonisins: fumonisin B1 (fumonisin B1), fumonisin B2 (fumonisin B2) ■ zearalenone (zearalenone), ochratoxin A (ochratoxin A) ■ citrinin (Citrinin) Patulin can provide mycotoxin testing services for the following products: ■ raw grains (such as grains, corn, soybeans, etc.) ■ feed and raw materials (such as soybean meal, corn, pet food) ■ food raw materials (including starch) Rice protein, corn protein, wheat gluten, grain and oil, flour, soybean products, etc.) ■ food processing products food, feed composition analysis: there are a variety of food feed additives, organic acids, sugars and alcohols are commonly used additives, their uses are also different. Tailuoqi laboratory can provide organic acids and sugar alcohols detection services for wine, fruit juice, food and feed industry. Tailuoqi testing Laboratory can provide testing services for organic acids and sugar alcohols for wine, fruit juice, food and feed industries. Quantitative analysis of ◆ organic acids: including malic acid, citric acid, acetic acid, lactic acid, pyruvate and so on. Quantitative analysis of ◆ sugars and alcohols: mainly lactose, D-galactose, glucose, fructose, sucrose, starch, ethanol, mannitol, glycerol and so on. ◆ analysis of other substances: ammonia, urea, ketone body, carnitine, dietary fiber, sulfite, sulfur dioxide, heavy metal iron and copper. Mold identification can detect, isolate and identify potentially dangerous molds and yeasts found in a variety of beverages, foods, feeds, grains and paper products. Early identification is also one of the means to prevent the production of mycotoxins and control from the root causes. Beijing Taileqi testing Technology Co., Ltd.
