GB 5009.185-2016: Translated English of Chinese Standard. GB5009.185-2016: National Food Safety Standard - Determination of Patulin in FoodsThis Standard specifies methods for the determination of patulin in foods. Method 1 of this Standard is isotope dilution - liquid chromatography tandem mass spectrometry, which applies the determination of patulin content in fruits and products of apple and hawthorn, fruit and vegetable juices and alcoholic foods. Method 2 of this Standard is high performance liquid chromatography, which applies the determination of patulin content in products of apple, its fruit and vegetable juices and alcoholic foods. |
