SN/T 2360的本部分規(guī)定了進(jìn)出口食品添加劑(營(yíng)養(yǎng)強(qiáng)化劑)的技術(shù)要求、抽樣、檢驗(yàn)、結(jié)果評(píng)價(jià)、綜合評(píng)定和處置及復(fù)驗(yàn)的原則。本部分適用于進(jìn)出口食品添加劑(營(yíng)養(yǎng)強(qiáng)化劑)的監(jiān)督檢驗(yàn)。
This European Standard specifies a method for the determination of vitamin B1 in food by high performance liquid chromatography (HPLC) with enzymatic treatment and pre- or post-column derivatization. This method has been validated in two interlaboratory studies. The first study was for the analysis of samples of whole meal flour, milk powder/spray dried milk, freeze dried mixed vegetables and freeze dried pig's liver ranging from 0,295 mg/100 g to 0,807 mg/100 g. The second study was for the analysis of samples of tube feeding solution, baby food with vegetables, powdered milk, meal with fruits, yeast, cereal, chocolate powder and food supplement ranging from 0,11 mg/100 g to 486 mg/100 g. Vitamin B1 is the mass fraction of total thiamin including its phosphorylated derivatives.
This European Standard specifies a method for the determination of vitamin B2 in food by high performance liquid chromatography (HPLC) and fluorescence detection. This method has been validated in two interlaboratory studies. The first study was for the analysis of samples of milk powder and pig's liver ranging from 1,45 mg/100 g to 10,68 mg/100 g. The second study was for the analysis of samples of tube feeding solution, baby food, powdered milk, meal with fruits, yeast, cereal and chocolate powder ranging from 0,21 mg/100 g to 87,1 mg/100 g. Vitamin B2 is the mass fraction of total riboflavin including its phosphorylated derivatives.
