چکیده انگلیسی
VitaFast® test kits designed for the microbiological assay in microtiter plate format can be applied to quantitative determination of B-group water-soluble vitamins such as vitamin B12, folic acid and biotin, et al. Compared to traditional microbiological methods, VitaFast® kits significantly reduce sample processing time and provide greater reliability, higher productivity and better accuracy. Recently, simultaneous determination of vitamin B12, folic acid and biotin in one sample is urgently required when evaluating the quality of infant formulae in our practical work. However, the present sample preparation protocols which are developed for individual test systems, are incompatible with simultaneous determination of several analytes. To solve this problem, a novel “three-in-one” sample preparation method is herein developed for simultaneous determination of B-group water-soluble vitamins using VitaFast® kits. The performance of this novel “three-in-one” sample preparation method was systematically evaluated through comparing with individual sample preparation protocols. The experimental results of the assays which employed “three-in-one” sample preparation method were in good agreement with those obtained from conventional VitaFast® extraction methods, indicating that the proposed “three-in-one” sample preparation method is applicable to the present three VitaFast® vitamin test systems, thus offering a promising alternative for the three independent sample preparation methods. The proposed new sample preparation method will significantly improve the efficiency of infant formulae inspection.
