[Determination of microminerals in wheat flour using the method of HCl extraction and FAAS].
The content of microminerals in wheat flour, including Cu, Zn, Fe, Mn, Ca and Mg, was determined using the method of HCl extraction and FAAS. Meanwhile, the temperature, time and pH of extracting were also selected. The results indicated that the extracting effect of the microminerals was as same as the effect of wet ashed method except that Mg could not be extracted completely. This method is an ideal pretreatment of samples due to its simple, rapid, accurate characteristics.
