Abstract:
In the production bread wheat bran is used as a raw material rich in dietary
fiber. Therefore, it is necessary to monitor the content of essential and
toxic elements in the flour and bran. This paper investigates essential (Zn,
Cu, Fe and Mn) and toxic (Pb, Cd, Hg and As) elements in products of milling
wheat grown in the whole territory of Banat, the region in Serbia.
Inductively Coupled Plasma Mass Spectrometry was used for analysis. The mean
contents of the following elements Pb, Cd, Hg, As, Fe, Mn and Zn in wheat
kernels were 0.143 mg/kg, 0.007 mg/kg, 0.017 mg/kg, 35.7643 mg/kg, 50.865
mg/kg, and 21.174 mg/kg, respectively. Cluster Analysis (CA) and Principal
component analysis (PCA) was applied to discriminate and to group the
different samples, according to element content. Quality results show that
the first two principal components, accounting for 80.17% of the total
variance, can be considered sufficient for data representation and the first
two principal components of toxic elements and essential microelements. Cd
(15.28%), Zn (17.91%), Cu (17.08), Fe (16.91%) and Mn (17.54%), have been
found the most influential for the first factor coordinate calculation, while
the contribution of Pb (27.93%) and Hg (61.86%) has been the most important
variable for the second factor coordinate calculation.
