There were many studies using chemometric analysis to classify samples according to their geographical origin. This preliminary study was carried out to determine if selected composition in EBN can be used to classify samples according to their geographical origin. In this study, concentrations of protein, sialic acid, nitrite, nitrate and minerals (23 elements: Pb, Cd, As, Hg, Sn, Sb, Na, Ca, K., P, Fe, Al, Mg, Mn, Cr, Co. Ni, Cu, Zn, Se, Sr, Ba and V) were determined in 47 samples of EBN from Johor, Penang and Terengganu. The evaluation of EBN sample composition using PCA showed that it is possible to identify grouping of samples according to their origin. More samples from different states and countries are needed to have more conclusive result if this approach is to be used to group EBNs according to each states in Malaysia and other countries.
