Wahyudi David, Kurnia Ramadhan

Abstract

The study is aiming to compare selected liquid smoke by product (coconuts shell, pangium shell, candlenuts shell, cocoa bean shell and palm kernel shell). The principal component analysis (PCA) was used to grouped and reduce the number of variables. The analysis using principal component analysis (PCA) performed by XLSTAT. It is showed that the principle component analysis able to distinguish the tendencies of chemical component obtained by different sources of liquid smoke materials. All liquid smoke samples are in different quadrants except forcocoa bean shell and palm kernel shell which are lie at the same quadrant.
