ABSTRACT

This article investigated the effect of altitude on milk of camel, goat and sheep with regard to their laser induced fluorescence spectra, pH, conductivity, moisture, Total Dissolved Solids (TDS), specific gravity and ash percentage. The altitude significantly affected the specific gravity and the ash percentage of all the studied milk’s samples while it with the altitude significantly affected the pH and conductivity of the camel and goat milk samples. The high altitude sheep and goat milk samples were characterised by the highest fluorescence intensity compared to their low altitude milk while the low altitude camel milk had the highest fluorescence intensity compared to the high altitude camel milk. The laser induced fluorescence (LIF) technique was very useful in differentiating between the altitude and animal source of the studied milk samples.

Key words: Altitude effect, ash, camel, conductivity, laser induced fluorescence, milk
