Experimental investigation of particle size distribution in commercial tahina

الملخص EN

Tahina samples were obtained locally.

Using a unique approach for particle size analysis, a microscope with electronic output was utilized, and the distributions of solid particles contained in tahina produced by various manufacturers were studied.

Available software was employed to measure areas and perimeters of particles.

Then average equivalent diameters and circularities were computed for samples of tahina from six manufacturers.

It was determined that there exist substantial differences in particle size distributions, average equivalent diameters and circularities of tahina produced by the different manufacturers.

Preliminary guidelines were proposed for the classification of tahina in the light of these findings.
