    The aim of this work is to compare the applicability of particle diameter prediction mathematical models (i.e. Tate s Law equation, the modified Tate s Law equation, the modified Yildirim s model) to determine diameter of liquid core capsules. The capsules were produced by extruding xanthan gum-calcium chloride solution through a hypodermic needle into sodium alginate solution. The effects of two types of xanthan gum with different concentrations and needle diameters on capsule diameter were investigated in this work. The results showed that there was no significant difference in capsule diameter despite different types and concentrations of xanthan gum were used. However, the diameter of the capsules increased when the diameter of needles increased. As a whole, the produced capsules were in the range of 3.47 mm to 4.86 mm. Among the three studied prediction models, the modified Tate s Law mathematical equation was the most suitable model for the diameter prediction of the liquid core capsules with AAD of 2.74 and MAD of 6.55 .
