Experimental and analytical determination of freezing point depression

The work presents characteristics of determination and prediction of the freezing point of agricultural products and food with some analytical methods. Using 11 models and special software this property was computed including 299 freezing cases of differentiated products. To obtain that the authors experiments (52 products) were made. The data concerning other cases were drawn from literature. Model accuracy was estimated on the basis of results from the statistical analysis of relative error of prediction. The Chang-Tao’s method was regarded the best owing to its universality, while Salvadori-Mascheroni’s one the least accurate.
