Original Abstract

Příspěvek vychází z měření změny tvrdosti (pevnosti) tavených sýrů v závislosti na poměrovém zastoupení čtyř různých fosforečnanů v binární směsi a na době skladování tohoto sýra.

English abstract

The aim of this work was to study dependence of hardness of processed cheese spreads on the composition of binary mixtures of phosphate emulsifying salts which consisted of disodium hydrogenphosphate, tetrasodium diphosphate, pentasodium triphosphate, and/or sodium salt of polyphosphate and on number of days of storage. The main goal was to find suitable statistical models in order to describe the dependence of hardness examined on the composition of binary mixtures. Polynomial regression proved to be suitable for the global behaviour of the statistical relationship observed. Detailed observation of local changes was made by means of fuzzy inference system. In binary mixtures of polyphosphate combined with monophosphate, diphosphate or triphosphate, hardness was gradually increasing with rising amount of polyphosphate in mixture. In binary mixtures of monophosphate combined with diphosphate or triphosphate, a rapid increase in hardness of the samples was determined when the proportion of diphosphate or triphosphate in the mixture was rising up to 50–60 %.
