THE EFFECT OF HIGH-PRESSURE HOMOGENIZATION ON CHANGES IN MILK COLLOIDAL AND EMULSIFYING SYSTEMS.

The paper estimates the effect of high-pressure homogenization (20-140 MPa) on selected whole milk properties. High-pressure homogenization did not have a clear effect on the milk acidity. However, a slight increase in viscosity and a clear decrease in milk heat stability were observed along with an increase in the applied pressure. On the basis of a microscopic analysis and the measurement of the absorbance of milk samples, an increase in the fat dispersion degree was observed along with an increase in homogenization pressure up to 100 MPa. Homogenization, especially at the pressure over 80 MPa, resulted in an increase in susceptibility of milk globules to coalescence.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN. The program aims at improving the level of publishing and editing practices, increasing the impact of scientific journals on science development, and extending the international range of scientific journals.
