CHANGES IN ELECTRIC PROPERTIES OF APPLE JUICE CONCENTRATE AS A FUNCTION OF SELECTED QUALITY FACTORS

The research presented aimed at determining the electric properties of apple juice concentrate obtained industrially as well as at identifying the effect of selected quality factors on changes in its electric properties. A highly significant positive correlation was found between impedance and resistance values and extract content, refractive index value and density of the apple juice concentrate. On the other hand, a highly significant but negative correlation occurred between admittance and conductance and the parameters mentioned. No significant mathematical correlations were reported between reactive and potential acidity of the apple juice concentrate, its viscosity and electric properties measured.

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.
