Abstrakty
W artykule przedstawiono ocenę wpływu parametrów procesu suszenia mikrofalowo-konwekcyjnego na barwę truskawek. Suszenie mikrofalowo- konwekcyjne (poziom mocy: 50, 75 i 90 W, temperatura powietrza 30 i 40ºC) zostało przeprowadzone w 6 kombinacjach eksperymentów. Oceny barwy truskawek dokonano metodą kolorymetryczną w systemie Hunter Lab oraz z zastosowaniem komputerowej analizy obrazu. Stwierdzono, że im wyższa temperatura i moc mikrofal, tym czas suszenia był krótszy. Wyniki względnych pomiarów parametrów barwy dla obu metod charakteryzują się wysokimi współczynnikami korelacji.
In this work evaluation of microwave - convective drying parameters influence on strawberries color was presented. Microwave- convective drying (power levels of 50, 75 and 90 W as well air temperature of 30 and 40°C) were applied for drying processes which were performed within 6 combinations of experiments. Color of strawberries was measured using colorimetric measurement – Hunter Lab and computer vision method. It was affirmed that with higher temperature and with higher microwave power the time of drying was shorter. Results of relative measurements of color parameters for both methods were characterized by high correlation coefficients.
