摘要
Colour change during infrared heating of wheat germ was studied at 100-150degreesC for 5-40 min. An increase in L values and a decrease in a values were observed at increased time and temperature of heating. Scattered data were obtained for the b values. Results showed that the L and a values can be successfully modelled using a third-degree polynomial equation., which can be used to estimate the colour changes during heating. The activation energy for the colour changes in wheat germ, based on the L values. was found as 36.6 kJ/mol. (C) 2001 Elsevier Science Ltd. All rights reserved.
