Abstract:

This study aims to investigate the formation of heat-induced contaminants such as furan, furfural, 5-hydroxymethylfurfural (HMF) and acrylamide in roasted chickpea samples using different roasting methods (microwave, microwave-hot air combination, hot air). In addition to heat-induced contaminants of roasted chickpea samples, browning index (BI), ultraviolet absorbance (UV-A) and Hunter L, a and b color values were also determined. While different roasting methods had a statistically significant (p<0.01) effect on BI, UV-A and color values of roasted chickpea samples, BI, UV-A and Hunter a values increased with increasing roasting temperature and time. In the study, the highest heat-induced contaminant formation was determined in the hot air roasting method, while the microwave roasting method gave the lowest results in all heat-induced contaminants. It was determined that the acrylamide content of the samples did not increase with the roasting process and remained below the limit of quantification (LOQ) value in all samples.
