Abstract

Application of microwaves and IR radiation in the thermal processing of honey was investigated, and their effects on the physicochemical properties and microbiological quality of the honey were studied. Microwave heating provided a rapid means of achieving the desired level of yeast reduction with reduced thermal damage. Though different combinations of heating duration and microwave power intensity achieved the commercially-acceptable level of yeast reduction in honey, heating for a shorter duration (15 s) at a higher power intensity (16 W/g) was desirable in terms of the lower hydroxymethylfurfural value (3.8 mg/kg) and higher diastase activity (12.0) obtained. IR heating was not as rapid as microwave heating, but achieved the desired results in a relatively short period (3-4 min) offering advantages over the conventional method.
