9. Ultrasound Processing For Liquefying Crystallized Honey Crystallization of honey is a complex process controlled by a number of factors acting simultaneously and sometimes in a contradictory fashion Thrasyvoulou et al. S tudied the effects of ultrasonic waves on the quality of honey focusing on some of the chemical characteristics. Crystallized honey samples (100 g each) were liquefied by ultrasonic waves at 23 kHz and compared with conventionally heated (water bath heating; 60°C for 30 minutes) and untreated samples. The complete liquefaction of honey (5 samples each of blossom honey and honeydew honey) required 18 to 25 minutes of ultrasound processing. Accordingly the energy required for liquefaction varied from 0.1056–0.1466 kWh, and the maximum temperature attained by the samples from 76–82°C. Liquefaction by ultrasonic treatment affect the honey quality to a lesser extent compared to heat treatment

10. Membrane Processing Of Honey Anticipated benefits of membrane processing of honey are no cloudiness or sedimentation/granulation in the product, reduced viscosity, commercially sterile product and consistent quality characteristics. Ultrafiltrasi Mikrofiltrasi

11. Conclucion Microwave heating can be effectively used for thermal processing of honey , as it provides a rapid heating to achieve the desired results for long-term storage Ultrasound processing destroys most of the yeast cells present in the honey, besides eliminating the existing crystals and retarding further crystallization in honey Infrared heating is not as rapid as microwave heating but the desired results are obtained in a relatively shorter period of 3 to 4 minutes offering advantages over the conventional method.
