28 Conclusions
29 Conclusions The optimum extraction yield by microwave extraction was g GAE/g dry peel at 600 W, 50% EtOH as solvent, liquid/solid ratio of 60/1 ml/g and extraction time of 4 min. The optimum extraction yield by ultrasound extraction was g GAE/g dry peel at 34.7 ο C, water as solvent, liquid/solid ratio of 32.2/1 ml/g, amplitude level up to 39.8%, pulse duration/pulse interval ratio of 7/6 and extraction time of 10 min. The optimum moisture content in order to maximize the extraction yield was 45% w.b. for the microwave extraction and 14% w.b. for the ultrasound extraction. The enzymatic pre-treatment using cellulase and pectinase did not enhance the extraction.
30 Conclusions The drying rate increased on increasing the temperature, whereas the drying occurred mostly in the falling rate period. The effective diffusivity values varied between and m 2 /s and the activation energy was found to be kj/mol. Phenolics content of pomegranate peel decreased by 60-75% after drying at o C and higher temperatures caused more loss of phenolic substance. The degradation of phenolics during drying can be described by a 1 st order kinetic model.
