Written for presentation at the 2007 ASABE Annual International Meeting Sponsored by ASABE Minneapolis Convention Center Minneapolis, Minnesota 17 - 20 June 2007 Abstract. In order to discourage the use of chemicals in raisin processing, the effect of Microwave and Pulsed Electric Field (PEF) pretreatments on the drying rate and other quality parameters like color, total soluble solids, bulk density, appearance and market quality were compared with that of chemically pretreated raisins dried at 65°C. The untreated and pretreated samples had a statistically significant difference in drying rate (P
