and potential for creating of new products by infusion of specic additives into the berry structure through osmotic action (. Dry strawberry and raspberry puree, granules, and powders are usually processed in drum and spray dryers (. High-temperature short-period spray drying of fruit pasteis carried out after mixing with some carrier products such as maltodextrin, starch, or cornsyrup solids. The added carrier materials prevent clumping of the product during dryingand storage. Foam mat drying is also potential method. 4.1.5 Tropical and Subtropical Fruits Dry tropical and subtropical fruit products are becoming more popular as it is more conve- nient to handle them in the dry form than as fresh products. Further, they are more microbi- ologically safe because some thermal inactivation of microorganisms occurs during drying(8,. wide variety of fruits are dried as whole fruit or as slices, chunks, granules,or powder. Some of these are described in the sections that follow. 4.1.5.1 Fig Depending on the cultivar, dry gs are processed in slightly different ways, both by natural sun and by articial means. The difference is sulfuring pretreatment, which is practicalfor some cultivars, such as Adriatic and Kadota, but never used for Calimyrna andMission. The process starts with defuzzing (removal of surface hair) in 0.2% solution of salt and hydrated lime. This is followed by sulfuring and sun drying, or alternatively drying is carried out directly in the sun without sulfur treatment. For better skin appear-ance, drying in shadows and stacks is the most typical procedure. For articial drying,the hair-free gs are halved, sometimes sulfured, and dried on trays in countercurrenttunnel dryer. The nal moisture of 5% (..) is obtained after 8 of drying with hot 6 Grabowski et al. air at temperature about 7 . In some operations, the is dried to less than 3.5% and cut into slices of about 1 /H1 mm or powdered. More details of drying are presented by Desai and Kotec
