| Abstract:
The effect of cultivar and osmotic dehydration technology in plum processing was investigated. Experiments were conducted on pitted fruits of 8 cultivars (Italian Prune, Lowicz Prune, Dabrowice Prune, Cacanska Lepotica, Cacanska Rodna, Empress, Bluefre and Amber). The cultivar influenced strongly product quality. From Bluefre and Empress significantly worse products were obtained. Osmotic dehydration as a pretreatment before convective drying improves taste of prune by increase of soluble solids to acidity ratio. Results obtained indicate that technology with osmo-convective dehydration is ideal for processing of low soluble solids plums grown in our climate. | |
