Study On The Influence Of Different Drying Modes Over The Chemical Composition Of Organic Fruits Of Some Plum Cultivars

The change of some biochemical indicators of fruits of some plum cultivars was followed under the influence of different equipments and drying modes. In the first variant for the process of drying was used an alternative energy source – solar energy, and in the second one – a heat pump.The highest dry matter content was found in the fresh fruits of Mirabelle de Nancy – 25.50 %. In the alternative source of drying of fruits, Gabrovska cultivar had the highest content of biological active substances (ascorbic acid – 8.80 mg%) and Stanley (anthocyanins – 40.81 mg %). In the heat pump drying of fruits, Stanley had the highest content of both components
