The objective of the study was to determine the impact of temperature and time of storing candied fruit on the content of sorbic acid and reducing sugars, and on changes in the total acidity of the fruit studied. The material analysed consisted of candied fruit (gooseberry, plum, rowanberry) produced by “Prospona” Ltd. Co., in its Food and Vegetable Processing Plant. Candied fruit has been stored for eleven months at a refrigerating temperature (8 ºC) and a room temperature (20 ºC). The analyses were performed after 3, 5, 7, 9 and 11 months of storage. Based on the results obtained, it was found that the temperature and time of storage impacted the content of sorbic acid. Throughout the entire storage period, all the fruit stored at a refrigerating temperature were characterized by a higher level of sorbic acid compared to the fruit stored at a room temperature. Besides, after eleven months of storage, and irrespective of the storing temperature, a slight decrease in total acidity and an insignificant increase in the content of reducing sugars were found in the products studied. Only in the candied gooseberries, stored at a room temperature, the content of reducing sugars was higher than in candied gooseberries stored at a refrigerating temperature 8 ºC.
