Determınatıon of Physıcal and Chemıcal Propertıes of Marmelats Produced From Hunnap (Zizyphus Jujuba Mill.) Fruıt

In this study, the changes in the physical and chemical properties of jujube (Zizyphus jujuba Mill.) Fruit and marmalade produced from this fruit at different temperatures (+4 C and +20 C) during storage for 3 months were determined. Water soluble dry matter, titratable acidity, pH, dry matter, ash, ascorbic acid (vitamin C), sucrose, invert sugar, total sugar, color in the 0, 1, 2 and 3 months of three months storage, Total phenolic substance, antioxidant capacity (ABTS and DPPH), yeast and mold analyzes were performed. During the storage period, in marmalade samples produced from jujube fruit, a decrease was observed in the amount of water soluble dry matter, invert sugar, total sugar, ash, dry matter, ascorbic acid (vitamin C), L, a, b values, phenolic substance and antioxidant activity amounts. In terms of temperature, high values are found in water soluble dry matter, pH, total sugar, invert sugar, ABTS and DPPH among the parameters examined from storage at + 20ºC, while in storage at + 4ºC; The highest values were obtained in terms of total dry matter, ascorbic acid, sucrose, L, a and total phenolic substance.
