摘要：In this research, Golden delicious apples were classified taking note of the rotten proportion on the space as sound and 30%, 60% and 100% decayed. Classified apples are used in the production of apple juice. Then patulin, fumaric acid, HMF, pH, brix and Hunter L, a, and b values of apple juice samples were determined. It was determined that amount of patulin of the clear apple juice produced with Golden delicious apples that have 30%, 60% and 100% decay proportion were ranged between 36,2-508,50 j/g/kg, 96,1-1153,2 j/g/kg, 66,7-564,7 j/g/kg, respectively. The amount of fumaric acid of clear apple juice produced with Golden delicious apples that are sound and have 30%, 60% and 100% decay proportion were found between 0,00-0,25 mg/kg, 0,30-0,64 mg/kg, 0,61-1,95 mg/kg, 0,93-3,16 mg/kg, respectively.
