An investigation on the relationship between patulin and fumaric acid in apple juice concentrates.

Seventy commercial apple juice concentrates were analysed to determine the correlation between patulin and fumaric acid content. No significant correlation was found for the samples having patulin lower than 50mg/L. The samples containing patulin levels ranging from 67 to 216 mg/L had a slightly higher correlation coefficient of 0.55. The most significant correlation coefficient of 0.71 was deter mined when all 70 samples were taken into account. During processing into apple juice concentrate, both patulin and fumaric acid content decreased through all the processing steps except evaporation. An appreciable amount of fumaric acid formed during evaporation while no significant change was observed in patulin.
