Effects of dried fig fruits quality parameters and location on fumonisin B1 and B2 occurrence

Fusarium is the agent causing endosepsis (internal rot) in fig fruits and it is widespread in fig orchards in the Aegean region. It is an increasingly prevalent epidemic disease and it causes serious economic damage and loss of quality in dried fig production. This research was conducted to determine the natural occurrence of fumonisin B1 (FB1) and B2 (FB2) on dried fig fruits of 'Sarılop' (syn. 'Calimyrna') cultivar which are mainly grown in the Büyük and Küçük Menderes Valleys in the Aegean region, representing 60% of world dried fig production. A total of 262 samples belonging to two quality classes, Class A and Class cull, were collected from 12 different locations during the two consecutive crop years. FB1 was detected 70.8% of the 144 samples belong to Class A at the levels ranging from LOD to 0.334 µg g-1 and FB2 in 23.6% from LOD to 0.092 In the samples of Class cull, FB1 was found in 61.0% of 118 samples ranging from LOD to 0.185 µg g-1 and 18.6% FB2 from LOD to 0.198 µg g-1. Results of this study showed that there was negative correlation between occurrance of FB1, FB1+FB2 and crack fruit ratio and fruit color, positive correlation dried fruit firmness. There was significant differences between samples of locations in the terms of titratable acidity and fruit color, firmness and size.
