Fig 4. Sola l 4 content in dried and fresh tomatoes.

(A) Allergen content in μg Sola l 4/g fresh weight (FW) of tomato cultivars SAAB and (B) Perbruzzo determined with indirect competitive ELISA. Plants were grown in Italy in 2015 and 2016 conventionally with artificial mulch (conv), organically with artificial mulch (org) and organically with natural mulch (norg). Tomato fruits were dried via freeze-drying (freeze), in the oven (oven) and in the sun (solar). Allergen content of dried tomato samples was referred to μg Sola l 4/g FW and compared with fresh tomatoes (fresh). Significant differences for each group were calculated at a significance level of 5%.
