Screening for the Presence of Patulin in Molded Fresh

Screening for the Presence of Patulin in Molded Fresh

A screening for the presence of patulin in molded fresh produce was conducted. Patulin was present in 11 of the sweet bell peppers and in 8 of the soft red fruits, but not in onions. Patulin was also found in tomatoes, but could not be detected in derived tomato products. When the production process of tomato concentrates was simulated, none of the evaluated hypotheses could however explain ...
