Processed commodities (hydrolysis study) | Conditions | Stable? | Comment/Source |
---|---|---|---|
Pasteurisation (20 min, 90°C, pH 4) | Yes | Finland (2021) | |
Baking, brewing and boiling (60 min, 100°C, pH 5) | Yes | ||
Sterilisation (20 min, 120°C, pH 6) | No (quizalofop‐P‐ethyl was partly hydrolysed to quizalofop) | ||
A standard hydrolysis study performed with quizalofop‐P‐terfuryl was assessed in the framework of the MRL review demonstrating that quizalofop is not expected to degrade hydrolytically under conditions representative of three different processing practices (EFSA, 2017). A new study performed with quizalofop‐P‐ethyl was also submitted with this application. As quizalofop‐P‐ethyl and quizalofop were the main compounds detected in the buffer solutions in conditions simulating pasteurisation, baking/brewing/boiling and sterilisation, it can be concluded that the residue definitions for primary crops are also applicable to processed commodities |
