Processed commodities (hydrolysis study) Conditions Investigated?
Pasteurisation (20 min, 90°C, pH 4) Yes
Baking, brewing and boiling (60 min, 100°C, pH 5) Yes
Sterilisation (20 min, 120°C, pH 6) Yes

Active radiolabelled substance: U‐phenyl ‐14C‐folpet

Comments: Folpet completely degraded predominantly to phthalimide, (pasteurisation: 92% AR; baking, brewing/boiling: 58% AR) with levels of phthalic acid increasing with temperature and pH (baking, brewing/boiling: 42.2% AR; sterilisation 81% AR)
