Analytical methods were developed to estimate the nitrosatable morpholine and apparent N‐nitrosomorpholine content of paper and paperboard direct contact food packaging. Examination of 34 different paper or paperboard food packages indicated 9 to be contaminated with detectable levels of apparent N‐nitrosomorpholine. All 12 packages analyzed for nitrosatable morpholine were positive with an average level of 380 μg/kg. Migration of apparent N‐nitrosomorpholine and morpholine to food was demonstrated when paper or paperboard and dry food were incubated in a closed container for 3 days at 100°C.
