Abstract:
Objective:To observe the migration of 4,4＇-diaminostilbene-2,2＇-disulfonc acid-based fluorescent whitening agents ( DSD-FWAs ) in food packaging paper, so as to provide evidence for quality and safety supervision for paper packaging materials.
Methods:Forty-one paper samples with DSD-FWAs positive were made into 6 cm2 pieces and were soaked in four food simulants ( distilled water, 3% acetic acid, 10% ethanol and 95% ethanol, 10 mL each ). The experiment was carried out at the specified soaking temperature and time. The migration amounts of eleven DSD-FWAs were detected by high performance liquid chromatography-fluorescence detection.
Results:C.I.220, C.I.24, C.I.210, C.I.85, C.I.113, C.I.264, C.I.353 and C.I.357 were found in all the four food simulants. At the same time and temperature, the migration amount was highest in 10% ethanol, followed by distilled water, 3% acetic acid and 95% ethanol. C.I.220 was dissolved in all four food simulants, in the range of 20-90 ℃, the migration amount increased with soaking temperature; at 20 ℃, 40 ℃ and 60 ℃, the migration amount increased first and then stabilized over time.
Conclusion:The higher the storage temperature and the longer the storage time of paper packaging, the easier the DSD-FWAs in packaging paper migrate to food.
