Abstract:

Taking styrene migration amount as a test indicator, the migration of residual styrene in polystyrene cups to three types of food and alcohol simulants was investigated comparatively, and the suitable food simulants from the Chinese special food series were confirmed. The migration amount of styrene from the polystyrene cup to bean beverages, tofu, porridge, and 10 and 20 vol% alcohol was detected using headspace?gas chromatography. Meanwhile, the migration amount of styrene from the cup to 50 and 95 vol% alcohol was determined by high?performance liquid chromatograph. The results indicated that the migration amount of styrene in the bean beverages was between the migration amounts in 20 and 50 vol% alcohol. The migration amounts of styrene in tofu and porridge was closed to the migration amounts in 10 and 20 vol% alcohol, which were much lower than that in 50 vol% alcohol. According to the migration results, 50 vol% alcohol was recommended as a simulant for bean beverages, and 20 vol% alcohol as a simulant for tofu and porridge. These results provided a data reference for reformulating the national food safety standards.

Key words: bean product, porridge, styrene, food simulant, applicability
