الملخص EN

Benzene is a human carcinogen, according to the international agency for research on cancer (IARC).

chronic exposure causes blood disorders, especially in bone marrow.

Benzene is formed in beverages and foods containing both benzoate salts and ascorbic acid, by decarboxylation of benzoate under certain conditions.

exposure to light and high temperature during shelf life is considered a factor that stimulates benzene formation.

in this study, benzene levels was determined in several beverages containing benzoate salts and ascorbic acid.

these samples were exposed to high temperatures for different times (40°C for 24 hours, 40°C for two weeks).

the samples were analyzed using a headspace gas chromatography-mass spectrometry method HS-GC-MS.

the benzene was detected in a number of samples containing benzoate and ascorbic acid, but the percentage did not exceed the authorized global values.

no benzene was detected in the benzoate free sample under all applicable conditions.
