*, concentrations exceeding the MLs of the current GSFA.
Source of analytical data: Soubra et al. (2007). National legislation: not available.
Note: It is not possible to know which are the current practices of the Lebanese food industry with regard to food additive usage in the absence of
national regulation. Sulfite residues were analysed in products as consumed (after cooking if necessary). Each sample was prepared from five individual
brands, weighed to represent the market share. Sulfites were detected in 68 (72%) of 94 analysed foods. The determination of sulfites and sulfur dioxide
was performed according to the enzymatic method.
