Questions about tocopherol-rich extract
Is tocopherol-rich extract (vitamin E) harmful?
In 2015 EFSA re-evaluated tocopherol-rich extract (E306) and alpha-, gamma- and delta-tocopherol (E307–E309) and concluded that the available data were too limited to establish an ADI for the tocopherols. EFSA said the dataset on tocopherol-rich extract, gamma- and delta-tocopherol was too limited to be included in the safety assessment. EFSA concluded that tocopherols (E306–E309) are not of safety concern at the levels used in food.
Is INS 306 permitted in Vietnam?
