New measures adopted by the European Commission designed to streamline the approval of additives, colors, flavorings and enzymes, could result in longer approval procedures for US exporters, with some presently approved ingredients potentially restricted in the future, according to a US lawyer. Under the new proposed rules, harmonized Community rules would be laid down for the evaluation, approval and control of enzymes used in food. At the same time, the EU Executive proposes to review the current rules on food additives and flavorings and to introduce a simplified common Community approval procedure for food additives, flavorings and enzymes.
