French walnut oil stopped at border over banned additiveStaff writer, with CNAA 30kg shipment of walnut oil imported from France was recently blocked at the border after tests found it contained the color additive copper chlorophyllin A, which is banned in edible oils. The walnut oil was imported by a Taiwanese company that advertised its products as natural, non-toxic and environmentally friendly, the Food and Drug Administration (FDA) said today. However, testing showed that the oil contained 0.1 parts per million of copper chlorophyllin A, which is not permitted in edible oil products under the Standards for Specification, Scope, Application and Limitation of Food Additives (食品添加物使用範圍及限量暨規格標準), the agency said. French walnut oil is pictured in an undated photograph. The importer is to face stricter inspections of its shipments, while walnut oil products from France are also to face heightened scrutiny at the border.
