In the United States, natural flavors are regulated by the FDA under the Food Additives Amendment of 1958. They must meet the same safety standards as artificial flavors. The European Union also has strict regulations, requiring flavors to be evaluated and approved by the European Food Safety Authority (EFSA). Despite these regulations, the specific components of natural flavors are often considered proprietary, which means manufacturers are not required to disclose the full list of ingredients to consumers, sometimes leading to concerns about transparency.
