What is the sole stated purpose for adding artificial food colorings like those derived from petroleum?
Answer
Aesthetic appeal, making foods look brighter or more vibrant.
Artificial food colorings, often cited alongside other controversial additives, are unique in that they do not contribute nutritional value, preservation, or functional texture to the food matrix. Their addition is purely cosmetic. These dyes, frequently synthetic and derived from petroleum sources, are incorporated into products solely to enhance visual appeal. The goal is to make the food appear brighter, more intense, or more vibrant than its natural state might allow, thereby increasing consumer attraction on the shelf. Concerns often focus on behavioral links, particularly hyperactivity in children, arising from an ingredient added solely for looks.
