What is the effect of acid on carotenoids?

• A. Enhances the orange color
• B. Turns them yellow
• C. They remain unchanged
• D. Decreases brightness

Answer: (C)

Carotenoids are pigments found in various fruits and vegetables, contributing to their vibrant colors, particularly in tomatoes, carrots, and peppers. The effect of acid on carotenoids is that it generally does not cause them to change in structure significantly; rather, they tend to remain stable. Carotenoids are relatively resistant to changes when exposed to acidic conditions because they are not highly reactive to varying pH levels. Their stability helps maintain the overall quality and color of the produce, which is important in food preparation and preservation. Acidic conditions can impact other components in food, such as proteins and certain vitamins, but carotenoids retain their color and structure even when exposed to acidic environments. This stability is essential for the culinary applications of these pigments, as they continue to provide color and nutritional benefits.
