How long does red velvet cake dye take to digest?

The digestion time for red velvet cake dye, typically made from food coloring such as Red 40 or natural sources like beet juice, varies depending on individual metabolism and digestive health. Generally, food dyes are processed quickly by the body, often within a few hours, as they are not absorbed but rather pass through the digestive system. However, the overall digestion of the cake itself, including its ingredients, may take longer, usually around 24 to 72 hours.
