Pigments: The Color-Creating Molecules

The color of sweet potatoes is primarily determined by the presence of pigments, which are natural compounds that absorb specific wavelengths of light and reflect others. In the case of yellow sweet potatoes, the dominant pigment is beta-carotene, a carotenoid that also gives carrots their characteristic orange color.

Genetics: The Blueprint for Color

The genetic makeup of a sweet potato variety plays a crucial role in determining its color. Different varieties of sweet potatoes contain varying amounts of different pigments, which can result in a range of colors from pale yellow to deep orange.

Environmental Factors: Nature’s Influence

Environmental factors can also influence the color of sweet potatoes. Factors such as sunlight exposure, temperature, and soil conditions can impact the production and accumulation of pigments in the sweet potato.
