The article explains the difference in color between milk and butter, focusing on the scientific reasons behind their distinct hues. It describes how milk appears white due to the scattering of light by its components, while butter takes on a yellow tint from beta-carotene present in the fat of milk. The color variation in butter depends on the cattle's diet, with grass-fed cows producing deeper yellow butter and those on hay or grain-based diets creating paler versions. Goat butter tends to be whiter because goats convert beta-carotene into colorless vitamin A. Some butter producers use annatto, a natural coloring agent, to ensure a consistent golden appearance. The article notes that while a darker yellow suggests higher beta-carotene content, color alone does not determine health benefits.
