Which term describes an oily yellowish appearance in milk?

An oily yellowish appearance in milk comes from fat separating and rising to the surface, creating a thin, oily, yellow layer. This is the description of creaming, which happens when the fat emulsion isn’t fully stabilized—often due to inadequate homogenization or aging/storage conditions. It’s a surface appearance defect, different from gummy (sticky texture), sandiness (gritty crystals), or coagulated (curdled solids). So the best descriptor for that oily, yellowish look is the fat separation at the surface, i.e., creaming.
