Is full fat milk a homogeneous?

Full-fat milk is considered a colloid, which is a type of heterogeneous mixture rather than a homogeneous one. While it appears uniform and consistent when mixed, the fat globules can separate over time, leading to a non-uniform distribution of fat. To maintain its consistency, full-fat milk often undergoes homogenization, a process that breaks down fat molecules to prevent separation. However, even with homogenization, it can still exhibit slight variations if left to sit.
