IPA: /ˌʌnhoʊməˈnaɪzd/
KK: /ʌnhoʊməˈdʒaɪzd/
Describing a substance that has not been made uniform in composition or consistency.
The milk was unhomogenized, so the cream rose to the top.
Unhomogenized → It is formed from "un-" (meaning not) and "homogenized" (from Greek "homogenes", meaning of the same kind). The word "unhomogenized" means not made uniform or not having the same composition throughout.
Think of 'not' ('un-') being applied to something that is 'of the same kind' ('homogenized') — that's why unhomogenized means it is not uniform.
