the word is a modern scientific formation, directly constructed from existing english morphological elements. the core root 'pasteur' is an eponym, borrowed from the surname of the 19th-century french chemist and microbiologist louis pasteur. the suffix '-ized' is attached to indicate the application of the pasteurization process. finally, the germanic negative prefix 'un-' is added to form an adjective describing something that has not undergone that specific treatment. thus, the term's logic is transparently built: "not + pasteur + treated."

Structure: un (not) + pasteur (pasteur) + ized (made, treated) - un: a prefix of germanic origin (old english) meaning "not", indicating negation or reversal. - pasteur: a bound root derived from the surname of louis pasteur, the french scientist who developed the process. it functions as the core referent. - ized: a suffix of greek origin (via latin -izare and french -iser) meaning "made into, treated by, or subjected to a process". it forms adjectives from nouns.
