Describing something that has not gone through the process of fermentation, meaning it has not been changed by the action of yeast or bacteria.

Unfermented → It is formed from "un-" (meaning not) and "fermentare" (meaning to ferment). The word describes something that has not undergone the process of fermentation.
Think of 'not' ('un-') having gone through the process of 'fermentation' ('fermentare') — that's why unfermented means something that hasn't fermented.
