'low-aleuronic' originates from Modern English, specifically a compound of 'low' (from Old English 'hlāw', where 'hlāw' originally meant 'mound' and later the sense 'not high') and 'aleuronic' (derived from 'aleurone', ultimately from Greek 'aleuron', where 'aleuron' meant 'flour').

'aleuron' (Greek) passed into Latin/French as words like 'aleurone' and entered English as 'aleurone'; the adjective 'aleuronic' was formed from 'aleurone' in scientific usage, and in modern English it combined with 'low' to form the technical compound 'low-aleuronic'.

Initially 'aleurone' referred to a flour-like layer or material (the aleurone layer of seeds); 'aleuronic' meant 'related to the aleurone layer', and as a compound 'low-aleuronic' came to mean 'having a low amount of aleurone' in agronomy/milling contexts.
