without amino acids

Etymology
Etymology Information

'amino-free' originates from modern English, formed by combining the element 'amino-' (from the chemical term 'amino/amine') and the adjective 'free' meaning 'without' or 'not containing'.

Historical Evolution

'amino-' in English derives from the chemical noun 'amine', from German 'Amin' (19th century), which in turn is related to 'ammonia' (Latin/Greek origins). 'Free' comes from Old English 'frēo' meaning 'not in bondage, exempt', and the compound 'amino-free' arose in late 20th century English usage, especially in product labeling, by directly joining the two elements.

Meaning Changes

Initially chemical terms involving 'amino' referred to amine groups or compounds; over time the compounded label 'amino-free' came to be used more broadly in consumer contexts to mean 'without amino acids' or 'does not include amino-acid–based ingredients'.
