unoxidised
Still chemically pure
Unoxidised describes something that has not undergone oxidation—the chemical process where a substance combines with oxygen or loses electrons.
Unoxidised metals retain their original luster without rust or tarnish: unoxidised copper gleams bright orange.
In food science, unoxidised ingredients haven't degraded through exposure to air.
Also spelled unoxidized.
