Volatile smelling compounds of freezed egg white, freshness of which was kept by freezed storage, were collected by steam-distillation. After DNP-hydrazones of volatile carbonyl compounds were separated into four classes by column chromatography, DNP-hydrazones contained in each class were separated by thin layer chromatography. Rf and melting point of recrystalized compounds were compared with those of authentic compounds. Volatile basic compounds were collected as hydrochlorides and detected by paper and thin layer chromatography.
Acetone, acetaldehyde, formaldehyde, 2-pentanone, 2-butanone diacetyl except two unknown compounds as volatile carbonyl compounds, and ammonia, methylamine, dime-thylamine and putrescine as volatile basic compounds were tentatively identified.
Correlations between these compounds and smell of freezed egg white were discussed.
