A study of the radiation-induced formation of carbonyl compounds in solid starch by means of precipitation with 2, 4-dinitrophenylhydrazine and subsequent analysis of the hydrazones by gas chromatograph has been performed. formation of carbonyl groups was found to increase linearly with increasing doses up to about 2$\times$10$^{21}$ eV/g. Generally, at least 5 different peaks can be detected including formaldehyde and acetaldehyde.
