[A laboratory study of the possibility of benzpyrene penetration into wheat germ using different means of drying the products of combustion].
Possible accumulation of benzpyrene in wheat grain during its drying by means of a heat-carrying agent (air diluted combustion products) containing this carcinogen was studied in a laboratory set-up. With benzpyrene contained in the heat-carrier in an amount of 0.12 gamma/m3 this carcinogen was amassing in the grain with all conditions and methods of drying under study. An increased benzpyrene content in the grain by comparison with the background one was noted under optimal conditions of drying in a solid layer, boiling layer and in a suspended state by as much as 23, 11 and 3 times respectively. On the basis of these and literature data a conclusion is drawn that grain may be dried in suspended state (recirculation dryers) under definite, parctically realizable conditions without accumulation of benzpyrene therein.
