Handling from farm to storage terminal

Grain may be used where it is grown (subsistence farming) or on the opposite side of the world from its growth site (international trade). In either case, to preserve its quality, grain must be kept clean, dry, and free of insect contamination. Artificial or natural drying methods may be used. Insects may be controlled with insecticides. Alternatives include the use of fumigants or inert gases

SUSCEPTIBILITY OF CEREAL MICROFLORA TO OXYGEN DEFICIENCY AND CARBON DIOXIDE CONCENTRATION

Abstract Suscep t.i bi Lf ty to oxygen deficiency of grain microflora was anves ta.gat.ed a.n order to quantify the poseabt l.t ties and limits of airtight storage of wet grains (0.85 < a (water acti Vl. ty) < 0.98). At a ha.gher-than 0.90, V1Z. , a moisture content permitting b~cterlal~Ctlvlty, the maln phenomenon was the development of lactic bacterla, WhlCh could not be l.nhl.bltedby any gaseous composition. These experumerrtaL data conform closely to pr-evaous resul ts obtalned in pllot-scale experlments under al.rtl.ghtconditl0ns. They show the bacterlologlcal and mycological limits of controlled atmosphere storage of wet gral.ns
