Description: A major concern during storage of cereal grains and oilseeds is the possibility of spoilage of the crops. If spoilage occurs it is important to know the rate at which the food is deteriorating. Ideally the storage manager must be aware of the condition of the stored crop at all times and the possible need for instituting preservation treatments that could be increasingly costly with passage of time. Thus, a sensitive method of detection of incipient or ongoing deterioration of stored crops would be a valuable aid to proper food storage management. One possible method of detecting deterioration and moisture content in bulk grain is to measure the electrical resistance of the grain (Gough 1980 Hawrysh 1982 Hodges 1983). The measurement of electrical resistance to deter mine moisture content of grain samples is used in some commercially-produced meters. Resistance cells placed directly in stored grain are also available commercially from at least one company in the U.K. and one company in the U.S.A. The purpose of this laboratory investigation was to determine whether in expensive, simply constructed electrical resistance probes could be used to detect deterioration of stored cereal and oilseed crops caused by changes in moisture con tent and insects and fungi.
