Excerpts from the report: Biphenyl-impregnated paper pads have been used for more than a decade to reduce spoilage in citrus fruits en route to market. Impregnated fruit wrappers are used when the fruit is packed in wooden crates, but kraft paper is used as a biphenyl carrier when fruit is packed in fiberboard cartons. European markets, particularly West Germany, are concerned with additives to foods. They have raised the question as to biphenyl residues on American-grown citrus fruit. This report gives information on: How control of decay can be effectively obtained without excessive biphenyl residue; the effects of temperature, storage time, and carton venting on the rate of loss of biphenyl; and the relationship of these factors to decay, sporulation, and soilage of lemons. (Soilage is dusting of sound fruit with spores of fungi from decaying fruit. )
