Abstract:

Tree nuts such as pistachios (Pistacia vera), almonds (Prunus dulcis) and walnuts (Juglans regia) are major crops in the state of California, with an aggregate annual value in excess of $1.4 billion. Under certain conditions these nuts may be infected by various strains of Aspergillus flavus and A. parasiticus, resulting in biosynthesis and accumulation of mycotoxins detrimental to quality and food safety. The carcinogenicity in animals of the primary metabolites, the aflatoxins, has resulted in establishment of tolerance levels. In the U.S. a maximum guidance level limit of 20 ng/g (20 ppb) for nuts intended for human consumption has been set by the Food and Drug Administration, while standards imposed by importing countries are 10 ng/g or less. Phytochemical constituents which are anti-aflatoxigenic have been isolated and identified from pistachios and walnuts, consisting of anacardic acids and naphthoquinones, respectively, and their possible mode of action is described.
