In the microflora of sunflower seeds stored in domestic stores the, <i>Alternaria</i> species dominate, while those of <i>Penicillium, Trichoderma, Stemphylium</i> and <i>Absidia</i> spp. are present in lower numbers. During model tests (cca 20% seed moisture content, 25 °C, 4 weeks storage) the <i>Alternaria</i> species were almost completely eliminated and on the seeds mainly <i>Aspergillus</i> species, characteristic of stores, propagated. The moulds significantly deteriorated the quality of the seed and that of the produced oil and meal (reproductive ability, germinating power, oil content, lipoxygenase enzyme activity, acid value, peroxide value, fatty acid composition, UV absorbance, colour, sensorial properties, as well as the protein content, amino acid composition, colour and the smell of the meal), but no aflatoxin production occurred. The findings offer a comprehensive picture on the multiple destructive effects of incorrect storage.
