Abstract
The storage of sunflower seeds in an adequate position to guarantee the quality and regulate the supply of raw material for the industries for the production of oils and bran. The objective of this study was to evaluate the yield of sunflower seed oil after drying and during storage in three conditions (25 0 C and 50%, 20% and 60 0 C, 30 0 C and 40%) in different packing (permeable and impermeable). Quality assessments of seed and oil yield were performed in zero, three and six months of storage times and analyzed by the average test were compared by Tukey test at 5 % probability. In storage there were greater reductions in oil, with the increase of storage temperature of 20 °C to 30 °C and reducing the relative humidity from 60% to 40%. Under these conditions, the yield of oil decreased from 65% to 17%. Waterproof packaging positively influenced the quality of sunflower seeds stored. The conditions of 25 °C and 50% RH air storage were more favorable for the quality of the seeds. The increase in time of storage under conditions of 30 °C and 40% RH air adversely affecting the quality of seeds. It was concluded that to increase the oil yield of sunflower seeds, the best storage conditions were 25 0 C and 50% RH air.
