- Yield and acidity indices of sunflower and soybean oils in function of grain drying and storage Paulo Carteri Coradi Alex Eduardo Marchi de Souza Monica Cristina Rezende Zuffo Borges Agrociencias Postharvest processing and quality The aim of this study was to identify the best conditions for drying and storing soybeans and sunflower grains to maintain their quality. In th e first experiment, the soybeans were found to have initial moisture contents of 25 and 19% (w.b.) at different drying air temperatures (75, 90, 105, and 120°C). In the second step, the soybeans were evaluated af ter they were stored in paper bags and plastic polyethylene at temperatures of 3, 10 and 23°C for si x months. In the third experiment, sunflower grains were tested after exposure to drying air temperatures of 45, 55, 65, and 75°C, an d under storage conditions of 25°C and 50%, 20°C and 60%, 30°C and 40% RH over six months in pa per bags and raffia. Drying the sunflower seeds at 45°C and storing them at 30°C an d 40% RH led to higher oil yields and lower acid numbers. The oil that was extracted from the acid numb er was higher for soybean grains that were dried down from initial concentrations of 25% water at a dr ying air temperature of 120° C. The air temperature in storage at 3°C favored for yield and reduction of the soybean oil acidity. 2017 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303050431015 https://www.redalyc.org/journal/3030/303050431015/ https://www.redalyc.org/journal/3030/303050431015/html/ https://www.redalyc.org/journal/3030/303050431015/303050431015.epub https://www.redalyc.org/journal/3030/303050431015/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
