In this study the influence of solvent, temperature and the extraction time on the extractability of total polyphenols from milled soybeans variety “Ika” were investigated. The study was performed in order to select the suitable solvent (water; as well as 50, 60, 70 and 80% of aqueous ethanol solution) for achieving the highest yield of total polyphenols from soybeans at 50 °C after 60 minutes of the extraction process. The most effective solvent (50% aqueous ethanol solution) was used for monitoring the kinetics and modelling of solid – liquid extraction of total polyphenols from soybeans, mean particles size 0.4586 mm at solid – liquid ratio 20 mL/g. The total polyphenol content was investigated at different temperatures (26 °C, 40 °C, 50 °C, 60 °C, 70 °C and 80 °C) during 120 minutes of the extraction process. The total polyphenols content in soybean extract was determined spectrophotometrically using Folin-Ciocalteu micro-methods. The possibility of applying different mathematical models (Peleg, Page and Logarithmic model) to describe the kinetic of solid-liquid extraction process of total polyphenols from milled soybeans variety "Ika" was studied as well. The results exhibited the significant influence of solvent and temperature on the kinetics and extraction yield of total polyphenols from soybeans variety "Ika". The best extraction yield of total polyphenols was obtained using 50% aqueous ethanol solution at 80 °C after 120 minutes (4.322 mg GAE/gdb). The extraction yield of total polyphenols in soybean extracts was increased with increasing extraction temperature and extended duration of the extraction process. The applied mathematical models showed good agreement with experimental results, which allows their application in modelling and optimization of solid-liquid extraction process of total polyphenols from soybeans.
