n-Hexane has been generally used as the extraction solvent for soybean extraction. In n-hexane extraction, however, it is difficult to remove solvent from the miscella and meal perfectly at low temperature. The solvent removal is usually carried out at a higher temperature of about 100°C., consequently, quality of the oil and meal extracted with n-hexane becomes inferior. Especially, denaturation of protein in the soybean oil occurs more evidently with the elevated temperature during solvent removal. This study has been made to improve the quality of extracted oil and meal by using liquid butane as the extraction solvent and by processing at lower temperature, about 5060°C. As a result, the liquid butane was useful as the extraction solvent under an optimum extraction condition. Butane-extracted oil has lighter color, low acid value and low lecithin content. The denaturation of protein in the meal does not occur during the solbent-removal process.
