摘要: Lipids are traditionally removed from seeds by mechanical crushing and solvent extraction. During the process oilseed is cleaned, cracked, flaked, cooked before entering a screw press. Seventy-five percent of oil sunflower can be extracted crushing, fatty cake then contains about 15% oil. The levels remaining in reduced to less than 2% However, crude has refined as it many impurities approximately 600 ppm phosphorus. A new process, which pressed twin-screw extruder, examined here. profile was first optimized. Oleic were crushed 80% removed. resultant good quality, with acid numbers below 2 mg KOH/g total phosphorus contents 100 ppm. influence pressing temperature fresh seed moisture content determined.
