Abstract

ABSTRACT: Concern over environment, safety and cost encourages development of separating edible oils by an aqueous process. An advanced pilot method of separating peanut oils based on aqueous extraction was established in this study, which used 1.5:10 liquid-to-peanut seed kernel slurry ratio with addition of 1 g sodium chloride/100 g slurry, agitation at 64℃. It recovered 96.1 ± 0.2% peanut oils with their quality met Chinese national standard for first class refined oil and the dried residue can be directly used in food industry. No waste was produced during aqueous extraction of oil. Conditions affecting the efficiency of aqueous extraction were verified.
