Abstract

In this study, first, rapeseed was separated the high quality seed for food oil and the low quality seed for biofuels. Next, laboratory-scale oilseed screw press was used to investigate the effects of choke opening and seed preheating on these rapeseed pressing performance and quality of food oil and biofuels oil. Maximum pressure increased, oil recovery increased, but chlorophyll in rapeseed oil was increased, too. Especially, acid value of the rapeseed oil extracted from low quality seed was high value. For the rapeseed pressing performance, the rapeseed heated by microwaves outputted more oil than that without heating. And the chlorophyll in the rapeseed oil extracted from the rapeseed treated by microwaves was higher than that without heating. The Net Energy Balance ratio of microwave heating press with choke opening set at 8.0 mm is advantage. And the oil pressed this method was good and basically fulfilled the Codex Alimentarius requirements for edible oils.
