Title VEGETABLE OIL PRODUCTION METHOD AND PRODUCTION DEVICE
Abstract Provided is a vegetable oil production method comprising: (A) a step in which pulverized non-food oilseeds are subjected to extraction using water, and the extract and solid materials are separated; (B) a step in which the solid materials obtained in step (A) are subjected to extraction using a C1-4 alcohol, and the extract and solid materials are separated; and (C) either (i) a step in which the solid materials obtained in step (B) are subjected to extraction using a C5-8 saturated hydrocarbon to obtain a vegetable oil, or (ii) a step in which the solid materials obtained in step (B) are pressed to obtain a vegetable oil. This vegetable oil production method makes it possible to efficiently separate vegetable oil from non-food oilseeds while also obtaining other useful components that have a high added value, thereby increasing the overall commercial viability of oilseeds.
Outline of related art and contending technology BACKGROUND ART
Conventional, a large amount of the biodiesel fuel has been used widely as a raw material for rapeseed oil, soybean oil, palm oil from the biodiesel fuel may be produced, land use change indirectly (Indirect Land Use Change: ILUC) with considering the amount of greenhouse gas, compared to petroleum derived gas oil CO2 be occurrence of revealed that cannot be reduced. Prepared from these raw materials may be used in diesel fuel must be climate-fluctuation reducing solution, the fresh feed has been a problem of the urgent search.
In such a situation, in recent years, non-food southern ocean food tung tree seed oil, tung tree Cantonese and the like, the amount of greenhouse gas emissions associated with ILUC take into account, as compared to fuels of petroleum origin CO2 is reduced as the occurrence of, south-east Asia as a raw material of the biodiesel fuel in cultivated in many countries policy.
On the other hand, non-edible oil such as tung tree southern ocean food seeds include, in addition to vegetable oils, such as vitamin E and phytosterols medical component polysaccharides and the like has been reported (non-patent document 1, non-patent document 2).
