The BioChef Vega Oil Press Machine will efficiently extract pure oil from:
NUTS – Almond, Brazil, Cashew, Hazelnuts, Macadamia, Peanut, Pinenut, Pistachio, Walnut
SEEDS – Sesame, Flaxseed / Linseed, Hempseeds, Sunflower, Pumpkin
BENEFITS OF PRESSING YOUR OWN OIL
Making your own oils using the expeller press method of the BioChef Vega Oil Press has many advantages with the most important being that you know exactly what is in the oil.
Expeller pressing is the method of extracting oil with a mechanical press rather than through a chemical extraction process. The expeller press is a screw type machine which presses the nuts and seeds through a barrel and creates friction and pressure to compress the ingredients. The oil falls through small openings while the pulp is expelled separately.
This results in a clean oil, higher in natural colours and flavours. The more expensive oils found in health food stores have probably been extracted by this method.
Solvent extraction is achieved through the grinding of nuts and seeds. The ground seed or cake is then washed with a petroleum distillate (the most common chemical used is hexane) which releases the oil in the seed. The solvent is then “flashed off” by heating the oil in a sealed chamber. The oil/ solvent blend is next heated to 212º F (100º C) to distill off the solvent.
Refining is an optional step in nut oil production and is introduced to extend shelf life. Depending on the method and objective, it may include further steps of bleaching and deodorizing. Refined oils are often less flavourful but better suited for high temperature cooking.
Most nuts are high in polyunsaturated fats which makes them susceptible to oxidative damage so it’s best to keep freshly pressed oil from your BioChef Oil Press in dark bottles in a cool place or in the fridge.
