Using an oil press to make your own oils has many advantages, with the most important being that you know exactly what is in the oil. By pressing your own oils you are completely in control of what goes into your oil. Make pure oil with no preservatives and without alterations to the chemical structure.
There are a variety of nuts and seeds that you can extract oil from, each with their own culinary uses and nutritional values. You can use these oils to support your health and well being as well as to enhance your cooking.
Home-pressed oils vs. Store-bought oils
To reduce their intensity and create larger quantities, most oils have are diluted with vegetable oils or cheaper oils. If you take a look at the ingredients of most oils you will notice they are not 100% pure. By pressing your own oils you can create 100% pure oil without dilution.
Make only as much as you need. When pressing your own oil you can make the oil just before using it - resulting in fresh oil every time. The oil will be noticeably richer, flavoursome and fuller tasting, and as a result you will most likely use less oil than you would normally.
By consuming the oil fresh, there is little to none oxidisation therefore the nutrients and enzymes remain intact. It is worth noting that without the added preservatives, some fresh pressed monounsaturated and polyunsaturated oil will not last very long on the shelf. It is therefore best to make as much as you need without the oil turning rancid.
How does oil pressing work?
Expeller pressing is the method of extracting oil with a mechanical press rather than using 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 pulp is expelled separately.
This results in a clean oil, higher in natural colours and flavours. The resulting oils are the more expensive options found in health food stores, which have most likely been extracted using this method.
What can you make with your home extracted oil?
You can use your home pressed natural nut and seed oils for frying, baking or to add flavour to a variety of foods, such as:
- Salad Dressings
- Seasoning for steamed vegetables or fish
