We distinguish hot and cold pressed oils. Common oils are hot pressed, which means that seeds are warmed up to be softer and therefore you squeeze more oil out of them. But heat unnecessarily destroys a lot of beneficial substances. That’s why you get lower quality.
You can easily recognize these oils in supermarkets:
- wrapped in a see-through bottles
- no specific smell and taste,
In the process of hot pressing there is a huge loss of both taste and beneficial substances. And that’s a pity, because more and more studies have proved great nutritive value of seed oils.
