The ugly truth about refined oil

Refined - when you see this word positive images come to mind, right?


However, the refining process involves treating with acid, bleaching, neutralising, filtering, and deodorising—all of which require chemicals. After refining, the oil may have a longer shelf life and a consistent colour and odour, but it also retains chemical residues.


Even worse, refining oxidises the oil, creating trans-fatty acids, which have been strongly linked to heart disease.

Additionally, the high temperatures used in refining destroy many of the oil’s natural nutrients. In contrast, physically pressed oils retain essential nutrients, making them a healthier choice. Refined oil is cheaper than physically pressed oil— this however, comes at a cost to our health.


 Common refined oils are:

  • Soybean oil

  • Palm oil

  • Corn oil


At Emma Basic, refined oil is banned in our sourcing policy. Although we have one product that contains RSPO*palm oil, we are working towards a better alternative.

Which oils are typically not refined?


  • Extra virgin cold-pressed oil

  • Toasted pressed sesame oil

  • Butter made solely from milk

  • Coconut oil


Emma Basic Toasted Sesame Oil is physically pressed from sesame seeds, not chemically refined, because we believe in keeping things natural and nutritious.


*The Roundtable on Sustainable Palm Oil was established in 2004 with the objective of promoting the growth and use of sustainable palm oil products through global standards
