Oil Specification

Every Cocoguru oil starts as dried coconut and ends as oil with nothing taken out and nothing put in. This page sets out what goes into the oil, how each variety is made, and the laboratory figures behind it, so that you can check our claims against the numbers.

What goes in, and what never does

Only coconut

The only ingredient is coconut, in the form of copra or dried coconut.

Nothing added

No perfumes, preservatives, antioxidants, anti-foaming agents or other edible oils. No argemone oil, no mineral oils.

Never refined

Our oils are unrefined. They are pressed, filtered and packed, with no bleaching, deodorising or chemical treatment.

How each oil is made

The three oils differ in three ways. Roasted and Cold Pressed oils are made from edible copra, while Lite is made from milling copra. Roasted oil is made from copra that has been roasted before pressing, which gives it its golden colour and its roasted aroma. And Cold Pressed oil is crushed in a single stage, while Roasted and Lite oils go through two.

Laboratory results

The table compares the three oils with the limits set by the Food Safety and Standards Regulations. A figure inside the limit means the oil meets the standard for that test.

Reading the numbers

Each test answers a different question about the oil. Open any item for a plain explanation.

Free fatty acid and acid value

Both measure how much of the oil has broken down into free acids. Fresh copra handled well gives a low figure, while old or damaged copra gives a higher one. Free fatty acid is reported as lauric acid because that is the main acid in coconut oil.

Peroxide value

This detects the first products of oxidation, the early stage of rancidity. Fresh oil reads close to zero.

Iodine value

This measures how unsaturated an oil is. Coconut oil is highly saturated, so its figure is low, between 7.5 and 10. Oils mixed with other vegetable oils read higher.

Saponification and Polenske values

Coconut oil is rich in short and medium chain fatty acids, which gives it a high saponification value and a high Polenske value. Other oils score much lower on both, so these two figures help show that the oil is pure coconut oil.

Refractive index

This shows how much light bends as it passes through the oil. For genuine coconut oil it stays within a narrow band.

Specific gravity

A specific gravity of 0.91 means the density of coconut oil is about 0.91 grams per ml, so a litre weighs about 910 grams, lighter than water. It is also why a 5 litre jerry can holds about 4.55 kg.

Unsaponifiable matter

This is the small part of the oil that does not turn into soap, such as natural plant sterols. The standard caps it at 1.0%.

Moisture

This is the water content. Very low moisture helps the oil stay stable.

Good to know

Coconut oil sets solid below about 25°C. This is natural and not a sign of poor quality, and it turns liquid again at normal room warmth.
