One of the most fascinating things about Pumpkin Seed Oil is the colour! When first looking at it most people think it looks like balsamic vinegar as it can look almost black in a clear glass bottle, however if you look at it from the right angle it can have a reddish sheen to it and THEN when you put it on a salad or white plate it comes up a very dark green colour! So what colour actually is it?

Well, its actually two colours. The technical term for this type of colouring is Dichromatic or Polychomatic. A study at the University of Slovenia found that "When the layer of oil is less than 0.7 millimeter thick," the study notes, "the oil appears bright green, and in [a] layer thicker than this, it appears bright red." It all has to do with light waves passing through the oil and how our eye receptors process colours. For more detail visit our website or http://www.sciam.com/article.cfm?id=traffic-light-on-a-spoon

We press all our oil ourselves in the traditional cold press way with lots of pressure (as done for the last 300 years in Styria). Our oil is pure pumpkin seed oil which can be identified by its deep colour consistency. Some  oils (especially if they are about half the price) are not pure and will not have the deep colour or same flavour as they have usually been processed with another type of white oil (eg canola or sunflower) to make them cheaper.

There can be many differences in flavours and quality due to the processing and addition (or not) of white oil. The seed is gently heated before being pressed - higher heat produces higher yield, higher roasted nutty flavour, lower nutritional value, lower cost and vice versa. The gentle heating is necessary as it releases the oil from the seed and from tests we have done, it also increases some of the nutrient transfer into the oil instead of remaining with the seed residue.

Another way I believe you may be able to get an idea of purity of pumpkin seed oil is to look at the Omega content. Pure pumpkin seed oil shows negligible amounts of Omega 3 (Linolenic Acid) and high Omega 6 (Linoleic Acid). There are plenty of websites that say pumpkin seed oil is a good source of Omega 3 however this is from the addition of another oil during extraction. We know a  manufacturer who adds Canola  oil specifically to increase the Omega 3 content. Omega 3 is an essential fatty acid and necessary in our diets. This may show it is not pure, however the benefits of getting some Omega 3 outweigh the fact that it is not pure.
 
Pumpkin seed oil that is not 100% pure does not mean it is not good - not at all,  as it can actually be enhanced through shelf-life, taste or nutrients with other oils. It also depends what you are using it for; flavour or nutrition? If you find a lower priced oil and you just want good flavour and it has it, then use it. If you want the nutritional quality then remember you get what you pay for.

Pumpkin seed oil with an Omega 3 content will go rancid more quickly as that is the nature of Omega 3.  Flax seed oil is a great source of Omega 3 and if it is fresh and good quality then it can last a good 3 months in the fridge. Pumpkin seed oil with a high Omega 6 content will last in the right conditions for 2 years. A small amount (eg 80ml) in a dipping bowl in the sun and airy place will go rancid in a couple of hours, that's what its meant to do (the reasons I will explain in another blog!).  If you are not sure what a rancid oil tastes like, put some on a spoon and leave it on the bench in an airy spot for a few hours and then dip your finger in to try it and you'll know.

To sum it all up: eating quality oils will help your health and well-being. The money spent on a good quality oil (and food in general) will be saved in other areas (expensive vitamin pills, doctors visits etc). Buy good quality and you'll get the flavour and nutritional benefits.



(Regarding the 250ml picture in the shopping cart of two different looking bottles. The orange label is our existing one and the other a design option similar (we have changed it a bit since this photo was taken) to a new label we will be using soon to make all our products come under the one consistent branding of 'Australian Pumpkin Seed Company'. We also have the 500ml size. )
