My bag of Simply7™ Quinoa chips is based on quinoa flour and contains a significant amount of added starch. It claims to have 9 grams of protein/12 grams of carbs, a 3:4 ratio.

enter image description here

However, pure Quinoa has only 8 g protein per 34 grams non-fiber carbs, see: http://nutritiondata.self.com/facts/cereal-grains-and-pasta/10352/2 This is a less than a 1:4 ratio. There are no other ingredients that add a significant amount of protein. Does it really have that much protein?

    Something similar shows up in the analysis I did in skeptics.stackexchange.com/questions/22991/… on Quinoa Flakes. It could be part of a refinement process. – Sean Duggan Oct 3 '14 at 17:40
  • There may also be different varieties of quinoa: perhaps the chips use a variety that is higher in protein than the one used to calculate the figures you found. – Nate Eldredge Oct 5 '14 at 3:01
  • @Sean: in your example the nutrition between the two examples is similar, there is just more overall "stuff" (non-water) in the Purcell product than the reference. My example is very, very different: the 9 grams of protein is way too high AND there are carby additives such as corn starch. – Kevin Kostlan Oct 6 '14 at 14:37
  • @ Eldredge: A variant with well over 3 times the protein:carb ratio? Is this even possible? – Kevin Kostlan Oct 6 '14 at 14:44

    Your label for the chips contains almost no water. The link you provide is cooked, which is 2:1 water:quinoa by volume. To my recollection dry quinoa floats when first put into water and therefore is less dense. I expect this explains a bunch of the variation you see. – msw Oct 6 '14 at 23:15
