I have a very old copy of "Calories and Carbohydrates" by Barbara Kraus - it lists pumpkin seeds both hulled and unhulled - (maybe there is a machine somewhere in pumpkinland that does this???)

• Pumpkin seeds whole 4 oz by weigh - 12.6 carbs and 464 calories
• Pumpkin seeds Hulled 4 oz in weight - 17.00 carbs and 627 calories

Since its by weight I imagine that would be a lot of pumpkin seeds.


Thinking back - after the seeds are roasted - if you do them long enough - the outline of a small kernel is visible through the larger tear shaped papery hull - . Maybe a machine can heat them something like a corn popper and then the kernels could be mechanically seperated from the hulls???
