Preparing homemade pumpkin seeds is not difficult at all. They can be hulled, processed into ground meal and butter, blended into milk, and cold-pressed for natural oil extraction. When they are in season prepping these little nutritional powerhouses at home for cooking are a great alternative to the store bought kind.
If you want to make pumpkin seed oil at home it will be necessary to use either a cold pressed oil extraction machine or a manual hand crank version. These units range from a few hundred to thousands of dollars for the commercial grade units. Typically 500 grams of seeds yield 160 grams of oil.
Pumpkin seeds and pepitas are generally available locally and in small packages ready for consumption. If you buy at a bulk food store ensure the bins are clean and the seeds give off a fresh scent and not a rancid, oily, grassy or musty one. Inspect for moisture and insect damage and that they are not shriveled.
Organic pumpkins are grown with the healthy advantage of naturally occurring chemicals and pesticides; if the product is certified organic it indicates that it doesn’t contain the harmful by-products that may be present in regularly farmed vegetables. As a consumer you typically pay a bit more for bio-friendly produce.
What are pepitas you might ask, are they simply pumpkin seeds?
Yes they are, however pepitas (which mean “little seeds of squash” in Spanish) don’t have a shell and are found in only select pumpkin varieties. Generally, what you dig out of most types are just basic seeds with shells and all. If you hulled or shelled them you’d find a small seed, or pepita inside. Some of the varieties that yield the shell-less pepitas are Austria Oil, and Gleisdorfer Naked Seeded Pumpkin. You'll find most grocery and bulk food stores sell pepitas raw and roasted.
Do pumpkin seeds go bad? Eventually they will, how long that takes depends on how they were prepared and how they are being stored. For freshness and shelf life they should be saved in sealed containers and refrigerated. While they may stay edible for several months, the seeds may lose some of their peak freshness after about 6-8 weeks.
