pumpkin seeds
The green kernel may come from the gymnosperm pumpkin or from the seed after peeling. It is more useful to clarify this than to choose only by color.
Special forms of pumpkin are grown for seeds. A larger fruit does not necessarily produce a better seed yield.
Butternut squash, vegetable pumpkin and snack seeds are different uses of the crop.
History
Styrian oilseed tradition
The Styrian oil pumpkin has a thin seed coat that does not form the usual hard shell. The University of Graz describes its importance for the production of local salad oil.
Breeding for seeds
The researchers compare the timing of ripening, size, color, cracking and oil content of the seeds. For a bar and for an oil, buyer requirements may differ.
Regions and differences
Growing areas and separately noted study
The map shows examples and important areas, not all countries or global market shares. Coordinates are approximate. The origin and characteristics of our batch are confirmed separately.
Styria, Austria
Historic area of butternut squash with thin seed coat.
Gymnosperm is related to the shape of the plant, and not to the mechanical removal of the hard shell.
Specify the name of the variety if the Styrian form is important.
Willamette Valley, Oregon, USA
OSU describes growing seed forms and testing varieties in Corvallis.
The food seed department selects the variety to suit the requirements of the processor.
For snacks, compare the caliber; for the test - the integrity and price of the core.
Zhejiang - research on seed forms, China
A 2023 university study used seeds of different varieties and years from Zhejiang.
This is an endorsement of the diversity of material studied and not a ranking of commercial producers.
Don't determine the grade of a Chinese batch just by looking at the photo.
Types and processing
Gymnosperms
The thin shell remains part of the seed; There is no usual hard husk.
Whole kernels for feeding and processing.
Peeled from seeds with shell
Food seed raw materials are also obtained from ordinary seed forms.
Recipes with the specified mass of pure kernel.
Seeds for oil and snack
The variety and size are selected according to purpose; Requirements for cracking and oil content may vary.
Check the shape and processing method to suit your recipe.
Drying this product
In OSU experiments, seeds were cleaned and dried using a forced air flow. This is post-harvest preparation, not roasting or proof of our batch's technology. About the method
How to choose
- Check the presence of the casing and the cleaning method.
- An unsalted kernel is convenient for baking.
- Color does not indicate country or variety.
