Pumpkin seed protein
Pumpkin seed protein is made from pumpkin seeds (Cucurbita pepo), often hull-less varieties grown for their seeds. The seeds are pressed to remove most of the oil, and the press cake is milled and sifted into a powder of roughly 55 to 65% protein; some suppliers make higher-protein grades by further separation. The powder is green to gray-green with a nutty taste and is used in plant protein blends, bars and baked goods.
Suppliers sell different products under the same name. Specify the one you need.
Milled press cake at about 55 to 65% protein, with fiber and some residual oil.
Grades of about 70% protein or more, made by sifting or wet processing.
Made from certified organic seed, a common offering for this ingredient.
Made from sprouted seed or with a fermentation step, sold for flavor and texture differences.
Compare each result with your own specification when the lot arrives.
Store sealed, cool and away from light and air, because the residual oil can go rancid. Shelf life follows the supplier's specification, with sensory or peroxide checks on older stock.
Record protein and cadmium results for each lot and keep the seed origin, since metal levels vary by growing region. Color can vary noticeably between lots.
