About Pumpkin

Pumpkin seed protein is a plant-based protein isolate derived from the seeds of Cucurbita pepo or related pumpkin species. It contains a complete amino acid profile with notable amounts of arginine, glutamic acid, and branched-chain amino acids (leucine, isoleucine, valine). It is rich in minerals like magnesium, zinc, and iron, and contains bioactive compounds such as phytosterols and tocopherols. The protein is typically produced via mechanical pressing to remove oil, followed by defatting, milling, and protein isolation/concentration processes. It serves as a high-quality vegan protein alternative with additional nutritional benefits beyond basic protein content.
