Introduction
Jujube seeds, derived from the fruits of Ziziphus jujuba Mill., have been treasured in traditional medicine for thousands of years, particularly in Asian cultures. These small but mighty seeds pack an impressive array of bioactive compounds that offer remarkable health benefits 1. As modern science continues to validate ancient wisdom, jujube seeds are gaining recognition as a superior superfood with exceptional therapeutic potential.
Belonging to the Rhamnaceae family, the jujube tree is widely cultivated across Asia, America, and the Mediterranean regions. China stands as the world's largest producer, generating approximately 7,464,000 tons in 2019, which represents about 90% of global production 1. With over three million hectares dedicated to jujube cultivation in China alone, the industry generates more than three million tons of jujube seeds annually 1.
