Abstract China is the largest producer of jujubes in the world, with the Xinjiang region accounting for about 50 % of the total production. However, local jujube processing still relies on traditional methods, leading to reduced industrial efficiency. Research shows that jujube polysaccharides possess various biological properties, such as antioxidant, anti-tumor, and anti-inflammatory activities. Enhancing the extraction of jujube polysaccharides to boost their food, medicinal, and economic value has become an important development direction of the jujube industry. This paper reviews the current research on the active functions of grey jujube polysaccharides, extraction technologies, and recent advancements in their production and application. It systematically introduces both traditional and emerging extraction technologies and summarizes the current state of production and application of grey jujube polysaccharides. The aim is to provide references for other researchers interested in jujube polysaccharides and to extend the value chain of the grey jujube industry.
