[0002] Jerusalem artichoke (Helianthus tuberosus), also known as Chinese artichoke and potato artichoke, is a plant rich in various nutrients. In particular, it contains abundant dietary fiber, antioxidants, minerals, water-soluble polysaccharides (such as inulin), etc., and is widely used in the fields of food, medicine, and health products. The nutrients of Jerusalem artichoke have significant health benefits for the human body, such as improving intestinal function, regulating blood sugar levels, enhancing immunity, etc., and it is therefore known as the "green nutritious food". Traditionally, the extraction of Jerusalem artichoke nutrients mostly uses methods such as boiling and soaking.
