Dioscorea opposita Thunb. cv. Tiegun is deeply favored by people as it has high edible value, medicinal value and nutritional value. Relatively concentrated harvest season of Dioscorea opposita Thunb. cv. Tiegun and its thin skin are not conducive to the preservation and long-distance transport. Meanwhile, local yam industry is in extensive form and few enterprises perform deep processing, which lead to limited utilization of yam resources. Therefore, Chenji Dioscorea opposita Thunb. cv. Tiegun should be further processed to improve its additional value, so as to bring certain economic benefits to the Chenji area and increase the economic income of local farmers. Taking Chenji Dioscorea opposita Thunb. cv. Tiegun as an example, this study explored its starch enzymolysis as well as the stability of yam series products, providing a scientific basis for better developing henji Dioscorea opposita Thunb. cv. Tiegun juice. In addition, this work also analyzed the influences of development of Chenji Dioscorea opposita Thunb. cv. Tiegun series products on economic development in Shandong province.
