Abstract

The invention provides a method for producing diosgenin and health wine by utilizing yellow ginger. The method comprises the following steps: washing and drying yellow ginger rhizomes, grinding and screening, performing alcohol extraction, filtering, concentrating, performing acidolysis, and crystallizing so as to obtain finished yam diosgenin; acidizing waste residues, mixing with a sorghum and buckwheat mixture, adding saccharifying enzymes and distiller's yeasts, fermenting in a sealed manner, performing in a conventional distilled liquor production manner, performing harrowing operation, jar fermentation, boiling wine, and packaging, thereby obtaining the health wine product. The fermented waste residues are dried after distillation and then subjected to carbonizing treatment at the temperature of 200-300 DEG C so as to obtain the carbide. The method disclosed by the invention is easy to operate, only the extraction and crystallization-recrystallization technology is used, multiple products are produced by fully utilizing the yellow ginger, the production cost of the yam diosgenin is greatly reduced, the production process is simplified, and high-efficiency large-scale production of the yam diosgenin is ensured. In addition, the yellow ginger wastes are fully utilized and are not directly discharged, and risk of discharging the wastes into the environment is greatly reduced.

Description

technical field [0001] The invention belongs to the field of natural product processing, and relates to a method for comprehensive utilization of turmeric resources, and more specifically relates to a product such as diosgenin and health wine produced from turmeric. Background technique [0002] Turmeric, also known as Dioscorea shield leaf, is a perennial herb of the Dioscoreaceae Dioscorea genus, and it is the species with the highest diosgenin content in the world. Recorded in "Pharmacopia of the People's Republic of China" (2000 edition), the content of diosgenin (commonly known as saponin) in its rhizomes is 1.1% to 16.15%, which is an important pharmaceutical chemical for the synthesis of steroid hormone drugs and steroidal contraceptives raw material. Herbaceous vines. China is the origin of yam yam, and there is a record in the "Shan Hai Jing" more than 2,000 years ago that "Jingshan, looking north to Shaoze, has a lot of grass and yam". Dioscorea shield leaf is t...
