Problems solved by technology

[0004] The invention solves the problem that the turmeric processing industry can only extract saponin from turmeric for a long time, and cannot comprehensively utilize polysaccharides such as starch and fiber and other organic matter, resulting in low resource utilization, and the acid hydrolysis wastewater produced in large quantities has caused serious environmental problems. Pollution, unable to achieve clean production

Embodiment Construction

[0008] Below in conjunction with embodiment the present invention is described in further detail:

[0009] The production process of the present invention is (1) washing: the fresh turmeric is washed with clear water to clean the silt. (2) Pulverization: add water to the fresh ginger that has been washed to make the weight of fresh ginger 50∽70%. powder, add 4 times the warm water of about 40°C and soak for 3∽4h). (3) Pre-fermentation: The fine powder slurry is put into a stirring fermentation tank, and the pre-fermentation is carried out at 38∽50°C for 48 hours, and the material is discharged. (4) One-time acid hydrolysis: pump the pre-fermented slurry into the hydrolysis tank, add hydrochloric acid or sulfuric acid, adjust the pH to 1.2-1.5, ventilate, heat and pressurize, hydrolyze for 40-60min at a gauge pressure of 0.20∽0.28Mpa, and test The starch is fully saccharified and discharged. (5) Filtration: separate the slag and acid-containing sugar liquid from the primary ...

Abstract

The present invention relates to biochemical technology, and is especially clean production process for extracting peltate yam saponin resource and utilizing comprehensively. Peltate yam is fermented and twice hydrolyzed to make the contained polysaccharide converted into water soluble organic matter capable of being used as the industrial material for over hundred kinds of product. The residue is dried and solvent extracted to obtain saponin, the slag after extraction is used in producing organic fertilizer, the effluent is used as culture medium for photosynthetic bacteria so as to produce photosynthetic bacteria for feed and food, and the filtered water is aerobic degraded before exhausting. The present invention utilizes peltate yam comprehensively.

Description

(1) Technical field [0001] The invention relates to a biochemical technology, in particular to a new clean production process for comprehensive utilization of saponin resources extracted from turmeric. (2) Background technology [0002] At present, in the process of extracting saponin from turmeric, there is no new process with high production efficiency, simple process, easy operation, comprehensive utilization of polysaccharides and other water-soluble organic substances in turmeric, no pollution, and clean production. (4) Contents of the invention [0003] The object of the present invention is to provide a new process for comprehensive utilization of turmeric extract saponin resources which is pollution-free, clean production and can comprehensively utilize additional products in the turmeric extraction process. [0004] The invention solves the problem that the turmeric processing industry can only extract saponin from turme...
