Problems solved by technology

The traditional process of turmeric saponin production is to extract it with gasoline after fermentation and acidolysis, which needs to consume a large amount of hydrochloric acid or sulfuric acid. Substances lead to serious organic pollution of wastewater and become an important source of pollution in turmeric saponin production areas
Due to the limitation of saponin price and environmental protection, it is difficult to make a profit simply extracting saponin from turmeric, so the turmeric saponin industry is facing a survival crisis

Embodiment 1

[0020] Weigh and wash 3 kg of fresh turmeric, add 1 kg of methanol after crushing, centrifuge to decolorize and remove alkaloids to obtain a filter residue, add 1.5 kg of water to the filter residue, cook at 0.1Mp for 0.5 hours until fully cooked, and then cool naturally Add 15 grams of amylase and 0.1 grams of CaCl2 to 90 ° C to liquefy for 0.5 hours, cool the liquefied mash to 60 ° C, add 15 grams of glucoamylase and 0.1 grams of MgCl 2 Saccharify for 8 hours, cool the mash to 34°C and add 4.5 grams of yeast. After 72 hours of fermentation, the alcohol content in the solution is 6.9%, and the conversion rate of starch is 90%. After the solution is distilled, alcohol and glutinous rice are obtained. The yield of saponin extracted by acid hydrolysis of distilled fermented glutinous rice is equivalent to that extracted by traditional process.

Embodiment 2

[0022] Take by weighing 4 kilograms of fresh turmeric, grind it, add 2 kilograms of ethanol, centrifuge decolorize and remove alkaloids to obtain a filter residue, add 3 kilograms of water to the filter residue and boil it at 0.12Mp for 1 hour until it is thoroughly cooked, then naturally cool to Add 25 grams of amylase and 0.3 grams of CaCl at 85°C 2 Liquefy for 0.5 hours, cool the liquefied mash to 50°C, add 25 grams of glucoamylase, 0.3 grams of MgCl 2 Saccharify for 10 hours, cool the mash to 34°C and add 8 grams of yeast. After 96 hours of fermentation, the alcohol content in the solution is 4.6%, and the conversion rate of starch is 91%. After the solution is distilled, alcohol and glutinous rice are obtained. The yield of saponin extracted from the fermented glutinous rice by acid hydrolysis is equivalent to that extracted by traditional technology.

Embodiment 3

[0024] Take by weighing 4 kilograms of fresh turmeric, grind it, add 4 kilograms of methanol, centrifuge decolorize and remove alkaloids to obtain a filter residue, add 2 kilograms of water to the filter residue and cook at 0.15Mp for 0.5 hour until thoroughly cooked, then naturally cool to Add 20 grams of amylase and 0.2 grams of CaCl at 90°C 2 Liquefy for 0.5 hours, cool the liquefied mash to 55°C, add 20 grams of glucoamylase, 0.2 grams of MgCl 2 Saccharify for 6 hours, cool the mash to 34°C and add 6 grams of yeast. After 72 hours of fermentation, the alcohol content in the solution is 6.8%, and the conversion rate of starch is 90%. After the solution is distilled, alcohol and glutinous rice are obtained. The yield of saponin extracted from the fermented glutinous rice by acid hydrolysis is equivalent to that extracted by traditional technology.

Abstract

The invention discloses a making method of alcohol through turmeric, which comprises the following steps: beating the cleaned raw material of turmeric; adding 0.3-1% carbinol or alcohol corresponding to the weight of turmeric; centrifuging to remove pigment and alkaloid in the turmeric slurry to obtain the filtrating slag; adding water into the filtering slag to boil under 0.1-0.2MP; cooling to 80-90 deg. c to add certain amylase and CaCl2 to liquefy sufficiently to obtain the liquefied fermented glutinour rice; cooling the liquefied fermented glutinour rice to 50-60 deg. c to add certain saccharifying enzyme and MgCl2 to saccharify sufficiently to obtain the mash; cooling the saccharified mash to 33-35 deg. c; adding certain yeast to ferment sufficiently; obtaining the matured fermentation liquor; distilling the fermentation liquor to obtain the alcohol and fermented glutinour rice.

Description

technical field [0001] The invention relates to a method for preparing ethanol from turmeric, especially fermented glutinous rice obtained after the ethanol is prepared by the method of the invention can continue to be used to produce saponin. Background technique [0002] Alcohol can be used not only as a raw material for edible alcohol, but also as an organic fuel. It is also a reagent for many chemical synthesis and has a wide range of uses. Alcohol in drinking alcoholic beverages currently on the market is mainly made by fermentation of grain, and the problem of food shortage is becoming increasingly serious, so this type of alcohol will soon be in short supply. [0003] The main way to utilize turmeric is to extract the saponin in turmeric. The traditional process of turmeric saponin production is to extract it with gasoline after fermentation and acidolysis, which needs to consume a large amount of hydrochloric acid or sulfuric acid. Substances lead to serious organi...
