reference example 1

[0060] The anionic resins used in the embodiments of the present invention are all soaked with 2BV, 95% ethanol solution by volume fraction for 24h before use, and then washed with ethanol solution with 95% volume fraction until the effluent is colorless and odorless, and washed with water until After there is no alcohol smell, wash with 4BV of 5% sodium hydroxide solution, then wash with water until neutral, then pickle with 4BV of 5% hydrochloric acid solution, then wash with water until neutral, and finally wash with 4BV of 5% hydrochloric acid solution. Wash with 5% sodium hydroxide solution, and then wash with water until neutral.

Embodiment 1

[0062] (1) Pretreatment and enzymatic hydrolysis: Take 2000kg of fresh Luo Han Guo tubers, wash them with a high-pressure water gun until there is no obvious sediment residue, cut them into pieces, crush them with a hammer crusher, and pass through a 10-mesh sieve to obtain 1950 kg of Luo Han Guo root tubers. Add 2000L of hot water at 60°C, then add 5.85kg of compound enzyme preparation (the mass ratio of cellulase preparation, hemicellulase preparation, acid protease preparation and papain preparation is 2.0:1.0:1.2:0.8), stir, At 60°C, let stand for 2.0 hours for enzymatic hydrolysis, filter with a 40-mesh filter cloth bag, collect the coarse powder, put it in a pressure-resistant storage tank, pass in 0.5MPa steam, and at 120°C, 0.4MPa, steam to inactivate the enzyme for 60s , to obtain 1850kg of enzymatic hydrolysis coarse powder;

[0063] (2) Homogenization and centrifugation: Add 5550kg of hot water at 90°C to the 1850kg of enzymolysis coarse powder obtained in step (1),...

Abstract

A method for extracting starch from Luo Han Guo root, comprising the following steps: (1) take fresh Luo Han Guo root, wash, cut into pieces, crush, sieve, add hot water, add enzyme preparation, stir, stand for enzymolysis, filter, Collect coarse powder and inactivate enzyme; (2) add hot water to homogenate, collect slurry, and centrifugal filter; (3) compound decolorization, concentrate under reduced pressure; (4) add organic solvent, heat and stir, let stand, centrifugal filter, dry, Crush, sieve, and serve. The Luo Han Guo root starch product obtained by the method of the present invention is pure white, the mass content of the starch contained is as high as 85.67%, the yield is as high as 93.1%, has no bitter taste, high nutritional value, stable product quality, and excellent taste, which greatly enriches the quality of Luo Han Guo. Product categories; the method of the invention has simple operation process, short extraction time, low energy consumption and low cost, and can realize continuous large-scale production.

Description

technical field [0001] The invention relates to a method for extracting starch, in particular to a method for extracting starch from Luo Han Guo tubers. Background technique [0002] Luo Han Guo is a perennial vine of Cucurbitaceae. At present, the fruit is more researched and used. The fruit is used as medicine to clear away heat and moisten the lungs, relieve cough, sore throat, and laxative. It is mainly used to extract mogroside as a natural sweetener . However, there are few reports on the research and comprehensive utilization of the roots of Luo Han Guo. The roots of Luo Han Guo are hypertrophic, spindle-shaped or nearly spherical, with a light smell and a bitter taste. Root tubers are rich in nutrients such as starch, soluble sugar, crude fiber and protein. In addition, they also contain cucurbitacin, so they have a bitter taste. The root tuber of Luo Han Guo is used as medicine, which has the effects of warming and removing dampness, dredging collaterals and relie...
