Embodiment 1

[0015] Embodiment 1: 500kg konjac powder is dispersed in 10000 liters of mass percent concentration and is 45% ethanol solution, puts into ultrasonic microwave chemical reactor, opens and sets ultrasonic reaction time as 30min, and ultrasonic power is set as 100W, then The microwave action temperature is controlled at 65°C, extract in the reactor for 20 minutes, and stir at a speed of 60r / min at the same time, filter after the reaction is completed, and the filter cake is repeatedly extracted 4 times according to the above steps. After the reaction is completed, the equipment is closed, and then the solvent is filtered off. The filter cake is pulverized into a blast drying oven at 35° C. for drying, and the dried material is pulverized through a 120-mesh sieve to obtain a white powder that is the alkaloid-removed konjac flour.

Embodiment 2

[0016] Embodiment 2: 500kg konjac flour is dispersed in 2000 liters of mass percent concentration and is 90% ethanol solution, puts into ultrasonic microwave chemical reactor, opens and sets ultrasonic reaction time to be 30min, and ultrasonic power is set to 500W, then The microwave action temperature is controlled at 40°C, extracted in the reactor for 5 minutes, and stirred at a speed of 80 r / min at the same time, filtered after the reaction is completed, and the filter cake is repeatedly extracted 3 times according to the above steps. After the reaction is completed, the equipment is closed, and then the solvent is filtered off. The filter cake is crushed into a blast drying oven at 60° C. for drying, and the dried material is crushed through a 120-mesh sieve to obtain a white powder that is the alkaloid-removed konjac flour.

Embodiment 3

[0017] Embodiment 3: 500kg konjac flour is dispersed in 5000 liters of mass percent concentration and is 70% ethanol solution, puts into ultrasonic microwave chemical reactor, opens and sets ultrasonic reaction time to be 30min, and ultrasonic power is set to 300W, then The microwave action temperature is controlled at 55°C, extract in the reactor for 10 minutes, and stir at a speed of 80 r / min at the same time, filter after the reaction is completed, and the filter cake is extracted 4 times according to the above steps, close the equipment after the reaction is completed, and then filter off the solvent. The filter cake is pulverized into a blast drying oven at 90° C. for drying, and the dried material is pulverized through a 120-mesh sieve to obtain a white powder that is alkaloid-removed konjac flour.

Abstract

The invention relates to a method for eliminating alkaloid in konjaku flour. The method integrates a microwave and ultrasonic wave technology and adopts a pure physical method under the synergistic effect of microwave and ultrasonic wave to thoroughly eliminate alkaloid in konjaku flour, the physical and chemical properties and the functional properties of the konjaku flour are not affected, the applicable scope of raw materials is wide, and because of the synergistic effect of the ultrasonic wave and the microwave, the treatment time is greatly shortened and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical fields of medicine, food, daily chemical industry and the like, in particular to a method for eliminating alkaloids in konjac flour. Background technique [0002] Since the 1980s, with the increasing demand for konjac products in the international market, the konjac industry in China has risen rapidly. Driven by the demand for raw materials in the market, China is increasingly becoming the center of the production and supply of konjac raw materials in the world. [0003] Konjac is processed to obtain konjac flour, a form of konjac glucomannan. Konjac glucomannan is an ideal dietary fiber, mainly used to make konjac food. The food processed with it has the characteristics of low heat and low fat, which can hinder the excessive absorption of sugar, fat and cholesterol by the human body, hinder the invasion of harmful substances, and have a good effect on hypertension, high cholesterol, cardiovascular disease, diab...
