Embodiment 1

[0024] Extraction process of the present invention comprises the following steps:

[0025] Cleaning: remove impurities from the chicory rhizomes and wash them with water;

[0026] Slicing: Cut the cleaned chicory rhizomes into slices;

[0027] Drying and pulverizing: drying the chicory rhizome processed into slices for 2 hours, controlling the temperature at 80° C., and pulverizing to obtain pulverized chicory rhizome A;

[0028] Extraction and filtration: the pulverized chicory rhizome A is reflux extracted 3 times with 50% ethanol, the amount of ethanol is 8 times, 6 times and 6 times of the weight of raw material A respectively, and the extraction time is 2 hours, 1 hour and 1 hour respectively, and combined The extract was filtered to obtain filtrate B;

[0029] Heating to reflux: add decolorizing agent magnesium oxide according to 5% of the volume of filtrate B, heat to reflux for 3 hours, filter to obtain filtrate C;

[0030] Concentration and drying: Concentrate the ...

Embodiment 2

[0032] In the dry crushing step, dry for 0.5 hours, and the temperature is controlled at 50°C; in the extraction and filtration step, use 10% ethanol to reflux and extract once, the amount of ethanol is twice the weight of raw material A, and the extraction time is 0.5 hours; heat to reflux In the step, add the decolorizing agent aluminum oxide according to 0.1% of the volume of the filtrate B, and heat and reflux for 0.1 hour; in the concentration and drying step, concentrate under reduced pressure at 1 mm Hg, dry in vacuum, and control the water content to 2%, and the others are the same as in the embodiment 1.

Embodiment 3

[0034] In the dry crushing step, dry for 10 hours, and the temperature is controlled at 100°C; in the extraction and filtration step, reflux extraction with 95% ethanol for 5 times, the amount of ethanol each time is 15 times the weight of raw material A, and the extraction time is 5 hours ; In the heating and reflux step, add the decolorant activated carbon according to 50% of the volume of the filtrate B, and heat and reflux for 10 hours; Step is with embodiment 1.

Description

technical field [0001] The invention relates to a plant extraction process, in particular to a preparation process for extracting inulin from chicory roots, which belongs to the chemical extraction process. Background technique [0002] Chicory (also known as European Chicory) is a perennial herb of Compositae, native to Europe, and widely used as raw material for feed and vegetable sugar production abroad. After the introduction in my country in the 1980s, a large-leaf variety was cultivated. Because of its excellent quality, it has become the most promising new breed of feed and economic crops. [0003] Chicory has a wide range of uses. For example, it is used in aquaculture. Because of its excellent palatability, all poultry and grass carp love to eat it. It is a high-quality green fodder; High-quality edible mushroom base material; rich inulin and spices can be extracted from the rhizome. [0004] Modern studies have proved that chicory extract can significantly reduce...
