Embodiment 1

[0025] The method for efficiently extracting burdock inulin described in this embodiment comprises the following steps:

[0026] (1) Get 1 kg of fresh burdock root after cleaning and drying, add 1 kg of water and make pulp at normal temperature to obtain 2 kg of burdock slurry, and set aside;

[0027] (2) Add 10 kg of water to the gained burdock slurry and mix evenly at normal temperature to obtain a burdock mixed solution;

[0028] (3) Add 20 g of L-valine nitrate to the obtained burdock mixed solution, mix well, and carry out standing extraction at 50° C. for 30 min to obtain the desired extract containing burdock inulin; according to the method in the prior art Measure the content of burdock inulin in the extract, and calculate that in the extract, the extraction efficiency of the inulin is 108.32mg / g fresh burdock;

[0029] (4) Collect the extract prepared in step (3), filter while hot and collect the filtrate;

[0030] (5) Evaporating and concentrating the obtained filt...

Embodiment 2

[0033] The method for efficiently extracting burdock inulin described in this embodiment comprises the following steps:

[0034] (1) Get 1 kg of fresh burdock root after cleaning and drying, add 2 kg of water and make slurry at normal temperature to obtain 3 kg of burdock slurry, and set aside;

[0035] (2) Add 9 kg of water to the gained burdock slurry and mix evenly at normal temperature to obtain a burdock mixed solution;

[0036] (3) Add 50 g of L-valine nitrate to the obtained burdock mixed solution, mix well, and carry out static extraction at 60° C. for 30 min to obtain the desired extract containing burdock inulin; according to the method in the prior art Measure the content of burdock inulin in the extract, and calculate that in the extract, the extraction efficiency of the inulin is 115.27mg / g fresh burdock;

[0037] (4) Collect the extract prepared in step (3), filter while hot and collect the filtrate;

[0038] (5) The obtained filtrate is evaporated and concentr...

Abstract

The invention belongs to the technical field of natural active component extraction and particularly relates to a method of high-effectively extracting burdock inulin from burdock roots. In the methoda common water extraction method is used for extraction from burdock roots; during extraction, a selected amino acid ionic liquid is added to achieve high-effective extraction to the burdock inulin at low temperature. Meanwhile, extraction time is effectively reduced and extraction efficiency of the burdock inulin is greatly increased, thereby effectively saving energy consumption and productioncost.

Description

technical field [0001] The invention belongs to the technical field of extracting natural active ingredients, and in particular relates to a method for efficiently extracting burdock inulin from burdock. Background technique [0002] Burdock, also known as Eshi, Dalizi, American ginseng, oriental burdock, etc., is the fruit of the Compositae plant burdock. When the fruit is ripe in August-September every year, it is collected in batches, and the fruit is dried after drying to remove impurities. It can be used as medicine until it is completely dry. According to testing, burdock is rich in inulin, cellulose, protein, calcium, phosphorus, iron and other vitamins and minerals needed by the human body, especially the content of carotene is 150 times higher than that of carrots, and the content of protein and calcium is also 150 times higher than that of carrots. The first root crops. Burdock root contains inulin and volatile oil, arctic acid, various polyphenols and aldehydes,...
