Abstract
The invention discloses a method for extracting inulin, and belongs to the technical field of chemical extraction. The method comprises the following specific steps: cleaning jerusalem artichoke; peeling off; slicing; drying; crushing; adding water to be dissolved; extracting through microwave; digesting through hot water to obtain coarse extracted liquid; feeding the coarse extracted liquid into an ionic exchange resin tower to discolor so as to obtain a refined inulin solution; concentrating by pressure reduction; freezing and drying to obtain inulin. The method is short in extraction time; the extracted inulin is high in purity and degree of polymerization.
Description
Technical field
The present invention relates to chemical industry extractive technique field, especially a kind of extracting method of inulin.
Background technology
Inulin, has another name called synanthrin, is the mixture of a class natural fruit glycan, is mainly derived from the Liliaceae in 11 sections such as the composite family in dicotyledons, campanulaceae, Gentianaceae and monocotyledons, grass tree section.Inulin is very good functional food ingredient, is also the raw material producing the products such as oligofructose, polyfructosan, high fructose syrup, crystal diabetin simultaneously.At present, the extraction of inulin mainly with jerusalem artichoke, witloof and Folium Agaves variegatae for raw material, adopt organic solvent lixiviate, the method for hot water extraction or biological enzyme lixiviate extracts inulin, the problems such as it is lower that these methods exist extraction efficiency, and gained inulin purity is low, the polymerization degree is low.
Summary of the invention
The object of this invention is to provide a kind of extracting method of inulin, this method can solve the problem that extraction efficiency is lower and gained inulin purity is low, the polymerization degree is low.
In order to solve the problem, the technical solution used in the present invention is: a kind of extracting method of inulin, comprises the following steps:
The impurity of A, removing jerusalem artichoke, use clear water wash clean, peeling, section, dry, pulverize, obtain 70 order ~ 100 order dry powder;
B, described dry powder to be dissolved in water, then to adopt microwave extracting to extract; Wherein, the mass ratio of described water and described dry powder is 9 ~ 10:1, and described microwave extracting power is 500 watts ~ 550 watts, and the microwave extracting time is 3 minutes ~ 5 minutes;
C, hot water extraction 40 minutes ~ 60 minutes, obtain crude extract; Wherein, the temperature of described hot water is 70 DEG C ~ 90 DEG C;
D, described crude extract is passed into exchange resin tower carry out desolventing technology, obtain the jerusalem artichoke solution refined; Wherein, bleaching time is 2 hours ~ 2.5 hours;
E, described refining jerusalem artichoke solution is carried out concentrating under reduced pressure, lyophilize, obtain inulin.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This technique adopts the method for microwave technology assisted extraction,
1, the present invention adopts microwave extracting in conjunction with the method for hot water extraction, shorten extraction time, improve the extraction efficiency of inulin, and the biological activity extracting the inulin of gained is good, solubleness is high.
2, energy-conservation, efficient, the non-secondary pollution of the present invention, and easily manipulate, products obtained therefrom stable in properties, purity are high, the polymerization degree is high.
3, the present invention adopts ion exchange resin to carry out desolventing technology, and decolorizing effect is better.
