The method greatly reduces energy consumption and water consumption during the inulin extraction process, at the same time, the inulin extraction rate can reach more than 85 percent, the inulin is pure in colour, the purity is higher than or equal to 92 percent, and ash content is less than or equal to 0.25 percent, therefore, the comprehensive economic benefit is higher.
Description
Technical field
The present invention relates to new resource food processing technique field, particularly produce the method for inulin with Jerusalem artichoke raw material.
Background technology
Inulin (Inulin) derives from the plant such as jerusalem artichoke, witloof, is a kind of functional Polylevulosan, is also unique water-soluble dietary fibre.Inulin connects generation by D-fructofuranose molecule with β-(2,1) glycosidic link, and on this chain, major part is fructose, has a glucose at end, makes inulin have different character.Inulin has reducing blood-fat, improves intestinal environment, promote proliferation of probiotics, anti-ly treat constipation, prevent colon cancer, promote mineral absorption, obesity prevention, do not cause blood glucose fluctuation, can be used as the physiological functions such as diabetes patient.Inulin, as a kind of functional ingredient of pure natural, has been accessory substance by more than 20, world state approval, has been widely used in milk-product, beverage, low-fat low-calorie food, bakes and banks up with earth in food, protective foods.Within 2009, inulin is approved as new resource food by the Ministry of Health of China.
Inulin processing technology mainly contains hot dipping extraction of the juice, two carbon method and the coupling of resin purification method, ultra-filtration technique, countercurrent extraction technology etc.In actually operating, hot dipping extraction of the juice efficiency is low, water consumption is large; The decolouring of two carbon method can cause a large amount of wastes of material; Resin purification adopts reinforcing yin essence resin cation (R.C.) and weak zwitterion resin to be used in conjunction the object reaching desalination usually, and material can be caused damage by resin absorption, affects inulin yield.Although countercurrent extraction technology efficiency is higher, facility investment is higher, and in equipment running process, energy consumption is higher.In a word, traditional technology at extraction yield, de-monose, decolour, remove mineral substance etc. in there are some problems, there is the shortcomings such as water consumption is large, power consumption is higher, extraction yield is lower, operation is longer, cost is higher.The application of countercurrent extraction technology in inulin extracts of inulin is a much progress of industry, but also there is the higher shortcoming of energy consumption.
Summary of the invention
The object of this invention is to provide a kind of technique of producing inulin, solve the shortcomings such as prior art water consumption is large, power consumption is higher, extraction yield is lower, operation is longer, cost is higher.
Technical scheme of the present invention comprises the following steps:
(1) jerusalem artichoke juice and jerusalem artichoke slag is collected respectively after, being squeezed the juice by the jerusalem artichoke of cleaning decortication;
(2), by jerusalem artichoke slag add water and stir extraction, filter and obtain extracting solution and jerusalem artichoke slag filter cake;
(3), merge jerusalem artichoke juice and extracting solution, filtering suspension insoluble impurities obtains total extracting solution excessively;
(4), by total extracting solution successively after removal of impurities, decolouring, filtration, nanofiltration membrane is adopted to concentrate; Concentrated solution carries out sterilizing after strong cation-exchanging resin and weak anion exchange resin desalination; Solution after sterilizing obtains inulin after carrying out drying.
Such scheme also comprises following optimal way:
Described step (1) is squeezed the juice and is adopted screw extrusion juice extractor.
Described step (2) water is pure water, and its add-on is no more than the twice of jerusalem artichoke slag weight; Stir that the temperature extracted is 70-100 DEG C, the time is 20-80 minute.
In described step (4), removal of impurities adopts lime carbonating method, and decolouring adopts activated carbon decolorizing method, and nanofiltration membrane adopts the daltonian nanofiltration membrane of molecular weight cut-off 200-300, for removing small molecular weight impurity and moisture; Described drying adopts spraying dry,
Described lime carbonating method is: in total extracting solution, add solid Ca(OH)
2, regulate pH value 10.0, stir 30 minutes, then pass into CO
2gas makes pH value reach till 7.0; Described activated carbon decolorizing method is: add and account for total extracting solution gross weight 2 ‰ gac, decolours 30 minutes; After described nanofiltration membrane is concentrated, inulin concentration is 20%.
The present invention is under the prerequisite keeping higher inulin extraction yield, technological process mainly extracts inulin with normal temperature milling process, inulin extraction process in early stage is simple and quick, do not use a large amount of hot water in technological process, therefore greatly reduce the energy consumption in inulin leaching process and water consumption, inulin extraction yield can reach more than 85% simultaneously, the inulin pure color obtained, purity >=92%, ash content≤0.25%, therefore overall economic efficiency is higher.
