Abstract
A bicarbonate process for preparing synanthrin from Jerusalem artichoke includes such steps as washing, shredding, leaching, removing impurities by bicarbonate method, desalting, decolouring and concentrating. Its advantages are high extraction efficiency and high yield (more than 95%, purity 98%) and quality of synanthrin.
Description
Technical field: the invention belongs to food processing field, particularly a kind of technology of from jerusalem artichoke, extracting synanthrin.
Background technology: jerusalem artichoke (Halianthus tuberosus) belongs to perennial feverfew, contains abundant inulin in the stem piece that it expands, formal name used at school synanthrin (inulin).Synanthrin is the polysaccharide that is formed by glucose end 7 to 30 fructose units of link.With synanthrin hydrolysis (two kinds of methods of usable acid hydrolysis and enzymolysis), can obtain fructose, oligofructose, these two kinds of sugar and synanthrin are popular in the world in recent years functional food, more and more are subject to people's attention because of they possess various nourishing functions.The relevant report that extracts synanthrin from jerusalem artichoke is a lot; as 1997 (1); one piece of article " the synanthrin hydrolysis prepares the fructose novel process " in the foodstuffs industry science and technology; mentioned and selected for use the AB-8 macroporous adsorbent resin to make discoloring agent purification fructose; the Zhu Hongji of chemical engineering institute of University Of Tianjin reports in " brief talking the production and the application of inulin " in " Shanghai chemical industry " the 2nd phase of calendar year 2001; behind the jerusalem artichoke extracting solution spent ion exchange resin desalination bleaching, concentrate drying gets inulin.Above Bao Dao extracting method, all there is deficiency from the height analysis of industrial application, in the extracting solution that adopts the hot water lixiviation process to obtain a large amount of impurity is arranged, these impurity are complicated and be colloidal state, as directly separating with absorption method, efficient is extremely low, filters very difficult, some non-sugar impurity also might be removed not exclusively, influence the purity of post-order process and product.
Summary of the invention: the purpose of this invention is to provide a kind of extraction yield height, product purity high and be suitable for suitability for industrialized production produce synanthrin double carbonation process technology with jerusalem artichoke.Purpose of the present invention realizes as follows:
Produce synanthrin double carbonation process technology with jerusalem artichoke, its its technological process comprises jerusalem artichoke cleaning chopping, leaching, double carbonation process removal of impurities, desalination bleaching, concentrates;
The temperature of above-mentioned leaching process is 75-80 ℃, and the time is 30 minutes-90 minutes;
Above-mentioned double carbonation process removal of impurities is to add milk of lime in leach liquor, adjusts pH value 12-13, feeds CO again
2Gas makes pH value reduce to 11, and clear liquid is heated to 90-100 ℃ behind the filtration under diminished pressure, feeds CO again
2Make pH value reduce to 8, under heating condition, filter impurity elimination;
Above-mentioned desalination bleaching is to adopt extracting solution through the ion exchange resin desalination bleaching;
Above-mentioned ion exchange resin is to adopt strong acid, highly basic and weak-acid ion exchange resin to replace desalination bleaching;
Above-mentioned concentration process is to adopt concentrating under reduced pressure, is concentrated into solid substance 〉=75% (weight).
The present invention is owing to adopted double carbonation process that extracting solution is handled, amounts of protein, jelly are removed in advance, alleviated the pressure of resin desalination, decolouring greatly, the extraction efficiency and the yield of product have been put forward, the purity and the quality of product have been ensured simultaneously, after tested, extraction yield is greater than 95%, synanthrin purity 〉=98% (weight).
Embodiment:
1. jerusalem artichoke is cleaned chopping:
At first select jerusalem artichoke, the part of rotting, go bad is machined away, clean up post-treatment or filament, place in the stainless steel vessel.
2. leach: add entry in the container, it is good that the weight ratio of the water yield and jerusalem artichoke is controlled at 1-2, is heated to 75-80 ℃, be incubated squeeze the juice after 60 minutes extracting solution.
3. double carbonation process impurity elimination:
(1) in extracting solution, adds milk of lime, stablize 12.5 to pH value;
(2) feed CO
2Gas makes pH value reduce to 11;
(3) filtration under diminished pressure is removed solid substance;
(4) filter the back clear liquid and be heated to 95 ℃, feed CO once more
2, make its pH value reduce to 8, filter once more clear liquid;
4. desalination bleaching:
Above-mentioned clear liquid successively by strongly-acid, strong basicity and weak-acid ion exchange resin, is obtained pure, colourless extracting solution;
5. concentrate: adopt vacuum concentration to obtain the synanthrin product that dry matter content does not wait,, then it can be concentrated into dry matter content and reach 15% (W) and get final product as further producing fructose.
