Description
Technical field
The present invention relates to chitosan packing konjak composition and preparation technology thereof and purposes.
Background technology
Konjaku is used as suspension agent, emulsifying agent, stablizer, thickening material, weighting agent, quality improver etc. in foodstuffs industry, with the konjaku powder is that main raw material can be produced various konjakus (bionical) low-heat heath food, and this is the foods with high dietary fiber of a class international popular.Konjaku also is applied to pharmaceutical industry except that being mainly used in food.High-purity konjac polysaccharide has characteristics such as not producing heat, strong suction, desirable food fiber, in the interpolation and the release of medicine, helps the control body weight, food fibre, get rid of heavy metal ion, enzyme fixed bed, control blood fat, improve immunizing power, diabetes, aspects such as crystalline material have unique function.
The chitosan chemical name is β-1, and 4-2-amino-2-deoxidation-D-dextran claims chitosan, chitin, chitosan, soluble chitin etc. again, is the derivative that chitin obtains behind the concentrated base deacetylation, and is water insoluble, but be dissolved in the diluted acid.Chitosan is widely used in pharmaceutics (drug release at present, hemodialysis), medical science (medical textile, operating sutures, artificial blood vessel, the health auxiliary material, medical parting material), the daily use chemicals makeup, food (healthcare products, foodstuff additive, fodder additives etc.), metal-chelating and sewage disposal (flocculation agent etc.).Chitin and chitosan (Chinese marine industry standard SC/T3403-2004) are divided into low degree of deacetylation (＜75.0%) according to the degree of deacetylation size; middle degree of deacetylation (75.0-89.0%); high degree of deacetylation (90.0-95.0%), superelevation degree of deacetylation (＞95.0%).
The method one of the edible konjaku of people is that konjaku is made all kinds of finished products at present, as konjak food (preparation methods of number of patent application 93112615.0 shrimp meat-like konjak products), konjak noodle (number of patent application 02111265.7 konjak noodle and working method thereof), taro vermicelli (number of patent application 98113677.X instant vermicelli made from bean starch containing konjak) etc., another kind method is exactly directly to use Rhizoma amorphophalli powder, make capsule or use the Rhizoma amorphophalli powder bath, fruit juice etc. are drunk (ZL99117437.2 konjak solid beverage, number of patent application 200510010731.5 soak type konjak edible fiber food with primary taste, number of patent application 200810236691.X konjak dietary fiber effervescent tablet and preparation method thereof), but at the above konjaku that is used to make solid beverage, no matter be directly to use konjaku also to be to use konjaku and some edible gum bonded konjakus, dissolving fast can make the beverage quick-gelatinizing of these konjak solid beverage pulvis punching out in hot water, and drinking way not too meets the people's conventional requirement.
Summary of the invention
Problem to be solved by this invention provide a kind of in hot water insoluble or dissolved konjac compositions at a slow speed, said composition has most of good characteristics of konjaku itself, and use range advantage widely.
Technical scheme provided by the invention is: a kind of chitosan packing konjak composition, and be encapsulated in the Rhizoma amorphophalli powder particle surface by chitosan and constitute, wherein the mass ratio of chitosan and konjaku is 0.5: 99.5～5: 95.
Above-mentioned Rhizoma amorphophalli powder is konjaku powder, Rhizoma amorphophalli micropowder, konjaku purifying powder or konjak gum, and the chitosan degree of deacetylation is not less than 75%.
The particle diameter of above-mentioned Rhizoma amorphophalli powder is 75～550 μ m or is lower than 120 μ m.Flotation property when being used for beverage for the guarantee konjaku, the konjaku grain diameter that is proposed to be used in beverage is less than 120 μ m.Need to select in addition the different konjaku of particle diameter (as the time particle diameter can at 75～550 μ m) when being used for other purposes as abrasive particle.
The present invention also provides the method for making of above-mentioned chitosan packing konjak composition: chitosan imbedded liquid is made in chitosan and acid and alcohol; At 15 ℃ to 60 ℃, Rhizoma amorphophalli powder added in the chitosan imbedded liquid stir, after mixture mixes, in reaction system, add the alkali neutralization, the centrifugation solid substance is chitosan packing konjak composition behind the cleaning-drying.
The acid that the chitosan imbedded liquid of above-mentioned preparation uses is formic acid, acetate, lactic acid, phenylformic acid, vinylformic acid, Mono Chloro Acetic Acid, hydrochloric acid, citric acid or tartrate, wherein adding the amount of acid and the amount ratio of chitosan is 1～9: 1, and described ratio be the ratio of glucosamine residue weight in sour chemical magnitude and the chitosan.
More than 30%, described alcohol is ethanol, methyl alcohol or Virahol to pure content in volume percent in the above-mentioned chitosan imbedded liquid.
Above-mentioned konjaku adds time of stirring in the chitosan imbedded solution more than 30 minutes.
Among the present invention and used alkali be sodium hydroxide, potassium hydroxide, lithium hydroxide, calcium hydroxide, yellow soda ash or salt of wormwood, the add-on of alkali is counted 0.6～5 times that the used acid of dissolving chitosan is measured by the ratio of amount of substance, and the temperature in the N-process is at 15 ℃ to 60 ℃.
The present invention not only composition has most of good characteristics of konjaku itself, and insoluble or dissolving at a slow speed in hot water, and use range is extensive.Chitosan packing konjak composition of the present invention is used to prepare the konjak solid beverage raw material or as the additive of makeup etc.
