The production method of gold ear particle
Technical field
The invention belongs to edible mushroom deep process technology field, be specifically related to the production method of golden ear particle.
Background technology
The gold ear (
Tremella aurantiallba) be the precious edible mushroom of a kind of medicine-food two-purpose, be rich in multiple nutritional components, especially contain more rich β one carrotene, riboflavin and Jin Er macromolecular polysaccharide, other edible mushrooms are incomparable.At present main eating method is that long-time stewing boiled, and is made into golden ear custard after golden ear was cleaned, and the glutinous profit of delicate mouthfeel is very popular.Aspect deep processing, mainly to extract golden fungus polysaccharides, will be applied to healthy food material after the golden ear extract drying, but when using as instant product, because the golden fungus polysaccharides molecular weight is bigger, cause instant capacity relatively poor.At this problem, the invention provides a kind of golden ear particulate manufacturing method, improved the instant capacity of golden ear particle greatly.
Summary of the invention
It is bigger to The present invention be directed to the golden fungus polysaccharides molecular weight, viscosity be difficult for to extract is filtered greatly, dissolubility is relatively poor is difficult for instant technical problem, provides a kind of production method of golden ear particle, the golden ear particle that utilizes this method to produce, can be used as a kind of instant golden ear particle, reconstituting with boiling water is edible.The present invention also provides the golden ear particle of producing with the inventive method.
For achieving the above object, the production method of golden ear particle of the present invention may further comprise the steps:
(1) pretreatment of raw material: fresh golden ear is cleaned up, pelletizing or with golden ear dry product with 45 ℃~55 ℃ bubble after, clean up, pelletizing is that 1:3~5 ratios add deionized water and grind the De Jiner slurry with the mass ratio of Jin Er and water;
(2) enzyme is handled: add cellulase and pectase in golden ear slurry, be under 40~50 ℃ of conditions in temperature, stir insulation 1~2 hour, the golden ear slurry of enzyme after handling, the addition of cellulase is the 0.3-0.5% of golden ear slurry quality, and the addition of pectase is 0.5~0.7% of golden ear slurry quality;
(3) extraction is handled: the deionized water that the golden ear slurry quality after the adding consumption is the enzyme processing in the golden ear slurry after the described enzyme processing of step (2) is 20 times, be heated to 95~100 ℃, and under agitation keep getting in 1 hour 30 minutes~2 hours solution;
(4) centrifugation: the described solution of step (3) is centrifugal through decanter type tripod pendulum type batch centrifugal, cloth filter formula tripod pendulum type batch centrifugal and tube centrifuge successively, get supernatant and precipitation; The centrifugal speed of described decanter type tripod pendulum type batch centrifugal and cloth filter formula tripod pendulum type batch centrifugal is 3000 rev/mins~4000 rev/mins
,When centrifugal with cloth filter formula tripod pendulum type batch centrifugal, adopt 2~3 layers of gauze as filter cloth, the centrifugal speed of tube centrifuge is 30000 rev/mins~35000 rev/mins;
(5) vacuum concentrates: the described supernatant vacuum of step (4) is concentrated into 1/3 volume, and the De Jiner concentrate, the condition that vacuum concentrates is: vacuum is that 0.045~0.040MPa, temperature are 70~76 ℃ in the vaporization chamber;
(6) compatibility: the golden ear concentrate that step (5) is obtained is heated to 55~60 ℃, and with golden ear concentrate: dextrin: the mass ratio of glucose is the ratio of 15:1.5:1, stirs to add dextrin and glucose gets mixed liquor;
(7) drying: the mixed liquor spray-drying that step (6) is obtained is the De Jiner particle.
The precipitation repeating step (3) that step (4) can also be obtained and the operation of (4) obtain the secondary supernatant, and merge secondary supernatant and the described supernatant of step (4) to such an extent that merge supernatant, will merge supernatant set by step (5) to step (7) operate the De Jiner particle.
Can also after (7) spray-drying obtains golden ear particle, described golden ear particle be packed, vacuum seal, the material of bag can be the clad aluminum foil bag, the specification of bag can be the 10g/ bag.
Production method with above-mentioned golden ear particle prepares golden ear particle of the present invention.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts complex enzyme to handle golden ear, has increased the extraction effect of golden ear active ingredient; Extract adopts three different modes centrifugal, under the condition of not adding any filter aid, makes solid-liquid obtain fine separation; Gold ear extract main component is golden fungus polysaccharides, because the golden fungus polysaccharides molecular weight is bigger, after the drying and crushing, dissolubility is relatively poor, the inventive method is added dextrin and the glucose of suitable proportion before golden ear concentrate drying, form one with golden fungus polysaccharides, carry out spray-drying, this gold ear product is in hot water, little molecule dextrin, glucose at first dissolves, make the relatively poor polysaccharide body of dissolubility form cavity effect and accelerate dissolution, thereby the golden ear particle of the present invention's production, good dispersion had, but instant, instant, delicate mouthfeel is lubricious, is a kind of nutritional health food.Technology operation of the present invention is simple.
