Description
Technical field
The present invention relates to the preparation method of collagen protein, more particularly to a kind of preparation method of edible pigskin gelatin.
Background technology
The application of gelatin is extremely wide, can be divided into edible Gelatinum oxhide, pharmaceutical glue, photosensitive gelatin and industry by purposes bright
The big species of glue four, wherein edible Gelatinum oxhide (Gelatin) are the hydrolyzate of collagen, are a kind of fat free high protein, and are not contained
Cholesterol, is a kind of food thickening agent of native trophism.
The preparation method of traditional gelatin, is gelatin thin liquid first to be filtered, concentrated, being freezed, is cut into slices and be finally dried, such as：《Cause
The friend of richness》3rd 22-22 page of phase in 1997, document description is first congealed, is dried after flaking.Due to the drying of lamellar gelatin, connect
Tactile limited area, and each orientation has certain temperature difference due to drying equipment, causes slow drying speed and uneven, causes
Granularity after crushing is also uneven.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of fast drying and even-grained edible pigskin gelatin
Preparation method.
Technical problem solved by the invention is employed the following technical solutions and is achieved：
A kind of preparation method of edible pigskin gelatin, it is characterised in that comprise the following steps：
1）The pigskin gelatin liquid for boiling is diluted to into the pigskin gelatin thin liquid of 1 ~ 3wt%, is filtered, then filtrate is passed through into ion
Exchanger resin remove impurity, then will transmit through liquid and is concentrated by ultrafiltration to 25 ~ 30% concentrated solution；
2）Paste is frozen into after concentrated solution is sterilized, it is 1 ~ 3mm to be squeezed into external diameter, and internal diameter is the hollow strip of 0.5 ~ 2mm
Thing；
3）The hollow bar of drying under the conditions of temperature is for 35 ~ 45 DEG C, moisture is down to 8 ~ 10%, is then crushed.
It is preferred that, step 1）Kieselguhr or cottonseed cake or activated carbon are adopted in the filtration as filter medium.
It is preferred that, step 1）The ion exchange resin is the columns in series of anion and cation exchange resin.
It is preferred that, step 2）The sterilising temp is 135-145 DEG C.
It is preferred that, the step 2）The internal diameter of hollow bar is 1 ~ 2mm.
It is preferred that, the step 2）Hollow bar carries crackle.
It is preferred that, step 3）The drying is fourdrinier wire drying.
It is preferred that, step 3）The temperature is 40 ~ 45 DEG C.
It is preferred that, also include step 3）Products obtained therefrom is mixed, is packed.
The Advantageous Effects of the present invention：
1st, pigskin gelatin thin liquid of the present invention first passes around filtration, filters macromolecular particle, then through ion exchange resin mistake
Filter the medium grain impurity such as salinity, metal ion, acid ion, chromogen, reconcentration；Concentrated solution after concentrated is quick
Freezing, is squeezed into hollow bar, for hollow bar is with respect to tablet, in dry run by the paste gelatin after freezing
In, increase the surface area with hot air impingement, and the inside and outside of hollow bar has steam so that hollow bar each
Position touches steam, and the flowing velocity and concentration of inside and outside steam is different, causes inside and outside steam to have certain pressure reduction, because
Have pressure reduction, steam will from pressure it is big where to pressure it is little where flow, have part steam to pass through thin hollow strip
Thing, so as to form certain hole on hollow bar, there is hole, just further increases contact area so that hollow
The moisture evaporation of bar surface is fast so that rate of drying is fast, and after testing, more than 98% in 8 ~ 10 mesh, other indexs for products obtained therefrom
Comply fully with the related request of edible Gelatinum oxhide.
2nd, the paste pigskin gelatin after freezing is squeezed into into bar hollow and with crackle, in dry run, enters one
Step increases contact surface area of the bar with steam, and drying is more thorough.
3rd, hollow bar is dried with Fourdrinier type drying machine, because hot-air can be with guipure forward in Fourdrinier type drying machine
Motion is blown with blower fan, fluctuation and stable thermal current up and down is formed, by the drive of air-flow, hollow bar rate of drying
Faster.
