Apparatus for the production of the protein skin of antarctica fish

摘要

An apparatus for the production of the protein skin of antarctica fish (chionodraco rastrospinosus), comprising a squeeze-off - and cleaning device (10) for thawing of the frozen carp skin (esox lucius) during 12 hours at 7°C, after which the carp skin with cleaning water at a temperature of about 10°C. is cleaned; a skin slags, the processor (15), which is connected with the squeeze-off - and cleaning device (10) for the preparation of the defatted skin slag is connected to the invention, wherein after the cleaning of the skin this skin in the upstream squeeze-off - and cleaning device (10) with a incidences of mass is beaten to a skin, and this skin mass then is added to water, wherein the skin mass with a colloid mill (16) is ground into a skin slag, wherein the skin slag is centrifuged, and wherein the upper layer of fat of the skin slag is removed in order to obtain the degreased skin slag; an ultrasonic generator (20), which is connected to the skin slags, the processor (15) is connected, which receives the degreased skin slag, after which the structure of the skin proteins of the slag with the ultrasonic treatment with a power of 800 w and a frequency of 25 khz during 10 minutes is changed; a composite dilute solutions ezu sensor (25), which is connected to the ultrasonic generator (20) is connected, wherein the composite protease the with the ultrasonic generator (20) is added to processed slag, wherein the composite protease a composition of alkalin - protease and neutral protease is, the with a mass ratio of 1: 1 are mixed, and wherein the slag at a temperature of 50°C. and having a ph - value of 7,5 during 0,5 hours was digested; a collector (30), the dilute solutions with the composite element transducer (25) is connected, which receives from the zugeber the slag, after which the slag at a temperature of 95°C. leaves and then cooled to room temperature, wherein a 4000g - centrifuging takes place during 10 minutes and then a projection on a top layer of the slag is collected, wherein the molecular weight of the protein skin in the supernatant between 2600 daltons - 33000 daltons; a two-stage filter (35), of the connected to the collector (30) is connected to the supernatant from the collector (30) for a two-stage ultrafiltration process is to be received, whereby in a first step, the protrusion with a ceramic ultrafilter (36) having a pore size of 0,5 μm and is filtered after filtering the proteins having a molecular weight of less than 10000 dalton of the polypeptides are separated, wherein then further a ceramic filter (37) having a pore size of 2 μm is used, after which the proteins having a molecular weight of from 8000 daltons - 10000 dalton are separated, in order to 85 g of the skin protein having a molecular weight of from 8000 daltons - 10000 dalton to obtain.
