Abstract
The invention discloses a method for separating an eggshell membrane from an eggshell. The separation principle of the method is characterized in that a separation agent hydrochloric acid is added to a raw material eggshell, and the eggshell is immersed in a heat insulation mode to make lime and keratins undergo a chemical change and reduce the combination force between the eggshell and the eggshell membrane, so the membrane can be separated from the eggshell under continuous stirring. The separation method provided by the invention has the advantages of simplicity, practicality, and high eggshell membrane recovery rate; and the separated eggshell membrane can be used as a raw material for natural cosmetics, and enables face skins to become tender and smooth.
Description
Technical field
The present invention relates to a kind of separation method of egg shell membrane, be specifically related to a kind of method of from eggshell, separating egg shell membrane.
Background technology
Egg shell membrane be a kind of be main body with protein, a kind of complex proteins that combines with mucopolysaccharide.Egg shell membrane is the hydrophilic semipermeable membrane, has good breathability, good moisture preserving ability and adsorption property.Along with the development of the rising of fowl egg output and egg product deep processing industry, the comprehensive utilization of eggshell become necessity and economically feasible.The method for distilling of existing albuminous coat is mainly machine and rolls, and this method is comparatively complicated, and destructible Calx shell and the original structure of egg shell membrane, and the response rate of albuminous coat is low simultaneously.
Summary of the invention
Goal of the invention: the present invention provides the method for from eggshell, separating egg shell membrane that a kind of technology is simple, the albuminous coat response rate is high in order to solve the deficiency of prior art.
The technical scheme that the present invention adopts: a kind of method of from eggshell, separating egg shell membrane is a raw material with the eggshell, and hydrochloric acid is separating medium, and its concrete steps comprise:
(1) gets the fresh eggshell of 5-8 part and put into glass container, add 12-15 part clear water, slowly be warming up to 40-45 ℃;
(2) under constantly stirring, add 1.5-2 part hydrochloric acid, insulation was soaked 1-1.5 hour;
(3) after insulation is soaked, the egg shell membrane emersion reclaims the buoyant egg shell membrane of the water surface, uses the clear water cyclic washing, removes residual acid, alkali, salt;
(4) the egg shell membrane moisture of cleaning is drained, sent into vacuum drying oven again and under 60-65 ℃, carry out drying, dry thing makes egg membrane powder after crushed.
As preferably, described eggshell is Ovum crusta Gallus domesticus, Ovum Anas domestica putamina or Ovum-crusta Anseris domestica.
As preferably, the described hydrochloric acid of above-mentioned steps (2) is concentrated hydrochloric acid.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: separation method provided by the invention is simple and practical, the egg shell membrane response rate is high, isolated albuminous coat can be used as the natural cosmetics raw material, can make skin of face become delicate, smooth.
The specific embodiment
Embodiment 1
Get 5 kilograms of fresh Ovum crusta Gallus domesticuss and put into glass container, add 12 kilograms of clear water, slowly be warming up to 40 ℃; Under constantly stirring, add 1.5 liters of concentrated hydrochloric acid, insulation was soaked 1 hour; After insulation was soaked, the egg shell membrane emersion reclaimed the buoyant egg shell membrane of the water surface, uses the clear water cyclic washing, removes residual acid, alkali, salt; The egg shell membrane moisture of cleaning is drained, sent into vacuum drying oven again and under 60 ℃, carry out drying, dry thing makes egg membrane powder after crushed.
Embodiment 2
Get 7 kilograms of fresh duck eggshells and put into glass container, add 13 kilograms of clear water, slowly be warming up to 42 ℃; Under constantly stirring, add 1.8 liters of concentrated hydrochloric acid, insulation was soaked 1.5 hours; After insulation was soaked, the egg shell membrane emersion reclaimed the buoyant egg shell membrane of the water surface, uses the clear water cyclic washing, removes residual acid, alkali, salt; The egg shell membrane moisture of cleaning is drained, sent into vacuum drying oven again and under 65 ℃, carry out drying, dry thing makes egg membrane powder after crushed.
Embodiment 3
Get 8 kilograms of fresh goose eggshells and put into glass container, add 15 kilograms of clear water, slowly be warming up to 45 ℃; Under constantly stirring, add 2 liters of concentrated hydrochloric acid, insulation was soaked 1.5 hours; After insulation was soaked, the egg shell membrane emersion reclaimed the buoyant egg shell membrane of the water surface, uses the clear water cyclic washing, removes residual acid, alkali, salt; The egg shell membrane moisture of cleaning is drained, sent into vacuum drying oven again and under 65 ℃, be carried out at dryly, dry thing makes egg membrane powder after crushed.
Claims (3)
1. a method of from eggshell, separating egg shell membrane is a raw material with the eggshell, and hydrochloric acid is separating medium, it is characterized in that: the concrete steps of from eggshell, separating egg shell membrane comprise:
(1) gets the fresh eggshell of 5-8 part and put into glass container, add 12-15 part clear water, slowly be warming up to 40-45 ℃;
(2) under constantly stirring, add 1.5-2 part hydrochloric acid, insulation was soaked 1-1.5 hour;
(3) after insulation is soaked, the egg shell membrane emersion reclaims the buoyant egg shell membrane of the water surface, uses the clear water cyclic washing, removes residual acid, alkali, salt;
(4) the egg shell membrane moisture of cleaning is drained, sent into vacuum drying oven again and under 60-65 ℃, carry out drying, dry thing makes egg membrane powder after crushed.
