Embodiment Construction
[0019] A kind of preparation method of novel nutritional rehabilitation type skin care mask:
[0020]1. Crush the cocoon shell of the dried colored cocoon into 2mm-sized pieces, then measure distilled water 50 times the mass of the cocoon shell raw material, soak the raw material fragments in the aqueous solution, and make it fully swell for 40 minutes, and then Boil under normal pressure to elute the sericin in the raw material into the solution and hydrolyze to a certain extent. When the solution is concentrated to 1 / 6 of the original volume, stop heating and cool to room temperature. Add 2.0% mass of cocoon capsid neutral protease to the solution for enzymolysis, the enzymolysis temperature is 25°C, the pH value is 7.0, and the enzymolysis is continued for 200 minutes, so that the sericin protein in the solution is hydrolyzed to an average molecular weight of 10000-20000Da active sericin. Then the solution was heated to 100°C for 25 minutes to inactivate the enzyme activi...
