(2) liquid temp to be filmed drops to 40-70 ℃, regulates pH5.0-9.0, adds linking agent, the insulation 5min-2h that stirs,
(3) under the room temperature condition film forming liquid is filtered drying and forming-film.
Preparation method's one optimal technical scheme according to a kind of blend film of the present invention: the preparation method of described peptide of tussur silk is: getting concentration is the Powdered tussah silk fibroin of 10mg/mL, add a certain amount of damping fluid, regulate pH to 9, the Sumizyme MP that adds 8% (w/w) again, in 50 ℃ of water-baths behind the hydrolysis 4h, 85 ℃ of centrifugal 10min of enzyme 15min, 6000rpm that go out, get supernatant liquor, promptly get peptide of tussur silk through lyophilize.
Preparation method's one optimal technical scheme according to a kind of blend film of the present invention: the preparation method of described Powdered tussah silk fibroin is: the sodium carbonate solution of the employing of the cocoon shell after the removal of impurities 0.5% is carried out secondary degumming, fibrous fibroin 1-10g after will coming unstuck, divide and place the constantly nitrocalcite of the molten state of heating of 20-300g for 10 times, to all dissolvings, it is the 7000-14000 dialysis tubing that molecular weight is blocked in employing, with tap water, deionized water dialysis, dialysis promptly gets Powdered tussah silk fibroin after finishing in succession.
Preparation method's one optimal technical scheme according to a kind of blend film of the present invention: the method for described drying at room temperature Cheng Mo is: draw 2mL film forming liquid on plastic carrier, be coated with into the uniform film of distribution, remove 20min-4h in the air dry oven that bubble is placed on 20-60 ℃, take off film after to be dried.
Beneficial effect of the present invention is:
1, raw material of the present invention is a tussah piques shell, for improving its value, rationally utilizes its nutritive value that an effective way is provided;
2, technology of the present invention is reasonable, simple possible, and cost is low;
3, the peptide of tussur silk edible film has good ductility, mechanicalness, and transparency is better;
4, this product safety is reliable, and not only having can be used as wrapping material, to use but also can be used as nutritive substance edible, has a extensive future.
