[0105] b, 3 g erythritol, 0.5 g citric acid, 0.33 g sodium citrate and 0.84 g blueberry flavor are added to glue liquid 1-glue liquid 3 respectively, and stirred and dissolved at room temperature to obtain glue liquid 4, glue liquid 5 and glue liquid 6;
[0106] c, 30 mL of 10000 U / mL superoxide dismutase solution, 1 g silkworm pupa protein peptide, 0.16 g blueberry anthocyanin and 2.4 g trehalose are added to glue liquid 4-glue liquid 6 respectively, and stirred and dissolved at room temperature to obtain slurry 1, slurry 2 and slurry 3;
[0107] d, the slurry 1-slurry 3 is respectively put into a vacuum defoaming container machine for defoaming treatment (the defoaming treatment is divided into three stages, the defoaming time of the first stage is 60 s, the defoaming rotation speed is 1000 r / min, and the vacuum degree is 101.7 kPa; the defoaming time of the second stage is 100 s, the defoaming rotation speed is 1600 r / min, and the vacuum degree is 0.5 kPa; the defoaming time of the third stage is 80 s, the defoaming rotation speed is 1800 r / min, and the vacuum degree is 0.5 kPa);
[0108] e, the defoamed slurry 1-slurry 3 is respectively transported to a mouth dissolving film coating machine, and coated and formed at 60°C (coating speed is 15 mm / s, coating thickness is 0.6 mm±0.1) to obtain the oral dissolving film 14 (1.667 g glycerol), the oral dissolving film 15 (3 g glycerol) and the oral dissolving film 16 (3.334 g glycerol).
[0109] The oral dissolving film containing superoxide dismutase prepared by the preparation of the comparative example 2 and the comparative example 3 is detected, and the detection results are shown in table 7.
[0110] Table 7
[0111]
[0112] As shown in table 7, when the film forming material is hydroxypropyl methyl cellulose-gelatin, the SOD enzyme activity is very low, and the addition of gelatin will interfere with the enzyme activity detection; when the film forming material is hydroxypropyl methyl cellulose-polyvinyl alcohol, the oral dissolving film dissolves slowly. When 1.667 g glycerol is added, the oral dissolving film has low folding resistance and is easy to break during transportation; when 3 g or 3.334 g glycerol is added, the surface of the oral dissolving film is too sticky, which affects the sub-packaging and the taking experience.
[0113] Comparative example 4
[0114] The same operation steps as in the preparation of oral fast dissolving film 4 in Example 3, except that the equal volume of superoxide dismutase solution in step c is replaced by water to obtain oral fast dissolving film 17.
[0115] Comparative Example 5
[0116] The same operation steps as in Example 1, except that the amount of trehalose added is changed to 0.6 g to obtain oral fast dissolving film 18; the amount of trehalose added is changed to 1.2 g to obtain oral fast dissolving film 19; and the amount of trehalose added is changed to 3 g to obtain oral fast dissolving film 20.
[0117] The oral fast dissolving films prepared in Comparative Example 4 and Comparative Example 5 are detected, and the detection results are shown in Table 8.

[0119]
[0120] In the present application, the performance detection method of the oral fast dissolving film is:
[0121] (1) The folding resistance detection method: 5 pieces of 2x2 cm 2 size oral fast dissolving films are taken, and the middle position of the oral dissolving film is repeatedly folded by 180° until it is broken, and the average folding number is recorded;
[0122] (2) The disintegration time detection method:
[0123] In vivo test: 50 volunteers aged 25 years old (25 men and 25 women) use clean water to gargle, and then place 2x2 cm 2 size oral fast dissolving films on the tongue surface, and at the same time, the time is counted. The volunteers pause the timing when they cannot feel the foreign body without chewing and actively swallowing, and the time is recorded and averaged;
[0124] In vitro test: 5 pieces of 2x2 cm 2 oral fast dissolving films are taken and placed in beakers containing 50 mL of 37℃ water, vortexed, and the time for the oral fast dissolving film to completely dissolve in water is observed and recorded by naked eye, and the average value is taken;
[0125] (3) The SOD enzyme activity detection method: 5 pieces of 3x3 cm 2 size oral dissolving films are taken, and 1 mL of water is used to dissolve them, and then the SOD enzyme activity is detected according to GB / T5009.171-2003 "Determination of superoxide dismutase (SOD) activity in health food", and the average SOD enzyme activity is calculated.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
