Embodiment 2
[0049] The influence of embodiment 2 ginger juice on composite film chroma
[0050] Methods as below:
[0051] 1) Peel and smash fresh ginger, filter through a filter cloth to obtain coarse ginger juice, and pour out the supernatant;
[0052] 2) As shown in Table 1, according to the volume ratio, take 0ml, 5ml, 7ml and 9ml of ginger juice and 20ml, 15ml, 13ml and 11ml of deionized water to make different proportions of material I (the total volume is 20ml, and the mass is about 20g);
[0053] 3) Mix 20 mL of material I, 1.0 g of glycerol, 0.2 g of sodium carboxymethyl cellulose, 0.5 g of ethanol, and 2.0 g of potato starch according to the mass to obtain material II;
[0054] 4) Put the material II in a magnetic stirrer to gelatinize for 1 hour to obtain the material III;
[0055] 5) Make the material III pass through a 40-60 mesh sieve to remove the upper layer of sticky matter to obtain a clarified starch paste, that is, the material IV, and distribute it evenly in a plate...
Embodiment 3

[0062] Methods as below:
[0063] 1) Peel and smash fresh ginger, filter through a filter cloth to obtain coarse ginger juice, and pour out the supernatant;
[0064] 2) As shown in Table 3, according to the mass ratio, take glycerol and deionized water to make different proportions of material I;
[0065] Table 3 The ratio of glycerol to deionized water
[0066] Glycerol (g) 0.0000 0.5000 1.0000 1.5000 Deionized water (g) 20.00 20.00 20.00 20.00
[0067] 3) Mix 9ml ginger juice, 0.2g sodium carboxymethylcellulose, 0.5g ethanol, and 2.0g potato starch to obtain material II;
[0068] 4) Mixing material I and material II to obtain compound starch milk (material III);
[0069] 5) Put material III in a magnetic stirrer to gelatinize for 1 hour to obtain material IV;
[0070] 6) Make the material IV pass through a 40-60 mesh sieve to remove the upper layer of sticky matter...
Embodiment 4
[0076] Example 4 Effect of sodium carboxymethylcellulose (CMC) on the mechanical properties of composite membranes.
[0077] Methods as below:
[0078] 1) Peel and smash fresh ginger, filter through a filter cloth to obtain coarse ginger juice, and pour out the supernatant;
[0079] 2) As shown in Table 5, according to the mass ratio, take sodium carboxymethylcellulose (CMC) and deionized water to make solutions of different proportions (material I);
[0080] Table 5 Ratio of sodium carboxymethylcellulose (CMC) to deionized water
[0081] CMC(g) 0.2000 0.3000 0.4000 Deionized water (g) 20.00 20.00 20.00
[0082] 3) Mix 9ml of ginger juice, 1.0g of glycerol, 0.5g of ethanol, and 2.0g of potato starch to obtain material II;
[0083] 4) Mixing material I and material II to obtain compound starch milk (material III);
[0084] 5) Put material III in a magnetic stirrer to gelatinize for 1 hour to obtain material IV;
[0085] 6) Make the material IV pass...
