Embodiment 1
[0032] The edible and soluble composite film packaging material is composed of starch, polysaccharide, protein and alcohols. In this embodiment, the starch is potato starch or corn starch or wheat starch, and the polysaccharide is xanthan gum sugar or chitosan or glucomannan or seaweed polysaccharide.
[0033] The preparation method comprises the following process steps:
[0034] A, material preparation: take starch, polysaccharide, protein and alcohols and put them into containers respectively, and set them aside;
[0035] B. Modification: Add maleic anhydride or acetic anhydride or sodium trimetaphosphate with a dosage of 15% into containers containing starch and polysaccharides respectively, and carry out general modification, that is, esterification, to starch and polysaccharides. Sex time 2 hours, spare;
[0036] C. Glue making:
[0037] The preparation of nail nails, said nail nails include the following components and weight percentages, the total amount is 100%, the...
Embodiment 2
[0046] The present embodiment is basically the same as Example 1, the difference being: the preparation of the nail gel: get 250 grams of the modified starch, 220 grams of the modified polysaccharide, 80 grams of collagen, 75 grams of zein, casein 75 grams of protein, 150 grams of glycerin, 150 grams of sorbitol;
[0047] The preparation of the second glue: get 250 grams of the polysaccharide, 250 grams of sodium carboxymethylcellulose, 100 grams of collagen, 100 grams of casein, 150 grams of glycerin, and 150 grams of sorbitol.
Embodiment 3
[0049] The present embodiment is basically the same as Example 1, the difference being: the preparation of the nail gel: get 220 grams of the modified starch, 250 grams of the modified polysaccharide, 75 grams of collagen, 80 grams of zein, casein 80 grams of protein, 175 grams of glycerin, 120 grams of sorbitol;
[0050] The preparation of the second glue: get 150 grams of the polysaccharide, 300 grams of sodium carboxymethylcellulose, 75 grams of collagen, 75 grams of casein, 200 grams of glycerin, and 200 grams of sorbitol.
