[0026] The preparation method of starch raw material is:
[0027] (1) Take starch and add acetic acid-sodium acetate buffer solution with a pH of 4.5 according to the mass ratio of 3~5:40~60, stir and mix at 90~95°C for 50~60min, cool to obtain the cooled product, take pullulanase and press Mass ratio 1~3: 100~150, add cooling substance, incubate at 45~55°C for 1~3h, inactivate enzyme, centrifuge, take precipitate, wash with absolute ethanol, dry to obtain dried substance;
[0028] (2) Take the dry matter and add deionized water according to the mass ratio of 3~5:10~15, stir and mix at 30~40°C for 20~30min, adjust the pH to 8~8.5, add 3~9% acetic anhydride of dry matter , stir and mix at 30-40°C for 1-3 hours, adjust the pH to 6-7, centrifuge, take the precipitate a and dry it, crush it through a 200-mesh sieve, collect the sieved particles, and obtain the starch raw material.
[0029]The alcohol active agent is as follows: in parts by mass, 5-10 parts of n-octanol, 3-5 parts...

[0040] The starch is: take plantain taro starch and mix it with corn starch in a mass ratio of 5:2.
[0041] The preparation method of starch raw material is:
[0042] (1) Take starch and add acetic acid-sodium acetate buffer solution with a pH of 4.5 at a mass ratio of 3:40, stir and mix at 90°C for 50 minutes, cool to obtain a cooling product, take pullulanase and add it to the cooling product at a mass ratio of 1:100 , incubate at 45°C for 1 h, inactivate the enzyme, centrifuge, take the precipitate, wash with absolute ethanol, and dry to obtain a dried product;
[0043] (2) Take the dry matter and add deionized water at a mass ratio of 3:10, stir and mix at 30°C for 20 minutes, adjust the pH to 8, add 3% acetic anhydride of the dry matter, stir and mix at 30°C for 1 hour, and adjust the pH to 6 , centrifuge, take the precipitate a and dry it, crush it through a 200-mesh sieve, collect the sieved particles, and obtain the starch raw material.
