specific Embodiment approach 1
[0028] A preparation method for mixing nano starch deodorant, comprising the steps of:
[0029] (1) Take corn amylose and glutinous rice amylopectin according to the ratio of 1:1, and dissolve them in dimethyl sulfoxide (DMSO), wherein the total concentration of corn amylose and glutinous rice amylopectin is required to be 2 %, stirring in a boiling water bath for 2 hours; then slowly drop into 200mL of ethanol to obtain precipitate A;
[0030] (2) Take the precipitate A and dry it at 40°C for 2 hours to obtain corn amylose and glutinous rice amylopectin powder; add the obtained corn amylose and glutinous rice amylopectin powder to 10ml of water, and heat in a boiling water bath Stir for 60 minutes to fully gelatinize; add 40 mL of ethanol dropwise, stir at 600 rpm for 4 hours, and centrifuge to obtain mixed nanoparticles B; then wash with ethanol for 3 times, and freeze-dry;
[0031] (3) Ultrasonic washing of the resulting mixed nanoparticle B for 30 minutes to obtain a mixe...

[0033] A preparation method for mixing nano starch deodorant, comprising the steps of:
[0034] (1) Weigh potato amylose and corn amylopectin according to a ratio of 1:5 and dissolve them in dimethyl sulfoxide (DMSO), wherein the total concentration of potato amylose and corn amylopectin is required to be 5 %, stirred in boiling water bath for 5h; then slowly drop into 500mL of ethanol to obtain precipitate A;
[0035] (2) Take the precipitate A and dry it at 40°C for 2 hours to obtain potato amylose and corn amylopectin powders; add the obtained potato amylose and corn amylopectin powders to 10ml of water and heat in a boiling water bath Stir for 90 minutes to fully gelatinize; add 200 mL of ethanol dropwise, stir at 600 rpm for 4 hours, and centrifuge to obtain mixed nanoparticles B; then wash with ethanol for 3 times, and freeze-dry;
[0036] (3) Ultrasonic washing of the resulting mixed nanoparticle B for 30 minutes to obtain a mixed nano-starch deodorant;

specific Embodiment approach 3
[0038] A preparation method for mixing nano starch deodorant, comprising the steps of:
[0039] (1) Take pea amylose and potato amylopectin according to the ratio of 5:1, and dissolve them in dimethyl sulfoxide (DMSO), wherein the total concentration of pea amylose and potato amylopectin is required to be 5 %, stirred in a boiling water bath for 5 hours; then slowly drop into 800mL of ethanol to obtain precipitate A;
[0040] (2) Take the precipitate A and dry it at 40°C for 2 hours to obtain pea amylose and potato amylopectin powders; add the obtained pea amylose and potato amylopectin powders to 10ml of water and heat in a boiling water bath Stir for 90 minutes to fully gelatinize; add 200 mL of ethanol dropwise, stir at 600 rpm for 4 hours, and centrifuge to obtain mixed nanoparticles B; then wash with ethanol for 3 times, and freeze-dry;
[0041] (3) Ultrasonic washing of the resulting mixed nanoparticle B for 30 minutes to obtain a mixed nano-starch deodorant;
