(57) Abstract: Starch-based fluffy particles and a preparation method therefor and 
an application thereof, relating to the technical field of hemostatic materials. The 
preparation method for the starch-based fluffy particles comprises the following 
Steps: (1) adding water into starch or modified starch for gelatinization to obtain 
starch paste; (2) adding the starch paste into an organic solvent, performing stir
ring, standing and centrifugation, and collecting a precipitate; and (3) perform
ing freeze drying, crushing and sieving on the precipitate in sequence to prepare 
the starch-based fluffy particles. The starch-based fluffy particles are porous and 
fluffy, are large in particle gap, have excellent water absorption speed, water ab
sorption rate and degradation rate, and can achieve the purpose of rapid and effi
cient hemostasis; and the starch-based fluffy particles are free of addition of com
ponents such as a dispersing agent, an emulsifying agent, or a cross-linking agent 
-i 2 and have the characteristics of safety and reliability, so that the hemostatic require
ment of an in-vivo environment is also satisfied.
