Process for preparing a biodegradable plastic composition
The present invention relates to plastic composition comprising at least one polyester, biological entities having a polyester-degrading activity and at least an anti-acid filler, wherein the biological entities represent less than 11% by weight, based on the total weight of the plastic composition, and uses thereof for manufacturing biodegradable plastic articles.
Starch-Based Fluffy Particle, Preparation Method and Use Thereof
The present disclosure discloses a starch-based fluffy particle, a preparation method and use thereof. The preparation method of the starch-based fluffy particle comprises the following steps of: (1) adding water into starch or modified starch for gelatinization to obtain a starch paste; (2) adding the starch paste into a polar organic solvent, stirring, standing and centrifuging to collecting a precipitate; and (3) freeze-drying, crushing and sieving the precipitate in sequence to prepare the starch-based fluffy particle. The starch-based fluffy particles are porous and fluffy with a large pore size, have excellent water absorption speed, water absorption rate and degradation rate, and can achieve the purpose of rapid and efficient hemostasis. Moreover, the starch-based fluffy particles are free of dispersing agent, emulsifying agent or cross-linking agent, have the characteristics of safety and reliability, and can meet the hemostatic requirement of in-vivo environment.
