A preparation method of the starch-containing microsphere includes the steps of first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres thus prepared are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 m.

A delivery device for an active agent comprises nanoparticles based on a biopolymer such as starch. The delivery device may also be in the form of an aptamer-biopolymer-active agent conjugate wherein the aptamer targets the device for the treatment of specific disorders. The nanoparticles may be made by applying a high shear force in the presence of a crosslinker. The particles may be predominantly in the range of 50-150 nm and form a colloidal dispersion of crosslinked hydrogel particles in water. The biopolymer may be functionalized. The aptamer may be conjugated directly to the cross-linked biopolymers. The active agent may be a drug useful for the treatment of cancer. The delivery device survives for a period of time in the body sufficient to allow for the sustained release of a drug and for the transportation and uptake of the conjugate into targeted cells. However, the biopolymer is biocompatible and resorbable.

A method for obtaining an improved plasticized material results from two differentiated steps: an esterification reaction for synthesizing a polycarboxylic acid ester oligomer in the presence of excess polyol and a catalyst, and a second step of gelatinization and plasticization at temperatures above 90? C. involving a starch mixed with water and with the polycarboxylic acid ester oligomer with excess polyol obtained in the previous step, and a coadjuvant. The catalyst used in the esterification reaction is the same as the coadjuvant used in the gelatinization and plasticization reaction. The plasticized material obtained with this method has a higher stability and a lower migration rate than known plasticized materials.

Disclosed is a method for preparing a resistant dextrin product by using compound enzyme treatment. Starch is first subjected to high-temperature acidolysis to obtain pyrodextrin which is used as the substrate for the enzyme treatment. A compound enzyme reaction system including a starch branching enzyme and a CGTase is used for preparing the resistant dextrin product. The starch branching enzyme and the CGTase are added simultaneously or sequentially to treat the pyrodextrin to further increase the content of the resistant component in the product. The content of the resistant component of the enzyme treated product reaches up to 65.3%, a 21.3% increase from that of the pyrodextrin before the enzyme treatment.
