摘要:
A modified starch material for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
摘要:
The present invention relates specifically to starch products and starch compositions useful for thickening aqueous liquids, for example, for use by people suffering from dysphagia. In one aspect, the invention provides a pregelatinized, hydroxypropylated starch, having a level of hydroxypropylation in the range of about 1% to about 10%; an RVA viscosity in the range of about 400 cP to about 3500 cP; wherein the pregelatinized, hydroxypropylated starch is readily dispersible in milk. Another aspect provides a provides a pregelatinized, hydroxypropylated starch, having a level of hydroxypropylation in the range of about 1% to about 10%; and an RVA viscosity in the range of about 400 cP to about 3500 cP; and less than about 80%>of the surface protein of the corresponding native starch.
摘要:
Disclosed is a cold-water soluble starch and a process for preparing same. Generally, the process comprises providing a hydroxyalkyl starch and applying a shearing force to the starch in an extruder in the presence of moisture, the force and the moisture each being sufficient to gelatinize at least substantially all of the granules of the starch to thereby form a sheared starch. The starch is heated to its gelatinization temperature after the starch has passed partially through the barrel of the extruder, with the moisture being maintained at a level sufficiently high to allow gelatinization but sufficiency low to protect the starch from becoming too sticky to extrude. The extruded starch product thus formed may be used in connection with a number of film-forming, coating, and other applications.
摘要:
A process for modifying starch is described. The process can be used as an alternative to conventional starch modification processes, such as substitution and crosslinking. The process and resulting product can reduce, substantially reduce, substantially eliminate or eliminate the sodium level typically associated with conventionally modified starch products.
摘要:
The present document describes a powder composition comprising a functionalized starch having a single helix V-structure and having a degree of substitution of at least 0.25, and a bioactive agent, forming an inclusion complex with said functionalized starch, where the bioactive agent is within the helix V-structure of the functionalized starch having a single helix V-structure. Also described are the functionalized starch having a single helix V-structure and having a degree of substitution of at least 0.25, methods of making the same and methods of using the same to manufacture the powder composition.
摘要:
A construction material composition includes a cross-linked starch derivative of a starch that is rich in amylopectin and has an amylopectin content greater than 85%.

This disclosure provides methods and compositions for the promotion of enzymatic activity of Target Enzymes, including but not limited to oligosaccharide/polysaccharide enzymes, protein enzymes, polynucleotide enzymes. The methods involve use of a non-naturally occurring polysaccharide (including but not limited HES) for promoting the enzymatic activity of an enzyme in liquid milieu, wherein the concentration of the polysaccharide in the composition comprising the Target Enzyme is from about 0.01% to about 55% w/v.
摘要:
The present invention relates to a hair fixative composition comprising a canonically modified hydrolysed starch and especially canonically modified hydrolysed starches, hydrolysed to the extend of having a dextrose equivalent of 1 to 6.
摘要:
The present invention relates to a process for preparing a chemically modified polysaccharide, preferably starch, by using a microdevice. It further relates to the use of a microdevice for the chemical reactions of polysaccharides in heterogeneous mixtures. Examples of chemical modifications are acetylation, oxidation, hydroxypropylation and the like.

A modified starch material is arranged for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
