Abstract: A method for modifying a gliadin and an application thereof are provided. The method includes the following steps: dissolving the gliadin in a solvent to obtain gliadin solution; and adding a proline endoprotease to the gliadin solution for a reaction, and adjusting the pH value of solution to neutral according to a gradient, to obtain a modified gliadin. The modified gliadin obtained by the present invention may be uniformly dispersed in water, and may still maintain a uniform dispersion state in the water after high-temperature thermal sterilization and long-term storage, or even in the presence of sodium chloride, it has good thermal stability, salt resistance, and storage stability.

Abstract: The present invention is directed to crystalline polymorphs of benfotiamine, its methods of preparation and its use thereof. Five crystalline polymorphs of benfotiamine are designated as crystalline forms A, B, C, D and E, and may be distinguished by their respective patterns of X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), infrared spectroscopy (IR), raman spectroscopy, moreover by their diverse preparing process. The crystalline polymorphs of the present invention are useful as they act in treating Vitamin B1 deficiency, metabolic disorders, mental illness and disorders, diabetes complications, neurodegerative diseases. Further the present invention is a process for preparing and transforming diverse crystalline form of benfotiamine through different synthesis routes and varied solvents and combinations. The crystalline polymorphs of the present invention are basically pure.
