Abstract: There is provided esterified starch which can be produced without using a non-aqueous organic solvent and has water resistance and miscibility with another plastic, and a starch-containing plastic composition. The esterified starch is obtained such that a starch mixture containing starch and a polyhydric alcohol, which is subjected to a heat treatment, is esterified with a vinyl ester and carbonate. Since the starch in the starch mixture enters a state in which starch granules are disintegrated by the polyhydric alcohol, by heating the starch mixture containing starch and a polyhydric alcohol, it is possible to esterify the starch without using a non-aqueous organic solvent and to obtain esterified starch having a high ester substitution degree. According to the esterified starch of the present invention, it is possible to obtain a starch-containing plastic composition having high hydrophobicity, and excellent water resistance and miscibility with another plastic.

Abstract: A method for producing starch granules suitable as an excipient for an orally disintegrating tablet. Fluidized bed granulation is performed by spraying a starch paste in small amounts while a ?-starch is being fluidized using an air-fluidized bed. Subsequently, fluidized bed drying is performed at a temperature equal to or higher than the gelatinization temperature of the ?-starch. This yields starch granules having a high degree of gelatinization in comparison with the amount of ?-starch adhered to the ?-starch by the spraying of the starch paste. These starch granules alone impart satisfactory oral disintegratability and breaking strength to the tablet. Accordingly, when used as an excipient during tableting of orally disintegrating tablets, other auxiliary excipients such as saccharides or crystalline cellulose need not be added.

A liquid sweetener composition containing 65% or more and 82.5% or less fructose, 5% or more and 35% or less glucose, and 1% or more and 10% or less reducing sugar other than fructose and glucose in terms of weight ratio (anhydrous basis) with 10 to 30 weight percent of water content is provided.

Abstract: Process for manufacturing modified starch. A powdery starch composition raw material, containing a specified amount of a phosphate with respect to a raw material starch on a dry basis, is subject to esterification modification by performing a first step of heat treating by raising a temperature gradually and performing, in continuation, a second step of heat treating at a constant temperature. A temperature rise starting temperature of the first step is set within a range from an ordinary temperature to a temperature no more than a gelatinization starting temperature of the raw material starch, a temperature rise rate is set to 0.2 to 1° C./min, and a temperature rise final temperature is set to 120 to 180° C. The constant temperature treatment is normally performed at the temperature rise final temperature.

Abstract: Disclosed is a novel biodegradable block for models, which has excellent workability and machinability and has mechanical properties suitable for models, while surely ensuring its biodegradability. The block is made of a biodegradable plastic material comprising a biodegradable polymer as the base polymer. The biodegradable polymer is a mixture comprising an esterified starch having a degree of substitution (DS) of about 0.4 or more and an esterified cellulose having a DS of about 0.4 or more, in ratio by weight, the former/the latter, of being from 10/0 to 1/9. The plastic material may further contain any of ester plasticizer and organic or inorganic fillers to make the block have desired physical properties.

Abstract: The present invention relates to a starch ester having short- and long-chain acyl groups wherein hydrogens in reactive hydroxyl groups in the same starch molecule have been replaced by C2-4 short-chain acyl groups and C6-18 long-chain acyl groups. The degree of substitution by the short- and long-chain acyl groups are regulated so as to make the starch ester thermo-plasticized and moldable even in the absence of a plasticizer. Accordingly, the starch ester of the present invention can be used as a biodegradable thermoplastic plastic material which can be thermo-plasticized in the absence of a plasticizer.

Abstract: A polyester-grafted starch-polymer alloy is capable of imparting practical flexibility and toughness to moldings with no or only a little plasticizer. The polyester-grafted starch-polymer alloy comprises a blend of a polyester-grafted starch (a starch which has polyester graft chains on the starch molecule, with the terminal hydroxyl groups of the polyester graft chains and the hydroxyl groups connected directly to the starch entirely or partly blocked with the ester group) and an independent polyester (a polyester which is constructed of the same unit as said polyester graft chain, with its terminal hydroxyl groups entirely or partly blocked with the ester group) which are uniformly mixed together. A method of preparing the alloy and thermoplastic resin compositions containing the alloy also are disclosed.

The polyvinyl ester is derived from one or more saturated or unsaturated aliphatic acids or aromatic carboxylic acids having 2 to 18 carbon atoms.
