Abstract
The present invention is directed to a process and product by process for preparing a carbohydrate polymer which comprises polymerizing a sugar at a temperature below the point of substantial decomposition thereof and under reduced pressure in the presence of a catalytic effective amount of an organic acid selected from the group consisting of a monocarboxylic acid, a lactone of a monocarboxylic acid and arylol, while removing water formed during said polymerization, said organic acid being non-volatile and having only one acidic functionality and having no amino groups thereon.
Claims95
A process for preparing a carbohydrate polymer which comprises polymerizing a sugar selected from the group consisting of a monosaccharide, dissacharide, oligosaccharide and hydrolysate of a carbohydrate polymer at a temperature below the point of substantial decomposition of said sugar and under reduced pressure and under conditions effective for polymerization in the presence of a catalytic effective amount of an organic acid thereof while removing water formed during said polymerization, said organic acid being a monocarboxylic acid or lactone thereof or arylol.
A carbohydrate polymer associated with a monocarboxylic acid or lactone thereof.
A process for administering an edible organic acid to an animal which comprises
- (a) polymerizing a sugar selected from the group consisting of a monosaccharide, disaccharide, oligosaccharide and hydrolysate of a carbohydrate polymer at a temperature below the point of substantial decomposition of said sugar and under reduced pressure under polymerization effective conditions in the presence of a catalytic effective amount of an edible organic acid thereof while removing water formed during said polymerization, said organic acid being non-volatile, wherein said organic acid is a monocarboxylic acid or lactone thereof or arylol;
- (b) adding the product of (a) to foodstuff or feed;
- and
- (c) administering the foodstuff or feed of (b) to said animal.
A process of making a food which comprises
- (a) polymerizing a sugar selected from the group consisting of a monosaccharide, disaccharide, oligosaccharide and hydrolysate of a carbohydrate polymer at a temperature below the point of substantial decomposition of said sugar and under reduced pressure and under polymerization effective conditions in the presence of a catalytic effective amount of an edible organic acid thereof while removing water formed during said polymerization, said organic acid being non-volatile, wherein said organic acid is a monocarboxylic acid or lactone thereof or arylol:
- (b) adding the product of (a) to foodstuff or feed.
A foodstuff or feed containing a polymerized carbohydrate polymer prepared by the process comprising:
- (a) polymerizing a sugar selected from the group consisting of a monosaccharide, disaccharide, oligosaccharide and hydrolysate of a carbohydrate polymer at a temperature below the point of substantial decomposition of said sugar and under reduced pressure under polymerization effective conditions in the presence of a catalytic effective amount of an edible organic acid thereof while removing water formed during said polymerization, said organic acid being non-volatile, said organic acid being a monocarboxylic acid or lactone thereof or arylol;
- and
- (b) adding the product of (a) to foodstuff or feed.
