Starch Encapsulation Of Biologically Active Agents By A Continuous Process

View page
US Patent:
51836904, Feb 2, 1993
Filed:
Jun 25, 1990
Appl. No.:
7/542566
Inventors:
Merle E. Carr - Chillicothe IL
William M. Doane - Morton IL
Robert E. Wing - Peoria IL
Edward B. Bagley - Morton IL
Assignee:
The United States of America, as represented by the Secretary of
Agriculture - Washington DC
International Classification:
B01J 1304
A29C 4700
A61K 962
A61K 916
US Classification:
42721331
Abstract:
Biologically active agents to be encapsulated are continuously blended with a starchy material and water, subjected to high-shear mechanical action at a temperature above the gelatinization temperature of starch, and continuously recovered as an insolubilized matrix of starch that entraps discontinuous domains of the agent. Alternatively, the core material to be encapsulated is added and blended with the aqueous dispersion of starch after the starch and water have been subjected to an elevated temperature sufficient to gelatinize the starch. Rate of release of agents to the environment can be controlled by preselecting a set of conditions related to various processing parameters. Encapsulation of biologically active compositons provides protection against degradative environmental conditions, improves safety in handling, and slows the release of such compounds to the surrounding medium.

Interpolymer Paper Strength Additives

US Patent:
41521994, May 1, 1979
Filed:
May 30, 1975
Appl. No.:
5/582517
Inventors:
George E. Hamerstrand - Peoria IL
Merle E. Carr - Chillicothe IL
Assignee:
The United States of America, as represented by the Secretary of
Agriculture - Washington DC
International Classification:
D21D 300
US Classification:
162164R
Abstract:
Crosslinked starch-polyamide-polyamine interpolymers are prepared and described. Wet- and dry-tensile, dry-burst, and concora crush strengths of paper products, prepared from both acid and alkaline pulp furnishes, are significantly increased by the wet-end addition of the interpolymers.

Xanthated Starch Amine Paper Additives

View page
US Patent:
40935108, Jun 6, 1978
Filed:
Apr 7, 1977
Appl. No.:
5/785616
Inventors:
Merle E. Carr - Chillicothe IL
Assignee:
The United States of America as represented by the Secretary of
Agriculture - Washington DC
International Classification:
D21D 300
US Classification:
162175
Abstract:
Novel amphoteric starch derivatives, xanthated starch amines, have been employed as wet-end paper additives for improving both wet and dry strength. They are easily repulpable, readily biodegradable, effective in a broad range of furnish pH's, and are competitive on a cost/performance basis with commercial systems.
