Abstract Epichlorohydrin-inhibited, hydroxypropyl starch products are described, said products displaying a thin viscosity on normal cooking with water but display a higher viscosity upon being heated at retort temperatures. Such starch products find a particular use in the commercial preparation of canned foods.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
A RETORTABLE FOOD PRODUCT CONTAINING A STARCH THICKENER IN WHICH A SUBSTANTIAL PORTION OF THE STARCH THEREIN IS AN EPICHLOROHYDRIN CROSS-LINKED HYDROXYPROPYL CEREAL STARCH HAVING A HYDROXYPROPYL D.S. OF ABOUT 0.06 TO ABOUT 0.30 AND A PH 3 BUFFERED BRABENDER VISCOSITY OF 250-600 BU AT 92*C. AND 475-650 BU AT 92*C. PLUS 10 MINUTES, WITH THE VISCOSITY AT 92*C. PLUS 10 MINUTES GREATER THAN THE VISCOSITY AT 92*C.
Claim 2
Dependent Claim
68 words
A RETORTABLE FOOD PRODUCT CONTAINING A STARCH THICKENER IN WHICH A SUBSTANTIAL PORTION OF THE STARCH THEREIN IS AN EPICHLOROHYDRIN CROSS-LINKED HYDROXYPROPYL CEREAL STARCH HAVING A HYDROXYPROPYL D.S. OF ABOUT 0.06 TO ABOUT 0.30 AND A PH 3 BUFFERED BRABENDER VISCOSITY OF 250-600 BU AT 92*C. AND 475-650 BU AT 92*C. PLUS 10 MINUTES, WITH THE VISCOSITY AT 92*C. PLUS 10 MINUTES GREATER THAN THE VISCOSITY AT 92*C.
Claim 3
Dependent Claim
90 words
A retortable food product containing a starch thickener in which a substantial portion of the starch therein is an epichlorohydrin cross-linked hydroxypropyl cereal starch having a hydroxypropyl D.S. of about 0.06 to about 0.30, said cross-links having been obtained by employing from about 0.015 to about 0.023 parts of epichlorohydrin to 100 parts of starch, and having a pH 3 buffered Brabender viscosity of 250-600 BU at 92*C. and 475-650 BU at 92*C. plus 10 minutes, with the viscosity at 92*C. plus 10 minutes greater than the viscosity at 92*C.
Claim 4
Dependent Claim
90 words
A retortable food product containing a starch thickener in which a substantial portion of the starch therein is an epichlorohydrin cross-linked hydroxypropyl cereal starch having a hydroxypropyl D.S. of about 0.06 to about 0.30, said cross-links having been obtained by employing from about 0.015 to about 0.023 parts of epichlorohydrin to 100 parts of starch, and having a pH 3 buffered Brabender viscosity of 250-600 BU at 92*C. and 475-650 BU at 92*C. plus 10 minutes, with the viscosity at 92*C. plus 10 minutes greater than the viscosity at 92*C.
Claim 5
Dependent Claim
19 words
A retortable food product according to claim 1 wherein said epichlorohydrin cross-linked hydroxypropyl cereal starch is in granular form.
Claim 6
Dependent Claim
18 words
A retortable food product according to claim 1 wherein said epichlorohydrin cross-linked hydroxypropyl cereal starch is corn starch.
Claim 7
Dependent Claim
54 words
A process for preparing a retortable food product characterized in having a starch thickener more viscous after retorting than prior to retorting comprising heating a retortable food product containing the starch thickener of claim 1 to a temperature of about 240* - 250*F. for a period of time sufficient to sterilize the food product.
Claim 8
Dependent Claim
17 words
A process according to claim 5 wherein said epichlorohydrin cross-linked hydroxypropyl cereal starch is in granular form.
Claim 9
Dependent Claim
16 words
A process according to claim 5 wherein said epichlorohydrin cross-linked hydroxypropyl cereal starch is corn starch.
