Abstract

Abstract An amylaceous material having alkaline viscosities in the range of 10 to 20 seconds using a 1.3 g sample and 15 to 20 seconds using a 5.2 g sample and having cold water solubles of between 50% and 98% is made by hydrolysis of starting material such as corn, flour, corn meal, corn grits, corn starch, sorghum flour, sorghum meal and sorghum grits at moistures between 5% and 12%, adjusting the pH of the hydrolyzed amylaceous material to between pH 3 and 6, gelatinizing the pH adjusted hydrolyzed amylaceous material, and removing water from the gelatinized product.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 123 words
The method of manufacturing amylaceous material comprising the steps in the following sequence: (a) hydrolyzing a material selected from the group consisting of corn flour, corn meal, corn grits, corn starch, sorghum flour, sorghum meal and sorghum grits at moistures between 5 and 12% by weight of the humidified starting material using between 0.1 and 2% by weight acid; (b) adjusting the pH of the acid hydrolyzed amylaceous material to between pH 3 and 6 obtained on a 10% solids water slurry; (c) gelatinizing the pH adjusted acid hydrolyzed amylaceous material at moisture levels between 15 and 40% and at temperatures of between 212° and 400° F.; (d) removing water from the gelatinized product; (e) comminuting the dried amylaceous mass to a flour.
Claim 2
Independent Claim 123 words
The method of manufacturing amylaceous material comprising the steps in the following sequence: (a) hydrolyzing a material selected from the group consisting of corn flour, corn meal, corn grits, corn starch, sorghum flour, sorghum meal and sorghum grits at moistures between 5 and 12% by weight of the humidified starting material using between 0.1 and 2% by weight acid; (b) adjusting the pH of the acid hydrolyzed amylaceous material to between pH 3 and 6 obtained on a 10% solids water slurry; (c) gelatinizing the pH adjusted acid hydrolyzed amylaceous material at moisture levels between 15 and 40% and at temperatures of between 212° and 400° F.; (d) removing water from the gelatinized product; (e) comminuting the dried amylaceous mass to a flour.
Claim 3
Dependent Claim 14 words
The method claimed in claim 1 wherein the pH adjustment is accomplished with ammonia.
Claim 4
Dependent Claim 14 words
The method claimed in claim 1 wherein the gelatinization is accomplished by an extruder.
Claim 5
Dependent Claim 14 words
The method claimed in claim 1 wherein the gelatinization is accomplished by an expander.
Claim 6
Dependent Claim 27 words
The method claimed in claim 1 wherein the alkaline viscosity of the acid modified material is less than 20 seconds using a 1.3 g sample before gelatinization.
Claim 7
Dependent Claim 42 words
A product formed by the process of claim 1 wherein the product has alkaline viscosities of less than 20 seconds at 1.3 g sample and less than 100 seconds using a 5.2 g sample and cold water solubles of at least 50%.
Claim 8
Dependent Claim 28 words
The method claimed in claim 1 wherein the hydrolysis is carried out with an acid selected from the group consisting of HCl and H 2 SO 4 .
Claim 9
Dependent Claim 19 words
The method claimed in claim 7 wherein the acid modification is carried out at a temperature between 150°-200° F.
