Soy protein products having altered characteristics

Abstract

Soy protein products obtained from high oleic soybeans, wherein such products, have improved whiteness, reduced viscosity and reduced gel-strength, are described. Use of such products in food, beverage and animal feed are also disclosed.

What is claimed is: 
     
         1 . A soy protein product obtained from a high oleic soybean wherein said product has at least one characteristic selected from the group consisting of improved whiteness, reduced gel strength and reduced viscosity when compared to a soy protein product obtained from a commodity soybean using the same process as that to obtain the soy protein product from a high oleic soybean. 
     
     
         2 . The soy protein product of  claim 1 , wherein:
 a) the whiteness index is increased by at least 3%; or   b) the gel strength is reduced by at least 25%; or   c) the viscosity of an unhydrolyzed soy protein product is reduced by at least 9%.   
     
     
         3 . The soy protein product of anyone of  claims 1 , or  2  wherein said protein product has at least 40% protein (N×6.25) on a moisture-free basis. 
     
     
         4 . The soy protein product of anyone of  claims 1 , or  2  wherein said protein product has at least 65% protein (N×6.25) on a moisture-free basis. 
     
     
         5 . The soy protein product of anyone of  claims 1 , or  2  wherein said protein product has at least 90% protein (N×6.25) on a moisture-free basis. 
     
     
         6 . The soy protein product of anyone of  claims 1 , or  2  wherein said product is selected from the group consisting of a soy protein isolate, a soy protein concentrate, soy meal, full fat flour, soymilk powder, defatted flour, soymilk, textured proteins, textured flours, textured concentrates and textured isolates. 
     
     
         7 . A food which has incorporated therein the soy protein product of anyone of  claims 1 , or  2 . 
     
     
         8 . A beverage which has incorporated therein the soy protein product of anyone of  claims 1 , or  2 . 
     
     
         9 . Animal feed which has incorporated therein the soy protein product of anyone of  claims 1 , or  2 . 
     
     
         10 . A method for improving drying efficiency of a soy protein product, comprising feeding at least one soy protein product obtained from a high oleic soybean seed at higher feed solids to a pasteurizer or a dryer compared to feeding at least one soy protein product obtained from a commodity soybean. 
     
     
         11 . A method for improving drying efficiency of a soy protein product, comprising feeding at least one soy protein product obtained from a high oleic soybean seed at no less than 14% feed solids to a pasteurizer or a dryer
