Textured Plant Protein Pasta Product and Method
Disclosed is a method for producing textured plant protein pasta products. The method provides a means for forming pasta products of various kinds having at least about 55 percent protein by weight. The resulting products can be formed in a variety of sizes and shapes and used in a variety of applications for which pasta is commonly used.
1 . A method for producing a high-protein pasta product, the method comprising the steps of
(a) admixing water, transglutaminase, and at least one plant protein composition selected from the group consisting of protein isolate, protein concentrate, and combinations thereof, to produce a water/transglutaminase/protein admixture that forms a gelatinized protein cake; and
(b) processing the gelatinized protein cake by extrusion to produce a formed protein pasta product.
2 . The method of claim 1 , further comprising a step (c) drying the formed protein pasta product at a drying temperature of from about 60 to about 300 degrees Celsius, to produce a low moisture, shelf-stable high protein pasta product.
3 . The method of claim 1 , wherein the plant protein is pulse protein.
4 . The method of claim 3 , wherein the pulse protein is selected from the group consisting of at least one isolate, at least one concentrate, or a combination thereof, from Pisum sativum.
5 . The method of claim 1 , wherein the holding admixture is held for a period of from 0.5 minutes to about 60 minutes to allow the gelatinized protein cake to form before it is processed according to step (b).
6 . The method of claim 1 , wherein the ratio of water to pea protein in the admixture comprises from about 60:40 to about 40:60.
7 . The method of claim 1 , wherein the transglutaminase is added at from about 0.001 percent to about 10 percent of the admixture, by weight.
8 . The method of claim 1 , wherein the transglutaminase is present at from about 0.01% to about 10%, by weight.
9 . The method of claim 1 , wherein the transglutaminase is a microbial transglutaminase.
10 . The method of claim 1 , wherein the extrusion is performed using a pasta extruder.
11 . The method of claim 1 , wherein the plant protein is selected from the group consisting of proteins from red lentils, green lentils, yellow lentils, brown lentils, chickpeas, garden peas, black-eyed peas, runner beans, fava beans, kidney beans, and combinations thereof.
12 . A high-protein pasta product comprising at least 70 percent pulse protein.
13 . The high-protein pasta product of claim 12 , wherein the pulse protein is gelatinized by crosslinking the protein with transglutaminase.
14 . The high-protein pasta product of claim 12 , wherein the pulse protein comprises at least one isolate, at least one concentrate, or a combination thereof, from Pisum sativum.
