Listing description
Gluten (from Latin gluten, "glue") is a composite of storage
proteins termed prolamins and glutelins[1] found
in wheat and
related grains, including barley, rye, oat, and all their species and hybrids (such
as spelt, khorasan, emmer, einkorn, triticale, etc.).[2]Gluten is
appreciated for its viscoelastic properties.[3][4] It gives
elasticity to dough, helping
it rise and keep its shape and often gives the final product
a chewy texture.
Detailed description
Uses
Bread products
Gluten forms when glutenin molecules cross-link to
form a submicroscopic network attached to gliadin, which contributes viscosity(thickness) and
extensibility to the mix.[3][10] If this dough
is leavened with yeast, fermentation produces carbon dioxide bubbles,
which, trapped by the gluten network, cause the dough to rise. Baking coagulates the gluten, which, along with starch, stabilizes the shape
of the final product. Gluten content has been implicated as a factor in
the staling of bread,
possibly because it binds water through hydration.[11]
The development of gluten (i.e., enhancing its
elasticity) affects the texture of the baked goods.[3] Gluten's
attainable elasticity is proportional to its content of glutenins with low
molecular weights as this portion contains the preponderance of the sulfur
atoms responsible for the cross-linking in the network.[12][13] More refining
(of the gluten) leads to chewier products such as pizza and bagels, while less refining yields tender baked goods such as pastry products.[14]
Generally, bread flours are high in gluten (hard wheat); pastry flours have
a lower gluten content. Kneading promotes the
formation of gluten strands and cross-links, creating baked products that are
chewier (in contrast to crumbly). The "chewiness" increases as the
dough is kneaded for longer times. An increased moisture content in the dough
enhances gluten development,[14] and very wet
doughs left to rise for a long time require no kneading (see no-knead bread). Shortening inhibits
formation of cross-links and is used, along with diminished water and less
kneading, when a tender and flaky product, such as a pie crust, is desired.
The strength and elasticity of gluten in flour is
measured in the baking industry using a farinograph. This gives the baker a
measurement of quality for different varieties of flours in developing recipes
for various baked goods.[3][15][16]
Added gluten
Gluten, when dried and milled to a powder and added
to ordinary flour dough, improves a dough's ability to rise and increases the
bread's structural stability and chewiness.[17]Gluten-added dough
must be worked vigorously to induce it to rise to its full capacity; an
automatic bread machine or food processor may be
required for high-gluten kneading.[18]Generally, higher
gluten levels are associated with higher amounts of overall protein.[19]
Imitation meats
Gluten, especially wheat gluten, is often the basis
for imitation meats resembling beef, chicken, duck (see mock duck), fish, and pork. When cooked in broth, gluten absorbs some of the surrounding liquid (including the
flavor) and becomes firm to the bite.[20][21]
Other consumer products
Gluten is often present in beer and soy sauce, and can be used as
a stabilizing agent in
more unexpected food products, such as ice creamand ketchup. Foods of this kind
may raise a problem for a small number of consumers because the hidden gluten
constitutes a hazard for people with celiac disease.
