Wheat Gluten is the water-insoluble complex protein fraction sepa-
rated from wheat flours. gum gluten is wheat gluten in its freshly
extracted wet form. dry gluten is approximately 70–80% protein
but is deficient in the amino acid lysine. it absorbs two to three
times its weight in water. the differences in properties of wheat glu-
ten in comparison to almost all other food proteins are largely due
to the low polarity level of the total amino acid structure. most food
proteins have polar group levels of 30–45% and have a net negative
charge, while wheat gluten has a polar group level of approximately
10% with a net positive charge. this results in the repulsion of excess
water and the close association of the wheat gluten molecules and
resistance to dispersion. in baked goods, this results in the ability to
form adhesive, cohesive masses, films, and three-dimensional net-
works. gluten formation is utilized in the baking industry to impart
dough strength, gas retention, structure, water absorption, and
retention with breads, cakes, doughnuts, and so on. it is also used as
a formulation aid, binder, filler, and tableting aid. see gluten;
