Excerpt from On the Chemical Constitution of the Proteins of Wheat Flour and Its Relation to Baking Strength: A Thesis Submitted to the Faculty of the Graduate School of the University of Minnesota Gliadin-glutenin rat10 - As soon as Osborne and Voorhees,1 in 1893, established the composition and properties of the wheat proteins, attention was at tracted to gliadin and glutenin, the two conspicuous and characteristic proteins of wheat, which were shown to make up the gluten, the more or less elastic binding material which enables flour to be made into the dough with its characteristic elastic, gas-retaining property, and which may be separated from the starch and soluble proteins by the well-known process of washing the dough in a stream of water. 'fleurent, ' in 1896, claimed that flour strength depends on the proportion of gliadin to glutenin present in the gluten of the flour. He concluded from his experiments that the optimum ratio was 75 parts of gliadin to 25 of glutenin or He assigned certain limits, outside of which flours were said to be of poor baking quality. Snyder,3 in 1899, published similar results, although he fixed his ideal ratio at He also states' that the quality rather than the quantity of gluten is the important factor, because he was able to add up to 20 per cent starch to flour without decreasing its baking quality. Regarding the quantity of gluten in flour, the amount of gliadin present, the ratio of gliadin to glutenin, and the relation of these to baking quality, it suffices to say that the results of difierent investi gators quite frequently are not concordant. However, as mentioned before, this is in a considerable measure due to different analytical methods employed by differ ent workers. Crude gluten - The crude gluten determination, which consists essentially of washing the gluten free from starch and soluble material by means of water.

Book Description
Excerpt from Flour Strength as Influenced by the Addition of Diastatic Ferments: A Thesis Submitted to the Faculty of the Graduate School of the University of Minnesota The baking strength of flour has received a great deal of attention by scientific workers in the last twenty-five years, due primarily to the economic importance of bread. A number of factors have been thoroughly investigated, in their relation to baking strength, in order to draw some conclusions as to why some flours give a large, light, palatable loaf of bread and others an inferior loaf. Certain factors which have been investigated in their relation to baking strength are total nitrogen, ratio of water-soluble nitrogen to total nitrogen, chemical composition of the individual proteins, total gluten, total gliadin, ratio of gliadin to glutenin, ratio of gliadin to total nitrogen, ratio of wet to dry gluten, eflFect of electrolytes, hydrogen-ion concentration, total amount of gas evolved during fermentation, and the effects of diastatic and proteolytic enzymes of the flour. Flours which bake out well have been given the arbitrary term of strong flours while the others are termed weak. Naturally a great number of definitions of strength have found their way into the literature, but the definition that has been most generally accepted is that of Humphries and Biffin(1907), who state that a strong wheat is one which yields flour capable of making large, well-piled loaves. Flours which do not measure up to this empirical standard are classed as weak. This definition indicates that strength in flour is more desirable than weakness for the baking of bread. Wood(1907), has called attention to two factors in strength, namely, size and shape of the loaf. This has stimulated a great deal of research by Ford and Guthrie(1908), Baker and Hulton(1908), on the diastatic and proteolytic enzymes in wheat flour, and also by Upson and Calvin(1915) (1916), Gortner and Doherty(1918), and Sharp and Gortner (1922), on the colloidal properties of wheat gluten as affecting flour strength. Today we must recognize three groups of factors dealing with strength or weakness in flour. According to Sharp and Gortner (1922).we have at least three classes of weak flour, i.e., (1)weakness due to an adequate quantity of gluten but of inferior quality, (2) weakness due to an inadequate quantity of a good quality gluten and(3) weakness due to factors influencing yeast activity.

Excerpt from The Diastatic Enzymes of Wheat, Flour and Their Relation to Flour Strength: A Thesis Submitted to the Faculty of the Graduate, School of the University of Minnesota; In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy; June, 1922 Gluten Content - Because Of the unique property Of wheat pro teins to form a tenacious, elastic framework of gluten for the reten tion Of the aerating gas, attention was first turned to the amount and character Of the gluten content. The numerous contributions Of Osborne (1895 to Guthrie Fleurent Snyder Guess Humphries (1907 Guthrie and Norris Wood and Hardy Bailey Blish Upson and Calvin Swanson and Tague Gortner and Doherty and others have led to the conclusion that in the proteins of the flour, and especially in the gluten, is to be found the most important basis for differences in baking value. Protein Analyses. - Ou the other hand Fleurent Snyder Shutt (1905 Norton Chamberlain Wood Thatcher Armstrong Ladd and Bailey Bailey (1913 Blish and Martin have Shown that percentage relationships from protein analyses would not suffice for the predetermination Of flour strength. Neither does the accurate characterization Of the proteins by Osborne and his CO workers apply directly to the problem Of strength.
