Dipping solution Dissolve 250 mg potassium iodide in 25 ml water, mix with a solution of 750 mg starch (soluble starch according to Zulkow-sky) in 25 ml water and dilute with 30 ml ethanol (99.5%) [12].

Unmodified and anionically modified starches, soluble cellulose derivatives such as carboxymethylcellulose, polyvinyl alcohol, latex and other polymers are also used in some specialised applications. Starch, however, because of its cost, is by far the most common dry strength additive, about twenty times more being used than, for example, polyacrylamide. 

Determination of the Starch.—Dextrins usually contain soluble starch, i.e, starch soluble in hot (but not in cold) water. Thus, the proportion of starch (soluble) present is represented simply by the difference between the percentages of the matters soluble in cold and hot water respectively. If unconverted starch is also present, this will be found in the residue insoluble in hot water (see section 7, above) and may be determined therein by transforming it into sugar (see Flour, section 16, p. 63). 

Maltose is put on the market in the solid form, and as syrup, which usually contains also other sugars (especially glucose) and dextrin. Of this type, too, are malt extracts, including those which are used industrially —owing to the enzymes (diastases) they contain—to render starch soluble, e.g., Diamalt, Diastojor, etc. 

On the other hand, 2 grams of the substance are dissolved in 100 c.c. of water and determinations made of the liquefying power, that is, of the capacity of the substance to render starch soluble and of the true diastatic power, that is, of the capacity to saccharify starch.

Since the partial insolubility of the starch-ceric ammonium nitrate reaction product complicates the interpretation of solubility data, we ran a second series of graft polymerizations using cobalt-60 as an initiator in an attempt to remove this variable (Table II). If combination of PAN macroradicals is occuring during graft polymerization, it should occur during cobalt-60 initiated polymerizations as well as in those initiated by ceric ammonium nitrate. In the first four reactions of Table II, starch was irradiated as a water slurry under graft polymerization conditions, but in the absence of acrylonitrile, to determine the influence of different doses of irradiation on starch solubility.

The extraneous materials are a heterogeneous group of non-structural constituents most of which are organic compounds extractable in neutral solvents such as ether, acetone, ethyl alcohol, ethyl alcohol-benzene, and water. They include waxes, fats, essential oils, tannins, resin and fatty acids, terpenes, alkaloids, starch, soluble saccharides (gums), and various cytoplasmic constituents such as amino acids, proteins, and nucleic acids. An excellent review on the general subject of wood extractives is that of Hillis (26). The distribution of cytoplasmic constituents in wood has also been reviewed recently (11, 46).

A dilute solution of I produces a more or less intense blue-violet color with starch, either dry, hydrated, or in solution, the color disappearing on the application of heat, and returning on cooling. If to a solution of starch, blued by I, a solution of a neutral salt be added, there separates a blue, flocculent deposit of the so-called iodid of starch. lodin renders starch soluble in water, and a soluble iodized starch, Amylum iodatum (TT. S.), is obtained by triturating together 19 pts. starch, 2 pts. water, and 1 pt. iodin, and drying below 40° (104° P.),...
