Allen et al. (2007) produced puffed snack foods with com starch and pregelatinized waxy starch, WPC and instantized WPC, and protein concentrations of 16%, 32%, and 40% and showed that the air cell size, extru-date expansion ratio, and water solubility index decreased proportionally as protein and com starch levels increased. Protein concentration significantly affected total soluble protein, water absorption index, and water-soluble carbohydrate. A covalent complex between amylase and protein formed in the presence of cornstarch, but protein-protein interactions appeared with the presence of low levels of pregelatinized waxy starch. 

Other Substances. Several other index substances (W8), such as carotene, have been used by various workers in this field. There does not seem to be any particular advantage in these other methods. The use of one good water-soluble index substance, such as xylose, and one fat-soluble index substance, such as I131 fat or vitamin A in oil, is sufficient for diagnostic purposes. 

Nitrogen solubility index is inversely related to protein level, i.e., as the protein level increases, NSI decreases (8). Another factor related to solubility of seed nitrogen in a flour and distilled water suspension is the concentration of water-soluble naturally occurring salts, since salt-soluble globulins are the major proteins found in peas (21). Also, differences in pea mineral content may play a role in NSI.

Riboflavin (vitamin B2) was chosen as the number one index vitamin because among the so-called water-soluble vitamins, it is the least soluble in water. If riboflavin is demonstrated to dissolve within the specified time, it is assumed that all other water-soluble vitamins will have also... 

In contrast to the dissolution criteria used for water-soluble vitamins, the hierarchy for index minerals is based on their importance in public health. For example, iron was chosen as the number one index mineral because iron deficiency is the most prevalent condition in the United States and because iron is present in almost all the multivitamin-mineral combination products currently available on the...

Many publishers make available their databases on floppy disks or CD-ROMs, which are often found inside the back cover of the book. An example is the Properties of Organic Compounds (Tide and Milne 1999), which is a CD-ROM list of 27,500 known organic compounds and their formulas, molecular weights, melting points, boiling points, densities, refractive indexes, colors, solubility scales, vapor pressures, and threshold limit values (TLVs) that workers can be exposed to in a normal 8 h workday and 40 h workweek. This reference gives only a limited number of properties, and does not go into flammability or toxicity. Solubility in water is given only as a...
