Soy protein, with proper processing, enjoys several advantages such as the ability to form a network structure for use as resin [67]. It can be processed into films for use as garbage and grocery bags [68], edible films [69,70] and adhesives in particle board and plywood [71, 72], Soy protein resin has also been combined with natural fibers to produce reinforced composites [19-24, 35, 36]. Some of these efforts are described later in this chapter.

Soy protein resins, however, have three major disadvantages. First, soy protein contains many polar amino acids, which indicate its highly hydrophilic nature that allows large amount of moisture to be absorbed. Second, soy protein resins show brittle behavior when they are in dry conditions. In other words, soy protein properties are water sensitive. Third, soy protein resin shows low tensile strength. These disadvantages have limited their applications. Plasticizers and cross-linkers...
