Interpretive Summary:

Technical Abstract: Soy oligosaccharides (soy molasses/soy whey) and other soybean materials, including spent soybean hulls, soy flours, soy protein concentrates and soy protein isolates, were evaluated in high moisture veneer southern yellow pine test panels. The materials were incorporated as a 10% replacement for PF resins in glue mixes, with additional caustic added to make-up for caustic removed as part of the resin. In terms of wood failure, soy protein concentrates and spent hulls were the best performing materials. In terms of tensile strength, soy protein isolates and concentrates, as well as soy flour, gave the best results. It appeared that a combination of carbohydrates and protein gave the best results, with materials containing mostly one or the other not performing as well. Overall, in terms of tensile strength, wood failure and economics, spent hulls and soy protein concentrates appeared to be the best performing materials, although it was difficult to statistically differentiate the effects of many of the materials.
