The objective of this study was to determine the effects of carbohydrates on the water resistances and bonding strengths of soy-based adhesives (SBAs). Defatted soy flour (DSF), soy protein isolate (SPI), sucrose, and glucose were used to prepare SBAs, and the mechanisms of water resistance, hydrophilicity, and bonding strength (boiling-water test) were investigated. Fourier-transform infrared and X-ray photoelectron spectroscopies showed that the cross-linking and hydrophobicities of cured SBAs were enhanced by Maillard reactions between soy protein and sucrose and glucose. SBAs prepared with SPI and DSF had the lowest and highest water absorptions, respectively. The highest bonding strength was 0.73 MPa, for a glucose content in the SBA of 71 wt%. The lowest bonding strength was observed in a cured SBA prepared from DSF. A reduced carbohydrate content, or increased sucrose and glucose fractions in the carbohydrate, decreased the hydrophilicity and increased the bonding strength of the cured SBA.
