The present disclosure provides an engineered wood precursor mixture. The mixture includes a wood substrate(s) and a binder reaction mixture present in a range of from 3 to 25 parts per one hundred (100) parts of the dry weight of the wood substrate. The binder composition includes an aqueous portion. The aqueous portion includes a carbohydrate-containing component, including glucose, fructose, sucrose, or mixture thereof, in a range of from 2 wt % to 85 wt % based on a dry weight of the binder reaction mixture. The aqueous portion further includes 1 wt % to 33 wt % of a base based on a dry weight of the binder reaction mixture, wherein a pH of the aqueous portion is greater than 10. The binder composition further includes a partially non-dissolved polypeptide-containing component, in a range of from 20 wt % to 85 wt % based on the dry weight of the binder reaction mixture.

The present invention has for its object to provide an adhesive composition that is based on a naturally occurring material less likely to have adverse influences on the human body and has a tensile shear strength (adhesive strength) of at least 1 MPa with respect to a variety of adherends. The present invention provides an adhesive composition including at least a first pack and a second pack, wherein the first pack contains a tannic acid derivative in which a hydrogen atom in at least some hydroxyl group of tannic acid is substituted by a chain hydrocarbon group having at least one hydroxyl group, and the second pack contains a hydrocarbon having at least two cyanate groups or a derivative of the hydrocarbon.
