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.
