PROBLEM TO BE SOLVED: To provide an improved binder, particularly a binder which is compatible with an established manufacturing process, ii) is environmentally acceptable, and iii) overcomes the above-mentioned problems. As a first aspect, the present invention provides a water soluble pre-reacted binder comprising a reaction product of (i) at least one carbohydrate component and (ii) at least one polyamino acid component. A composition is provided. The pre-reacted binder is in the form of an aqueous solution or dispersion containing at least 20 wt%, for example at least 25 wt% pre-reacted binder composition and/or not more than 85 wt% pre-reacted binder composition. It may be. A preferred embodiment of the pre-reacted binder composition of the present invention is based on an alkaline carbohydrate component/polyamino acid component binder system; that is, the carbohydrate component and the polyamino acid component are the major reactive components of the starting material. ..
