Multi-purpose lignin-carbohydrate binding system
A granule includes (i) particles comprising an active agent and (ii) a binding agent comprising a lignosulfonate and a mixture of polyols. A ratio of lignosulfonate to the mixture of polyols is in the range of 1.5:1 to 16:1. The mixture of polyols may include monosaccharides, disaccharides, hydrogenated starch hydrolysates, or combinations thereof. The active agent may be an agriculturally active agent, a pharmaceutically active agent, or a food product. The granule may have a sphericity of at least 85%.
