Sufficient agitation in the presence of a small amount of water results in complex formation and bonding into strong agglomerates. The agglomerates are strong and stable and useful inter alia in foods (the guest molecules are flavors), pharmaceuticals (the guest molecules are drugs) and agriculture (the guest molecules are various agrochemicals).Other References
