Abstract

A portioned moist tobacco product with a super-hydrated membrane coating and method of manufacturing is disclosed. The super-hydrated membrane coating is formed by ionic cross-linking using two polymers. The soluble component of the super-hydrated membrane coating dissolves upon placement in the mouth, while the insoluble component maintains the tobacco within the coating for the duration of the use of the product. The moist tobacco product is soft and flexible so as to fit comfortably in an oral cavity when placed therein.
