Abstract
Abstract A hermetically sealed food system is provided which includes a container, a special low moisture precooked rice, a seasoning ingredient containing a hygroscopic material such as hydrolyzed vegetable protein. The precooked rice component is dried to a low moisture content such that it is rendered sufficiently hygroscopic so that it will prevent any substantial increase in the amount of moisture in the seasoning ingredient.
