Long Life Dough Package

Abstract

This invention relates to a packaging material for unbaked dough products which includes a container that is impermeable to water vapor transmission, a relative humidity control device in the container, dough, and a water permeable sheet forming a cover for the container wherein the relative humidity control device includes a water vapor permeable container containing a solidified humectant composition which further includes a humectant salt, water and carrier.

1 . A package comprising:
 an outer container having a portion that is permeable to water vapor; and   a water vapor permeable container disposed in the outer container and containing solidified humectant comprising a humectant salt, water, and a carrier.   
     
     
         2 . The package of  claim 1 , further comprising a dough product disposed in the outer container. 
     
     
         3 . The package of  claim 1 , wherein the outer container comprises a base and a cover disposed on the base. 
     
     
         4 . The package of  claim 1 , wherein the base is impermeable to water vapor and the cover is permeable to water vapor. 
     
     
         5 . A package comprising:
 an outer container having a portion that is at least partially permeable to water vapor; and   a water vapor permeable container disposed in the outer container and containing, at 95% humidity, a solid portion of humectant salt and a liquid portion of the humectant salt in water.   
     
     
         6 . The package of  claim 5 , further comprising a carrier disposed in the water vapor permeable container. 
     
     
         7 . The package of  claim 5 , wherein the water vapor permeable container comprises a relative humidity control device having a water activity of between 0.93 and 0.98. 
     
     
         8 . The package of  claim 5 , wherein the humectant salt maintains the relative humidity in the package at between 90 and 99%. 
     
     
         9 . The package of  claim 5  further comprising a dough product disposed in the outer container.
