Abstract
Abstract A thin, edible moisture barrier consists essentially of oleaginous material and wax, and has a permeability value of less than 0.07x10-9 gm cm-2 (cm Hg)-1 cm. The barrier can be applied as a molten solution to a food product surface, cooling rapidly to form a continuous barrier that prevents the migration of moisture into, out of, or between components of the food product.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
103 words
A composition useful as a moisture barrier for a food product, said composition consisting essentially of a major portion by weight of edible oleaginous materials having a melting point above the ambient temperature, and a minor portion by weight of edible wax, said edible wax being present in an amount sufficient to nucleate solidification of said oleaginous materials from a molten state under quiescent ambient conditions, and said composition being adapted for forming a thin, continuous, adherent, pliable barrier on a surface of the food product and for being essentially impermeable to the passage of water vapor through the barrier under ambient conditions.
Claim 2
Dependent Claim
103 words
A composition useful as a moisture barrier for a food product, said composition consisting essentially of a major portion by weight of edible oleaginous materials having a melting point above the ambient temperature, and a minor portion by weight of edible wax, said edible wax being present in an amount sufficient to nucleate solidification of said oleaginous materials from a molten state under quiescent ambient conditions, and said composition being adapted for forming a thin, continuous, adherent, pliable barrier on a surface of the food product and for being essentially impermeable to the passage of water vapor through the barrier under ambient conditions.
