Abstract
Abstract Nonnutritive flavor imparting compounds of the general formula (F--Z) n C wherein F is an active flavor imparting agent, C is a controlling agent for transporting and essentially restricting absorption of the compound (F--Z) n C in a biological environment, Z is a covalent bond for bonding F to C and n is at least one. The nonnutritive flavor imparting compounds are useful for imparting flavor and taste to foods, beverages, confections and medicinals without any substantial absorption of the flavor imparting compounds in the environment of use.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A method for imparting a flavor to an edible comestible comprising adding thereto an effective amount of a nonnutritive, nonabsorbable, water soluble flavor imparting compound comprising an active flavoring agent bound through a bondable position that is not essential for its flavor imparting activity with a biologically nonrupturable covalent bond that maintains its physical and chemical integrity under primary gastrointestinal digestive conditions to a polymeric nonmetabolizable nonbiodegradable controller molecule having a molecular weight in excess of 400 and dimensions such that the compound has a molecular weight in excess of 1000 and dimensions that essentially prevent the active and passive absorption of the compound from the mucosal to the serosol side of the gastrointestinal tract of a warm blooded host as the compound passes through said gastrointestinal tract.
Claim 2
Independent Claim
128 words
A method for imparting a flavor to an edible comestible comprising adding thereto an effective amount of a nonnutritive, nonabsorbable, water soluble flavor imparting compound comprising an active flavoring agent bound through a bondable position that is not essential for its flavor imparting activity with a biologically nonrupturable covalent bond that maintains its physical and chemical integrity under primary gastrointestinal digestive conditions to a polymeric nonmetabolizable nonbiodegradable controller molecule having a molecular weight in excess of 400 and dimensions such that the compound has a molecular weight in excess of 1000 and dimensions that essentially prevent the active and passive absorption of the compound from the mucosal to the serosol side of the gastrointestinal tract of a warm blooded host as the compound passes through said gastrointestinal tract.
Claim 3
Dependent Claim
134 words
A comestible composition of matter comprising an essentially nonabsorbable, nonnutritive, water soluble flavor imparting compound of the general formula (F--Z) n C wherein F is a biologically active flavor imparting agent, Z is a covalent bond that permanently bonds the flavor imparting agent to C and is essentially unaltered under the conditions of passage through the gastrointestinal tract, n is at least one, and C is a polymeric controller molecule other than F that is substantially indigestible and non-absorbable and has a molecular weight in excess of 400 and a three dimensional space occupying group of molecular dimensions that prevent (F--Z) n C absorption through the mucosa of the gastrointestinal tract as the flavor imparting compound passes through the gastrointestinal tract, and wherein the flavor imparting compound is admixed with an edible comestible substance.
Claim 4
Dependent Claim
134 words
A comestible composition of matter comprising an essentially nonabsorbable, nonnutritive, water soluble flavor imparting compound of the general formula (F--Z) n C wherein F is a biologically active flavor imparting agent, Z is a covalent bond that permanently bonds the flavor imparting agent to C and is essentially unaltered under the conditions of passage through the gastrointestinal tract, n is at least one, and C is a polymeric controller molecule other than F that is substantially indigestible and non-absorbable and has a molecular weight in excess of 400 and a three dimensional space occupying group of molecular dimensions that prevent (F--Z) n C absorption through the mucosa of the gastrointestinal tract as the flavor imparting compound passes through the gastrointestinal tract, and wherein the flavor imparting compound is admixed with an edible comestible substance.
Claim 5
Dependent Claim
34 words
A comestible composition according to claim 1 wherein the composition contains from 0.001 percent to 10 percent of the essentially nonabsorbable, nonnutritive flavor imparting compound based on the total weight of the comestible substance.
