Abstract
Abstract Processes and compositions are described for the use in foodstuff, chewing gum, toothpaste and medicinal product flavor and aroma augmenting, modifying, enhancing and imparting compositions and as foodstuff, chewing gum, toothpaste and medicinal product aroma imparting materials of cyclic acetals of 2-methyl-2-pentenal having the generic structure: ##STR1## wherein R represents either hydrogen or methyl and the wavy lines signify that the cyclic acetal moiety is in either a "cis" or "trans" configuration with respect to the ethyl moiety bonded to the ethylenic moiety of the molecule. Addition of one or more cyclic acetals of 2-methyl-2-pentenal to foodstuffs, chewing gums, toothpastes and/or medicinal products produces sweet, fruity, gooseberry, green, aniseed, licorice, floral and herbal aroma characteristics and sweet, fruity, gooseberry, green, spearmint-like, aniseed, licorice, floral and herbal flavor characteristics with albedo-like flavor nuances.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A process for augmenting or enhancing the flavor of a foodstuff comprising adding to said foodstuff from 0.5 parts per million up to about 100 parts per million based on the total weight of foodstuff of a compound having the structure: ##STR20## wherein R is selected from the group consisting of hydrogen and methyl and the wavy lines represent a "cis" or "trans" configuration with respect to the carbon-carbon double bond of the ethyl moiety with respect to the dioxolane moiety.
Claim 2
Dependent Claim
81 words
A process for augmenting or enhancing the flavor of a foodstuff comprising adding to said foodstuff from 0.5 parts per million up to about 100 parts per million based on the total weight of foodstuff of a compound having the structure: ##STR20## wherein R is selected from the group consisting of hydrogen and methyl and the wavy lines represent a "cis" or "trans" configuration with respect to the carbon-carbon double bond of the ethyl moiety with respect to the dioxolane moiety.
Claim 3
Dependent Claim
16 words
The process of claim 1 wherein in the compound added to said foodstuff, R is methyl.
Claim 4
Dependent Claim
132 words
A flavor formulation comprising (i) from about 0.1% up to about 15% by weight based on the total weight of said flavoring composition of a cyclic acetal of 2-methyl-2-pentenal having the structure: ##STR21## wherein R is selected from the group consisting of hydrogen and methyl and the wavy lines represent "cis" or "trans" configuration around the carbon-carbon double bond of said compound of the ethyl moiety with respect to the dioxolane moiety and (ii) the remainder of said composition being a material selected from the group consisting of: Oil of Cubeb; Phellandrene; Oil of Coriander; Clove Oil; p1 Cardamon Oil; Spearmint Oil; Anethole; Peppermint Oil; Oil of Pimento leaf; Oil of Patchouli; Alpha-Pinene; Beta-Pinene; Beta-caryophyllene; Dihydrocarveol; Piperonal; Piperine; Chavicine; Piperidine; Oil of Black Pepper; Black Pepper Oleoresin; Capsicum; and Oil of Nutmeg
