Abstract
Abstract Described are smoking tobacco compositions or substitute smoking tobacco compositions which, on fabrication into a smoking article, on smoking, yield a high flavor intensity release substantially evenly and uniformly over an extended period of time; the smoking tobacco composition or substitutes therefor containing a mixture of (i) a non-confined flavor oil; (ii) a flavor oil which is physically entrapped in solid particles; and (iii) a suspending agent such as hydroxypropyl cellulose; the none-confined flavor oil, the entrapped flavor oil and the suspension agent being premixed prior to addition to said smoking tobacco or said smoking tobacco substitute.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A smoking tobacco or substitute smoking tobacco comprising a composition consisting essentially of: a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose, having a molecular weight of from about 50,000 up to about 800,000, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil, and shredded tobacco within which the resulting suspension is uniformly distributed whereby as the tobacco is smoked during the smoking activity, the flavor is released at a high flavor intensity substantially evenly and iniformly over an extended smoking activity time.
Claim 2
Dependent Claim
178 words
A smoking tobacco or substitute smoking tobacco comprising a composition consisting essentially of: a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose, having a molecular weight of from about 50,000 up to about 800,000, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil, and shredded tobacco within which the resulting suspension is uniformly distributed whereby as the tobacco is smoked during the smoking activity, the flavor is released at a high flavor intensity substantially evenly and iniformly over an extended smoking activity time.
Claim 3
Dependent Claim
169 words
A smoking article comprising tobacco, a wrapper holding the tobacco in place and a filter in contact with said tobacco and said wrapper and in intimate contact with the filter or the wrapper or the tobacco a composition consisting essentially of: a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of hydroxypropyl cellulose, colloidal silica, xanthan gum and ethyl cellulose, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil.
Claim 4
Dependent Claim
169 words
A smoking article comprising tobacco, a wrapper holding the tobacco in place and a filter in contact with said tobacco and said wrapper and in intimate contact with the filter or the wrapper or the tobacco a composition consisting essentially of: a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of hydroxypropyl cellulose, colloidal silica, xanthan gum and ethyl cellulose, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil.
Claim 5
Dependent Claim
160 words
A process for augmenting or enhancing the aroma or taste of a smoking tobacco comprising the step of adding to smoking tobacco an aroma or taste augmenting or enhancing quantity of a composition consisting essentially of: a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil beig organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil.
Claim 6
Dependent Claim
160 words
A process for augmenting or enhancing the aroma or taste of a smoking tobacco comprising the step of adding to smoking tobacco an aroma or taste augmenting or enhancing quantity of a composition consisting essentially of: a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil beig organoleptically compatible with said non-confined hydrophobic flavor oil; c. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000, whereby the physically entrapped flavor oil is suspended in the non-confined flavor oil.
Claim 7
Dependent Claim
