Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
A process for preparing a reaction flavor product which comprises the following steps: (a) preparing a mixture of a reducing sugar and ammonium hydroxide wherein the weight ratio of reducing sugar to ammonium hydroxide is in the range of 5-15:1; (b) adding a trace amount of a compound selected from the group consisting of an amino acid and a monoamide thereof to said mixture of step (a), wherein the ratio of reducing sugar to said compound is in the range of 200-300:1; (c) heating said mixture to a temperature in the range of 90° to 105° C.; and thereafter (d) cooling said mixture to room temperature.
Claim 2
Dependent Claim
106 words
A process for preparing a reaction flavor product which comprises the following steps: (a) preparing a mixture of a reducing sugar and ammonium hydroxide wherein the weight ratio of reducing sugar to ammonium hydroxide is in the range of 5-15:1; (b) adding a trace amount of a compound selected from the group consisting of an amino acid and a monoamide thereof to said mixture of step (a), wherein the ratio of reducing sugar to said compound is in the range of 200-300:1; (c) heating said mixture to a temperature in the range of 90° to 105° C.; and thereafter (d) cooling said mixture to room temperature.
Claim 3
Dependent Claim
27 words
The process of claim 1 wherein the said compound thereof is selected from the group consisting of aspartic acid, glutamic acid, asparagine and glutamine and their monoamides.
Claim 4
Dependent Claim
18 words
The process of claim 1 wherein the weight ratio of sugar to concentrated ammonium hydroxide (30%) is 6-8:1.
Claim 5
Dependent Claim
23 words
The process of claim 1 wherein the reducing sugar is selected from the group consisting of fructose, glucose, mannose, galactose and mixtures thereof.
Claim 6
Dependent Claim
16 words
The process of claim 1 wherein the weight ratio of sugar to said compound is 235-245:1.
Claim 7
Dependent Claim
34 words
The process of claim 1 wherein the reaction flavor product is cooled by diluting with water, said water being added in an amount sufficient to effect a 1-5:1 dilution of the reaction flavor product.
Claim 8
Dependent Claim
22 words
The process of claim 1 wherein heating is continued for 5 to 15 minutes after the temperature reaches 90° to 105° C.
Claim 9
Dependent Claim
11 words
A reaction flavor product prepared by the process of claim 1.
Claim 10
Dependent Claim
26 words
A smoking composition comprising a filler material selected from tobacco, reconstituted tobacco, non-tobacco smoking substitute and mixtures thereof, and the reaction flavor product of claim 8.
Claim 11
Dependent Claim
30 words
The smoking composition of claim 9 comprising a filler of blended tobaccos having incorporated therein between about 0.5 to 10% by weight of the filler of the reaction flavor product.
Claim 12
Dependent Claim
47 words
The smoking composition of claim 9 comprising a filler of tobacco, reconstituted tobacco and tobacco stems wherein tobacco stems comprise up to 50% by weight of the filler and said stems have incorporated therein up to 5% by weight of the stems of the reaction flavor product.
Claim 13
Dependent Claim
33 words
The smoking composition of claim 9 comprising a filler of a non-tobacco smoking substitute having incorporated therein between about 0.5 and 10% by weight of the smoking substitute of the reaction flavor product.
