Abstract
Abstract A method of treating tobacco is described which involves the use of physical force to cause liquid containing catalase and hydrogen peroxide to permeate the interstices of the tobacco where they are reacted with each other in situ. Such reaction enhances properties of the tobacco, and in certain cases the volume of the tobacco is expanded. The physical force necessary to cause the treating material penetration may take the form of rollers, flat pressure means or continous expression means.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A METHOD OF TREATING TOBACCO TO IMPROVE ITS FLAVOR AND EXPAND THE TOBACCO, COMPRISING THE STEPS OF SUBSTANTIALLY EVENLY DIDTRIBUTING ON THE SURFACE OF THE TOBACCO CATALASE AND A LIQUID SOLUTION CONTAINING HYDROGEN PEROXIDE, THE AMOUNTS OF CATALASE AND HYDROGEN PEROXIDE BEING SUFFICIENT TO MUTUALLY DECOMPOSE EACH OTHER, AND BEFORE SIGNIFICANT REACTION BETWEEN THESE TWO COMPONENTS OBTAINING, APPLYING PHYSICAL FORCE IN THE FORM OF PRESSURE MEANS SELECTED FROM THE GROUP COMPRISING ROLLER MEANS, FLAT PRESSURE MEANS, AND CONTINUOUS EXPRESSION MEANS TO SAID TOBACCO TO CAUSE CATALASE AND HYDROGEN PEROXIDE TO PERMEATE THE INTERSTICES OF THE TOBACCO, WHEREBY THE CATALASE AND HYDROGEN PEROXIDE REACT IN SITU ON AND WITHIN THE TOBACCO.
Claim 2
Independent Claim
110 words
A METHOD OF TREATING TOBACCO TO IMPROVE ITS FLAVOR AND EXPAND THE TOBACCO, COMPRISING THE STEPS OF SUBSTANTIALLY EVENLY DIDTRIBUTING ON THE SURFACE OF THE TOBACCO CATALASE AND A LIQUID SOLUTION CONTAINING HYDROGEN PEROXIDE, THE AMOUNTS OF CATALASE AND HYDROGEN PEROXIDE BEING SUFFICIENT TO MUTUALLY DECOMPOSE EACH OTHER, AND BEFORE SIGNIFICANT REACTION BETWEEN THESE TWO COMPONENTS OBTAINING, APPLYING PHYSICAL FORCE IN THE FORM OF PRESSURE MEANS SELECTED FROM THE GROUP COMPRISING ROLLER MEANS, FLAT PRESSURE MEANS, AND CONTINUOUS EXPRESSION MEANS TO SAID TOBACCO TO CAUSE CATALASE AND HYDROGEN PEROXIDE TO PERMEATE THE INTERSTICES OF THE TOBACCO, WHEREBY THE CATALASE AND HYDROGEN PEROXIDE REACT IN SITU ON AND WITHIN THE TOBACCO.
Claim 3
Dependent Claim
35 words
The method in accordance with claim 1, wherein the physical force is removed from the tobacco prior to the completion of the reaction of catalase and hydrogen peroxide, thereby allowing volumetric expansion of the tobacco.
Claim 4
Dependent Claim
22 words
The method in accordance with claim 1, wherein a catalase solution is first applied and then a hydrogen peroxide solution is applied.
Claim 5
Dependent Claim
22 words
The method in accordance with claim 1, wherein a hydrogen peroxide solution is first applied and then a catalase solution is applied.
Claim 6
Dependent Claim
27 words
The method in accordance with claim 1, wherein step (1) comprises applying a liquid solution containing both catalase and hydrogen peroxide on the surface of the tobacco.
Claim 7
Dependent Claim
13 words
The method in accordance with claim 5, wherein the catalase is delayed catalase.
Claim 8
Dependent Claim
13 words
The method in accordance with claim 1, wherein the tobacco is uncured tobacco.
Claim 9
Dependent Claim
13 words
The method in accordance with claim 1, wherein the tobacco is cured tobacco.
Claim 10
Dependent Claim
14 words
The method in accordance with claim 1, wherein the tobacco is whole leaf tobacco.
Claim 11
Dependent Claim
13 words
The method in accordance with claim 1, wherein the tobacco is tobacco lamina.
Claim 12
Dependent Claim
