## Abstract

A solid oral sensorial product includes at least one botanical material and at least one phosphate containing stain inhibitor. The botanical material is selected from the group consisting of tobacco, tea, coffee, cocoa, and combinations thereof.

## Claims

### Claim 1

A method of making a solid oral sensorial product comprising:
mixing at least one solid botanical material selected from the group consisting of tobacco, tea and combinations thereof and at least one phosphate containing stain inhibitor to form a mixture, the stain inhibitor included in an amount sufficient to reduce or inhibit staining of teeth; and
forming a solid oral sensorial product from the mixture,
wherein the at least one solid botanical material and the stain inhibitor are substantially uniformly mixed together and the solid oral sensorial product is selected from the group consisting of oral chews, tablets, moist smokeless tobacco and combinations thereof.

### Claim 2 (depends on 1)

The method of claim 1, further including adding at least one additive to the mixture.

### Claim 3 (depends on 1)

The method of claim 1, wherein the phosphate containing stain inhibitor is added to the mixture in an amount of about 0.001% to about 10.0% by weight based on the weight of the solid oral sensorial product.

### Claim 4 (depends on 1)

The method of claim 1, wherein the forming comprises molding the mixture to form a chew.

### Claim 5 (depends on 1)

The method of claim 1, wherein the phosphate containing stain inhibitor is added to the mixture as a powder and/or as a solution.

### Claim 6 (depends on 1)

The method of claim 1, further including mixing at least one supplemental botanical material other than tobacco, tea and coffee in an amount of about 5% to about 45% by weight based on the weight of the tobacco.

### Claim 7 (depends on 1)

The method of claim 1, wherein the phosphate containing stain inhibitor is selected from the group consisting of calcium hexametaphosphate, tripolyphosphate, and combinations thereof.

### Claim 8 (depends on 1)

The method of claim 1, wherein the at least one phosphate containing stain inhibitor is included in an amount of about 0.001% to about 10.0% by weight based on the weight of the solid oral sensorial product.

### Claim 9 (depends on 8)

The method of claim 8, wherein the phosphate containing stain inhibitor is selected from the group consisting of sodium hexametaphosphate, calcium hexametaphosphate, tripolyphosphate, and combinations thereof.

### Claim 10 (depends on 8)

The method of claim 8, wherein the solid oral sensorial product contains about 25 mg to about 75 mg of the phosphate containing stain inhibitor.

### Claim 11 (depends on 10)

The method of claim 10, wherein the solid oral sensorial product contains about 40 mg to about 60 mg of the phosphate containing stain inhibitor.

### Claim 12 (depends on 8)

The method of claim 8, wherein the solid oral sensorial product weighs about 0.5 g to about 5.5 g.

### Claim 13 (depends on 1)

The method of claim 1, wherein the oral chew further comprises at least one polymer.

### Claim 14 (depends on 1)

The method of claim 1, wherein the tablet comprises botanical powders.

### Claim 15 (depends on 8)

The method of claim 8, wherein the solid oral sensorial product contains about 0.5 g to about 5.0 g of botanical material.

### Claim 16 (depends on 8)

The method of claim 8, wherein the phosphate containing stain inhibitor is sodium hexametaphosphate and the botanical material is tobacco.

### Claim 17 (depends on 8)

The method of claim 8, further comprising at least one coating.

### Claim 18 (depends on 17)

The method of claim 17, wherein the at least one coating comprises at least one phosphate containing stain inhibitor.

### Claim 19 (depends on 18)

The method of claim 18, further comprising applying a coating including at least one phosphate containing stain inhibitor to an outside surface of the solid oral sensorial product.
