## Abstract

The invention relates to active dry yeast which is packed in the form of a fermentation agent as a tablet containing active dry yeast.

## Claims

### Claim 1

A fermentation agent tablet comprising active dry yeast, wherein a dry matter content of the tablet is at least 88% by weight, wherein the tablet weighs from 1.0 g to 250.0 g, wherein the tablet further comprises at least one breadmaking improver, and wherein at least 50% by weight of the tablet is the active dry yeast.

### Claim 2 (depends on 1)

The tablet of claim 1, wherein the dry matter content of the tablet is from 90% to 96% by weight and wherein the active dry yeast comprises non-instant active dry yeast.

### Claim 3 (depends on 1)

The tablet of claim 1, wherein the dry matter content of the tablet is from 94% to 97% by weight and wherein the active dry yeast comprises instant active dry yeast.

### Claim 4 (depends on 1)

The tablet of claim 1, wherein 160 mg of the dry matter of the tablet is capable of producing from 20 to 150 ml of CO2 in 2 hours in Test A1.

### Claim 5 (depends on 1)

The tablet of claim 1, wherein 160 mg of the dry matter of the tablet is capable of producing from 20 to 150 ml of CO2 in 2 hours in Tests A1 and A2.

### Claim 6 (depends on 1)

The tablet of claim 1, wherein 160 mg of the dry matter of the tablet is capable of producing from 15 to 120 ml of CO2 in 2 hours in Test A2.

### Claim 7 (depends on 1)

The tablet of claim 1, wherein the tablet weighs from 1.0 to 100.0 g.

### Claim 8 (depends on 1)

The tablet of claim 1, wherein at least 75% by weight of the tablet is the active dry yeast.

### Claim 9 (depends on 1)

The tablet of claim 1, wherein the tablet further comprises at least one ingredient for drying yeast.

### Claim 10 (depends on 9)

The tablet of claim 9, wherein the breadmaking improver is selected from the group consisting of antioxidant agents, reducing agents, enzymes and emulsifiers.

### Claim 11 (depends on 1)

The tablet of claim 1, wherein the tablet further comprises at least one excipient.

### Claim 12 (depends on 11)

The tablet of claim 11, wherein the excipient is selected from the group consisting of polysaccarides, cellulose derivatives, gums, pectins, monosaccharides, disaccharides, calcium phosphate, calcium diphosphate, polyvinylpyrrolidone and polyalcohols.

### Claim 13 (depends on 1)

The tablet of claim 1, wherein the tablet further comprises monosaccharide selected from the group consisting of fructose and glucose.

### Claim 14 (depends on 1)

The tablet of claim 1 further comprising a covering layer, wherein the covering layer forms a barrier against moisture, oxygen or a combination thereof.

### Claim 15 (depends on 1)

A method comprising preparing a dough for a baked product using the fermentation agent tablet of claim 1.

### Claim 16 (depends on 1)

A method of preparing a dough for a baked product comprising mixing the fermentation agent tablet of claim 1 with dough ingredients.

### Claim 17 (depends on 16)

The method of claim 16, further comprising fermenting the dough by the fermentation agent tablet and baking the fermented dough.

### Claim 18 (depends on 1)

A packaging for active dry yeast, the packaging comprising at least one of the tablets of claim 1.

### Claim 19 (depends on 18)

The packaging of claim 18, comprising one or more envelopes, wherein each of the envelopes contains one or more of the tablets and wherein each of the envelopes forms a barrier against moisture, oxygen or a combination thereof.

### Claim 20 (depends on 18)
