## Abstract

A method of manufacture of a breadcrumb coating for a food product provides a crumb with an extremely low moisture content without the need for substantial energy input. The method achieves such very low moisture content without significant adverse effect on product quality.

## Claims

### Claim 1

A method of manufacture of a crumb, the method comprising:
extruding a dough composition comprising flour, a gelling agent, optional further ingredients and water to form an extruded composition, wherein the gelling agent is uniformly distributed throughout the composition;
drying the extruded composition in a rotary dryer to form a dried composition, wherein the water content of the dried composition is from about 0.1% to about 1.5% by weight; and
milling the dried composition to form a crumb with a water content of about 0.1% to about 1.5% by weight.

### Claim 2 (depends on 1)

The method of claim 1, wherein the rotary dryer comprises an inlet; an outlet; a passageway for the extruded composition, the passageway extending between the inlet and outlet;
one or more drying units comprising a perforated cylindrical tube extending between the inlet and outlet and a screw extending axially of the tube, wherein one of the tube and the screw are rotatable to move extruded composition from the inlet to the outlet; and means for circulating drying air through the passageway.

### Claim 3 (depends on 1)

The method of claim 1, wherein the crumb has a water content from about 0.3% to about 1.0% by weight.

### Claim 4 (depends on 3)

The method of claim 3, wherein the crumb has a water content from about 0.5% to about 1.0% by weight.

### Claim 5 (depends on 4)

The method of claim 4, wherein the crumb has a water content from about 0.5% to about 0.6% by weight.

### Claim 6 (depends on 1)

The method of claim 1, wherein the crumb has a maximum dimension from about 0.1 mm to about 5 mm.

### Claim 7 (depends on 1)

The method of claim 1, wherein the gelling agent is a hydrocolloid.

### Claim 8 (depends on 1)

The method of claim 1, wherein the crumb contains from about 0.06% to about 4% by weight of the gelling agent.

### Claim 9 (depends on 7)

The method of claim 7, wherein the crumb contains from about 0.08% to about 3% by weight of the gelling agent.

### Claim 10 (depends on 9)

The method of claim 9, wherein the crumb contains from about 0.1% to about 3% by weight of the gelling agent.

### Claim 11 (depends on 1)

The method of claim 1, wherein the gelling agent is selected from the group consisting of natural gums, modified gums, gelatin, pectin, alginate, arabinogalactan, agar, carrageenan, furcellaran, modified starch and combinations thereof

### Claim 12 (depends on 7)

The method of claim 7, wherein the hydrocolloid is selected from the group consisting of natural gums and combinations thereof

### Claim 13 (depends on 12)

The method of claim 12, wherein the natural gum is selected from the group consisting of guar gum, locust bean gum, gum arabic, tragacanth, gum karaya, gum ghatti, xanthan gum and combinations thereof.

### Claim 14 (depends on 1)

The method of claim 1, wherein the extruded pellets are dried in the rotary dryer by employing a counter current stream of hot air having a temperature in the range of 120° C-160° C.

### Claim 15

A crumb, comprising:
milled farinaceous particles of an extruded composition comprising flour;
a gelling agent uniformly distributed throughout the crumb; and
optional further ingredients;
wherein the total water content of the crumb is from about 0.1% to about 1.5% by weight.

### Claim 16 (depends on 15)

The crumb of claim 15, wherein the crumb has a water content from about 0.3% to about 1.0% by weight.

### Claim 17 (depends on 16)

The crumb of claim 16, wherein the crumb has a water content from about 0.5% to about 0.6% by weight.

### Claim 18 (depends on 15)

The crumb of claim 15, wherein the crumb has a maximum dimension from about 0.1 mm to about 5 mm.

### Claim 19 (depends on 1)

The method of claim 1, wherein the gelling agent is a hydrocolloid.

### Claim 20 (depends on 19)

The crumb of claim 19, wherein the crumb contains from about 0.06% to about 4% by weight of the gelling agent.
