## Abstract

Sorbic acid-containing powder or granules free from scatterability and rapidly soluble in water consisting of 5-90% by weight of finely divided sorbic acid with particle diameter of 50.mu. or less, 10-95% by weight of an easily water-soluble substance which is a solid at normal temperature and 0-2% by weight of hydrophilic surface active agent, characterized by having particle diameter of 300.mu. or more. The above sorbic acid-containing powder or granules can be obtained by drying after making powder or granules having particle diameter of 300.mu. or more from a mixture consisting of finely divided sorbic acid with particle diameter of 50.mu. or less, an easily water-soluble substance which is solid at normal temperature, water and/or an aqueous organic solvent and optionally, a hydrophilic surface active agent, or by making powder or granules having particle diameter of 300.mu. or more from the dry mixture after drying said mixture.

## Claims

### Claim 1

A readily water-soluble food preservative additive powder or granule composition consisting essentially of 5 to 90% by weight of finely divided sorbic acid having a particle diameter of 50.mu. or less, and 10 to 95% by weight of a normally solid water-soluble material which is an organic acid or a salt of organic acid wherein said powder or granules have a particle diameter of 300.mu. or more.

### Claim 2 (depends on 1)

The food additive powder or granule composition of claim 1 containing 0 to 2% by weight of a hydrophilic surface-active agent.

### Claim 3 (depends on 1)

The food additive powder or granule composition of claim 1 wherein said organic acid is a member selected from the group consisting of citric acid, malic acid, tartaric acid, and fumaric acid.

### Claim 4 (depends on 1)

The food additive powder or granule composition of claim 1 wherein said salt of organic acid is a member selected from the group consisting of sodium and potassium salts of acetic acid, citric acid, malic acid, tartaric acid, fumaric acid and sorbic acid, and monosodium glutamate and sodium inosinate.

### Claim 5 (depends on 1)

The food additive powder or granule composition of claim 1 wherein said sorbic acid comprises 20 to 80% by weight and said normally solid water-soluble material comprises 20 to 80% by weight of the composition.

### Claim 6 (depends on 1)

The food additive powder or granule composition of claim 1 wherein the sorbic acid has a particle size 30.mu. or less, and said powder or granules have a particle size of 300.mu. to 1500.mu..

### Claim 7 (depends on 1)

The food additive powder or granule composition of claim 1 containing 0.5 to 1% by weight of a hydrophilic surface-active agent which is a member selected from the group consisting of cane sugar fatty acid esters, lecithins, fatty acid esters or sorbitan, and the reaction product between sorbitan fatty acid esters and polyoxyethylene.

### Claim 8 (depends on 1)

A method for preserving food products which comprises adding to the food products a food preserving amount of the readily water-soluble food additive powder or granule composition of claim 1.

### Claim 9 (depends on 6, 8)

The method of claim 8 wherein the readily water-soluble food additive powder or granule composition of claim 6 is added to a food product which is a member selected from the group consisting of pickles, wine, fish sausage, meat sausage, jam, mayonnaise, margarine, dog food, and cat food.
