The present invention relates to a particulate food preservative composition comprising at least 60 wt. % of preservation granules having a diameter in the range of 150-1800 μm, wherein the preservation granules are compacted agglomerates of:

a. particles containing at least 90 wt. % of the chloride salt and
b. particles containing at least 70 wt. % of the alkali metal salt of organic acid, said preservation granules comprising (i) at least 20 wt. % of chloride salt selected from sodium chloride, potassium chloride, magnesium chloride and combinations thereof; and (ii) at least 20 wt. % of an alkali metal salt of an organic acid selected from acetic acid, lactic acid, propionic acid and combinations thereof; the combination of the chloride salt and the alkali metal salt of an organic acid constituting at least 80 wt. % of the dry matter that is contained in the preservation granules.

The preservative composition of the present invention can be used to preserve fresh foods, such as fish, meat and vegetables and is particularly effective against micro-organisms having a high salt tolerance (halotolerant), such as Listeria monocytogenes.
