The present invention pertains to methods of preserving fresh produce with a produce preservative which extends the shelf life of fresh produce, particularly cut fresh produce. The produce preservative preserves the texture, flavor, appearance, crispness, and color of the fresh produce, particularly the exposed surface of the fresh produce. The method comprises the following steps: providing a solution of produce preservative comprising: water, magnesium ions or zinc ions or tin ions; and ascorbate ions, or erythorbate ions; wherein the magnesium ion or zinc ions or tin ions and ascorbate ions are present in a mole ratio of preferably from 0.2:1 to 8:1, more preferably from 0.75:1 to 8:1, more preferably from 1:1 to 4:1, most preferably 1.5:1 to 3:1, applying said produce preservative to the produce; applying said produce preservative to the produce.
A process for preserving fresh produce without adversely affecting the flavor of the fresh produce to any significant degree, the process comprising applying to the fresh produce an aqueous preservative consisting essentially of an anion selected from ascorbate, erythrobate or both and magnesium cations supplied to the aqueous preservative by magnesium hydroxide, magnesium oxide or a magnesium salt other than magnesium chloride, the molar ratio of ascorbate and erythrobate anions to magnesium cations being about 4:1 to 1:1, the aqueous preservative containing sufficient magnesium cations and ascorbate, erythrobate or both anions so that the produce is prevented from browning for at least about 1 week, the aqueous preservative containing no greater than about 0.1 wt % chloride ion based on the weight of the dry ingredients in the preservative, no greater than about 0.1 wt % acid anions other than ascorbate and erythrobate based on the weight of the dry ingredients in the preservative, and no more than about 0.1 wt. % metal ion sequestrant based on the weight of the aqueous preservative as a whole.
