Abstract:
A method for blanching vegetable material comprising heat treating the vegetable material in a current of hot air at a temperature in the range from above 100°C to 150°C in an environment which substantially reduces evaporative loss of water from the vegetable material.
Abstract:
A method to imparting color stability and textural stability to strawberries, which can be fresh, or optionally IQF treated. This method comprises several stages including cuticle removal, alkalinization of the fruit pulp, infusion of a soluble stabilizing agent by immersion in an alkaline media to give the necessary firmness and texture integrity, infusion of dyeing agents by immersion in an alkaline color solution, fixation of said color and stabilizing agents in an acidic solution that has been enriched with polyvalent cations, to preserve and extend the shelf life.
Abstract:
The invention concerns a process for decreasing the discoloration of vegetables, wherein
a) the fresh vegetables are submerged in water, b) the obtained mixture with water is degassed, c) said mixture is flushed with nitrogen to bring back the system to atmospheric pressure and d) the treated vegetables are drained and frozen.
Abstract:
Pour améliorer la durée de conservation de légumes et de fruits frais, on soumet des légumes ou fruits épluchés et lavés à l'eau successivement à une désinfection à l'aide d'un agent oxydant (tel que l'eau oxygénée), puis à un traitement à l'aide d'un agent réducteur (tel que du bisulfite de sodium), les produits ainsi traités étant finalement séchés et conservés à une température de 0,5 à 5° C.
Abstract:
Methods of preserving fresh produce with a produce preservative which extends the shelf life of fresh produce, particularly cut fresh produce, and preserves the texture, flavor, appearance, crispness, and color of the fresh produce, particularly the exposed surface of the fresh produce, are provided. The method comprises: providing a solution of produce preservative comprising: water; a preservative cation which is selected from the group consisting of a strontium ion, lithium ion, barium ion, aluminum ion, copper ion, ammonium ion, iron ion, manganese ion, potassium ion, or mixtures thereof; and ascorbate ions, or erythorbate ions; wherein the ascorbate ions or erythorbate ions and the preservative cation are present in an ion ratio of preferably from 0.2:1 to 8:1, more preferably 0.75:1 to 8:1, even more preferably from 1:1 to 4:1, yet more preferably 1.5:1 to 3:1; most preferably 1.1:1 to 2.5:1; and, applying said produce preservative to the produce. The invention also relates to fresh produce preserved with the produce preservatives.

Abstract:
A process for the production of a frozen vegetable or part thereof, wherein said process comprises the steps:
(i) subjecting a vegetable or part thereof to a firming treatment selected from:
a) immersing the vegetable or part thereof in a solution of a calcium salt. b) heating the vegetable or part thereof to a temperature in the range 50 to 70°C, and c) a combination of a) and b);
(ii) under-cooling to a core temperature of less than or equal to -5°C; (iii) reducing the temperature to less than or equal to -18°C.
The frozen vegetables, when thawed, possess a texture and appearance which closely resembles that of fresh vegetables.
