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.

Methods for preserving fresh produce

The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, a releasing material is blended into the polymer so that the releasing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

An oxygen absorber includes an iron powder, and a first layer coated on a surface of the iron powder and formed of iron chloride through a chemical reaction. Further, the oxygen absorber includes a matrix material filled with the iron powder covered with the first layer of iron chloride. It is possible to coat the first layer on the surface of the iron powder with a second layer to obtain more uniform coating.

Oxygen absorber

A process of molding thermoplastic preforms into bottles and similar containers wherein pressurized liquids, such as water, are used in the stretching and shaping process instead of pneumatic gases, such as heated air. The result is greater control over the crystallization of the thermoplastic material and economies of scale. Addition of peroxides, or similar materials are used for sterilization can be added to the liquid thereby conditioning the container for immediate filling with sterile product and eliminating the need for an additional sterilization step following completion of the molding step. As an added step, dry, sterile air can be used to vent and dry the container just prior to introduction of product. Also use of liquid, rather than heated air, provides a washing or cleansing of actealdehydes or ethanol, which may be present in the extruded preform, from the finished container.

The present invention includes a composition having a co-continuous interconnecting channel morphology. These co-continuous interconnecting channels are predominately occupied with a polymer and particles that control the percolation through the composition. The particles are composed of a material such as an absorbing agent, releasing agent and/or activation agent. The polymer composition may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture. The solidified mixture may be used to form plug type inserts and liners for closed containers, or it may be used for producing laminated sheeting employed as package wrap.
