US Patent:

20060008558, Jan 12, 2006

Filed:

Jul 8, 2004

Appl. No.:

10/886759

Inventors:

Richard Perdue - Taylors SC, US

International Classification:

A23B 7/148

US Classification:

426106000

Abstract:

A packaged peanut product prepared by providing fresh in-shell green peanuts, boiling the peanuts in a salted hot water bath, air cooling the peanuts after boiling to cool the peanuts to a temperature range of between 100 F. to 175 F., packaging the peanuts into a high gas barrier container when the peanuts are within the temperature range of 100 F. to 175 F., vacuum sealing the container to remove air and seal the container, submerging the container with the peanuts in a cold tap water bath until the peanuts are chilled to the temperature of the cold tap water bath, and storing the container with the peanuts in a refrigerated condition, whereby the texture and flavor of fresh green peanuts can be preserved for an extended period of time by inhibiting enzymatic activity and microbial growth in the green peanuts without artificial preservatives or extensive high temperature pasteurization and processing.

Appl. No.:

10/915671

Inventors:

Richard Perdue - Taylors SC, US

International Classification:

A23L 3/00

US Classification:

426234000

Abstract:

Pasteurizing fresh fruit comprising the steps of slicing whole fresh fruit; treating the fruit slices with an antioxidant; packing the fruit slices into a container suitable for microwaving; vacuum sealing the fruit slices in the container; microwaving the container after vacuum sealing to raise the temperature of the fruit slices; bathing the container with the fruit slices in a hot water bath following microwaving for a period sufficient to inhibit enzymatic activity and eliminated microbial contamination in the fresh fruit; and, bathing the container with the fruit slices in a cold water bath following bathing in the hot water bath to stabilize the fruit slices for storage; whereby the sliced and treated fruit is pasteurized and retained in a fresh condition within the container for an extended period of time without changes in color, texture and flavor to the fruit, and without the use of artificial preservatives.

Appl. No.:

5/499701

Inventors:

Richard Russell Perdue - Greer SC

Assignee:

W. R. Grace & Co. - Duncan SC

International Classification:

B65B 3102

US Classification:

53 22A

Abstract:

The invention disclosed is directed to a new improved apparatus for vacuum skin packaging an article between two flexible web layers. The apparatus includes two molds, each having an inner wall defining a generally concave open cavity and terminating to a lip about the cavity opening, means for receiving and releasing web layers in wall-conforming shape, means for releasably receiving outer portions of the web layers adjacent the lips, means for registering the molds to provide a partially enclosed third cavity, and means for reducing pressure substantially throughout the third cavity by removing gaseous composition therefrom through a passageway means provided by portions of the lips which are spaced apart when the molds are in packaging register. Also disclosed is a process for vacuum skin packaging. If desired, the process may be performed using the apparatus.

International Classification:

US Classification:

53433

Abstract:

In the prior art, vacuum skin packaging processes are performed by placing the product to be packaged on an impervious backing board; placing the product and board in a vacuum chamber; positioning a sheet of thermoplastic film above the product and backing board in the chamber; evacuating the chamber; then, either pulling the film down over the product or pushing the product up into the film; and, thereafter sealing the film to the board. In the present invention, a portion of the film is drawn by differential air pressure against the concave interior surface of the upper portion of a vacuum chamber; the film is then heated by surface contact; and then, after evacuation of the chamber, air pressure is used to blow the film down over the product and against the backing board. Thus, in the present invention, the film is shaped in a concave fashion surrounding the upper portion of the product and it is not necessary for the product to move. The height of the chamber may be adjusted for different products so that excess film is not used and wrinkling is prevented.
