Definitions

  • the present invention relates to a fresh food packaging of the type used to contain and display fresh food products, in particular fresh meat and produce products, providing enhanced shelf-life for the product.
  • absorbent pads have been proposed to be included within the aforementioned package to extend the shelf-life of a fresh food product to be packaged therein.
  • U.S. Pat. No. 4,275,811 and U.S. Pat. No. 4,321,997 to Miller disclose one form of an absorbent pad intended to extend shelf-life of food products in the aforementioned package.
  • the absorbent pad comprises an upper liquid impermeable plastic sheet and a perforated lower plastic sheet with an absorbent mat placed therebetween.
  • the pad is intended to be placed in the package on the tray, the meat product resting on the pad.
  • Liquid exuded from the food product is intended to be absorbed by the pad through the perforations in the lower sheet. In this manner, the liquid is held out of contact from the food product, thereby reducing contamination of the food product and improving its appearance and shelf-life.
  • the packaging of the present disclosure has been found to increase the shelf-life of food products, particularly fresh meat and produce products such as fresh fruit, beyond that provided by the aforementioned packaging by incorporating a separate carrier for one or more food preservatives in the packaging.
  • the packaging of the present disclosure includes a tray pack, a separate carrier for one or more preservatives, and a wrapping material.
  • the separate carrier is an inert sheet coated or impregnated with the preservative(s). It is then intended that the carrier be placed on the upper surface of the tray pack, the food product placed on the carrier having the preservative(s) and the wrapping material placed around the tray pack and food product.
  • An exemplary preservative is a natural preservative, for example, a naturally occurring acid such as citric acid or a salt thereof such as sodium citrate.
  • an absorbent food sheet or pad can be included. If included, the absorbent sheet or pad can be placed on the upper surface of the tray pack, the carrier having the preservative(s) placed on top of the absorbent pad or sheet, the food product placed on top of the carrier, and the wrapping material placed around the tray pack and the food product.
  • a separate carrier in the packaging is in the form of a perforated product tray coated or impregnated with the preservative(s) for placement on the upper surface of the tray pack of the packaging.
  • the product tray includes spacing members for separating its product carrying surface above and apart from the upper surface of the tray pack, allowing liquid exudate from the food product to collect on the tray pack, below the product tray in a manner such that the food product is separated from and is not in contact with the exudate.
  • the product tray is removable from the package, allowing the food product placed thereon to be removed from the package without having to touch the food product.
  • the product tray being perforated further allows for the food product to be easily and conveniently rinsed prior to preparation and cooking, for example, by placing it and the food product under a water faucet or in the case of seafood in a cold water bath.
  • the product tray can be included with the aforementioned inert carrier sheet in the food packaging and, optionally, further including an absorbent sheet or pad.
  • the product tray may also be included in the packaging without being coated or impregnated with one or more preservatives.
  • a packaging insert is provided in the form of either or both a carrier sheet or a food product tray having one or more food preservatives for use in packaging for food products.
  • the carrier sheet having the preservative(s) may be offered and sold separately as a food packaging insert for use in packaging including a tray pack and optionally an absorbent food sheet or pad.
  • the product tray may also be offered and sold separately, with or without preservative(s), or together with the other packaging components.
  • a method for packaging a fresh food product is also provided in which the packaging of the present disclosure is used to package and display the fresh food product, providing extended shelf-life for the food product and/or additional convenience in handling the food product.
  • FIGS. 1-4 Many aspects of the disclosed packaging can be better understood with reference to the attached drawings, FIGS. 1-4 .
  • the components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention.
  • like reference numerals do not need corresponding parts throughout the several views.
  • FIG. 1 is a top view of the packaging of the present disclosure including both a carrier having a food preservative and a perforated product tray.
  • FIG. 2 is a top perspective view of the product tray of FIG. 1 .
  • FIG. 3 is a bottom perspective view of the product tray of FIG. 1 .
  • FIG. 4 is an exploded side elevational view of the packaging of FIG. 1 .
  • the packaging includes a conventional tray pack 1 and additionally a separate carrier coated or impregnated with one or more preservatives, in the form of an inert carrier sheet 5 or a product tray 7 or both.
  • a separate carrier coated or impregnated with one or more preservatives in the form of an inert carrier sheet 5 or a product tray 7 or both.
  • an absorbent sheet or pad 3 may be included.
  • An overwrap (not shown) completes the packaging.
  • the tray pack 1 has a bottom wall 11 , side walls 13 , and end walls 15 and is shaped to provide an interior space for receiving a fresh food product 9 .
  • the tray pack 1 can be formed of any material suitable for packaging food products. Such materials include expanded polystyrene, blown polyvinyl chloride (PVC) molded pulp and other formable materials compatible with the food product to be contained within the packaging.
  • the tray pack 1 is made of thermoformed polypropylene, such as those offered by Sealed Air Corporation under the trademark CRYOVAC®Wrap.it.
  • the optional absorbent food sheet or pad 3 can be any of the various absorbent food sheets or pads conventionally available. Examples include those disclosed in U.S. Pat. No. 4,275,811, U.S. Pat. No. 4,321,997 and U.S. Pat. No. 5,176,930, which are incorporated herein by reference as if fully set forth.
  • the separate carrier is in the form of a carrier sheet 5 and can be made of any material compatible with the food products intended to be contained in food packaging. Additionally, it is desirable that the carrier material be non-reactive with the preservative(s) it carries.
  • the carrier sheet 5 is made of polystyrene film or non-woven polypropylene sheet material.
  • Carrier sheet 5 is coated or impregnated with one or more preservatives.
  • exemplary preservatives are naturally occurring preservatives that serve to maintain a desired pH level within the package. We have found that, by maintaining the pH level of the food product at or below 6.9, the growth and migration of pathogens, such as bacteria, that cause decomposure of, for example, fresh meat and produce products, is inhibited. Thus product shelf-life is extended beyond that provided by conventional packaging that does not include our sheet coated with the preservative.
  • the carrier sheet 5 is a four mil polystyrene sheet coated with one or more natural preservatives.
  • natural preservatives include naturally occurring acids such as citric acid and acetic acid, salts thereof such as sodium citrate and phosphoric acetate, anhydride forms thereof, and mixtures of such acids, salts and/or anhydride forms.
  • citric acid may be preferred over acetic acid because of its more pleasing taste and odor.
  • Phosphoric acetate can be used as a preservative either in place of citric acid or in addition to citric acid.
  • the natural preservative(s) can be applied to or coated on the carrier sheet 5 in the form of a composition including one or more naturally occurring acids or salts thereof and an oxidation reduction agent compatible with the preservative(s).
  • the natural preservative(s) can be in the form of a paste, gel, powder, liquid or solid. When in the form of a paste, gel or liquid a vehicle (such as water) can be included.
  • the preservative is a dried mixture of citric acid, distilled water and a yellow dye applied as a coating on carrier sheet 5 .
  • One or more non-naturally occurring preservatives can be included with the natural perservative(s).
  • the carrier is a product tray 7 included within the packaging of the present disclosure that may be included with our without the carrier sheet 5 .
  • Product tray 7 provides a convenient means for removing the food product 9 from the packaging and rinsing the food product prior to preparation. It also provides a means for placing the food product 9 spaced apart from and above the upper surface of the tray pack 1 . In this manner, liquid that exudes from the food product 9 , in particular a meat product, can drip to the bottom of the tray pack 1 without the product coming in contact with the liquid exudate that collects. If an absorbent food sheet or pad 3 is present, product tray 7 also keeps the pad 3 from sticking to the food product, allowing the food product 9 to be removed from the tray pack 1 without the pad 3 annoyingly sticking to the food product.
  • the product tray 7 may also be made of any material suitable for use with food products such as meat. Suitable materials include expanded polystyrene, blown polyvinyl chloride (PVC), and molded pulp. In an exemplary embodiment the tray is made of thermoformed polypropylene, as well as the tray pack 1 . Further, the product tray 7 may or may not be coated or impregnated with the aforementioned preservative(s) and made of a material that is inert or non-reactive with the preservative(s).
  • product tray 7 is a perforated generally planar structure optionally having opposed thumb tabs 71 .
  • Product tray 7 has a flat, planar, rectangular, perforated upper food product carrying surface 72 , though its upper surface could also be concave, for example, to better hold the food product in place. Further, its surface 72 need not be rectangular. Its surface 72 can be another shape, such as square, oval or elliptical. As illustrated, the perforations provide square shaped openings 73 . The square shaped openings 73 form longitudinal and transverse strips 74 . One skilled in the art would recognize that the openings need not be square and that any other opening shape may be suitable.
  • the openings 73 allow liquid that exudes from the product 9 to fall through the product tray 7 and collect on the tray pack 1 , or if an absorbent sheet or pad 3 is present to be absorbed by it, below and separate from the product 9 .
  • the openings 73 also allow for rinsing of the product 9 after being removed from the packaging while still carried by the product tray 7 .
  • the product tray has a thickness 75 sufficient to provide adequate support for the food product.
  • product tray 7 has a bottom surface 76 that includes spacing members 77 , 78 , such that when the product tray 7 is placed in the packaging the spacing members 77 , 78 serve to separate the food product carrying surface 72 of the product tray 7 from the upper surface of the tray pack 1 , and if present from the upper surface of absorbent food sheet or pad 3 .
  • Exemplary spacing members include feet 77 and/or transverse (shown) or longitudinal (not shown) ridges 78 running along the bottom surface 76 of the product tray.
  • spacing members include feet 77 and/or transverse (shown) or longitudinal (not shown) ridges 78 running along the bottom surface 76 of the product tray.
  • feet 77 and/or transverse (shown) or longitudinal (not shown) ridges 78 running along the bottom surface 76 of the product tray.
  • the wrapping material (not shown) for the packaging can be any conventionally used and available overwrap.
  • An example is Cryovac BDF-2001 film that is a multi-layered, coextruded polyolefin shrink film with good aroma and oxygen barrier properties, offered by Sealed Air Corporation, Duncan, S.C.
  • the overwrap can be a clear plastic film allowing the food product to be seen and displayed in the packaging.
  • a carrier sheet 5 having one or more preservatives may be placed on the upper surface of the tray pack 1 , the food product 9 placed on top of the carrier sheet 5 and the packaging finished by wrapping a wrapping material, such as the aforementioned overwrap, over the food product, around and underneath the tray pack.
  • a wrapping material such as the aforementioned overwrap
  • such packaging may include an absorbent food sheet or pad 3 placed either between tray pack 1 and carrier sheet 5 , or on top of carrier sheet 5 between carrier sheet 5 and the food product 9 .
  • carrier sheet 5 is coated, as opposed to impregnated, with one or more preservatives, preferably the preservative coating is placed on the surface of the carrier facing food product 9 .
  • the packaging consists of product tray 7 placed on the upper surface of tray pack 1 with the food product 9 placed on top of product tray 7 , finished as before with a wrapping material or overwrap.
  • such packaging may include one or both of carrier sheet 5 having one or more preservatives and an absorbent food sheet or pad 3 . If present, carrier sheet 5 or pad 3 may be placed between tray pack 1 and product tray 7 .
  • a packaging system for extending the shelf-life of fresh food products such as fresh meat and produce.
  • a food packaging insert in the form of a carrier having one or more preservatives for extending the shelf-life of fresh food products is provided for use in conventional food packaging.
  • a food product tray for use in conventional food packaging is provided.
