Benefits of technology

[0006] The present invention provides a method of packaging, and resulting package that is particularly effective for long time frame shipping and storage of seafood. The method of the present invention results in very low mortality rates over twenty or more days of storage, making the present invention effective for large scale packaging of live seafood species for shipment to inland locations, utilizing low cost transit options.

Problems solved by technology

Bringing live seafood to inland markets can be problematic and expensive.
The most obvious and expensive, way to do so is to expedite transport of the live animals by air, preferably in an aqueous environment simulating their natural environment.
This is effective, but expensive, because of the weight involved.
This method, then, requires additional handling of each item and the use of an additive thereto, and is therefore, not economically feasible.
It has been found to be effective on some shellfish, but as will be discussed below, is ineffective in relatively long time frame shipping and storage.

Embodiment Construction

[0024] In the method of the present invention, seafood, for instance blue mussels (Mytilus edulis) are packaged in modified atmosphere packaging (MAP) having a CO2 / O2 ratio of less than 1:1, preferably less than 1:2, and preferably in the range of 1:4. The packaging method of the present invention is effectively illustrated by the following example.

Materials:

[0025] 1. Eleven bags of 25 lbs. live mussels were harvested on Aug. 13, 2003 from PE3M area and delivered to the testing facility. The temperature reading of the incoming samples was 7.3° C. by using a Fluke Thermometer (5211 with type K thermocouples, Fluke Corporation, USA). [0026] 2. Two types of multilayer high barrier film (OF-900M for forming the trays and OF-475M for sealing, both made of Nylon / EVOH / mpE) sourced from the Packaging Group (Concord, ON) were used. [0027] 3. One cylinder of food grade oxygen and one cylinder of carbon dioxide. [0028] 4.500 mL of 1.5 ppm chlorine dioxide solution.

[0029] Methods: Seven gas...

Abstract

A method of packaging live seafood comprises the steps providing a sealable container placing the live seafood in the container and replacing the atmospheric gas in the container with a gas mixture comprising CO2 and O2 content of at least 50% and a CO2 content of at least 20%.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority to Canadian Patent Application No. 2,489,738 filed Dec. 10, 2004. BACKGROUND OF THE INVENTION [0002] The present invention relates to the field of live seafood packaging. In particular, the present invention provides an improved live seafood packaging method and package that improves mortality rate of packaged live seafood, as compared with know live seafood packaging. [0003] In the marketing of seafood, in particular shellfish, crustaceans and mollusks, it is very desirable to deliver a live product, to permit a restaurant or seafood market to offer the best possible seafood to the consuming public. Bringing live seafood to inland markets can be problematic and expensive. The most obvious and expensive, way to do so is to expedite transport of the live animals by air, preferably in an aqueous environment simulating their natural environment. This is effective, but expensive, because of the weight involve...
