A meat-packaging procedure and a machine for packaging meat cuts for long-term storage is operated at temperatures of between 28 and 42 F. The process includes sealing meat cuts or full poultry birds or bird pieces within a master bag containing (i) oxygen scavenger materials capable of reducing the residual oxygen content of the atmosphere within the bag to 0 ppm within 96 hours of sealing, and (ii) a CO2 generator capable to generate CO2 in the amount of at least 100 mL per pound of meat or poultry within 7 days of sealing. Gas is injected into the master bag to form a CO2-rich storage environment of at least 50% CO2. For meat trays containing meat with poor color stability, oxygen scavengers are preferably placed within the meat trays. For cuts with good color stability, the oxygen scavengers may be placed outside the meat trays.

Habesha dried food product is prepared according to the steps of: selecting ingredients from at least one of a major food group, an accessory food group, and a whole grain; cooking the selected ingredients according to a Habesha cuisine to result in a form of food; partially dehydrating and freeze drying the freshly prepared form of food to result in segmented dried form of food; or directly freeze drying the freshly prepared form of food to result in powdered dried form of food; and packaging the dried form of food in moisture resistant containers to result in packaged Habesha dried food product. Dried food thus prepared results in less digestive discomfort, shortened food preparation, reduced objectionable smell, and stable products requiring no refrigeration.

In accordance with the present invention there is provided a method for deoxygenation of a first liquid, which method comprises contacting said first liquid with a membrane, which membrane is on its filtrate side in contact with a second liquid comprising an oxygen scavenger.

There is provided a second method for deoxygenation of a first liquid which method comprises contacting said first liquid with a membrane, which membrane is on its filtrate side in contact with an oxygen-lean sweep gas.

The invention is also directed to an apparatus for carrying out these methods.

The present invention provides a very efficient means to deoxygenate liquids of all sorts, such as CO.sub.2 scrubbing solutions and beverages.

The present invention generally relates to a composite material. In particular, the present invention relates to a composite material comprising a mixture of a plurality of metal particles and a porous silica particle, wherein said metal particles are disposed within the pores of the porous silica particle. The present invention also provides a method for preparing the composite material used as an oxygen scavenger.

Systems and methods for packing solutions for oxygen-sensitive articles such as food, beverages, and pharmaceuticals, as well as biological samples and/or cultures are disclosed. In preferred systems and methods, oxygen is removed using a bi-enzymatic reaction sequence that recycles and depletes oxygen to extinction, preferably using an oxidase and a catalase as catalysts and a carbohydrate as co-substrate while at least one the enzymes is in a hydrogel or other polymeric formulation.

Systems and methods for preserving oxidizable substances such as liquids or foodstuffs are disclosed. These systems incorporate a sealing device and an oxygen scavenging chemical or agent coupleable to the system. The oxygen scavenging agent can remove the oxygen from the headspace of a container such as a bottle of wine without reducing the pressure in the headspace to the extent that the flavor of the wine is adversely affected.

A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter an oxygen-rich gas collection chamber. An inlet end of the air pump is communicated with the oxygen-rich gas collection chamber in a controlled manner via a pipeline and a pipeline switching mechanism, for pumping gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that the actual content of oxygen in the freshness-keeping space is in a range of 2% to 19%.
