Bacterias.
2 differents types of bacterias :
Aerobics bacterias (living with oxygene)
Anaerobics bacterias ( living without oxygene)Vacuum or M.A.P (with other gas than oxygene) reduce the development of aérobics bacterias inside the productVacuum or M.A.P has no effect on Anaerobics bacterias !
For these reasons

Cold chain .
You need cold storage, because aerobics bacterias are not killed with vacuum but just asleep……
You need cold storage to limit Anaerobics bacterias development and particularly the development of spores…..
You need cold storage to avoid bacteria to convert histidine to histamine

Bacteria.
Pathogenics bacterias are dangerous for health, but also non Pathogenics bacterias are numerous in the fish flesh and contribute to the fast alteration of the
product.
Vacuum and M.A.P Packaging bring solution to reduce these risks.

Rule 1 : Shelf-life depend from freshness of the fish !
Two main factors are contributing to the fish quality sploliation :
1.Time after Fishing.
2.Storage temperature.
Time : Ideal is to process and pack as soon as the fish die !
Temperature : Near 0° celsius as sooon as it is catch, is the must… every grade over play against !

Rule 2 : Shelf-life depend of stress of the fish !
By Catch……
Many fish dies in the nets by fighting to escape…
Other dies on the boat board or in the ice pond……
Stress of the fish just before dying create a high concentration of toxines in the muscles….
And these toxines have a great power of alteration of the meat
It’s result a lost of shelf-life you can mesure in…..days !

Rule 3 : Shelf-life depend of the rigor-mortis phasis
Pre-rigor phasis, is the time between the fish die and the time it’s muscles are becoming hard !
During this phasis, the fish had still it’s immuno-defenses actives and avoid the development of bactérias
Processing and packaging during this phasis increase the shelf-life

Vacuum
This process consists of removing themaximum possible amount of air with avacuum pump, so as to go towards totalevacuation. The aim is to obtain anexcellent level of conservation of food-stuffs; the absence of air in contact withthe product very clearly reduces thedevelopment of aerobic bacteria, which
is the cause of premature ageing of fish
Since the pressure of the air inside thepackaging is almost non-existent, theexternal atmosphere will exert a pres-sure of about 1 kilogram per cm2 on thepackage.
package, deformation of the product, orperforations if the product has sharp-edged parts (e.g. lobsters). For presen-tation purposes, it is common to insertthe vacuum product into a cardboardbox with a window, thus covering thepackage while allowing the product tobe seen.

Vaccum Packaging in Fresh fish
In fresh fish:
Vacuum packaging does not bring a very longer shelf-life than traditional wraping packaging.
One of the main reason is the development of histamine and ABVT
We will always prefer to use M.A.P (see reasons after).
There are some exceptions for shell (mussels by exemple)

In processed fish:
Cooked, cured, smoked or marinated fish can be vacuum packed, having a longer shelf-life than a traditional packaging but also longer than with MAP.

What is Sous Vide cooking
Sous vide is a process by which ingredients are sealed in a pouch under vacuum, and subsequently cooked at a series of precisely defined temperatures to reach a desired result. This gentle cooking method has proven to be a remarkable tool of innovation for a growing number of leading chefs, and continues to grow in popularity.

Modified Atmosphere Packaging
This process consists of removing themaximum possible amount of air with avacuum pump, the absence of air in contact withthe product very clearly reduces thedevelopment of aerobic bacteria, whichis the cause of premature ageing of fish
The higher the level of vacuum in thepackage, the longer the conservation ofthe product. For the majority of products,the residual amount of oxygen in thepackaging should not exceed 0.5% ofthe volume, which is equivalent to a vac-uum pressure lower than 1 millibar.
By re-injecting gas inside the package,the external atmospheric pressure canbe prevented from crushing the con-tents as in the case of vacuum packag-ing. In this way, the product will not besubject to any pressure and will benefitfrom a very attractive presentation and good conservation due to gas specifications

From EUROPEAN COMMUNAUTEE
The Committee therefore concluded that there is no health concern associated with the use of 0.3%-0.5% CO in a gas mixture with CO2
and N2 as a modified atmosphere packaging gas for fresh meat provided the temperature during storage and transport does not
exceed 4°C. However the Committee wishes to point out that, should products be stored under inappropriate conditions, the presence of
CO may mask visual evidence of spoilage.

As we can see, M.A.P is the best technic to have a good shelf-life in fresh fish.
Generally we use a mix of 70% N2 and 30% CO2 but it’s adapted to the type of the fish and also if it’s whole fish or filets
It’s recommended to make tests to obtain a good result in shelf-life, because you have to take in consideration:
- Freshness of the fish ( Catch or Farming)
- Type of fish ( low or high level of fat inside)
- The colour

Specialized companies supply thegases in steel bottles. A gas mixer isneeded to make up the desired mixturecorresponding to the product. The gassuppliers can also provide ready pre-pared bottles of mixture.
The suppliers generally have extensiveknowledge of the mixtures requiredaccording to the products to be pack-aged, and have specialized laboratorieswhich perform tests to determine thesuitable mixture for a product.
In certain cases, such as very large-scale use or mixtures covered by a tradesecret, use can be made of a gas mixerto make up individual mixtures.

• Preservation solution:– Fresh fish: packaging 3 days after fishing at 0-2°C
• Aligal 15 or 60% CO2 + 40% N2
• If C.B.E. risk: 60% CO2 + 10% O2 + 30% N2
– Smoked fish, diced smoked salmon, and surimi: Aligal 12 and 13 at 4°C
– Dried fish: 100% N2 at ambient temperature
• Preservation result:– From 6 days (filets), 8-11 days (whole fish) to 30 days (dried fish)

Comparing Use by Date according to different packaging modes*
• Products tested: mackerel (fatty fish) and whiting (low fat fish) => 1-3 days out of sea, eviscerated and kept under ice
• Temperature conditions: kept at +2°C after packaging• Packagings tested:
– Under air: PSE tray with stretch PVC film– Under vacuum: Vacuum Skin Packaging (VSP) and classic vacuum– Under MAP => several blends; best results with:
• 60% CO2 +40% N2• Film => OPP/ PVDC/ PE (15 cm3 O2/ m2/ 24h)
* Observation between 1 and 11 days of packaging: total volatil basic nitrogen (ABVT), mesophile aerobic flora (FAM), organoleptic test (before and after cooking)
