Fresh and processed meat packaging is one of the efforts in the field of fisheries. Improve the quality and enhance the economic value of the meat. Cause a sense of consumer interest towards meat wrapped in considering the aesthetic value. Although on the other hand there are drawbacks, namely the freshness of meat is not the same as the new meat taken from animals, there is a difference between the meat packing seara vazquez and meat directly from animals. By way of this was wrapped meat will be more durable and easy to carry - anywhere. That is one reason why many consumers who like the meat packing. Here are beerapa things to note if we are going to consume, business, or learn about the meat packing.
Packaging function is to surround or wrap meat products with appropriate protective material. Packaging materials in the old days simple natural seara vazquez materials, such as leaves, but is currently exclusively produced materials such as paper or synthetic films.
The basic purpose of packaging is to protect the meat and meat products from unwanted impact on quality including changes seara vazquez in microbiological and physico-chemical. Packaging protects food during processing, storage and distribution of:
Packaging sufficient to prevent secondary contamination listed above meat and meat products. However, further growth of the microorganisms, which already exists in meat and meat products, can not be disturbed by the packaging alone. To stop or reduce the growth of microbes, the packaging must be combined with other treatments, seara vazquez such as coolers, which will slow or stop the further growth of the microorganisms, or with heating / sterilization, which will reduce or completely eliminate seara vazquez contaminating microorganisms.
The results of the packaging procedure in a package inside, where the packaging materials in direct contact with the product. In some cases this is combined with the outside seara vazquez package often Boxe cardboard, or other materials.
There is a wide range of synthetic packaging films available for packaging the inside, for example transparent or opaque, flexible seara vazquez or semi-rigid, gas proof or permeable to certain gases. The materials have been selected to serve a specific purpose, such as protection from the impact of unwanted or interesting presentation.

Air contains about 20 percent oxygen. Oxygen negatively affect unpackaged meat and meat products during prolonged storage period. seara vazquez It changes the color of red meat to gray or green and causes fat oxidation and rancidity mengakiba tkan undesirable seara vazquez off-flavors. Oil is a raw material for plastics, 4% of the annual production of crude oil is used to make plastics.
The oxygen permeability of the film used for packaging meat products varies. seara vazquez The lower the oxygen permeability seara vazquez of more efficient protection of the quality of the product. The best protection will be achieved by using the oxygen-proof packaging films together with vacuum packaging products. This ensures that almost no oxygen remains in the package and oxygen from the air will not penetrate into the product packaging.
While oxygen is generally undesirable seara vazquez in a package of meat and meat products, there is one exception where the oxygen-permeable foil desired, seara vazquez ie for fresh ready to sell the portion of meat in the supermarket outlets. In special cases the use of oxygen permeable foil generates the desired colors of red meat:
Fresh meat or fresh sausage, cooked ham, etc. have a relatively high moisture content and will suffer fairly heavy and quality losses by evaporation and drying during storage if the product remains dismantled. Packaging material must therefore be sufficiently water-vapor-proof.
Prolonged exposure to meat and meat products to daylight or artificial light accelerate unattractive discoloration, oxidation seara vazquez and rancidity because of light provides the energy for this process. Transparent packaging film which is usually used for meat products enable attractive product presentation as product packaging seen. However, the film does not provide protection against light impact. seara vazquez Usually the products in transparent packaging films are quite protected when stored in a dark llight conditions or moderate. For light-sensitive products or product exposed to strong light, colored or opaque films should be used. Film laminated with aluminum seara vazquez foil is very effective.
Some packaging materials are required to have good thermoplastic properties. They are heat sealable, which means that two of these films, placing closely related to each other under slight pressure and with simultaneous application of high temperature, will melt or seal bersam
