CONSERVATION

Food Conservation

In addition to knowing how to buy, it is vital to know how to conserve the food we take home, to prevent them from breaking down, and that bacteria that are in them proliferate, endangering family health.   For this we have to know some fundamental techniques for food preservation, such as: Refrigeration, freezing, salting, smoking and not least thawing in order to preserve the nutritional quality and the organoleptic characteristics of food as they are, the color, smell, texture and flavor of them, thus prolonging their “shelf life”.

Conservation by Refrigeration.

It is one of the cold food preservation techniques, which consists in placing the food in the refrigerator at a temperature of 3-5 degrees C (Celsius or Celsius), for a short period of time, before cooking them. or its subsequent freezing, thus delaying the proliferation of bacteria in these.

When cooling, it must be taken into account that:

  • For the conservation of fresh food in the refrigerator, glass containers usually produce more moisture and tend to rot, so it is advisable to use plastic or Styrofoam containers, wrapped with plastic wrap or vinyl (many foods already come in these packages).
  • The use of metal containers should be avoided, since they tend to reduce the “shelf life” of fresh food inside the refrigerator, because more moisture is produced.
  • Processed foods are best preserved in glass containers, so as not to alter their taste.
  • Foods processed with salt should not be stored in metal containers, because there are some metals that release toxic substances to the body in contact with salt.
  • The refrigerator works best when it is not overly full, so you must calculate the amount of products to buy, so that there are spaces for the cold air to circulate evenly inside it.

Conservation by Freezing.

It is one of the most used and most effective methods for the conservation of cold foods. It consists of subjecting the food to temperatures of less than 0 degrees C (Centigrade or Celsius), which is the freezing temperature of water. Here by freezing cold, bacteria that break down food are inhibited in such a way that their “shelf life” is prolonged. For this method the freezers of the refrigerators are used, programmed at temperatures below 0, or if you prefer and there is enough space at home, you can obtain an additional freezer.

Some guidelines or tips to freeze:

  • Refrigerator freezers work much better when they are full.
  • All foods, both raw and processed, must be properly packed so that the cold does not burn them. Raw foods such as meat, fish and seafood can be packed in plastic bags or vinyl paper (film). The processed can be frozen in plastic containers with lid (never glass to avoid accidents, because the low temperatures can break).
  • Before freezing the food that has been prepared, it should be left to cool, since the temperature of the freezer can go down and as a consequence, decompose the food already frozen. The refrigerator also consumes more energy by having to re-regulate the temperature it lost.
  • Do not freeze food that has already been thawed, to avoid the proliferation of bacteria.

Defrosting

Thawing should be done inside the refrigerator, never at room temperature, to avoid the proliferation of bacteria. The food is taken out of the freezer and placed in the refrigerator the night before so that it thaws. If you forget, you can place the package in a container with drinking water at room temperature and leave it in the refrigerator to thaw. To defrost processed foods, you can use the microwave oven by pressing the defrost button. This is not so convenient for raw meats or fish as they can start their cooking unevenly and activate the microorganisms in them. When defrosting meats, fish or seafood, they should be consumed in their entirety. They should not be refrozen. In fact, no defrosted food has to be refrozen, because the bacteria have been activated and can turn into toxic foods, harmful to health.

Salting or drying.

It is known as salting or drying, the oldest conservation method used by man to preserve some foods, microorganisms (bacteria) that break them down. It consists of using salt in large quantities with the addition of nitrates, to sprinkle with this mixture, meats and fish, in order to slow down its decomposition. They are put to air currents, without the direct sunlight, to lose moisture, as it is an effective means for the proliferation of bacteria.

Smoked.

Smoking is a method of food preservation, which consists of using flaming aromatic woods, exposing food to the smoke of these, to preserve them, giving them flavor and aroma. According to the food, the wood of the tree that best suits itself is chosen. Any hard wood, free of resin (apple tree, oak) and other than pine, cypress, eucalyptus and any red wood is used.

Frozen Products

Frozen Products

Nutritional properties of frozen products.

The freezing process affects very little the nutritional value of food. Currently in the frozen products market, the ultrafreezing technique is used, which according to experts guarantees 100% of the nutritional content. Food should be frozen quickly and at temperatures reaching-40 º C. In this way, the most of its nutritional properties are preserved, also some of the organoleptic qualities (flavor, texture, color and smell), because usually these are altered a little, especially their texture and flavor, except in the raw meats. In fresh foods, the loss of nutrients they may experience since they are collected until they are prepared, may be equal to or greater than alterations during freezing. Then frozen foods in a safe and adequate way are of great nutritional value.

Texture of frozen products.

Freezing all foods should be done immediately and harvested or prepared. They must be frozen without alterations and in unbeatable conditions, that is to say at the moment of optimum quality. If the freezing technique is carried out properly, it guarantees excellent qualities of the food, while a bad freeze implies a significant loss of nutrients, taste and texture. Very different is the home-made frozen, because by not being able to apply or not to have the right technology, the fresh foods that freeze, they can lose quality in terms of nutrients, texture, smell and original flavor.

Buying Frozen products.

To check the status of frozen products to be purchased on the market, you must:

  • Analyze if they are in suitable cooling cabinets, which maintain constant freezing temperatures.
  • packages, be they vegetables, fish, shellfish or empanadas, must have their contents hard and loose.

The gasket should not have frost, so it is known that the cold chain has not been broken. That the product is not in a block or difficult to separate, as it may contain water or happen that there has been a partial thawing and has been frozen again. Do not buy products if they have soft or thawed areas. The gaskets must be intact, new without tears or waste.

  • The date of packing and expiration, expiration or expiration should be looked at. that have not been covered, erased or changed.

Buy the most distant date to be fulfilled. It is possible that frozen foods do not reach our freezer in its optimum conditions, because during the journey the cold chain can break and, in this case, the qualities of the product are altered. It is advisable to leave for the end the purchase of the frozen ones and place them in a thermal bag for their transport and to immediately put them in cold when they arrive at their destination.

Insidence of defrosting in the quality characteristics of the product.

In order to be successful in the preparation and service of frozen food, keep in mind that the manufacturer’s defrosting instructions on the packaging are carefully followed by the letter and slowly. If it is not done correctly, you can risk the product losing its quality (texture, flavor, aroma, color, etc.). If they are frozen food at home, they should be placed first to defrost in the refrigerator (refrigerator) and then take them to cooking. It may also happen that the freezing time has exceeded 6 months or the year, which can also alter its organoleptic characteristics and even more if the procedure has been done at home.
