The process of food Conserv mccain micro chips action is the sum of methods that are applied in a particular food that aims to prevent damage or state of decomposition, keeping its characteristics and flavors for short periods of time or longer for human consumption and has the name of shelf life period.
Among all the procedures that have met ing the history of man, the oldest is undoubtedly the salting. Where the salt (NaCl) is the major player in the process, providing dehydration and preserving food for long periods mccain micro chips of time. Who does not know our good noble fish: cod, sold globally in salt form, and also the belongings of the pigs used in both whelks and fantastic jerky and beef jerky. mccain micro chips
All this also includes the time factor, mccain micro chips weather. The dry climate favors the drying process, in Brazil we have this clear in drying coffee, cocoa and other grains mccain micro chips as well, not to mention the nuts from our extensive north and northeast. Corn, beans and soy, are also successful examples of drying to proper conservation and further commercialization. Processes that are performed after the harvest.
Also do not forget to give us bananas bananas passes, figs, oranges pineapples, various fruits we can finally drying by producing candied fruit. In this case, since using the sugars. Also the jam.
And we have another preservative that also happened in history has become an important ingredient in the preparation mccain micro chips of the famous canned. We walked around with the vinegar preparation. In this case, pickles are exemplary best known on the market.
With the evolution of time and research to understand that a good procedure conservation in liquid medium, a supplemental application was necessary to achieve a higher standard of life and quality of food. This was initially applied to milk, it's the pasteurization process, mccain micro chips and was succeeded by a plethora of research methodology and the technique has been applied will largely or most industrialized and also canned to homemade and handmade.
The central focus of these processes is to avoid changes caused by enzymes is specific to products of animal mccain micro chips or plant origin, or natural micro-organisms that, in addition to causing deterioration thereof may produce and release toxins that affect the health of consumers but there is also the concern to maintain the appearance, color, texture, flavor and nutritional content of food.
Well, we have the timeline salt and spices such as rosemary, clove, thyme, basil and basic spices mccain micro chips in the preservation come from ancient Egypt. Even in the process of mummification these elements were found.
Denaturation is a process that takes place in biological molecules, especially in proteins, mccain micro chips when exposed to different conditions of origin, such as variations in temperature, changes in pH, ionic strength, among others. The protein loses its three-dimensional structure and therefore their properties. This is a process which is reversible.
Second case: it is something you learn as "BA-BA" mccain micro chips kitchen, the act of cooking a chicken egg. The heat irreversibly modifies the light, which is formed by the protein albumin and water. You can not return to the clear liquid.
The process also achieves denaturation mccain micro chips of enzymes that perform vital functions in the human body. Why doctors worry before in lower fever than discovering the cause, because the high temperature can destroy enzymes vital functions like enzymes that assist in the breathing process (transport via hemoglobin substance). Are the two sciences, physics and chemistry acting on our body and also in gastronomy.
For many years the terminology pasteurization became public knowledge, and right next to the housewives. Learned to say "I only buy pasteurized milk", but without being aware of what it really meant terminology. It's the old story: "heard the rooster crow, but do not know where." Pasteurize the same as sterilization, a procedure where the factors time x temperature mccain micro chips properly balanced to reach the level of pasteurization or sterilization desired for consumption and having its shelf life established.
- The Pasteurization mccain micro chips - We heat the food to a temperature somewhat lower, with few changes in their properties, and has been recognized as a technique invented by the French chemist Louis Pasteur;
- Sterilization - Already in this case, expose foods to high temperatures for a certain period of time. This time can be long (as in the case of canned food) or too short (IE food
