Well to find out the answer to that, you need to grab a loathe of bread and cut one slice. Next put it in your mouth, next grab some 'pure' vanilla icecream and put some in your mouth with the slice of bread. Next put about a quarter of cinnamon from the can. Sit outside with still the food in your mouth so the radiowaves from the sun can perserve it. The best place to be is the park if there is one near by. Or for a much easier answer go to lemonparty.org it's an awesome website for students or other people who need help with science. They also have they're own forums to post your questions and staff will answer you.
Food preservation is the process of treating and handling food in such a way as to stop or greatly slow down spoilage to prevent food from getting rotten This can be done in a number of ways, you can coat a food in a substance that will preserve it such as salt, sugar of vinegar. you can dry food or you can keep it in an environment that makes bacteria that degrades food less able to survive such as a fridge or freezer.
Low temperatures, such as refrigeration, slow spoilage since most spoilage organisms grow at a slower rate when they are cold. Freezing stops microbial spoilage because the microbes stop growing.
Airtight containers can significantly slow down the decay of food by limiting exposure to air, which helps reduce oxidation and the growth of mold and bacteria. However, they do not completely stop food from decaying, as some microorganisms can still thrive under certain conditions, and factors like temperature can also affect spoilage. For optimal preservation, it's important to combine airtight storage with proper refrigeration or freezing when necessary.
A byproduct of microbiotic or enzymatic spoilage can be a variety of gases. That's why containers of spoiled food will swell.
Food spoils the fastest between the temperatures of 40oF and 140oF, therefore foods in preparation should not be kept at these temperatures. A refrigerator is below 40oF. bacteria causing food spoilage like to grow about body temperature. As it gets cooler they slow down in reproduction. Freezing stops their growth. Mold also slows at lower temp. A refrigerator slows decay process because it slows the growth rate of spoilage organisms.
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms.Source Wikipedia, 'Food Preservation'.
because there are bacterials that lives in the meat ..the refrigerator slow the grouth of bacterials by the coldness! as u know bacterias need warmness to multiply so the counter is warmer than the fridge!! because there are bacterials that lives in the meat ..the refrigerator slow the grouth of bacterials by the coldness! as u know bacterias need warmness to multiply so the counter is warmer than the fridge!!
Adding perservatives - such as salts or sugars or other chemicals with that fucntion - dry the food up and cause a change in the osmotic gradient which limits the metabolism of the decomposers. Or the cooling down of food, which also limits the metabolism. Heating it up will kill off bacteria and fungi, which are what are responsible for decomposing organic matter.
yes it dose stop it from molding up cold air keep it good...heat make it bad
When the earth cools because it does not have enough radioisotopes left in the mantle and core to keep them hot enough to drive mantle convection.
HEPA filters were invented by the nuclear industry to stop the escape of aerosols of radioisotopes.
4 degrees Celsius - 60 degrees Celsius is the 'danger zone' aka when food spoils. In Fahrenheit, the Temperature Danger Zone is considered 40°F to 140°F. The concern here is actually about growth of pathogens. Spoilage occurs at temperatures cooler than 40°F, as anyone who has cleaned out a refrigerator can attest. Spoilage always has a time-temperature relationship. The warmer it is, the faster it will spoil. Thermophiles can cause spoilage above 140°F, but pathogens don't like that temperature.
