A byproduct of microbiotic or enzymatic spoilage can be a variety of gases. That's why containers of spoiled food will swell.
Refrigeration slows microbial growth and does not stop it. So spoilage organisms will still grow - but at a slower rate.
a very long time
An uncooked turkey should be good 1 - 2 days stored in the refrigerator.
Seafood is finicky, i'd say 3 hours.
suprisingly not very long once opened. I think its a week.
3 to 5 days.
Shrimp should be good 1 - 2 days refrigerated.
Chicken spoils quickly and should be cooked within 1 to 2 days of refrigeration.
Just drizzle some lemon juice on it, or it will go brown in seconds.
The refrigerator makes life easier because food spoils. A person can cook a lot of one type of food at one time and put the excess in the refrigerator. Then the person can remove part of the food from the refrigerator and eat it without needing to cook it. Thus, a person, who hates to cook, can even cook once or twice a week and use the refrigerator the rest of the time.
It affects the food because the bigger the container, the more air gets in it when you seal it.
Opened it will not last long before it dries out, but in plastic wrap or a container it will last about 5 days.
All food spoils. Whether it's freeze dried or dehydrated can make it last longer in sealed containers. All food will inevitably spoil. Like your soul.
