A container that has growing bacteria must be closed and/or sealed to prevent contamination by other bacteria.
Use a ice-cream container and seal it
yes
rinse container with water seal with top and dispose in garbage
Seal it in a container and put it in the refrigerator.
This is how you spell "seal" in french: seal
yeah as long it is in a container that is 100% seal-able in a carton
couse it is important to there sate seal
When they've finished growing inside them
It affects the food because the bigger the container, the more air gets in it when you seal it.
It does not need to be refrigerated if it is in a sealed container (prior to opening the container the first time). However, when the seal is broken, the jelly can potentially grow mold and bacteria. So, technically, no it does not have to stay cold all the time. But if you are not eating it a relatively short time frame, the jelly develops mold and bacteria contaminants fairly quickly depending on conditions since it is an ideal growing environment (all the sugar). Ideally, colder environments are less conducive to bacterial growth, hence, the reason for putting food in the fridge. But if you wanted to take it on a picnic or something it shouldn't hurt anything.
Good cereal containers include the Sistema's Klip It Cereal Container and both Rubbermaid's Flex & Seal Canister and its Modular 22 Cup Cereal Container.
Depends on pretty much everything: what kind of gas, size of container, pressure, weather or not the seal is airtight, what the container is made of. Next time, try being more specific.
