Food storage and oxygen

Question

some food storage container use to have vent (small holes) this type container manufacturing company use to say due to small holes oxygen circulation will be there and food going to get oxygen which is good and some food storage container use to have vacuum inside here theory is most living o****m require oxygen to live so bactaria etc do not going to grow and spoil food which is good. from this two theory which one is right?

Answer 1

No "theory" is ever "right".

It depends on what, where, and for how long you are storing. Grapes come in containers with holes, but you can't leave them for longer than a couple weeks in the fridge. Ground beef is vacuum sealed and can be frozen for up to a year. Salad dressing comes with no holes for obvious reasons, but as soon as you open the jar it must be refridgerated because oxygen has been caught in it, providing ways for the chemicals inside the dressing and the oxygen to react, so cooling it slows down that process.

It really depends, and that's why all scientists and me included say that no theory is correct... they are just theories.
