Food and oxygen which method is right

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

i think it is better to not seal it if you are only gonna eat it in a day, but dont bother much with the fridge because there is no oxygen in there anyway

if you want it to last long, seal it

Answer 2

I would think that WHAT you are storing would have a significant impact on the answer.  But in general, I prefer the vacuum sealed method.  You must be sure to cool any hot food before refrigerating to prevent condensation.  If I have a large quantity to store, I'll cool, or let it breath for awhile, then package it in small amounts and freeze.
