Will something grow mold faster in a closed bag or open bag?

Question

By something I meant bagles.

Answer 1

just put the bagels in the fridge they'll last longer

i don't think closed or open bags have much of an effect on bread's mold

you should worry about the temperature of the environment - if it's really hot, bread will grow mold faster  

Answer 2

Bacteria and food-born illnesses need 6 things to grow: F.A.T T.O.M.

Food, to grow, food-borne microorganisms need nutrients, specifically proteins and carbohydrates, most commonly found in meat, dairy products, poultry and eggs.

Acidity, because microorganisms typically do not grow in alkaline or highly acidic foods, such as crackers or lemons.

Temperatures between 41 degrees F and 135 degrees F are optimal for growth. This is known as the temperature danger zone. Refrigeration does not necessarily kill microorganisms. Food must be handled very carefully when it is thawed, cooked, cooled, and then reheated, because it is in and out of the temperature danger zone multiple times.

Time is what microorganisms need to grow. Bacteria can double their population in twenty minutes. If food is left in the temperature danger zone for four hours or more pathogenic microorganisms can grow to levels high enough to make someone ill.

Oxygen, some require it to grow, and a few require a lack of it. Pathogens that grow with out oxygen can occur in cooked rice, untreated garlic and oil mixtures, and foil wrapped baked potatoes that have been temperature abused.

Moisture, most require water to grow, so they grow well in moist food.

So, if you left a bagal in the fridge not wrapped, it will grow mold faster.

Hope this helps!

Once there is a mold spore on your bagel it is easier for it to grow if the air is stagnant.
