The bread from the bakery which do not have preservatives will decay or rot quickly than the bread with preservatives.

Since addition of preservatives, increase the acidity of bread, which decrease the rate of growth of mold and it will last longer.

Growth of mold is also depend on the environmental conditions, like warm, humid weather induce growth of molds and cold temperatures reduces it.

For the experiment :-

Take four breads two from the bakery and other two with preservatives.

Place one of each (bakery and preservatives) on a open plate, it the kitchen.

Place another pair of each type of bread in the refrigerator.
