Question

why do canned baked beans last longer in a can than in air?

Answer 1

Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.

Answer 2

The branch of science which deals with chemical bonds is called chemistry.

The correct answer to the question is rancidity.

The process of decomposition of the edible items in presence of air which gives a bad odor is called rancidity.

The canned baked items are less prone to rancidity because they have preservation and nitrogen gas in them which prevent them from decomposition.

When the food reacts with the air it starts to decomposition due to oxidation.

Hence, canned baked last longer than the can in the air.
