Store your carrots. Before storing, remove the greens, as they will deplete the carrot of both moisture and nutrients. [6] Roll up the carrots in a sheet of bubble wrap (the small textured kind) and place in the vegetable drawer in the fridge. The bubble wrap will enable the perfect amount of moisture to stay close to the carrots, but the texture of the bubble wrap will prevent that moisture from gathering right on the surface of the carrots. If you use a plastic bag, that will lead to rotting. bubble wrap will add up to two extra weeks of freshness to your carrots. It is best to use carrots within one to two weeks, as this will provide you with the best nutrients and taste value.good luck.
