To start with, let me tell you that the shelf life of food will be extended when it stays away from air, humidity and light. Some foods also need to be stored at specific temperatures and only doing so will keep the same in good condition for longer duration. Remember that packaging food in transparent containers does not protect it from light. So when you use one of the following containers and in case you opt for a transparent piece, do store it in dark, so as to preserve its quality.
