TECHNICAL FIELD OF THE INVENTION
The present invention provides a container for restoring a dried food for use in restoring a dried food, and a desiccant that can be used repeatedly as a container for restoring a dried food that can easily restore the dried food contained therein. The present invention relates to a food packaging bag.
[0002]
[Prior art]
Conventionally, as a method of restoring dry food, a method of putting dry food in a container, adding water, restoring the dried food by allowing it to stand for a certain period of time, and then pouring the water into a colander or the like to drain the water is common. The method requires a container and a colander, and there is a problem in the equipment used and operability. In addition, a freeze-dried food packaging bag (for example, see Patent Literature 1) in which a predetermined amount of dried food and water necessary for restoring the dried food are vacuum-packaged in a plastic film bag so as to be mixed. Are known. However, in the case of this packaging bag, since the hardness of the preference for restoring the dried food differs depending on the user, it is necessary to enclose the amount of water necessary to restore the dried food to a hardness that meets the preferences of all users. In addition to being impossible, it is technically difficult to make bags with water and dried foods separated so that water can flow into the dried foods.In addition, during transportation and storage of bags packed with water and dried foods, It has the disadvantage that it is very difficult to keep water from flowing into the dried food.
