Abstract
A water absorbing article and method of using the same are provided in order to remove drip accumulated at the interface of a food and an water absorbing article and to prevent foods from quality degradation. The water absorbing article comprises a water absorbing sheet comprising at least three layers; a liquid permeable layer made of paper or pulp, a water absorbing layer made of paper or pulp containing water absorbing particles, and a liquid-in permeable layer inserted in between the liquid permeable layer and the water absorbing layer, and the water absorbing sheet is inserted in a bag made of a liquid permeable sheet. The object is attained by placing a food on a liquid permeable layer of the thus-formed water absorbing article and subsequently the whole is vacuum packed. Furthermore, it was also advantageous to prepare a water absorbing article which is prepared by sealing a water absorbing sheet, both surfaces of which have different water absorbing capacities and to apply a method of placing the food on a surface with low water absorbing capacity and vacuum packaging the whole.
