The present inventors have found that the present invention is effective for maintaining freshness mainly due to discoloration on the cut surface of cut flowers, and have reached the present invention. That is, the present invention provides a basis weight of 25 g / m 2 or more, a smoothness of 1 second or more,

/ M less than 2, it is inferior discoloration prevention effect of the cut surface of fruits or vegetables, cut flowers when a paper of water absorption below 60%. This is water absorbing
This is presumed to be due to insufficient removal of browning enzyme by paper . Further, even when paper having a smoothness of less than 1 second is used, the effect of preventing discoloration of cut surfaces of fruits and vegetables or cut flowers is inferior. This is also presumed to be due to the fact that the contact area between the water-absorbent paper and the cut surfaces of fruits and vegetables and cut flowers is small and the adhesion is insufficient, so that the adsorption and removal of the browning enzyme is insufficient.

A water-absorbing sheet formed by applying 10 organic acids is more effective. It is presumed that these organic acids suppress the action of browning enzymes. The organic acid having 2 to 10 carbon atoms is preferably selected from food additives from the viewpoint of food hygiene, such as adipic acid, citric acid, lactic acid, tartaric acid, kojic acid, glutamic acid, vitamin C malic acid and the like.

In addition to the usual coating method using a brush or the like, a method of immersing a water-absorbing material in the solution or passing the water-absorbing material through the solution to adhere the solution can also be adopted.

される。The most efficient method for preventing discoloration of fruits and vegetables or cut flowers using the water-absorbent paper of the present invention is to bring the water-absorbent paper into substantial contact so that the cut surface is covered. The term “substantially contact” means that the cut surface is covered to such an extent that the discoloration preventing effect can be obtained, or the entire surface or a part of the cut surface is brought into contact. Specifically, the cut portion is wrapped in the fruits and vegetables or cut flowers with the water-absorbent paper , or the whole fruits and vegetables or cut flowers are wrapped. When the whole is wrapped, not only discoloration of the cut but also wilting, yellowing and decay of the leaves are suppressed, and freshness is maintained.
