Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet used for baking and steaming foods.

[0002]

2. Description of the Related Art When finishing food by baking or steaming, if the food is simply placed on a supporting plate (tray, wire mesh, etc.), the baked or steamed food will stick to the supporting plate and Not only will it be troublesome to handle, but the product value will be significantly reduced. Therefore, in general, a glassine paper is used as a base material and a sheet having one surface coated with silicon is laid on the support plate such that the coated surface is on the upper side, and food is placed on the sheet. Baking treatment and steaming treatment were performed. When such a sheet is used, the silicone imparts releasability and water repellency, so that the sticking of the food can be suppressed.

[0003]

However, when the above-mentioned sheet is used, since the glassine paper as the base material has almost no air permeability, in the case of baked food, the heating efficiency of the contact portion with respect to the sheet is low, On the other hand, in the case of steamed food, steam does not circulate in the contact portion with the sheet, and unevenness occurs depending on the portion in the finish of the food, which makes it difficult to obtain a sufficiently satisfactory quality. Although some measures have been taken to solve the above-mentioned problems by making a large number of small holes in the sheet (see, for example, Japanese Utility Model Laid-Open No. 63-94999), such a measure indicates that the sheet is In addition to the additional work required for making holes in the holes, there is a certain limit to the number of holes that can be opened due to strength restrictions, and the heating efficiency and vapor permeation effect become insufficient, There was a problem that it was not possible to take fundamental measures.

The present invention has been made in view of the above problems. An object of the present invention is to provide air permeability without performing secondary processing by using a new base material instead of glassine paper. It is possible to provide a sheet for food processing, which makes it possible to make a great contribution to the improvement of the finished quality of food.

[0005]

In order to achieve the above object, the present invention uses a non-woven fabric composed of 100% cellulose fibers as a base material, and coats all or part of the fiber surface of the base material with silicon. It is characterized by being configured.

[0006]

According to the food processing sheet constructed as described above, since the nonwoven fabric made of 100% cellulose fiber is used as the base material and the surface of the fiber is coated with silicon, sufficient heat resistance, peeling property, and release property are obtained. In the water retention,
Sufficient air permeability can be imparted, and not only the heating efficiency in the baking process can be improved, but also the uniform steaming in the steaming process becomes possible. Moreover, since the air permeability of the non-woven fabric is utilized, special secondary processing for imparting air permeability becomes unnecessary.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show a first embodiment of the present invention. In both figures, 1 is a non-woven fabric as a base material, and is composed of 100% cellulose fibers 2. Then, the entire surface of the cellulose fibers 2 constituting the non-woven fabric 1 is coated with silicon (the coating portion is indicated by diagonal lines). The non-woven fabric 1 is manufactured by utilizing the self-adhesiveness of the fiber itself without including a binder at all, and is commercially available, for example, from Asahi Kasei Kogyo Co. under the trade name of Benliese. The method of coating the surface of the cellulose fibers 2 with silicon is arbitrary, for example, a dipping method of dipping the entire nonwoven fabric 1 in a silicone liquid, a coating method of spraying or brushing the nonwoven fabric 1 with a silicone liquid, or printing. The law etc. can be adopted.

In the seat configured as described above,
Since the nonwoven fabric 1 used as the base material is composed of 100% of the cellulose fibers 2, the carbonization decomposition temperature of the cellulose (2
Since it has heat resistance up to 60 to 300 ° C., it can sufficiently withstand the baking treatment of food. By the way, in the case of a non-woven fabric containing a resin binder or a non-woven fabric made of synthetic fibers, the heat resistance of the resin is about 150 ° C. at most, and therefore it cannot be used for baking food. In addition, this sheet is composed of the cellulose fibers 2 constituting the nonwoven fabric 1.
Since the surface of is coated with silicone, its releasability and water repellency are no different from those of conventional sheets (glassine paper coated with silicon), and it can be fully utilized as an underlay for baked and steamed foods.

Moreover, since the nonwoven fabric 1 has sufficient air permeability, it is possible to prevent overheating during the baking process and also to perform uniform steaming during the steaming process, thus improving the finished quality of the food. Furthermore, it is possible to reliably prevent the food from sticking to the food due to overheating, and to avoid the generation of wrinkles due to the variation in the contact area with the steam, which enables repeated use of this sheet and reduces the food processing cost. It is reduced as much as possible.

Using this sheet and a conventional sheet as an underlay for frozen pizza, baking was performed at 180 ° C. for 3 minutes in the oven. As a result, when the conventional sheet was used, Burning unevenness was observed on the side in contact with the sheet, and image sticking was observed on the sheet itself, but when using this sheet, no such abnormalities were observed. Also, using the same sheet and a conventional sheet as an underlay of frozen Shoumai and steamed bun, as a result of performing steaming treatment by Muro, as a result of using the conventional sheet, the food has uneven steaming on the side in contact with the sheet. Recognized,
In addition, wrinkles due to steam were observed on the sheet itself, but no abnormalities were observed when this sheet was used.

FIG. 3 shows a second embodiment of the present invention. The feature of the second embodiment is that the nonwoven fabric 1
The silicon coating layer (hatched portion) 3 is formed on only one-half the depth on one surface side, and the cellulose fibers 2 on the other surface side are at the point where the cloth is exposed. With such a structure, the other surface of the non-woven fabric 1 has a water absorbing property and water retaining property peculiar to the cellulose fiber 2. Therefore, by wrapping the food with the other surface as the inner side, the freshness of the food can be maintained for a long time. It can be held for a long time and can be used as a so-called dreep sheet. Of course, since the one surface side on which the silicon coating layer 3 is formed has releasability and water repellency, it can be effectively subjected to baking treatment and steaming treatment as described above.

4 and 5 show a third embodiment of the present invention. The feature of the third embodiment is that
The point is that a silicon coating layer (hatched portion) 3 is formed on the non-woven fabric 1 in a dot pattern. With such a configuration, the silicone coating layer 3 imparts releasability and water repellency, and the fabric portion (white portion) of the cellulose fiber imparts water absorbability and water retention. It can be used as an underlay for baking and steaming, or as a dreep sheet, and its utility value is further increased.

[0014]

As described in detail above, according to the food processing sheet of the present invention, the nonwoven fabric made of 100% cellulose fiber is used as the base material, and the fiber surface is coated with silicon. Desired heat resistance, peelability,
While ensuring water repellency, sufficient air permeability can be imparted, and baked foods and steamed foods can be finished with high quality without unevenness. Further, not only is there no need for special secondary processing for imparting air permeability, but also repeated use thereof is possible, so its utility value is great.
