Description

 The present invention relates to a cooking sheet for cooking.

  When cooking meat and seafood with broth or water, like boiled food and soup, persimmons float on the surface of the broth during cooking. Aku sometimes absorbs ingredients with a strong taste and smell of candy, and is often removed as an obstacle to the taste, texture and appearance of dishes. In addition, oil generated at the same time as cooking is also avoided in terms of taste and health, and oil that solidifies white particularly on the top surface of a cold dish significantly impairs the appearance of the dish.

For this reason, a disposable cooking sheet using a non-woven sheet and also having a function of removing oil and oil has been proposed.
However, in the cooking sheet, the octopus oil is adsorbed on the lower surface of the sheet, but the octopus oil is not efficiently adsorbed on the upper surface of the sheet because the sheet is difficult to come into contact with the broth.

Then, the cooking sheet provided with the several valve | bulb formation part formed by penetrating from the upper surface to the lower surface of the nonwoven fabric sheet which has a lipophilic fiber, and the valve part formed by this valve | bulb formation part is proposed (patent document) 1).
In the cooking sheet, when the broth was boiled, it blew up from the valve forming part to the upper surface of the sheet, so that oyster and oil could be adsorbed on the upper surface of the sheet.
Japanese Patent No. 3269810

However, in the cooking sheet described in Patent Document 1, it is difficult to adsorb the persimmon that tends to accumulate near the inside of the side surface of the pan (hereinafter referred to as “inner side surface”). Sticking, it was very difficult to wash the pot after cooking.
In addition, in cooking in a pot such as a hot pot that is eaten while cooking, the top surface of the pan must be covered with a cooking sheet each time to remove the perspiration and oil generated each time the ingredients are added. In addition, the cooking sheet becomes an obstacle, so that it is not suitable for such pan cooking. In addition, when the cooking sheet is folded and pinched with chopsticks, the contact area with the broth becomes small, so it has to be turned over and changed, making it difficult to use. Furthermore, a pan cooking sheet formed by stacking two or more sheets has been proposed, but the manufacturing process of the sheet is complicated.

  The present invention has been made in view of the above circumstances, and efficiently adsorbs persimmon oil and is excellent in perspiration that accumulates on the inner surface of the pan, and even when used in a folded state, An object of the present invention is to provide a cooking sheet having a large contact area.

In order to solve the above-mentioned problem, the cooking sheet of the present invention is a cooking sheet made of a substantially circular nonwoven fabric, and the nonwoven fabric projects toward the main body and the outer peripheral side of the main body. The nonwoven fabric has a bending resistance of 1 to 20 mN · cm, and at least a part of the nonwoven fabric is composed of hydrophobic fibers.
Here, the floating portion is formed by providing a plurality of cuts having a length less than one half of the radius from the outer peripheral portion of the substantially circular nonwoven fabric toward the central portion. Is preferred.
The non-woven fabric has a density of 0.01 to 0.10 g / cm ³ , a basis weight of 20 to 80 g / m ² , a thickness of 0.5 to 2.0 mm, a single oil absorption time of 2 seconds or less, and The nonwoven fabric is preferably entangled with short fibers by hydroentanglement treatment.
Furthermore, it is preferable to provide two or more intersecting cuts at the center of the nonwoven fabric.

  According to the present invention, there is provided a cooking sheet that efficiently adsorbs persimmon oil and oil, is excellent in adsorbing persimmon accumulated inside the pan, and has a large contact area with the broth even when used in a folded state. Can be provided.

Hereinafter, the present invention will be described in detail.
FIG. 1 is a top view showing a cooking scraping sheet (hereinafter referred to as “scraping sheet”) 1 according to the present embodiment.

The punching sheet 1 of the present invention comprises a substantially circular nonwoven fabric 10 as shown in FIG. 1, and the nonwoven fabric 10 is provided with a main body portion 11 and a floating portion 12.
The floating portion 12 is provided so as to protrude toward the outer peripheral side of the main body portion 11, and has a plurality of outer peripheral cut portions having a length less than a half of the radius from the outer peripheral portion 13 of the nonwoven fabric 10 toward the central portion 14. 15 is formed.
Here, the floating part 12 is a floating piece that moves up and down so as to wave against the main body part 11 in accordance with the movement of the boiled water surface.

Moreover, the bending resistance of the nonwoven fabric provided with the main body part 11 and the floating part 12 is 1 to 20 mN · cm. More preferably, it is 2-15 mN * cm, More preferably, it is 4-9 mN * cm. When the bending resistance is within the above range, the floating portion 12 moves up and down as if it undulates with respect to the main body portion 11 due to thermal convection caused by heating of the gas stove. For this reason, the air that accumulates on the inner surface of the cooking pan is well adsorbed on both sides of the floating portion 12 and prevents the perspiration from sticking to the inner surface of the cooking pan. As a result, cleaning of the cooking pan after cooking becomes very easy. . Moreover, since the broth or the like can be easily contacted even on the upper surface of the sheet, the adsorption on the upper surface of the persimmon oil is promoted.
In general, the bending resistance of a nonwoven fabric can be adjusted by appropriately selecting the material and thickness of the short fibers used in the nonwoven fabric, the entanglement method and the degree of entanglement between the short fibers. In addition, the bending resistance of the nonwoven fabric described here refers to the bending resistance and the lateral bending resistance of the nonwoven fabric measured according to the slide method (bending softness method) described in JIS L 1096 “General Textile Testing Method”. It is a value represented by the average of the direction bending resistance.

  Furthermore, it is preferable that the cutting sheet 1 of the present invention includes two or more intersecting center cut portions 16 in the center portion 14 of the nonwoven fabric 10. By providing the center cut portion 16, when the cooking sheet 1 is folded and picked up with chopsticks or the like when cooking in a pan such as a pot to eat while cooking, the center cut portion 16 as well as the floating portion 12 is used. As both sides can adsorb oil and oil, the contact area with the broth can be increased.

(In the case of a drilling sheet corresponding to a cooking pot having a diameter of 18 to 22 cm)
The punching sheet 1 preferably includes 8 to 20 floating portions 12, and more preferably 12 to 16 floating portions. Moreover, 18-45 degrees is preferable and, as for angle (theta) which the two outer periphery cutting parts 15 which form the one floating part 12, 22.5-30 degrees is more preferable. Note that the angle θ depends on the number of floating portions 12. If the number of floating parts 12 is less than the above range, the floating parts 12 cannot cope with the above-described thermal convection. On the other hand, when the number is larger than the above range, it is difficult to process, and it is difficult to spread when using the scraping sheet 1 that is usually folded and stored.

Moreover, 2-4 cm is preferable and, as for the length W1 of the outer periphery cut | notch part 15, 2.5-3 cm is more preferable. When length W1 is shorter than the said range, the effect of this invention is not fully exhibited when it corresponds to a small cooking pan. On the other hand, if the length W1 is longer than the above range, it is difficult to process, and the floating portion 12 is turned up and folded during cooking, resulting in a decrease in the amount of oil adsorbed as a result.
In addition, it is preferable that the diameter of the cutting sheet 1 is 20 cm corresponding to the diameter of a cooking pot.

  Further, the punching sheet 1 is preferably provided with two or more intersecting center cut portions 16 at the center portion 14, and more preferably two to three. When the number of intersections falls within the above range, when the punching sheet 1 is smaller than the diameter of the cooking pan, the center cutting part 16 can be widened to extend the punching sheet 1 as a whole. If the number of intersections is less than the above range, it is difficult to absorb oil when folding the take-up sheet 1 and picking it up with chopsticks. On the other hand, when the number of intersections is larger than the above range, it is difficult to process, and as described above, it is difficult to spread when using the cutting sheet 1.

  Moreover, 5-9 cm is preferable and, as for the length W2 of the center cutting part 16, 6-8 cm is more preferable. If the length W2 is shorter than the above range, it is difficult to adsorb oil or oil. On the other hand, when the length W2 is longer than the above range, it is difficult to process, and as described above, it is difficult to spread when the cutting sheet 1 is used.

(In the case of a drilling sheet corresponding to a cooking pot having a diameter of 24 to 28 cm)
The punching sheet 1 preferably includes 12 to 24 floating portions 12, and more preferably 16 to 20 floating portions 12. Moreover, 15-30 degrees is preferable and, as for angle (theta) which the two outer periphery cutting parts 15 which form the one floating part 12, 18-22.5 degrees are more preferable. Note that the angle θ depends on the number of floating portions 12. If the number of floating parts 12 is less than the above range, the floating parts 12 cannot cope with the above-described thermal convection. On the other hand, when the number is larger than the above range, it is difficult to process, and as described above, it is difficult to spread when using the cutting sheet 1.

Moreover, 2.5-5.5 cm is preferable and, as for the length W1 of outer periphery cutting | disconnection, 3-4.5 cm is more preferable. When length W1 is shorter than the said range, the effect of this invention is not fully exhibited when it corresponds to a small cooking pan. On the other hand, when the length W1 is longer than the above range, it is difficult to process, and as described above, it is difficult to spread when using the cutting sheet 1.
In addition, it is preferable that the diameter of the punching sheet 1 is 26 cm corresponding to the diameter of the cooking pan.

  Further, the punching sheet 1 is preferably provided with two or more intersecting center cut portions 16 at the center portion 14, and more preferably two to three. When the number of intersections falls within the above range, when the punching sheet 1 is smaller than the diameter of the cooking pan, the center cutting part 16 can be widened to extend the punching sheet 1 as a whole. If the number of intersections is less than the above range, it is difficult to absorb oil when folding the take-up sheet 1 and picking it up with chopsticks. On the other hand, when the number of intersections is larger than the above range, it is difficult to process, and as described above, it is difficult to spread when using the cutting sheet 1.

  Moreover, 5-10 cm is preferable and, as for the length W2 of the center cutting part 16, 7-9 cm is more preferable. If the length W2 is shorter than the above range, it is difficult to adsorb oil or oil. On the other hand, when the length W2 is longer than the above range, it is difficult to process, and as described above, it is difficult to spread when the cutting sheet 1 is used.

(Nonwoven fabric)
The nonwoven fabric 10 preferably has a low density and is provided with appropriate voids. Density of the nonwoven fabric 10 is preferably ^{0.01~0.10g / cm 3, 0.03~0.07g / cm} 3 is more preferable. By setting the density within the above range, the punching sheet 1 has a high permeability, so that the particles before the growth of the drill can penetrate into the voids and be trapped between the fibers. If the density is smaller than the above range, the adsorptivity is reduced. On the other hand, if the density is larger than the above range, permeation into the nonwoven fabric 10 is insufficient and a large amount of permeation cannot be effectively adsorbed.

Further, in order to efficiently adsorb oil to the scraping sheet 1, it is preferable that the one-drop oil absorption time of the nonwoven fabric 10 is 2 seconds or less. If the oil absorption time for one drop exceeds 2 seconds, the oil may remain depending on the amount of oil, which may affect the taste of the dish.
Absorption of a liquid into a fibrous material such as the nonwoven fabric 10 is generally considered to be absorption by a capillary tube. Therefore, if the density of the non-woven fabric 10 is increased, the time for one drop oil absorption will be shortened. However, since the majority of the water is actually water and a small amount of oil is present there, as in the case of boiled dishes, the higher the density of the non-woven fabric 10 Water penetrates into the nonwoven fabric 10 and inhibits adsorption of a small amount of oil. Also from such a viewpoint, it is preferable to set the density of the nonwoven fabric 10 within the above range.
Further, since the one-drop oil absorption time is also affected by the interfacial chemical properties of the fiber surface, it is desirable to avoid the treatment of the nonwoven fabric 10 with an antistatic agent or a hydrophilic agent that lengthens the one-drop oil absorption time.

The thickness of the nonwoven fabric 10 is preferably 0.5 to 2.0 mm, more preferably 0.7 to 1.8 mm. By setting the thickness within the above range, oil can be adsorbed with sufficient space.
Moreover, 20-80 g / m < ² > is preferable and, as for the basic weight of a peeling sheet, 30-70 g / m < ² > is more preferable. By setting the basis weight within the above range, a sufficient amount of perforation can be adsorbed and the nonwoven fabric 10 can be made flexible.

At least a part of the nonwoven fabric 10 is made of hydrophobic fibers. Examples thereof include hydrophobic fibers (synthetic fibers) made from polypropylene, polyethylene, polyester, or the like. These may be used alone or in combination. Moreover, you may mix the hydrophilic fiber (natural fiber) which uses pulp, rayon, etc. as a raw material to the said hydrophobic fiber. In the case of mixing, the content of the hydrophilic fiber is preferably 30% by mass or less and more preferably 20% by mass or less with respect to the nonwoven fabric 10 (100% by mass).
When at least a part of the nonwoven fabric 10 is made of hydrophobic fibers, the cut-off sheet 1 becomes difficult to absorb boiled juice, and can efficiently absorb the cutlet oil.

  Although there is no restriction | limiting in particular about the fineness of the nonwoven fabric 10, The thing in which the density of the nonwoven fabric 10 becomes in the range mentioned above can be used arbitrarily. However, when the fibers are entangled by hydroentanglement as described later, if the fineness is too small, excessive entanglement proceeds and the density tends to increase. On the other hand, when the fineness is too large, the entanglement is insufficient, and the strength of the nonwoven fabric 10 is reduced and hair loss is likely to occur. Accordingly, when the nonwoven fabric 10 is formed by performing hydroentanglement, the fineness is preferably 1.5 to 3 denier, and more preferably 2 to 2.5 denier.

  For the formation of the nonwoven fabric 10, a publicly known method can be used. However, for example, the nonwoven fabric 10 obtained by the melt blow method, the spun bond method, or the like has a tendency that the strength decreases when the density falls within the above range. On the other hand, the nonwoven fabric 10 obtained by a hydroentanglement method or a thermal bond method is preferable because the strength does not decrease even when the density becomes low. In particular, since the hydroentanglement method is a method in which fibers are entangled with each other by a water flow, the non-woven fabric 10 obtained by the treatment method is preferable because the hydrophilic oil component is washed away with water and the hydrophobicity further increases.

  It is desirable to appropriately set the conditions for the hydroentanglement treatment method depending on the fibers used. For example, when the proportion of hydrophobic fibers such as polypropylene is large, it is preferable to set the water pressure higher because the confounding property due to water flow is poor. On the other hand, when lipophilic fibers are included, the fibers tend to be excessively entangled and the density tends to increase, so it is preferable to set the water pressure low.

  The hydroentanglement method can apply various forms of webs, but in the present invention, the nonwoven fabric 10 is preferably made of short fibers in order to increase the entanglement between fibers and to provide flexibility. . The fiber length of the short fibers is preferably 25 to 125 mm, more preferably 38 to 64 mm. If the fiber length is shorter than the above range, the confounding property tends to deteriorate. On the other hand, when the fiber length is longer than the above range, the uniformity of the nonwoven fabric 10 tends to be lowered. Moreover, the fiber in the nonwoven fabric used by the hydroentanglement processing method can also be heat-sealed together using the hydroentanglement method and the thermal bond method. In this case, the strength of the resulting nonwoven fabric is improved and hair loss can be prevented.

  The nonwoven fabric 10 obtained by the hydroentanglement method is excellent in drape and has a very good flexibility, so even when used for cooking with a small amount of boiled juice such as meat potatoes, it easily fits the surface of the food and is efficient. Oil can be adsorbed.

As described above, the punching sheet 1 of the present invention includes the floating portion 12 and moves up and down so that the floating portion 12 undulates with respect to the main body portion 11 due to heat convection caused by heating of the gas stove. As a result, it is possible to effectively adsorb the perforation that tends to stick to the inner side surface, and to adsorb the persimmon and oil even on the upper surface of the perforated sheet 1.
Moreover, since at least a part of the nonwoven fabric 10 forming the scraping sheet 1 is made of hydrophobic fibers, the hydrophobic fibers have lipophilicity, so that the oil permeability into the scraping sheet 1 and adhesion to the fibers And the adsorption amount of oil can be increased.

Further, by setting the density of the non-woven fabric 10 and the one-drop oil absorption time within the above ranges, an appropriate gap can be provided, so that not only the surface of the scraping sheet 1 is adsorbed but also the inside of the scraping sheet 1. Since perforation is permeated and captured even between fibers, perforation can be adsorbed quickly and reliably.
Moreover, since the punching sheet 1 has the center cut portion 16 in the central portion 14, even when the punching sheet 1 is folded and picked with chopsticks or the like, the contact area with the broth can be increased. Gradually oil can be adsorbed on both surfaces of the center cut portion 16.

  Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to these examples.

[Test 1: Various evaluations based on differences in shape of punched sheet, composition of nonwoven fabric and manufacturing method]
<Measurement method>
In Example 1 and Comparative Example 1 below, each characteristic of the nonwoven fabric was measured by the following method.
(density)
About the nonwoven fabric whose area (S [cm < ² >]) is known, weight (W [g]) and thickness (t [mm]) were measured. For the thickness measurement, UP LIGHT DIAL GAUGE (Tester Sangyo Co., Ltd. PEACOOK No. 107) was used, and the thickness of the nonwoven fabric after being left for 10 seconds under a load of 3 g / cm ² was measured to 1/100 mm. . The density (d [g / cm ³ ]) was calculated from these values according to the following formula.
Density (d) = (W × 10) / (S × t)

(Basis weight)
Basis weight was calculated | required based on JISP8124 "Paper and paperboard-Basis weight measuring method". The area of the test piece was 100 cm ² .

(One drop oil absorption time)
The sample and the tool used for the measurement were stored for 24 hours or more in a temperature-controlled room with a temperature of 25 ° C. and a humidity of 65%, and then used for the measurement. The measurement was performed in the above constant temperature room as follows.
A punching sheet cut into a 10 cm square was placed on a petri dish with a diameter of 6.5 cm so as to be horizontal and fixed with a string. Drop a drop of soybean oil (reagent, chemical, Junsei Chemical) from a height of about 1 cm above the sheet surface into the unbroken area in the center of the sheet until the oil is completely absorbed by the sheet (reflection of light from the droplet) ) Until the time is gone. For dropping the oil, a Komagome pipette having an outlet diameter of 1.9 mm was used, and the weight of one drop of oil at that time was about 0.03 g. The measurement was performed 5 times with one surface facing upward, and 5 times with the opposite surface facing upward, and an average value of 10 times was obtained, and this was taken as a drop-absorption time.

(Flexibility)
In accordance with the slide method (rigid softness method) described in JIS L 1096 “General textile test method”, the bending resistance (mN · cm) when the test piece length (L [cm]) is 10 cm is the vertical direction and the horizontal direction. For each of these, the average value in the vertical direction and the horizontal direction was calculated. Note that W (mN / cm ² ) is the gravity per unit of the test piece, and σ (cm) is the scale reading (deflection of the test piece).
Flexibility (mN · cm) = WL ⁴ / 8σ

<Example 1-1>
(Manufacture of punched sheets)
Using only polypropylene short fibers (2 denier, 51 mm), non-woven fabric (flexibility 7.4 [mN · cm], basis weight 51.0 [g / m ² ], thickness 1.1 [mm] by hydroentanglement method ]) And was formed into a disk-like sheet having a diameter of 20 cm. According to a conventional method, using a punching blade of a predetermined shape, the blade is punched by pressing the blade onto a sheet of a dozen or more sheets. As shown in FIG. A punching sheet having 16 parts and having a length of 7.0 cm and having a central cut portion intersecting the three parts was obtained.
Table 1 shows the bending resistance, density, basis weight, thickness, and single drop oil absorption time of the nonwoven fabric.

(Evaluation 1: Measurement of total adsorbed amount of steam and oil)
Using a stainless steel cooking pot having a diameter of 20 cm and a depth of 11 cm, meat potatoes for 4 persons were cooked in accordance with “365 days side dish encyclopedia (Housewife's friend company)”. Before punching, a sheet of punching was placed in the pan and lightly pressed to cook. After cooking, the sheet was taken out, and the total adsorbed amount of oil and oil adsorbed on the sheet (sheet adsorbed amount) was obtained from the following equation. Table 1 shows the average of the above repeated 5 times.
Sheet adsorption amount [g / sheet] = (sheet after cooking [g / sheet]) − sheet before cooking [g / sheet])
In addition, the sheet | seat after cooking is a thing which evaporated the water | moisture content of the sheet | seat for 90 minutes at 105 degreeC.

(Evaluation 2: Evaluation of residual feeling of drill and oil)
After cooking, the meat potato broth was observed and visually evaluated for the remaining feeling of citrus oil. The evaluation criteria are as follows. Table 1 shows the average evaluation scores of three professional panelists.
4 points: There is almost no residual feeling, and the broth is very clear.
3 points: Very little residual feeling and clear broth.
2 points: There is a little residual feeling, and the broth is slightly cloudy.
1 point: Akuya oil remains in large quantities, and the broth is cloudy.

(Evaluation 3: Evaluation of dirt removal from cooking pot)
After cooking the meat potatoes, the pan was emptied and left for 10 minutes. Thereafter, the detergent was not used, and only the commercially available sponge (Scotch Bright s-21K, manufactured by Sumitomo 3M Co., Ltd.) was used to rub the pan with a force of 500 gf, and the dirt on the inner surface of the pan was removed. The degree of dirt removal in the sponge width (7 cm) portion was visually evaluated. The results are shown in Table 1. The evaluation criteria are as follows.
4 points: Rub on the sponge surface and the stains are removed within 10 times.
3 points: Rub on the sponge surface and the stains are removed within 20 times.

[Test 2: Use for hot pot dishes (various evaluations based on differences in the shape of the punched sheet)]
<Example 2-1>
A cooking scrap sheet was produced in the same manner as in Example 1-1. Various evaluations were performed as follows.
In a stainless steel cooking pot having a diameter of 20 cm and a depth of 11 cm, 800 ml of water and 200 g of pork shredded meat were placed and heated on medium heat for 10 minutes. The punched sheet was folded and pinched with chopsticks, and the floating oil and drill were brought into contact with the punched sheet and absorbed.
The total adsorbed amount of steam and oil was determined in the same manner as in Example 1-1. Further, the remaining feeling was evaluated in the same manner as in Example 1-1. The results are shown in Table 2.

<Example 2-2>
A cooking scraping sheet was produced in the same manner as in Example 1-1, except that it was punched into the same shape as in Example 1-2. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

<Comparative Example 2-1>
A cooking scraping sheet was produced in the same manner as in Example 1-1 except that it was punched into the same shape as in Comparative Example 1-1. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

<Comparative Example 2-2>
A cooking sheet was produced in the same manner as in Example 1-1, except that it was punched into the same shape as in Comparative Example 1-2. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

<Comparative Example 2-3>
As shown in FIG. 6, 16 straight cuts (length 2 cm) are distributed radially from the center of the sheet (ie, no floating portion is formed), and two straight cuts ( A cutting sheet for cooking was produced in the same manner as in Example 1-1 except that punching was performed so that the length was 7 cm perpendicular to the center of the sheet. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

<Comparative Example 2-4>
As shown in FIG. 7, Example 1 except that punching was performed so that semicircular valves were distributed over the entire surface of the sheet so as to be point-symmetric with respect to the center of the sheet and to be oriented in the same circumferential direction. In the same manner as in No. 1, a cooking scraping sheet was produced. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

<Comparative Example 2-5>
As shown in FIG. 8, the cooking corner sheet is formed into a substantially rectangular shape with rounded corners, point-symmetric with respect to the center of the sheet, and inferior arc shape on the front surface of the sheet so as to be oriented in the same circumferential direction. A cooking scraping sheet was produced in the same manner as in Example 1-1 except that punching was performed so that the valves were distributed. Each evaluation was carried out in the same manner as in Example 2-1. The results are shown in Table 2.

As can be seen from Tables 1 and 2, since the drilling sheets of the examples were able to use the entire sheet effectively, all of them had a large total amount of oil adsorbed, which was not good for cooked dishes. And almost no oil remained. Moreover, the cooking pot was easily washed after cooking. In addition, since the perforated sheet obtained in Example 1-4 had a length of the outer peripheral cut portion of 6.0 cm, the perforated sheet in the pot was turned over several times when performing the evaluation 1, Each time, the original sheet was returned to the expanded state.
On the other hand, all the cut-off sheets of the comparative examples had a small total amount of oil adsorbed, so that the remaining food remained in the cooked dishes.
