In recent years, various edible films have been developed with diversification of eating habits or improvement of food processing techniques. In particular, techniques such as flavoring, flavoring and coloring have been improved, and the variety of eating habits using edible films has been further promoted. Along with this, the range of uses of edible films has been expanded, and furthermore, development of edible film materials having various flavors, textures and appearances is expected.

Traditionally, there are various foods that use edible or edible coatings such as yuba, wonton, spring rolls, gyoza, drawstring wrapped ingredients in oil fried food, and yuba rolls wrapped with yuba ingredients. . These are means for utilizing the characteristics of the coating film well, eating the film itself in order to taste the texture of the coating film, and capturing ingredients that are easily dispersed during cooking or eluted in the cooking liquid. Is used as a coating.

On the other hand, a method for producing an edible film of soybean protein which is industrially mass-produced with respect to a traditional coated food (for example, JP-A-60-156354) is also proposed.

However, most of these coatings are opaque,
When eating foods using these coatings, especially packaged foods in which the ingredients were captured with the coating, it was not possible to visually confirm the ingredients and eat while enjoying and tasting the color or shape. . In general, the taste of food is not determined solely by the taste of the tongue, but is determined by the combination of the odor sensed by the sense of smell, the texture / texture as texture, and the color / shape felt visually. It is said. However, because there is no suitable edible film with high transparency, most foods wrapped with ingredients are not known what is in them, and are eaten without visual confirmation of the ingredients. It was the current situation.

Conventionally, polysaccharide-based films such as oblate have been commercially available as edible films having high transparency, but they are soluble in water during cooking and are not suitable as edible films used for cooking. In addition, even if it is insoluble in water, it must have strength suitable for cooking and must not be broken during cooking, and furthermore, it must be available relatively inexpensively as a food material. It has been extremely difficult to obtain a transparent edible film that can be used as a coating material for food wrapped with an edible coating.

In particular, since the above-mentioned water insolubility is an essential requirement, it is not possible to use a material such as an oblate which is soluble in water even if it has high transparency. Therefore, a soybean protein film that becomes water-insoluble due to thermal denaturation or the like is noted. However, the conventional soybean protein film has a low transparency, and has a disadvantage that the wrapped ingredients cannot be clearly identified. Therefore, we tried to improve the substantial transparency of the soybean protein film and tried to reduce the film thickness.However, when the film thickness was reduced, the strength was extremely reduced, and especially the strength when wet was significantly reduced. If the ingredients burst out during the cooking process and the coating material jumps out, or if the coating film itself is used for soup, it is difficult to scoop up the coating film with chopsticks, and the film cannot be used.

As described above, since most edible films are used for cooking, sufficient film strength is required when wet, particularly when heated and heated. Therefore, a material that dissolves by wetting is not suitable as a raw material for an edible film, and soy protein that is insolubilized by heat denaturation or the like is most suitable for use as a raw material.

However, conventional edible films of soy protein have low transparency, so that not only traditional foods such as fried and yuba, but also edible films of soy protein produced on an industrial scale are sufficiently satisfactory in transparency. Things were not obtained.

In particular, an external force acts on the edible film during cooking or during eating, and a film thickness that can withstand the external force is required. Therefore, a film thickness that can maintain strength enough to withstand an external force is required, and the edible film needs to have such a degree of transparency that the contained ingredients can be identified. For example, when a transparent edible film of soybean protein is used for a purse, a film thickness of at least about 50 μm is required in terms of strength. However, even if the conventional edible film of soybean protein is industrially produced, it contains a large amount of air bubbles, so that sufficient transparency has not been obtained at such a film thickness.

As described above, in the present invention, the raw material and the film thickness are limited, and when the edible film is used as a packaging material, the edible film has transparency enough to make the inclusions distinguishable and has a smooth surface. It is intended to provide a method for producing an edible film.

Conventionally, when producing edible films of soy protein,
In most cases, in order to impart flexibility to the edible film or simplify the process, the solution of the film forming raw material is supplied to the film formation in a state containing bubbles. When trying to obtain a transparent edible film, which is the object of the present invention, the presence of air bubbles has become a major obstacle, hindering improvement in transparency.
The inventors of the present invention have focused on improving transparency by removing air bubbles, and have repeatedly conducted research.However, in order to completely remove bubbles, the cost was high in terms of equipment and operation costs, which was not a profitable result. . Even if the defoaming is performed completely, in the case of the soybean protein solution or the like of the present invention, the soybean protein solution or the like gels before being applied to a smooth surface. In order to prevent this, stirring is continued until the solution reaches the coating step. During this time,
The solution entraps external air, and although the number of air bubbles is extremely small as compared with the conventional edible film, the air bubbles are scattered and the appearance of the edible film is deteriorated, and the commercial value is significantly reduced. I was

Also, after defoaming, even if the stirring to prevent gelation of the protein is performed under the shut-off of the external air, if the stirring does not lead to finer residual bubbles, the resulting edible film Large air bubbles remain and extremely reduce the product quality. This is, for example, even if the edible film transparency and high elongation are satisfied, there is no value as a product, usually,
1 bubble per cm 2 of edible film
If there are two or more, the power as a product is halved.

The present invention performs the defoaming of such a soybean protein solution with simple equipment at low cost, and even if the solution etc. is incomplete defoaming in which bubbles remain, the obtained edible film can be obtained. The object of the present invention is to provide a method for obtaining a material having high transparency and a smooth surface in which almost no air bubbles remain with the naked eye.

That is, the present invention is a solution of incompletely defoamed soybean protein, etc., is vigorously stirred under conditions in which external air is blocked, and most of the remaining air bubbles are refined to have a particle size of 50 μm or less. Thereafter, the edible film is applied to a smooth surface in a film form and dried to obtain a highly transparent edible film which does not feel the presence of bubbles even when dried in an aerated state. In general, when producing edible films of various materials, when dried in an aerated state, even if the air bubbles are finely divided to the extent that it is not easy to observe with the naked eye, the fine air bubbles burst and coalesce during drying,
Alternatively, it often expands and grows into large bubbles, which can be observed with the naked eye, which often lowers the transparency of the film.

However, surprisingly, in the case of the soybean protein of the present invention, by adjusting the air content, an edible film having high transparency was obtained without any expansion of remaining air bubbles, rupture and coalescence, and the like. This is because soy protein has a high gelling ability, gelation starts immediately after applying a solution or the like to a smooth surface, and a skeleton of a protein molecular structure is established in a state containing fine bubbles. At this time, the balance between the force for expanding the microbubbles by heating in the drying step and the force of the film itself for suppressing the expansion with the establishment of the molecular structure is controlled by adjusting the air content. That is, by adjusting the air content to a specific air content or less, an edible film having high transparency can be obtained without expanding bubbles in the drying step.

The defoaming and stirring, and the coated soybean protein paste or solution applied to the smooth surface may be immediately led to a drying step and dried, but gelation may occur due to the low protein concentration of the solution. When the speed is low, it takes time to establish the skeleton of the molecular structure. Therefore, it is desirable that gelation proceeds appropriately and drying is started after a so-called swirling phenomenon occurs.

Addition of fats and oils helps to improve the flavor of the product, but leads to a decrease in transparency, so that the content is preferably 40% or less based on CP.
Saccharides such as glucose, sucrose, dextrin, and starch are useful for adjusting the texture of the coating, but tend to reduce the transparency and strength of the resulting edible film, and its addition is preferably suppressed as much as possible. A humectant or a plasticizer such as glycerin or sorbite helps to impart plasticity, gloss, etc. to the dried product, and is preferably added in the range of 1 to 50% with respect to CP.

Thus, the soy protein paste or solution is defoamed. Defoaming is performed until the air content of the solution or the like becomes 8% by volume or less, more preferably 1% by volume or less. If the air content exceeds 8% by volume, even if the bubbles are refined in the next step of finely dispersing the remaining bubbles, the number of fine bubbles is too large. The edible film after drying remains undesirably due to the formation of pores, resulting in opacity and opacity resulting in a decrease in transparency. When the air content is 8% or less, an edible film is obtained in which fine bubbles slightly expand but do not burst and coalesce, and almost no cloudiness is observed. Further, when the air content is 1% or less, the bubbles are kept fine and no cloudiness is observed due to the balance of the force which is considered to be due to the force of suppressing the expansion of the film due to the molecular structure of the gelled film. A very transparent edible film is obtained.

The air content is degassed to 8% by volume or less (preferably 1% or less). Thereafter, the solution or the like is stirred under the condition of shutting off the outside air to make remaining bubbles fine. The edible film produced from the solution or the like obtained in this manner has a high transparency, and a highly transparent edible film in which no disturbance of the surface and the structure of the edible film due to swollen coalesced bubbles which leads to visual quality deterioration is observed at all. Can be manufactured.

Example 1 100 parts of powdery separated soybean protein (manufactured by “Fujipro-R” Fuji Oil Co., Ltd .; CP in powder is 85%);
After emulsifying 2 parts of an emulsifier and 560 parts of water in a silent cutter and then defoaming (air content: 0.3% by volume) under a vacuum of 60 mmHg, the number of rotations was set to 10,000 rpm with an in-line mixer (manufactured by Ebara Corporation). Stirring was performed to make the remaining air bubbles completely fine, and a soybean protein solution in which almost no remaining air bubbles were observed under normal pressure was obtained. The resulting solution was immediately spread on an endless belt coated with Teflon (trade name) so as to have a thickness of 0.5 mm, and then passed through a room temperature section for 2 minutes and then advanced into the heating section. The heating section consists of a far-infrared ray irradiating section (passing time 30 seconds) and a hot air (105 ° C) drying section (passing time 3 minutes). After passing through the heating section, the coating is dried to about 10% moisture and then continuously. The edible film of soybean protein was obtained by peeling and winding.
