The present invention relates to a method for producing a fried tofu product with the aim of obtaining a fried tofu product having a bright golden brown color. Traditionally, fried tofu products were often consumed within a short period of time, such as on the day of production or the next day, but recently there has been an increase in demand for fried tofu products that have been dried and have a long shelf life. . For these uses, foods that were conventionally fried using rapeseed oil or soybean oil have come to be used in various oils from the viewpoint of storage stability. Many of these oils have relatively high melting points compared to conventionally used vegetable oils.For example, such oils include hydrogenated liquid oils such as soybean oil, rapeseed oil, rice oil, corn oil, and cottonseed oil. Examples include so-called hydrogenated oil and palm oil. Fried tofu products like this,
Fried tofu products that are fried while the oil is still fresh have a whiter fried color than those fried with conventional rapeseed oil or soybean oil, and do not have a beautiful golden brown color, resulting in inferior commercial value. It had the following drawback. In addition, such fried tofu products have a poor appearance compared to conventional products even when seasoned, and have problems such as the fact that fried tofu cannot be processed into Inari sushi or the like. Also, soybean oil, rapeseed oil, rice oil, corn oil,
In order to obtain a deep-fried tofu product with a deep deep color using so-called hydrogenated oil or palm oil, which is hydrogenated liquid vegetable oil such as cottonseed oil, it is necessary to fry the tofu at a higher temperature than usual. As a result, fried tofu products exhibit a brown color, but not only is the color tone dark, but the surface portion becomes hard, making seasoning processing difficult, and the taste when eaten becomes significantly worse. Furthermore, raising the temperature of the oil is not preferable from the standpoint of oil quality control. In order to eliminate these drawbacks or problems, the present inventor has made extensive studies and determined that by adding sugars to soy milk during the manufacturing process of fried tofu products, the temperature of the oil can be adjusted regardless of the type of oil. The present inventors have discovered that a deep-fried tofu product with a bright golden brown color can be obtained at a lower cost than when conventional liquid vegetable oils such as white-squeezed rapeseed oil and white-squeezed soybean oil are used, and have completed the present invention. It came to this. The manufacturing process for fried tofu products is generally as follows. That is, whole soybeans are soaked overnight in 3 to 5 times the amount of water, the soaked beans are ground, and 10 to 12 times the amount of water is added.
Heat to 90℃ to 100℃ for ~5 minutes and immediately add about 5 times the amount of cold water called reconstituted water to the raw soybeans.
The temperature is lowered to 60°C to 70°C, filtered, and okara is separated to obtain soy milk. A coagulant of an alkaline earth metal salt such as calcium chloride is added to this soymilk to coagulate it, a part of the supernatant (called "yu") is removed, and the coagulated product is placed in a mold box and compressed, with a moisture content of approximately 80% Make 90% of the dough. This dough is processed and fried according to the purpose, such as deep-fried tofu, namaage (atsuage), and ganmodo. To explain in more detail the method for manufacturing fried tofu products according to the present invention, during the above-mentioned manufacturing process, the amount of soymilk is It is characterized by adding 0.05 to 0.5% (wt%) of saccharides to the total amount of sugar. Dough containing 0.05% to 0.5% sugar based on the amount of soymilk is fried to give it a brighter golden color tone compared to dough without added sugar, and has a better appearance. Ta. Next, examples of the present invention are shown below. Experiments were conducted by varying the amount of sugar added to the amount of soymilk as shown in the table below.

[Table] The amount of sugar added to the amount of soymilk in the present invention is
0.05% or more and 0.5% or less, preferably 0.08%
~0.3%. If it is less than 0.05%, the change in color of fried tofu products due to the addition of sugars will not be obvious, and if it is less than 0.5%, the skin of fried tofu products will become hard and the color will also darken, resulting in poor commercial value. I'm getting used to it. The saccharide used in the present invention may be either saccharide (molasses sugar, sucrose sugar) or starch saccharide, but starch saccharide is preferable in order to produce a more vivid golden brown color tone. In addition, the manufacturing method for fried tofu products is based on 0.05% of the soymilk amount to soymilk at the specific stage described below.
There is no particular restriction as long as 0.5% sugar can be added. The timing of adding sugars is not particularly limited as long as it is before, during, or after the addition of the coagulant and before compressing the coagulant, but preferably the coagulant,
Preferably before or during addition. The effects of the present invention are that a tofu deep-fried tofu product having a bright golden color tone has been obtained; It is an object of the present invention to provide a method for producing a deep-fried tofu product having a bright golden brown color without making the price particularly higher than when the tofu was fried. Examples of the present invention are shown below. Example 1 16g of refined glucose was added to 16g of soy milk at a temperature of 65℃.
Add the solution dissolved in 100 ml of water, then add the coagulant solution, stir, and coagulate. After solidifying, remove the “yu”, put it in a mold box, compress it, and remove the moisture.
Make a dough with a thickness of 82% and a thickness of 7mm. 50mm of this fabric
Cut into 50mm pieces and spread in a fryer with palm oil at 115℃ for 5 minutes, mustard temperature 160℃.
Fried tofu was carried out at ℃ for 5 minutes. When the finished fried tofu was compared with fried tofu without the addition of glucose, it was found that there was no difference in taste and it had a bright golden brown color. Example 2 A solution prepared by dissolving 32 g of liquid sugar in 100 ml of water was added to soy milk 16 at a temperature of 65° C. together with a coagulant solution, and the mixture was stirred and coagulated. After solidifying, remove the “yu”, put it in a mold box, compress it, and remove the moisture.
Make 85% dough with a thickness of 1.5cm. 50 pieces of this fabric
It was cut into pieces of mm x 50 mm and fried for 2 minutes at 180°C in a fryer containing palm oil. The finished namaage (deep-fried tofu) had no difference in taste and had a bright golden brown color compared to namaage without the addition of liquid sugar.
