There is a method adopted in one line 1s of the process in No. 48808 and Patent No. 1079790. These methods are
Heat soy milk at a temperature of 700 to 85 degrees Celsius for 10 to 20 minutes,
After that, the soy milk that has gone through this process is held at a temperature of 00 to 45 degrees Celsius for 20 to 80 minutes and then heated to a temperature of 800 to 90 degrees Celsius.
10 minutes, and then heating at a temperature of 122° to 128°C for 1 to 4 seconds (hereinafter, these steps are referred to as sterilization steps).

1にシた。After obtaining the EjiJ patent, the present inventors conducted tests on various spore-forming bacteria using the above-described sterilization process covered in these patents. That is, the persimmon bud 11W bacteria was added to soybean milk, which was then treated through the sterilization process described above, and the survival of the spore bacteria was tested. As a result, it was found that some types of bud fungi were not completely killed in the μl step. Since the spore bacteria are not necessarily present in soy milk, the above sterilization process is sufficient for commercial sterilization.
It was set to 1.
その結果、本発明者らは10℃以下の低温に長時間豆乳

を発見し、本発明を完成した。As a result, the present inventors discovered that keeping soymilk at a low temperature of 10° C. or lower for a long period of time is effective in eliminating all spore bacteria, and completed the present invention.
本発明の目的は、芽胞菌をほぼ完全に死滅させた豆乳の
製造法を提供することにある。An object of the present invention is to provide a method for producing soymilk in which spore-forming bacteria are almost completely killed.
本発明の他の目的は、長時間保存し得る豆乳を提供する
ことにある。Another object of the present invention is to provide soymilk that can be stored for a long time.
更に本発明の他の目的は、長期1u1保イーf L得る
豆腐の製造にも使用できる滅菌され7こ豆乳を提供する
ことにある。Still another object of the present invention is to provide sterilized soybean milk that can be used for the production of tofu that has a long shelf life of 1 μl.

ることを特徴とする滅菌されたり乳の製造法である。In the present invention, soymilk is kept at a temperature of 10°C or lower for at least 10 hours, held at 70° to 80°C for 10 to 2 U minutes, filtered at 00 to 45°C for 20 to 80 minutes, and further maintained at 80°C for 20 to 80 minutes. °
This is a method for producing sterilized milk, which is characterized by holding at ~90°C for 1 to 10 minutes, then boiling and sterilizing by heating.

極めて重要である。The soybean milk used in the method of the present invention is prepared by a conventional method as follows. Wash whole soybeans with water and place them in running water at 5°C.
After soaking for 6 hours and draining, add about 1.9 times the amount of water to the absorbed soybeans, grind with a grinder, etc., steam at 100°C for 4 minutes, and filter out insoluble matter to obtain soy milk. The soymilk thus prepared usually has a pH of 6.6 and a Brix sugar content of 10.5 as measured by a shield meter. The soymilk prepared as described above is maintained at a humidity below io'c for at least 10 hours, preferably at 5° C. for 17 hours. This step of holding the soybean at a low temperature of 10° C. or lower for a long time is extremely important for producing soybean milk.

のが望ましい。The soymilk treated as described above is heat sterilized. Heat sterilization is performed by the same method as for milk sterilization, that is, ultra-high temperature heat sterilization, and is usually heated at 120° to 150°C for 1 to several seconds. However, when sterilized soymilk is used in the production of tofu, it is desirable to heat it at 122° to 128°C for 1 to 4 seconds in view of the curd tension and color tone of the resulting tofu.

らの悪影響も認められなかった。As is clear from Table 1, in this test, a strain that forms strong heat-resistant spores was used, so in the sample obtained by method (■), a large number of spores remained in the sample, which is not a desirable sterilization method. It has been found. Although no residual spores were observed in the sample obtained by method ①, due to the harsh sterilization conditions, the soymilk turned brown and a heated odor was observed. It was found that it decreased. In the sample obtained by method (2), a small amount of spores remained due to the use of particularly heat-resistant spore bacteria, but no adverse effects were observed in the resulting soymilk.

Therefore, it has been found that holding soymilk at low temperatures for a long period of time in the method of the present invention is extremely effective in suppressing the appetite of bacteria that form highly heat-resistant spores.
以上の結果から本発明の方法によって従来の方法よりも

It is desirable that the holding temperature is 10°C or less.

I stored milk. Next, fill this soymilk with 1" acetic acid filling machine manufactured by Tetra Pak Co., Ltd. (
Immediately remove OQml from a sterile filter using AB-300).
A rectangular parallelepiped container was aseptically filled and sealed while being molded to obtain 10019001 times of aseptic soymilk containing tetrabrik. This packaged sterilized soymilk was kept at room temperature for 2 months and then tested using the same method as Test 1. As a result, no bacteria were detected and the product had good color and flavor.

It was added using a bong, and both solutions were mixed in a pipe line. Next, the mixed solution was immediately filled aseptically into a sterile 500 ml container while molding it using a sterile 500 ml container (AB-300) manufactured by Tetra Pak Japan Co., Ltd., and sealed. . Yong? The paper S used was a laminated groove layer laminated in the following order from the top: a polyethylene layer, a paper layer, a polyethylene layer, an aluminum foil layer, and two polyethylene layers. This paper is rolled into a roll so that the lower layer becomes the inner surface, and is formed so that the lower layer becomes the inner surface of the container. The container filled with soymilk was packed in a basket, transferred to a coagulation container at 85°C, heated to coagulate the soymilk in the sealed container, and then left at room temperature to form a sterile soybean container in a tetraderic container.
