Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing tofu, and more specifically, silken tofu that has been coagulated in a coagulation box is cut as it is and heated to produce a tofu that does not lose its shape. The present invention relates to a tofu production method that can efficiently produce silken tofu that has a long shelf life.

[Prior Art] Silken tofu is so named because its appearance and texture are smoother than that of firm tofu, and its cross section is fine and beautiful, like egg tofu. Silken tofu is tofu made by hardening soy milk into a gel-like state, and the water in the soy milk is put into a mold box and hardened with a coagulant without dehydration. In this way, silken tofu solidifies the soy milk into a gel-like form by applying agar to the agar, so the soy milk itself is made quite thick, and the soy milk is quickly and vigorously stirred. is added. In any case, silken tofu coagulated in this way is made from soy milk that is solidified into a gel-like state, so it is not dehydrated and pressed like firm tofu, so it is softer and loses its shape compared to firm tofu. Although it is easy to handle and requires careful handling, and requires intense stirring, it is coagulated in a mold box, so unreacted soymilk and coagulant inevitably remain, making the tofu taste bad.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems such as silken tofu easily losing its shape and being soft, and the coagulant remaining unreacted. To provide a method for producing silken tofu which reacts an unreacted coagulant and can obtain silken tofu that is strong enough not to lose its shape when handled after being taken out of a mold box.

[Means for Solving the Problems] As a result of intensive research into the method for producing silken tofu, the present inventors have found that in order to further harden the coagulated tofu and completely react the unreacted coagulant, The present invention was completed based on the new discovery that further heating of the cooked tofu is extremely effective.

That is, the method for producing silken tofu of the present invention,
a step of injecting soymilk together with a coagulant into a coagulation box to coagulate tofu, a step of cutting the tofu coagulated in the above step into a predetermined size while keeping it in the coagulation box, and putting the cut tofu into the coagulation box. The gist is that it consists of a step of placing the liquid in a heating pot and heating it.

[Effect] By the process of coagulating tofu in the coagulation box,
Soy milk coagulates and becomes silken tofu. Next, in a cutting step, the tofu in the coagulation box is cut into predetermined dimensions while still in the coagulation box. Subsequently, in the tofu heating process, the tofu is placed in a heating pot while remaining in the coagulation box. This heating causes the unreacted coagulant to completely react with the soy milk, making the tofu firm and firm.

[Example] Examples of the present invention will be described to clarify the effects of the present invention.

Soybean milk 12, which had been stirred with a coagulant added by a soybean milk coagulator (not shown), was poured into a coagulation box 10 shown in FIG. 1 and coagulated to produce tofu. Coagulation box 10
After the tofu 12 inside is sufficiently coagulated and aged,
As shown in FIG. 1, an edger 16 is formed by bending the wire 14 into a U-shape according to the inner dimensions of the coagulation box 10.
was inserted into one end of the coagulation box 10, moved to the other end, and pulled up, thereby separating the tofu 12 adhered to the coagulation box 10 from the coagulation box 10.

FIG. 2 is a perspective view of the tofu cutter 18, in which plates 20 are assembled in a grid pattern and a handle 22 is attached to the plate 20 so as to obtain a desired cutting size.
This tofu cutter 18 is inserted into the coagulation box 10 containing the tofu 12 as shown in FIG.
Tofu 12 was cut into predetermined dimensions in a vacuum cleaner.

The heating pot is as shown in the side cross-sectional views of FIG. The water is ejected and the water injected into the heating pot 24 is brought to a boil. Further, a lifting platform 30 is arranged to move up and down from above the heating pot 24.

A coagulation box 10 containing cut tofu 12
As shown in FIG. 4A, the coagulation box 10 containing the tofu is placed on a lifting platform 30, and as shown in FIG. immersed in water. After heating for an appropriate time, the lifting table 30 was raised again, and the tofu 12 placed in the coagulation box 10 was taken out from the heating pot 24 to complete the heating of the tofu.

The breakage rate was investigated for silken tofu produced by the method of the present invention and conventional silken tofu that was not heated at all after solidification. Conventional silken tofu had a breakage rate of about 3% from manufacture to sale, but the silken tofu of the present invention had a breakage rate of 0.

In this example, the tofu was heated by immersing it in boiling water, but the heating method may be steam, and any heating method may be used.

[Effects of the Invention] As explained above, the present invention further heats the silken tofu coagulated in the coagulation box to completely react the unreacted soybean milk remaining in the tofu with the coagulant. In addition, it is possible to obtain strong silken tofu that does not easily lose its shape even after being removed from the coagulation box and handled after the tofu is tightened. Furthermore, since the tofu is cut and heated while it is still in the coagulation box, a large number of tofu can be heated at once, which improves work efficiency.
