Problems solved by technology

But there is such a problem that when the temperature rises again to cause coagulation, it is difficult to best play the original role of bittern in terms of taste and tofu structure, and the operability is not very strong

Embodiment 1

[0019] Add 15kg of water to 5kg of soybeans at 10°C and soak for 14 hours. Use a 10-eye strainer to remove the soaked soybeans. The soaked soybeans were ground on a mill (manufactured by Seisaku-sho Co., Ltd., Nakagawa) together with 25 kg of milling water to obtain soybean paste. Soymilk (solid content: 9% by weight) and okara ("okara") in the soybean paste were separated with a separator (manufactured by Tofer Corporation). The soybean milk was heated at 98°C for 5 minutes with an indirect heating device (manufactured by Hoshitaka Co., Ltd.). Then, the soybean milk was concentrated by heating and reducing pressure (100 mmHg) with a concentrator (manufactured by Seisaku-sho Co., Nichihan) so that the solid content therein became 12.5% ​​by weight.

[0020] Adjust the temperature of soybean milk to 70°C. The slow-acting coagulant "Nigari Meijin" produced by Riken Vitamin Co. was continuously added to the soybean milk at a weight ratio of soybean milk: coagulant=100:0.5 (the...

Embodiment 2

[0028] Tofu was produced in the same manner as in Example 1, except that the slow-acting coagulant "Cho bittern" (product of Riken Vitamin Co., Ltd.) (0.4 parts) was used instead of "Nigari Meijin "Coagulant.

Embodiment 3

[0030] Tofu was produced in the same manner as in Example 1, except that the "Nigari Meijin" coagulant was replaced by 0.8 parts of the slow-acting coagulant in Example 1 of Japanese 2000-032941 A Patent.

[0031] The products of Example 2 and Example 3 not only have a good coagulation state, but also have good shape and taste of tofu. Industrial production

[0032] As described above, according to the present invention, a tofu having a good shape and taste can be continuously and efficiently produced.

Abstract

There is provided a process for producing tofu wherein a delayed action coagulant is dispersed in heated soybean milk in a static inline mixer provided with a narrowed part and then a thickening raw material is added thereto in an inline mixer provided with a dividing element to thereby continuously and efficiently produced a nigari-tofu product being in a good state and having favorable taste.

Description

field of invention [0001] The present invention provides a method for the continuous production of tofu using a so-called bittern-type coagulant. Background of the invention [0002] The most popular traditional method of producing tofu is to add a bittern-type coagulant to soy milk and fill the resulting mixture into a frame. In addition to the traditional brine extracted from seawater, chlorides of alkaline earth metals (such as calcium chloride, magnesium chloride, etc.) can also be used as a brine-type coagulant, and the brine tofu produced is better than sulfuric acid in flavor, taste and texture. Tofu produced by salt-type coagulant (its main component is sulfate of alkaline earth metal). However, due to the high water solubility and high reactivity of bittern-type coagulants, there are many limitations in using this coagulant. Thus in some cases a delayed coagulant is used which is prepared by covering the bittern with a hydrogenated oil or an oily phase. [0003] ...
