A method of producing packed tofu that is easily released from the container, in which an aqueous ethanol solution or an aqueous solution of a magnesium salt and/or a calcium salt is previously applied to the inside of the container to be filled with soybean milk, or impact is given to a sealed container having tofu packed therein.

Method for producing packed tofu

A method for producing tofu is described which includes the step of detecting the concentration of a coagulant in soybean milk. The coagulant concentration is detected by a coagulant concentration detector disposed downstream of a stirring apparatus in a soybean milk transfer circuit. The amount of addition of the coagulant is controlled by a coagulant concentration adjuster in accordance with the coagulant concentration detected by the coagulant concentration detector. This enables the mass production of tofu having a bouncy taste and excellent flavor.

Method and apparatus for producing tofu

The soybean milk containing a coagulant is primarily heated, packed into a molding container, and secondarily heated to complete coagulation. And, (1) the coagulated product (silken tofu) is transferred into a container for distribution, alternatively, (2) the coagulated product (silken tofu) is collapsed, and transferred into a draining container made of porous boards and pressed from the upper side to drain part of the water content, and the resulting momen tofu is transferred from the draining container into a container for distribution. Then, water is added to the container for distribution so as to allow the silken tofu or the momen tofu to sink under the water, followed by sealing.

Apparatus for producing tofu

A process for producing tofu comprising primarily heating soybean milk containing a coagulant, packing the soybean milk into a container, and secondarily heating the soybean milk to coagulate.

A process for producing packed tofu includes the steps of mixing soybean milk that has been heat-sterilized and cooled with (A) 0.01 to 0.3% by weight by volume of at least one coagulant selected from the group consisting of natural bittern, magnesium chloride, magnesium sulfate, calcium chloride, calcium primary phosphate, calcium sulfate, and calcium lactate and (B) 0.1 to 5 units, per gram of soybean milk protein, of transglutaminase either simultaneously or in the order (A) then (B), then packing and sealing the mixture in a container, then coagulating the mixture in the sealed container at a temperature of 70.degree. C. or lower by the action of the coagulant and transglutaminase, and thereafter heating the coagulated mixture to 75.degree. C. or higher in the sealed container to deactivate the transglutaminase and to complete the coagulation by the coagulant.
