In accordance with the present invention, there is provided a method for producing colored tofu, the method comprising a step of preparing a liquid dispersion constituted by a colorant and a paste or powder of vegetables or fruit uniformly dispersed in sugar alcohol or a dilute aqueous solution thereof; a step of preparing a liquid soy milk mixture by uniformly mixing the liquid dispersion, soy milk, and a coagulating agent; and a step of coagulating the liquid soy milk mixture to produce tofu.

Tofu is typically sold saturated in liquid, and in order for the tofu to take on a desired flavour, the liquid content of the tofu must first be reduced. The present invention provides a method of reducing the liquid content of tofu and a tofu press 10, comprising: a tray 20 for receiving tofu 30 therein; a pressure member 80 for applying pressure to the tofu 30 within the tray 20; and a toggle latch 120 releasably coupleable between the tray 20 and the pressure member 80 such that pressure is applied to the tofu 30 within the tray by the pressure member 80.

A tofu press includes: an open container, a foldable plate, a pressing plate, a spring assembly, and an end cover, where the foldable plate is configured to be placed at a bottom of the open container, the foldable plate includes a bottom plate and lateral plates disposed at two sides of the bottom plate, the lateral plates are perpendicular to and connected to the bottom plate, the pressing plate is configured to cover and press a top of the bottom plate, a bottom end of the spring assembly is configured to press the pressing plate, and the spring assembly is fixedly connected to the end cover; and the pressing plate, the lateral plates, the bottom plate, and two faces of the open container form a compression operating area. The tofu press ensures uniform pressing at the time of pressing a food material to dehydrate.

Microorganisms and bioprocesses are provided that convert gaseous substrates, such as renewable H.sub.2 and waste CO.sub.2 producer gas, or syngas into high-protein biomass that may be used directly for human nutrition, or as a nutrient for plants, fungi, or other microorganisms, or as a source of soil carbon, nitrogen, and other mineral nutrients. Renewable H.sub.2 used in the processes described herein may be generated by electrolysis using solar or wind power. Producer gas used in the processes described herein may be derived from sources that include gasification of waste feedstock and/or biomass residue, waste gas from industrial processes, or natural gas, biogas, or landfill gas.

Provided is a method for producing a vegetable fresh cheese-like food product which is free from dairy products, has a natural, fresh cheese-like dairy flavor and body, and has excellent spreadability and squeezability as a confectionery material. The pH of an emulsified oil composition which contains a soybean emulsified composition containing a specific protein and lipid, a specific soybean protein material having a reduced content of a lipophilic protein among soybean proteins, and a protein coagulant is adjusted to a pH of 5.5-6.3 using lactic acid fermentation and/or an organic acid.

Tofu products and methods of making the same. The tofu products may include one or more layers. A first layer may include added fat, and a second layer may include no added fat. The fat may be introduced into the soymilk prior to curdling. The first and second layers may be layered to form a layered tofu product such as a bacon analog.

The present invention provides intestinal flora-improving health food which improves intestinal flora by containing bittern derived from deep-ocean water to increase and activate Equol-producing bacteria. The intestinal flora-improving health food comprises 0.8 wt % to 1.5 wt % of bittern relative to the total weight of the health food, wherein the bittern per 100 g comprises 2500 mg to 6000 mg of magnesium content and 500 mg to 2000 mg of calcium content; wherein the proportion of magnesium content to calcium content in the bittern is 2 to 7, and wherein the hardness of the bittern is at 144000 mg/L to 383000 mg/L.

The present invention relates to a method for preparing tofu by using freeze coagulation and, more specifically, to a method for preparing tofu and tofu prepared by the preparation method, the method comprising the steps of: cooling soymilk to an appropriate temperature; adding an appropriate coagulant into the cooled soymilk; freezing the soymilk into which the coagulant has been added; and maintaining the temperature to be below the freezing point and heating the frozen material after a predetermined time. The tofu according to the present invention has excellent mouthfeel and flavor and can be prepared having a structure and physical properties differentiated from those of conventional tofu.
