silken tofu can be blended into sauces or used as desserts or drinks. Other types of tofu include fermented tofu, flavored tofu, fried tofu, and frozen tofu. Nutritionally, tofu is cholesterol free, low in saturated fat, and high in protein. On a moisture-free basis, tofu contains about 50% protein and 27% fat, most of

Air fryer tofu. Place the tofu pieces in a single layer in the air fryer basket (work in batches so the pieces aren't crowded). Air fry at 400ºF for 10 to 15 minutes or until the pieces are golden and crispy, shaking the basket after 10 minutes. Plate the tofu and drizzle the reserved marinade over top. Enjoy!

The 7S conglycinin and 11S glycinin are the key components of tofu curd, accounting for more than 70% of the total soy protein content []. 7S conglycinin is a trimer composed of an α subunit, α′ subunit, and β subunit and accounts for approximately 30% of the soy protein content []. 11S glycinin is a hexamer composed of acidic polypeptides (A) …

The aqueous mineral carbonation reaction was carried out inside a 2-L high-pressure stirred tank. This tank was connected to a CO 2 gas inlet line which provided CO 2 gas (99.9%) from a gas ...

INTRODUCTION. Tofu or soybean curd is a gel-like food made by adding coagulants to soybean milk. The four basic types of coagulants that are used to make tofu are: (1) "nigari-type" or chloride-type coagulants such as magnesium chloride (MgCl 2) and calcium chloride (CaCl 2); (2) sulfate-type coagulants such as calcium sulfate (CaSO 4) …

Gypsum is considered both a sedimentary rock and a mineral. Its chemical formula is CaSO 4 ∙2H 2 O. Because gypsum formed when ancient seas evaporated in Oklahoma during Permian time (299-251 million years ago), geologists classify it as an evaporite.Western Oklahoma has many large deposits of gypsum totaling trillions of tons …

I like to use gypsum when making homemade soft or silken tofu. In a pinch, you can also use 2 tablespoons lemon juice mixed …

Gypsum occurs in two main varieties as white earthy masses or as clear crystals. In crystal form, its softness and single perfect cleavage with two less well-developed cleavage directions usually serve to distinguish gypsum from other similar-looking minerals. Anhydrite: When gypsum loses its water component, it forms the mineral anhydrite …

Mineral salt coagulants work by uniting bivalent cations with deprotonated phosphate groups, which is a mechanism that is effective for soy milk production (Kanauchi, Hatanaka, & Shimoyamada, 2015). Nigari (NGR) and gypsum (GYP) are the most popular traditional coagulants that have been used as mineral salts in tofu production.

Gypsum (calcium sulfate) Characteristics: Yields mild-tasting tofu that is slightly more tender than nigari tofu. Adds a significant amount of calcium to tofu. Availability: Use food-grade gypsum, which is also …

Gypsum is a soft mineral composed of calcium sulphate dihydrate ( CaSO4 ⋅ 2H2O C a S O 4 ⋅ 2 H 2 O ). It is commonly found in sedimentary rock formations distributed all over the world. It is a white or greyish material and is water soluble. Hence it can easily be used to produce plaster and drywall where it is mixed in water to form a paste.

Most importently, the purified gypsum showed high CO 2 sequestration efficiency for CO 2 mineral sequestration and through which high value added CaCO 3 product can be obtained. View full-text Article

The deterioration of buildings and monuments by gypsum is the result of crystallization cycles of this salt. Although gypsum can dehydrate to a hemihydrate, the mineral bassanite, and to an anhydrate, the mineral anhydrite, this reaction occurs in nature on a geological time scale and therefore it is unlikely to occur when gypsum is …

Gypsum: A Versatile Mineral. Gypsum, scientifically known as Calcium Sulfate Dihydrate (CaSO 4 ·2H 2 O), is a naturally occurring mineral primarily formed from the evaporation of ancient bodies of sea water and lakes. It is a soft, transparent to translucent crystal that is typically white or colorless but can take on other hues when ...

Gypsum. Gypsum, also called calcium sulfate, is the most widely used coagulant in making tofu. You'll often find calcium sulfate in tofu incredibly inexpensive to make, as it's mined from geological deposits and requires no extra refining. See more

Purified gypsum mineral carbonation experiment. After removing impurities, the purified gypsum could be used to capture CO 2 and prepare a high-value-added CaCO 3 product. Enhancing carbonation with ammonia under increased CO 2 pressure was employed to shorten the reaction time. The process can be expressed as follows:

Step 1: Preparing the Soy Milk. Start by heating the soy milk in a large pot over medium heat until it reaches a temperature of around 180°F (82°C). This temperature is crucial as it helps to denature the proteins in the soy milk, which is essential for achieving the right texture of silken tofu. Keep a close eye on the temperature using a ...

This research was aimed to evaluate the effects of calcium coagulants (10–40 mmol/L in soymilk) including calcium chloride, calcium lactate, and calcium gluconate on the textural properties (microstructures, large deformation behaviors under uniaxial compression) and some relevant chemical properties of firm tofu. The results …

Prepare a heatproof bowl or container that can hold at least 2 cups of water and will fit into your steamer. Add the gypsum, salt/sugar if using, and a small amount of soy milk into the bowl. Mix until fully dissolved. Then slowly pour in the rest of the soy milk and stir constantly to mix in the gypsum.

Geology and Mineralogy. Gypsum (CaSO 4 •2H 2 O), calcium sulfate dihydrate, has the unique property of releasing 1.5 molecules of water when heated to about 320-350 o F. The resulting chemical compound, calcium sulfate hemihydrate (CaSO 4 •½H 2 O) will, in turn, react with water to reform gypsum. This property is the basis for gypsum's ...

1.2 Plasterboard. Plasterboard, also known as drywall or wallboard, forms an integral part of modern construction. It's made by compressing an inner layer of gypsum between two outer layers of heavy paper or fibreglass mat. Being lightweight and easy to install, it's commonly used to form interior walls and ceilings.

Using a tofu mold, cover the mold inside with wet cheesecloth, and scoop the curd into the mold. Fold the edges of the cheesecloth on top of the soybean jelly. Place a heavy object on top to press it down for 6 hours. Take the tofu out of the mold. You can steam, pan fry to add the tofu to your soup or stew. Enjoy!

Step 1: Make the Soy Milk. Before making tofu, you need to make soy milk. Since this part of the recipe calls for soaking overnight, start the day before making tofu. Place 3 cups of dried soybeans in a medium …

The moisture content of the produced tofu was between 78% and 85%, which is higher than the values reported by Shi et al. for tofu obtained with magnesium chloride (57.7%), calcium sulphate (63.3%), or GDL (76.3%), but similar to the values reported by Kim et al. for tofu obtained with calcium sulphate (83.4%) and by Lee et al. …

2.4 Preparation of tofu. Tofu was prepared according to the tofu manufacturing method of Lee et al. and Woo et al. with modifications to the amount of soybeans used. In 6000 g of water (10 times the weight of the soybeans used), 600 g of control soybeans (general-use soybeans) were soaked for 12 hr, and 530 g of SDSs …

Pressing Tofu. Line a tofu mold with a cheesecloth or muslin cloth and ladle the curds into the mold carefully, allowing excess liquid (whey) to drain away. Once all curds are transferred to the mold, fold over the lining cloth inward and put a lid on and about 400g of weight for about 15 minutes.
