Product Description

 

Product Description

 

Uses of calcium sulfate in food include: nutrient, yeast activator, dough modifier, curing agent, chelating agent, gelling agent, baking powder, carrier, filler, pH regulator, and abrasive. Among these uses it is mainly used in baked goods. It is used as a curing agent in canned potatoes, tomatoes, carrots, string beans, and peppers. Calcium sulfate is also used as an ingredient in confectionery, ice cream, and other frozen desserts. Calcium sulfate is also used in beer brewing and is added to the malting process to increase the amount of calcium ions in the water. Calcium sulfate is used as an abrasive in cleaning agents used in contact with foods. Calcium sulfate is also used in cosmetics and toothpaste.

1. Phosphogypsum is a moist, fine powder with a free water content of ca. 20 - 30 % and considerable amounts of impurities, the exact impurities and their amounts depending on the rock and the specific process. The radioactive substances present in small amounts in sedimentary phosphate rock are partly transferred to the phosphogypsum as 226Ra, leading to slightly increased radioactivity of such gypsums. 
2. Calcium sulphate (CaSO₄) is a white solid that occurs naturally as a mineral anhydrite. It is found more commonly as dihydrate, called gypsum (CaSO₄·2H₂O). When heated, gypsum loses water at 128°C to give a hemihydrate (2CaSO₄·H₂O), also known as plaster of Paris.
Calcium sulphate is sparingly soluble in water and makes water permanently hard. CaSO₄ is used in the manufacture of certain paints, ceramics and paper.
Gypsum is the cheapest and the most useful material in reclamation of sodic soils.Calcium, solubilized from gypsum, replaces sodium, leaving behind the watersoluble sodium sulphate, which is leached out as a result of the following reactions in the soil:
Since both reactions are reversible, adequate leaching arrangements have to be made to remove sodium sulphate.
The application of about 40 t/ha of gypsum in Nevada (USA) was seen to increase water infiltration and the depth of water penetration substantially. These two measures increased hay yield up to 2.3 t/ha per year.
Gypsum requirement (GR) is the amount of gypsum necessary to be added to reclaim soil and is calculated using the formula:
The gypsum requirement is equivalent to (Na_x)×4.50 metric tons of gypsum per hectare for a 30 cm fixed depth, where Na, is the milliequivalent of exchangeable sodium to be replaced by calcium from the added gypsum.
