Dipotassium Phosphate
Dipotassium phosphate (also dipotassium hydrogen orthophosphate or potassium phosphate dibasic) is the inorganic compound with the formula K2HPO4.(H2O)x (x = 0, 3, 6). Together with monopotassium phosphate (KH2PO4.(H2O)x), it is often used as a fertilizer, food additive, and buffering agent. It is a white or colorless solid that is soluble in water. It is produced commercially by partial neutralization of phosphoric acid with two equivalents of potassium chloride: : H3PO4 + 2 KCl → K2HPO4 + 2 HCl Uses As a food additive, dipotassium phosphate is used in imitation dairy creamers, dry powder beverages, mineral supplements, and starter cultures. It functions as an emulsifier, stabilizer and texturizer; it is also a buffering agent, and chelating agent especially for the calcium in milk products. As a food additive, dipotassium phosphate is generally recognized as safe by the United States Food and Drug Administration, and is commonly used (in conjunction with other inorganic sal ...

Deliquescent
Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption (chemistry), absorption or adsorption from the surrounding Natural environment, environment, which is usually at normal or room temperature. If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g. changing in volume, boiling point, viscosity or some other physical characteristic or property of the substance. For example, a finely dispersed hygroscopic powder, such as a salt, may become clumpy over time due to collection of moisture from the surrounding environment. ''Deliquescent'' materials are sufficiently hygroscopic that they dissolve in the water they absorb, forming an aqueous solution. Hygroscopy is essential for many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal. Biological evolution created hygroscopic solutions for water harvesting, filament tensile strength, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Chloride
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. KCl is used as a salt substitute for table salt (NaCl), a fertilizer, as a medication, in scientific applications, in domestic water softeners (as a substitute for sodium chloride salt), as a feedstock, and in food processing, where it may be known as E number additive E508. It occurs naturally as the mineral sylvite, which is named after salt's historical designations ''sal degistivum Sylvii'' and ''sal febrifugum Sylvii'', and in combination with sodium chloride as sylvinite. Uses Fertilizer The majority of the potassium chloride produced is used for making fertilizer, called potash, since the growth of many plants is limited by potassium availabil ...

Food Additives
Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities. Some additives, such as vinegar ( pickling), salt ( salting), smoke (smoking) and sugar (crystallization), have been used for centuries to preserve food. This allows for longer-lasting foods, such as bacon, sweets, and wines. With the advent of ultra-processed foods in the late 20th century, many additives having both natural and artificial origin were introduced. Food additives also include substances that may be introduced to food indirectly (called "indirect additives") in the manufacturing process through packaging, storage or transport. In Europe and internationally, many additives are designated with E numbers, while in the United States, additives in amounts deemed safe for human consumption are designated as GRAS. Identification To regulate these additives and inform consumers each additive is assigned a unique number called an "E number", which ...

Acid Salts
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word ''acid'' is derived from the Latin , meaning 'sour'. An aqueous solution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphates
Phosphates are the naturally occurring form of the element phosphorus. In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, phosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one proton gives the dihydrogen phosphate ion while removal of two protons gives the hydrogen phosphate ion . These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

Potassium Compounds
Potassium is a chemical element; it has symbol K (from Neo-Latin ) and atomic number19. It is a silvery white metal that is soft enough to easily cut with a knife. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge (which combines with anions to form salts). In nature, potassium occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in seawater (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, a common constituent of granites and oth ...

Generally Recognized As Safe
Generally recognized as safe (GRAS) is a United States Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts under the conditions of its intended use. An ingredient with a GRAS designation is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. The concept of food additives being "generally recognized as safe" was first described in the Food Additives Amendment of 1958, and all additives introduced after this time had to be evaluated by new standards. Some examples of substances recognized as GRAS include ascorbic acid (vitamin C), citric acid, and salt, which are all commonly used in food preservation and flavoring. The FDA list of GRAS notices is updated approximately each month, as of 2021. History On 6 September 1958, the Food Additives Amendment of 1958 was signed into law, with a list of 700 food substances that were exempt from the then-new requirement ...

Non-dairy Creamer
A non-dairy creamer, commonly also called tea whitener or coffee whitener or else just creamer, is a liquid or granular product intended to substitute for milk or cream as an additive to coffee, tea, hot chocolate, or other beverages. Most do not contain lactose and therefore are commonly described as being dairy-free, non-dairy products, although many contain casein, a milk-derived protein. Dry granular products do not need to be refrigerated and can be used and stored in locations which do not have a refrigerator. Liquid non-dairy creamers should be tightly capped and refrigerated after opening. Some non-dairy creamers contain sweeteners and flavors, such as vanilla, hazelnut, or Irish cream. As with other processed food products, low calorie, low-calorie and low fat, low-fat versions are available for non-dairy creamers.
