A metastable complex of calcium, citrate and malate is disclosed. This material is highly bioavailable, and is soluble in both neutral and acid solutions. The salt is prepared by the reaction of calcium carbonate, calcium hydroxide or calcium oxide with citric and malic acids in aqueous solution.
The preservative calcium sorbate is to be banned in the European Union due to a lack of safety data, the Commission has said. Calcium sorbate, also known as calcium salt, is a fine white crystalline powder used as a preservative as it prevents the growth of microbes, moulds and fungi in food. All ...

Potassium sorbate is often used to treat wines, because sorbic acid has lower water- solubility. The solubility of sorbic acid in water is 0.15%, by weight at 20 °C as compared to K-sorbate at 58.2% (20 °C). This salt is a white, crystalline powder and should be stored below 38 °C and should not be exposed to moisture, heat, or light.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum .
Sorbic acid does not create carcinogenic byproducts, as some preservatives such as nitrates do. It also has no noticeable taste or odor when used in baked goods. Its salts – sodium sorbate, calcium sorbate, and potassium sorbate – are more soluble in water than the original form.
POTASSIUM SORBATE. Potassium sorbate, white to slightly yellow crystalline powder, is the potassium salt of sorbic acid and is much more soluble in water than the acid. Potassium sorbate will releases back sorbic acid if dissolved in water. It is effective up to pH 6.5 but effectiveness increases as the pH decreases.
Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH 3 CH=CH−CH=CH−CO 2 K. It is a white salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative ( E number 202). Potassium sorbate is effective in a variety of applications including food, wine, and personal-care products.

Summary of TAP Reviewer's Analyses. 1 Potassium sorbate is petitioned for use in organic livestock production as mold inhibitor. Sorbic acid was first discovered in the Mountain Ash Tree (Sorbus aucuparia or Sorbus americana). Today most potassium sorbate is made synthetically. Potassium sorbate is a naturally occurring unsaturated fatty acid
Molecular Formula. A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers. PubChem uses the Hill system whereby the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms second,...
In the United States, BATF permits the use of sorbic acid and potassium sorbate to preserve wine. The maximum concentration of sorbic acid allowed in finished wine is 300 mg/L, (300 ppm). Sorbic acid (2,4-hexadienoic acid) is a straight chain unsaturated fatty acid with a molecular weight of 112.13 and the formula: CH3 - CH = CH - CH = CH - COOH.
Potassium sorbate contains 73.97% sorbic acid. In order to calculate the amount of potassium sorbate, the following formula should be used. Formula: ppm = mg/liter mg/liter of sorbic acid x 1.35 = mg/ liter of potassium sorbate Example: To obtain 200 ppm sorbic acid in wine, the following steps may be used.
sorbates are absorbed by a diffusion process in the stomach. Potassium and calcium sorbate might dissociate into their constituents—potassium, calcium and sorbate ions—in the small intestine. Accordingly, sorbate from potassium or calcium sorbate should be bioavailable and absorbed in the same manner as from sorbic acid.

The product is calcium hydrogen carbonate. Solubility of calcium and calcium compounds Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide.
Potassium sorbate is the potassium salt of sorbic acid, and is much more soluble in water than the acid. Potassium sorbate will produce sorbic acid once it is dissolved in water and is the most widely used food preservative in the world. It is effective up to pH 6.5 but effectiveness increases as the pH decreases.
The most commonly used products are sorbic acid itself (E200) and potassium sorbate (E202). In many countries sodium sorbate (E201) and calcium sorbate (E203) are also permitted. Sorbic acid is sparingly soluble in water, sodium sorbate has better solubility, and potassium sorbate is very freely soluble and can be used to produce 50% stock ...
Calcium sorbate used as a chemical preservative in food for human consumption is generally recognized as safe when used in accordance with good manufacturing practice. 21 CFR 182.3225 (4/1/99) from HSDB

Potassium sorbate E202 is the potassium salt of sorbic acid, chemical formula CH3CH=CH−CH=CH−CO2K, a white crystalline powder or granular or pellets. Potassium sorbate is a FDA approved preservative used in food to extend the shelf life of food, it is also effective in other uses such as in wine and personal care products.
Calcium sorbate is the calcium salt of sorbic acid. Calcium sorbate is a polyunsaturated fatty acid salt. Calcium sorbate is a polyunsaturated fatty acid salt. It is a commonly used food preservative ; its E number is E203, but it is no longer allowed to be used in the European Union.
