Jungbunzlauer offers new Special Salts!

Basel, May 11, 2005 – The production of trisodium citrate anhydrous and magnesium citrates has started-up in Pernhofen, Jungbunzlauer's manufacturing site in Austria.

Magnesium Citrates

In addition to the existing range of organic calcium sources Jungbunzlauer has started to manufacture magnesium citrates for the use as mineral source in food supplements, foods for particular nutritional purposes, and pharmaceutical preparations.

Magnesium citrates are organic mineral sources and are preferred in many applications to inorganic sources because of their superior bioavailability and physiological compatibility.

Jungbunzlauer now offers the neutral magnesium citrates trimagnesium dicitrate anhydrous, trimagnesium dicitrate nonahydrate and the acid salts of citric acid, monomagnesium citrate (magnesium hydrogen citrate).

Jungbunzlauer magnesium citrates are available as USP and DAC qualities. Magnesium salts of citric acid are listed in Directive 2002/46/EC of the European Parliament and the Council relating to food supplements as vitamins and mineral substances which may be used in the manufacture of food supplements. Further, magnesium salts of citric acid are listed in Directive 2001/15/EC of the Commission on substances that may be added for specific nutritional purposes in foods for particular nutritional uses.

Trisodium Citrate Anhydrous

In addition to the already available regular trisodium citrate dihydrate Jungbunzlauer now offers the anhydrous counterpart.

The common hydrate form, trisodium citrate dihydrate, is widely used in foods, beverages and various technical applications mainly as buffering, sequestering or emulsifying agent, whereas the anhydrous form finds its uses in particular applications such as water sensitive dry blends and instant beverages, surfactants, fragrances as well as in tablets and OTC products.

Jungbunzlauer trisodium citrate anhydrous is manufactured from trisodium citrate dihydrate. Water molecules of the dihydrate crystals are removed by a patented process without destroying the original crystal matrix. The resulting crystals have a porous matrix that can be used as a carrier for inorganic and/or organic substances, especially after being impregnated with liquids. Furthermore, due to the absence of water, the product is not prone to caking. Trisodium citrate anhydrous is also used in applications where excess water is not desired.

Jungbunzlauer offers a technical grade and a food/pharmaceutical grade that meets United States Pharmacopoeia (USP), the Food Chemicals Codex (FCC) and European Commission Directive 96/77/EC purity criteria.
