Vitiva launches concentrated rosmarinic acid

Slovenian rosemary extracts producer Vitiva has developed a highly concentrated form of the water-soluble antioxidant rosmarinic acid targeting dietary supplements, cosmeceuticals and food products.

"Rosmarinic acid is a well-known antioxidant, however, up till now only relatively low concentration products were commercially available to the market. This had limited its use to a very narrow number of applications," said chief executive Ohad Cohen.

He says the firm can now produce a range of concentrations from 5 per cent to 70 per cent.

"For example, AquaROX can be used in capsules, thus saving space or reducing the size of tablets," added Cohen.

Rosmarinic acid is found in large quantities in herbs like oregano, lemon balm, sage, marjoram and rosemary. Its antioxidant activity is said to be stronger than that of vitamin E. This means that it helps to prevent cell damage caused by free radicals, which is thought to cause chronic diseases like cancer and heart disease.

The ingredient has therefore been marketed in capsules for consumers looking for additional disease protection.

Rosmarinic acid also has anti-inflammatory properties. A study published last year found that the oral administration of rosmarinic acid is an effective intervention for allergic asthma. Another study demonstrated that it suppressed synovitis in mice and that it may be beneficial for the treatment of rheumatoid arthritis.

It can also be used in all water-based applications like energy drinks, bars and breakfast cereals. When added to food to improve its shelflife, the high concentration means that there are fewer ingredients that can effect the product's organoleptic characteristics, claims Vitiva.

Rosemarinic acid also has specific antimicrobial and antimicotic properties that are valuable in cosmeceutical formulations, according to the firm.
