US issues new patent to Kemin for screening antioxidants
 

Press release
 

The United States Patent Office recently issued a new patent to Kemin Industries, Inc., which protects a Kemin proprietary method for the high-throughput screening of antioxidants at near ambient temperatures.

The newly patented method was developed to improve prediction accuracy of antioxidant performance under accelerated storage conditions. These accelerated tests are required to by-pass lengthy shelf life studies for the screening and selection of antioxidants.

"Because the oxidation assays can now be performed at near ambient temperatures, it is possible to analyse the oxidative stability of a wide variety of heat-sensitive products much more efficiently than in conventional accelerated assays at high temperatures," said Stefaan Van Dyck, senior research scientist at Kemin and one of the inventors of this method.

Van Dyck concluded that the method could be a valuable tool to identify the most suitable antioxidant formulation and dosage to efficiently protect a specific feed or food product against oxidative damage.

Other recent Kemin patents in the antioxidant field include:

• Method for removing essential oils and antioxidants from extract products of lamiaceae species using rolled film evaporation (2002)
   
• Method of extracting antioxidants from lamiaceae species and the extract products thereof (2004)
   
• Method for simultaneous extraction of essential oils and antioxidants from labiatae species and the extract products thereof (2005)
