Kemin improves screening of antioxidants

01-08-2007 | |

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 the accuracy of the
prediction 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 analyze the oxidative stability of a
wide variety of heat-sensitive products much more efficiently than in
conventional accelerated assays at high temperature,” said Stefaan Van Dyck,
principal scientist at Kemin Europa and one of the inventors of this method.
 “The method therefore can 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)
