Tecna has released a couple of enzyme-linked immunosorbent assay (ELISA) kits to detect zearalenone in cereals and feed.

Celer ZEA and B ZERO ZEA will replace the Celer ZON v3 and B ZERO ZON kits.

Both kits have an assay time of 20 minutes.

Tecna said the kits are validated for the screening of maize, wheat and swine feed to set the Limit of Quantification (LOQ) at 10, 25 and 50 ppb.

The average trueness when analyzing 50 and 100 ppb spiked samples, in terms of recovery, is 80±7% on maize, 90±9% on wheat and 103±20% on complete and complementary feedstuffs, the firm added.

It said Zearalenone detection in cereals and cereals by-products was fundamental to assess food and feed safety.

Extraction of zearalenone from the sample is done by a 70% methanolic solution and sodium chloride (NaCl).

The B ZERO ZEA kit is for those who have to analyze few samples per analytical session.

This format does not require the implementation of a calibration curve at every analysis, saving time and reagents, added Tecna.
