ISO 17025 ACCREDITATION TO DETERMINE THE SENSORY QUALITY AND FOOD SAFETY IN DRY-CURED HAM AND DRYCURED SHOULDER. L. Lorido, L. Sánchez-Montero, M. Asensio, D. Caballero, N. Martín, C.

INTRODUCTION

The Innovation and Analysis in Animal Source Foodstuffs (SiPA) takes part of the Support research Services of the University of Extremadura (SAIUEx). The service offer has been adapted to the demands of the companies. The ISO 17025 standard is the single most important standard for calibration and testing laboratories around the world. Laboratories that are accredited to this international standard have demonstrated that they are technically competent and able to produce precise and accurate test and/or calibration data. MATERIALS AND METHODS

Nowadays there are three analysis techniques which are in accreditation process by ISO 17025 standard in dry-cured ham and dry-cured shoulder in the SiPA service: 1) sensory analysis with an exhaustive trained sensory panel (QDA: quantitative descriptive analysis). 2) determination of Salmonella spp and Listeria monocytogenes by PCR-RT (Polymerase Chain Reaction Real Time). 3) determination of numerous acaricides by GC-MS (Gas Chromatography -Mass Spectrometry). RESULTS • Figure 1 shows a spider chart with the average intensity of the different sensory attributes evaluated in Iberian drycured ham by the sensory panel in the process of accreditation. •Figure 2 shows a positive result of Piperonylbutoxide in a fat sample of Iberian dry-cured ham. •Figure 3 shows the Ct values of Listeria monocytogenes obtained by the PCR Real Time in Iberian dry-cured ham.

CONCLUSION

The obtaining of the accreditation for these three analysis techniques by the SIPA will results in an important development and a tool for companies to produce higher quality and safer dry-cured products.
