VALIDATION OF MOHR’S TITRATION METHOD TO DETERMINE SALT IN OLIVE AND OLIVE BRINE

Abstract

The aim of this study was to test Mohr method’s performance characteristics and to checkacceptability of test results during the routine salt analysis in the production phase of Çakıstes table olives.The method was validated using three fortified samples, i.e. salt solutions in water, cracked olive’s brine andolive at three different levels of 3, 5 and 7% salt concentration at three different times. Overall recovery of themethod was 107% for all three commodities over the validation range with a relative standard deviation of 5%(n=162). The regression coefficient (R2) was found to be 0.998 in olive matrix. Typical limit of detection was0.1% with the method.
