Measuring PH and Water Activity in Cured Reduced Oxygen Packaged Snack Sticks

  • Pin It

Abstract

A comparison of in-house and third party pH and water activity (aw) testing of cured, reduced oxygen packaged meat products was conducted. It took approximately 34 minutes 35 seconds to measure pH and aw for one sample and 14 minutes 10 seconds for subsequent samples. Results were not different (P ≥ 0.05) for pH and aw among laboratories or meters. The breakeven of in-house and third party testing for pH and aw is about 28 samples. Results will help small meat processors decide to purchase equipment and supplies for testing pH and aw or send samples out to a third party laboratory.
