Abstract

Sodium lactate and acetic acid derivatives were evaluated for their impact on fresh Italian pork sausage links using commercial pork trimmings. Treatments included: 2.5% acetic acid (48.5%) –sodium lactate mixture (51.5%) (V), 2.5% sodium lactate (60% solids) (S), control –0.02% BHA/BHT (B) and negative control –seasoning only (C). Analysis over storage included total plate count (TPC), oxidative rancidity (TBARS), sensory analysis (descriptive and consumer), cooking loss, pH, and color. The S and V treatments had lower TPC (P<0.05) from days 5 through 14 when compared to B and C. TBARS values increased (P<0.05) for treatments C, S, and V while B was did not change (P>0.05) over time. While CIE a* surface values for redness generally decreased over time for all treatments, treatment B maintained more redness over the storage period. Of consumers tested, 85.6% rated all treatments between like slightly and like very much.
