Antioxidant properties of liquid smoke in precooked beef patties

Abstract

Liquid smoke (LS) effectiveness in controlling lipid oxidation and warmed-over flavor (WOF) in beef was investigated. Aroma scores, "α-thiobarbituri c acid (TBA) numbers, and pH values were lower (P<.05) in LS-treated beef patties than in patties without LS. LS has useful antioxidative properties in precooked ground beef patties at the normally recommended percentage of 1.5%. That should reduce undesirable flavor development and product loss.
