Effect of Water Activity on Lipid Oxidation and Protein Solubility in Freeze-dried Beef during Storage

Ground beef patties (15% fat) were freeze-dried to different a(w) endpoints and stored at 25°C or 49°C. Water activity, total moisture (%), lipid oxidation (TBARS@450nm), and protein solubility were evaluated. TBARS @450nm was favored at 49°C, but not at 25°C except at high a(w) range (p < 0.05),...
