Abstract This study's objective was to evaluate the effect of storage time (-18 ± 1 °C/60 days) under colorimetric, physicochemical, and lipid oxidation parameters in sheep meat sausages with oil pre-emulsified linseed to replace animal fat. Five formulations have been developed; the control sausage (0%) and four fat replacement levels with pre-emulsified linseed oil: 10, 20, 30, and 40%. Color analysis s (L *, a * and b *), determination of the total colorimetric difference (CD), water activity (Aw), pH, moisture, water retention capacity (WRC), and lipid oxidation through the number of substances reactive to thiobarbituric acid (TBARS), where all analysis were determined at intervals of 0, 20, 40 and 60 days of storage. The treatment, the storage time, and the interaction between these factors significantly affected (P < .0001) most of the studied parameters. The TBARS values were affected by the treatment (P < .0001) and by the storage days (P < .0001), with an interaction between these factors (P < .0001). However, it is suggested that the replacement of animal fat with pre-emulsified linseed oil was a viable strategy without causing detrimental effects on the product's quality during the storage period.
