Burgers (20% pork back fat) were produced with the replacement of 0, 20, 40, 60, 80, and 100% of pork back fat by hydrogelled emulsion (HE) from chia and linseed oils. No changes (P > .05) were observed for the moisture retention, diameter reduction, and cooking loss of the treatments, with a significant increase in the lipid retention (P < .05). Hardness increased (P < .05) with increasing the lipid replacement level, and a significant color difference (ΔE) was detected between the treatments and the control. In addition to reducing animal fat, a healthier fatty acid profile was reached after the lipid reformulation of the burgers, thus allowing the burgers to be labeled with health claims. The sensory tests (acceptance and Check-All-That-Apply) indicated that it is possible to replace up to 60% of pork back fat by HE.
