The main goal of this research was to determine the effectiveness of saturated fat replacement by means of a canola oil oleogel, termed an “organogel”, using ethyl cellulose (EC, 10 cP) as the gelator and sorbitan monostearate (SMS) as a plasticizer. All-beef frankfurters and pork breakfast sausages were used and instrumental tests performed to determine effectiveness were light microscopy, texture profile analysis, Warner-Bratzler shear force, cook loss and smokehouse yield. A trained sensory analysis panel scored for hardness, juiciness, oiliness, and the presence of off flavours. Replacing beef fat (BF) with canola oil (CO) in frankfurters produced a product that was significantly harder (P < 0.05). The gelling of the canola oil lowered the TPA hardness values. Cohesiveness, chewiness and gumminess values were statistically similar to the BF control. Minor changes in L*, a* and b* values were observed, with the organogel frankfurters being lighter than the BF control. Sensory analysis scores showed that 8,10 & 12% EC frankfurters were significantly less hard than the CO control. / Ontario Ministry of Agriculture, Food & Rural Affairs (OMAFRA)
