Dry fermented sausage (“Chorizo”) was reformulated to produce better lipid compositions (reduced fat
content and improved fatty acid profile) by replacing the pork backfat by a healthier oil combination
(olive, linseed and fish oils) stabilized in a konjac matrix. Proximate analysis, fatty acid profiles, lipid
oxidation and sensory analysis were studied. The fat content was 99e130 g/kg in the low-fat versus
316 g/kg in the normal fat sausages. The incorporation of an oil-in-konjac matrix reduced (P < 0.05)
saturated fatty acid content and increased (P < 0.05) polyunsaturated fatty acids (PUFA), improving the
ne6/ne3 ratio in dry sausage. Reducing fat decreased (P < 0.05) hardness and increased (P < 0.05)
cohesiveness, with no effect (P > 0.05) on springiness and chewiness. The reformulation process
produced a decrease (P < 0.05) in all sensorial parameters, compared with the control sample, although
in all the sausages appearance, flavour and juiciness scored above the middle value on the hedonic scale.
