Effects of replacing pork back fat with cellulose fiber in Pariser sausages

In order to evaluate the effect of cellulose fibers addition as pork back fat substitute on the quality of Pariser sausages, five groups were produced: control (C) containing 20% back fat and products where 1/4 (EG I), 1/2 (EG II), 3/4 (EG III) and total (EG IV) of back fat was replaced. The moisture content increased from 59.85% (C) to 75.12% (EG IV) and the fat content decreased from 22.41% (C) to 6.68% (EG IV). The PUFA/SFA ratio increased desirably from 0.52 (C) up to 0.64 (EG IV), while Omega 6/Omega 3 ratio was less favourable (20.10 by C to 34.26 by EG IV). Color (L*, a*, b*) was unchanged, but hardness and chewiness decreased while cohesivness increased by EG IV compared to the other groups. Sensory evaluation showed no signifficant difference between control (4.60) and modified sausages up to 3 / 4 backfat replacement (4.57 - 4.50), while EG IV were the least evaluated (4.37).
