Physical, chemical and sensory characteristics of cooked meat emulsion style products containing vegetable oils

Beef frankfurters and cooked salamis (containing 19.5% pork back fat) were compared with samples containing vegetable oils. The pork back fat was replaced with Soya-seed oil (19.5%), sunflower oil (19.5%, 24%, 27.5%), cotton-seed oil (19.5%), corn-seed oil (19.5%) or palmine (19.5%). The emulsion stability of the products containing vegetable oil was good, even if the temperature of the batters reached 20 degrees C. However, firmness, lightness of internal colour and flavour intensity were reduced in the vegetable oil specimens. In terms of flavour, panellists scored the acceptability of the experimental products as follows: control best; sunflower, corn-seed and palmine next and soya- and cotton-seed worst.
