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°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.
