Abstract
The effects of the inoculation of a mixed starter culture and vacuum packaging (during resting stage) on odour, appearance, texture and flavour of dry-cured ham were studied. After salting, half of the 36 processed hams were inoculated with a commercial starter culture containing lactic-acid bacteria, Gram-positive catalase-positive cocci and yeasts. Nine hams per group (inoculated and non-inoculated) remained vacuum-packaged during resting. External odour during the process, as well as appearance of the cut surface, texture and flavour on semimembranosus and biceps femoris of the final product were assessed. Vacuum packaging during resting caused an increase in white film and feedstuff flavour, as well as a decrease in aged flavour, hardness, fibrousness and overall liking. The use of the starter culture brought about an increase in feedstuff flavour, a decrease in sweetness, aged flavour, nutty flavour and overall liking and, only in vacuum-packaged hams, the development of a floral flavour, but had no significant effect on texture descriptors. The starter culture studied is considered inappropriate for the production of traditional Spanish dry-cured ham regardless of the type of resting used.
