Tóm tắt

Health concerns related to sodium intake have instigated work towards using salt replacers in salted foods such as smoked salmon. However, innovations in food may influence sensory perception and consumer acceptance for a product. This study investigates salt replacement and brine injection salting in smoked salmon from descriptive and hedonic sensory perspectives. Smoked salmon samples were produced by combining traditional or novel salting techniques (dry salting or brine injection) with traditional or novel salt types (NaCl or NaCl + KCl in a 2:1 ratio). The samples were evaluated with regard to their appearance, odour, taste, flavour and texture by a trained panel in a quantitative descriptive analysis. They were also evaluated by 102 Norwegian consumers in blind (taste only), expectations (product information only) and full information (taste and information combined) conditions. In addition to hedonic liking, the participants evaluated their willingness to pay for the products in a non-hypothetical, incentive-compatible procedure. Descriptive results show that brine injection samples differed in appearance, taste and texture from dry-salting samples, while NaCl + KCl samples obtained the same sensory profile as NaCl samples. Consumers prefer dry-salting samples, but do not discriminate between salt types, neither in liking nor in willingness to pay. Consumers most attracted by the fully traditional treatment are characterised by a frequent consumption of smoked salmon and a focus on nutrition and healthiness in food. Consumers most attracted by the fully innovative treatment tend to be convenience oriented and price conscious. The results indicate a market potential for partially salt-replaced smoked salmon.
