Abstract

In this study, Canadian consumers’ preferences for enhanced carnosine (a naturally occurring dipeptide that exhibits antiaging properties) in pork are examined. Carnosine is a relatively unknown nutrient to the public such that we are interested in understanding the relative merits of informing consumers of enhanced carnosine levels through a possible health claim, a nutrient content claim or including it in the nutrition facts table (NFT). As a basis of comparison, we include two other possible labels, a protein nutrient content claim, and a Verified Canadian Pork label (created by industry identifying food safety, animal care, traceability, and farm to table quality assurance attributes of the production system). Data were collected through an online survey that included a choice experiment and were analyzed using conditional logit and random parameters logit models. Compared to carnosine (as a functional attribute), consumers prefer the identification of protein content. In terms of labeling carnosine, consumers have higher willingness to pay for carnosine content included in a NFT than for nutrient or health claims. Higher levels of nutrition knowledge are associated with higher willingness to pay for the different pork attributes. Dans cette étude, les préférences des consommateurs canadiens pour un niveau plus élevé de carnosine (un dipeptide naturel qui présente des propriétés anti‐vieillissement) dans le porc sont examinées. La carnosine est un élément nutritif relativement inconnu du public, de sorte que nous souhaitons comprendre le bien‐fondé d'informer les consommateurs sur des niveaux de carnosine plus élevé au moyen d'une allégation relative à la santé, d'une allégation sur la teneur en éléments nutritifs ou à son inclusion dans le tableau de la valeur nutritive (TVN). À titre de comparaison, nous incluons deux autres appellations possibles, une allégation nutritive de teneur en protéines et une appellation Porc Canadien Vérifié (créée par l'industrie identifiant les attributs du système de production relatifs à la sécurité alimentaire, aux soins des animaux, à la traçabilité et à l'assurance de la qualité de la ferme à la table). Les données ont été recueillies au moyen d'une enquête en ligne comprenant une expérience de choix et analysées à l'aide de modèles logit conditionnels et de paramètres aléatoires. Par rapport à la carnosine (en tant qu'attribut fonctionnel), les consommateurs préfèrent l'identification du contenu en protéines. En ce qui concerne l’étiquetage de la carnosine, les consommateurs sont plus disposés à payer pour la teneur en carnosine incluse dans un TVN que pour les allégations relatives aux éléments nutritifs ou à la santé. Des niveaux plus élevés de connaissances nutritionnelles sont associés à une plus grande volonté de payer pour les différents attributs de la viande de porc.
