Abstract

En 2002, un programme national d'amélioration de la qualité des produits agricoles a été lancé dans le cadre du projet « renforcement des services d’appui à l’agriculture » en collaboration avec la Banque Mondiale. Ce programme vise la promotion de la qualité des viandes depuis le producteur jusqu’au consommateur. Par conséquent, l’impact des variables démographiques et économiques des consommateurs sur leurs préférences pour la viande n’a pas été suffisamment étudié dans la littérature nationale ainsi que le suivi de l'évaluation de ce programme. Afin de combler cette lacune, ce travail a pour objectif d’analyser le niveau et les déterminants de la perception de la qualité des viandes en Tunisie. En utilisant la classification d’Ettabti (2005) qui regroupe les attributs de la qualité des viandes en trois catégories (qualité attendue, qualité d’expérience et qualité de croyance), nous avons déterminé deux indices : Moyenne des Scores des Attributs (MSA) et Indice de Qualité des Viandes (IQV). Un échantillon de 504 ménages répartis de façon égale entre les sept régions du pays (Grand Tunis, Nord Est, Nord Ouest, Centre Est, Centre Ouest, Sud Est et Sud Ouest) a été sélectionné. Une régression logistique ordonnée a été réalisée et a permis d’identifier les déterminants sociodémographiques et économiques de la qualité des viandes. Les résultats basés sur les MSA indiquent que les principaux attributs de qualité sont la couleur et la mention produit contrôlé pour la qualité attendue, le goût après cuisson et l’odeur après cuisson pour la qualité d’expérience et riche en cholestérol et riche en protéines pour la qualité de croyance. Les résultats de la régression logistique montrent que le niveau d’éducation et le revenu expliquent positivement l’indice de qualité des viandes alors que le gendre et l’âge l’expliquent négativement. Ces résultats impliquent que le développement de la distribution moderne en général et des filières des viandes rouges en particulier contribuera sans doute à modifier la perception de la qualité des viandes en Tunisie. Mots clés : Indices de qualité, facteurs socioéconomiques, viandes, Tunisie....... In 2002, a national programme on the promotion of agricultural quality products was launched within the called « strengthening of agriculture support services project » in collaboration with the World Bank. The main objective of this program has been the promotion of meat quality from the producer to the consumer. Consequently, of the consumer demographic and economic variables impacts on their preferences for meat have been insufficiently studied at national literature and follow up on the assessment of such program. In order to fill this gap, the objective of this study is to analyze the determinants of meat quality perception in Tunisia. Using Ettabti (2005) classification for meat quality attributes (expected quality, know-how quality and quality of belief), two indices have been constructed: Mean Attribute Scores (MSA) and Meat Quality Index (IQV). A random sample of 504 consumers distributed equally between the seven country areas (Tunis City, North East, North West, Central East, Mid West, South East and South West) has been selected. Ordered Logistic Regression technique has been used to identify the socio-demographic and economic determinants of meat quality. Empirical findings based on the MAS scores indicates that the main attributes of quality are colour, controlled product and the price for expected quality, taste, smell and time of cooking for know-how quality; and cholesterol and protein content for quality of belief. The estimated ordered logistic regression model reveals that level of education and the household income explain positively the meat quality index. Whereas, gender and age affects negatively the perception of meat quality. Finally, these findings suggest that the development of supermarket in general and meat sector in particular will, certainly, contribute to modify consumer behaviour towards meat quality attributes in Tunisia.
