International audience ; Assessing consumers' acceptability of traditional pork products (TPP) from local pig breeds is essential to ensure sustainability of regional pork chains. As part of TREASURE project, expectations and hedonic perception of Protected Designation of Origin (PDO) Noir de Bigorre (NB) dry-cured ham produced from pure Gascon breed were assessed. The study was conducted in Toulouse (France) as expanding market for TPP with 124 consumers, regular purchasers of TPP (quota sampling method). Three products were used, described as follows: 'NB-PDO drycured ham 24 months ripening – local pig breed in extensive system' (NB24), 'NB-PDO dry-cured ham 36 months ripening – local pig breed in extensive system' (NB36) as innovative TPP to enhance sensory quality, and 'Iberian ham – 50% Iberian pig' (IB) as competing product. Following the expectation disconfirmation theory, the sensory test included three phases: blind (tasting without information), expected (product description only: no tasting) and actual liking (tasting with information), assessed using a 9-point scale from 1: extremely dislike to 9: extremely like. Data were submitted to ANOVA (mixed model). Blind hedonic test showed no differences (P>0.05) between products that all displayed high liking score (6.7 to 6.8). Product description strongly influenced expected liking (P<0.001) with higher score for NB36 than NB24 (7.8 vs 7.2, P<0.05) and lowest score for IB (5.2). Hedonic test with information showed higher actual liking for NB36 and NB24, that were similar, than for IB (7.4 and 7.2 vs 5.9, P<0.001). Both NB hams displayed higher actual than blind liking (P<0.05), denoting positive effect of information on acceptability. Actual liking was similar to expected for NB24, indicating fulfilment of hedonic expectations. By contrast, actual liking was lower than blind for IB (P<0.05). Results will be completed with consumer preferences and willingness to pay for TPP and innovations in TPP. Funded by European Union's H2020 RIA ...

International audience ; In order to further allow implementation of breeding programs in local pig breeds, with selection objectives defined for each local breed, we aimed at developing a standardised recording of carcass and meat quality traits. These data have to be connected with herdbooks to estimate genetic parameters of the traits (heritabilities and genetic correlations) which are necessary to define breeding objectives. Today the situation is very different from one local breed to another. No or very few phenotypes are recorded in some of them, while breeding programs already exist for a few breeds. To promote phenotyping, a dedicated database and a website were developed in the frame of the TREASURE project. First, the required variables have been collected for six local breeds: Basque (FR), Bísaro (PT), Crna slavonska (HR), Gascon (FR), Krškopoljski (SI) and Schwäbisch-Hällisches (DE). In total 74 variables have been identified dealing with animal herdbook information (10), rearing and growth (22), carcass (22) and meat quality (20) attributes. The database is compatible with the various identifiers used in the different countries: animal IDs, breed, farm… codifications. Major attention has been paid to the description of measurement methods of traits. Thus, each carcass and meat quality phenotype is associated to a method description representing 35 additional variables. The website can be easily translated into several languages. The website and database are currently on test until the end of the TREASURE project. All the breeds studied in TREASURE are free to use these tools. The database can be duplicated so that each partner can host its own data. Funded by European Union H2020 RIA program (grant agreement no. 634476).

The aim of the study was to ascertain the acceptability of local pork products by European consumers (blind, expected and informed tests) considering the influence of the sensory properties, the expectations and the information about the product given to them. The consumer tests were performed in four cities following an agreed protocol, with products from local breeds (Negre Mallorquí, Cinta Senese, Gascon-Noir de Bigorre and Turopolje) and included traditional (TPP) and innovative products (ITPP). ; This study received funding from the European Union's Horizon 2020 Research and Innovation programme under grant agreement No 634476 (Project acronym: TREASURE).
