Zweinutzungshuhn – wie schmeckt das? Sensorische Beurteilung von Hühnerfleisch und Eiern von vier Zweinutzungshuhn-Genetiken
(2023) Gebhardt, Beate; Maute, Jutta; Kiefer, Lukas
Research into the sensory properties of meat and eggs from dual-purpose chickens has so far been a niche from a scientific point of view. In cooperation with the EIP-Agri project "ZweiWert", students at the DHBW Heilbronn therefore tasted, analysed and evaluated several dual-purpose chicken genetics in the integration seminar "Dual-purpose chickens: How to communicate the added value" in summer 2023. The genetics “Coffee" from the Ökologische Tierzucht (ÖTZ), "Sundheimer" from the Öko2Huhn project, "RegioHuhn" and "Lohmann Dual" as well as a control group from a classic laying or fattening line were assessed. The aim was to find out how different dual-purpose chickens taste and whether there are sensory differences or special features in meat and eggs Sensory attributes, including appearance, taste and smell, were recorded using a multi-methods assessment sheet. In short, the results of this explorative study show that dual-purpose chickens taste better. However, according to the testers judgement, there are differences not only between the different genetics, but also between the individual parts - breast, drumstick, wings or broth. The sensory profiles of the four dual-purpose chickens tested are varied and do not allow a clear sensory "ranking". The meat from Lohmann Dual apparently corresponds best to consumer preferences, while their eggs (cooked) are the least appealing. Overall, however, there is a consistent sensory superiority of the dual-purpose chickens over the specialised fattening or laying breed. These results - should they be confirmed in further studies - could contribute to increasing consumer acceptance of dual-purpose chickens and addressed in market communication to their further spread. The EIP project titled "Building Value Chains for Dual-Purpose Chickens in Baden-Württemberg" (ZweiWert) is funded by the Ministry of Food, Rural Areas and Consumer Protection of Baden-Württemberg from 01/2022 to 12/2024. Project partners include the Naturland Association of Baden-Württemberg, several departments of the University of Hohenheim, and many partners from agricultural production and marketing.
