Oral processing, rheology, and mechanical response: Relations in a two‐phase food model with anisotropic compounds
(2023) Oppen, Dominic; Weiss, Jochen
Food‐material poses a challenging matrix for objective material scientific description that matches the consumers' perception. With eyes on the emerging structured food materials from alternative protein sources, objectively describing perceived texture characteristics became a topic of interest to the food industry. This work made use of the well‐known methodologies of jaw tracking and electromyography from the field of “food oral processing" and compared outcomes with mechanical responses to the deformation of model food systems to meat alternatives. To enable transferability to meat alternative products, an anisotropic structuring ingredient for alternative products, high‐moisture texturized vegetable protein (HM‐TVP), was embedded in an isotropic hydrocolloid gel. Data of the jaw movement and muscle activities exerted during mastication were modeled in a linear mixed model and set in relation to characteristic values obtained from small‐ and large‐strain deformation. For improvement of the model fit, this work makes use of two new data‐processing strategies in the field of oral processing: (i) Muscle activity data were set in relation to true forces and (ii) measured data were standardized and subjected to dimensional reduction. Based on that, model terms showed decreased p‐values on various oral processing features. As a key outcome, it could be shown that an anisotropic structured phase induces more lateral jaw movement than isotropic samples, as was shown in meat model systems.
Plant-based foods for future. Results of consumer and professional expert interviews in five European countries - EIT-Food Project „The V-Place“
(2020) Gebhardt, Beate; Hadwiger, Klaus
This working paper documents the methodology of the qualitative studies and the resulting insights, as part one of the two-stage study of the Project „The V-Place - Enabling consumer choice in Vegan or Vegetarian food products“ in six European countries. The interviews with 70 consumers and professional experts in total has already been completed. Still in 2020, a quantitative consumer survey will be conducted in Germany, Denmark, France, Italy, Spain and Poland. The project is led by the Hohenheim Research Center for Bioeconomy, University of Hohenheim. The Department of Agricultural Markets at the University of Hohenheim is responsible for the qualitative studies. This project is funded by EIT Food, the Food Innovation Community of the European Institute of Innovation and Technology (EIT). EIT is an EU institution under Horizon 2020, the EU Framework Programme for Research and Innovation.
