Jenkinson, William. "Simulation de la mécanique mésoscopique des aliments par méthodes de particules lagrangiennes". Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASB047.
Testo completoThe role of mesoscopic mechanics in food processing and design is not well understood, particularly for oral processing and texture perception. Despite the recognized importance of soft matter, the food science community has struggled to bridge the gap between micro-, meso-, and macro-scale behaviours using simulations. This thesis addresses this challenge by focusing on mechanical simulations, excluding thermal, chemical and physicochemical effects, to explore food behaviour at the mesoscopic scale. We have developed a simulation framework within the LAMMPS environment, combining smoothed-particle hydrodynamics (SPH) implementations for liquids and elastic solids. We validated the framework across scenarios such as Couette flow and deformation of granules in a flow. The results show the framework's effectiveness in capturing food structure dynamics and interactions with cilia and papillae and offer new insights into texture perception and hydrodynamics. The study also highlights how granule elasticity and volume fraction impact flow properties and their eventual role in texture perception. This work focuses on mechanics while deliberately remaining flexible enough to integrate mechanical, thermal, chemical, and biological processes in future food science models. Proposed future research includes strategies to integrate more physics and scales and efforts to improve the accessibility of simulation tools for engineers, advancing practical applications in food science

Testo completoUnderstanding and modeling phenomena governing stimuli release during food consumption make it possible to respect both nutritional and sensorial criteria during its formulation. A model of salt release during the course of mastication was developed for “solid” products. The breakdown was comprehended by the generation of the area of contact between the product and the saliva that governs the transfers of stimuli. The area of contact was written as the product of two functions. The first was related to the subject and was function of his masticatory performance. The second was related to the product and depended on its breakdown behavior that can be determined by in vitro tests. During the pharyngeal stage, the biomechanics of swallowing governs pharyngeal mucosa coating and aroma compounds present in this layer. These phenomena are due to a thin film flow, stationary in a soft elastohydrodynamic contact whose the kinematics is equivalent to a forward roll coating process lubricated by saliva. Two sets of conditions were distinguished. When the saliva film is thin, food bolus viscosity has a strong impact on mucosa coating and on flavour release. When the saliva film is thick, the food bolus coating the mucosa is very diluted by saliva during the swallowing process and the impact of product viscosity on flavour release is weak. This second set of condition allowed us to explain the physical origin of in vivo observations on flavour release

Testo completoThe EU directive 1935/2004/CE compels the traceability of contaminants originating from food contact materials. Stakeholders must verify possibly with simulation that desorbed substances from packaging materials do not exceed specific migration limits. No general model exist to predict diffusion coefficients, D, ands their activation energies, Ea, in thermoplastics. This work studies the molecular transport mechanisms of additives-type molecules (MAT) in polyolefins, and the responsability of entropic trapping for the high spread of D and Ea values. The analysis rely on experimental data (D, Ea), which were available before this study, and on data collected during this study (activation volumes, Va), as well as on simulations of molecular mechanics and non-equilibrium dynamics. Scaling laws of type D proportional to the molecular mass with a power α>1,8 and simulations confirm that the geometrical confinement between polymer segments is the factor which limits the diffusion. The translation process of MAT occurs by successive reorientations of a fraction of their length along the direction of minimum section. Ramifications and symmetry decrease the diffusion process. The description of diffusion of MAT as random walks between macro-states was used to propose molecular descriptors to classify and predict D values in polyolefins. With a probabilistic framework, the proposed method based on decision trees generates likely or overestimates of D values. A microscopic method of local measurement of D and Ea values has also been developed to consider the semi-crystalline state of polyolefins at ambient temperature

Testo completoIn this work, a system that allows obtaining dynamic images of temperature fields from a set of 19 electrical property measurements of the agitated fluid via a number of electrodes which are mounted non-intrusively on the vessel boundary has been developped. Using this system, it was shown the existence of thermal gradients within the vessel. In the same time, the developed tool permits to appreciate structural heterogeneity of texturing foods during cooking from a detection algorithm based on the log-likelihood ratio and applied on the first derivative of the delivered electrical signal. Experimental studies were performed with model fluids, simulating the behavior of real food fluids. That was necessary in order to be freed from the seasonal variations of real foods and to be able to discuss the physical phenomena observed during cooking of such fluids

Testo completoThe purpose of this thesis is to put forward an original structuring of an Interactive Decision Support System (IDSS) applied to the management control of the production system in food industries. A study of the food industry was carried out using a systemic approach that makes reference to a multi-criteria vision of the performance suggested by Kaplan and Norton in their balanced scorecard. With this empirical approach, a representation of the causality relations between various industrial performance indicators was proposed, thus formalising a global influence diagram corresponding to the structural base of the suggested system dynamics generic model. It is within this theoretical framework and the particular field of application that we chose and proposed a continuous simulation model which, from initial values of performance indicators, is able to simulate the possible evolutions in the behaviour of these particular production systems, and consequently, evolutions of these same indicators. This IDSS will allow to forecast the evolution of performance indicators while being based on their causal and dynamic interdependence, thus being different from the traditional forecast methods based on past chronological series

Testo completoSelf-regulation is an essential resource for not succumbing to (junk) food. It requires willpower and control of emotions and sensations. However, individuals operate in an environment enhancing food pleasure where health informations are few and poorly considered, causing difficulties in self-regulation. These difficulties are found especially in overweight people and/or dieter. We hypothesized that value the taste of healthy foods could help people to self-regulate and we conducted two experiments to test it. In the first study, messages highlighting the pleasure of eating fruits and vegetables are more persuasive to subjects taking risks to health. Similarly, in the second study in decision making, focusing on the tatste of these foods increases more healthy food choices for these subjects. By using neuroimaging, we have shown brain activity distinctions between these subjects when choosing healthy food in this condition. Choosing healthy food is more impulsive for the most sensitive to reward subjects, approaching the choice of junk foods. Instead, it appears more reflective for subjects with a high BMI and choosing more junk foods, facilitating self-regulation. At the theoretical level this research highlights the positive role of emotions and sensations related to pleasure in self-regulation. At the managerial level, it suggests the importance of adapting strategies to the target audience in order to efficiently healthy food consumption
