Abstract

Fats and oils are bioproducts of great industrial and nutritional relevance, due to their sensorial contribution to food products and as an important energy source for human nutrition. However, the excessive consumption of them is directly related to several alimentary diseases, such as arteriosclerosis and obesity. In this context, computational predictive tools are of great importance for developing "tailor made" food products in order to attend specific nutritional demands, reducing products development costs, and supporting digestibility in vitro and in vivo simulations. In this context, and taking into account the lack of efficient models to predict the physical properties of food systems, this work is aimed at evaluate and develop methodologies for calculating physical properties, phase equilibrium and describe the fluid dynamics of fats and oils during the digestive process. This work is organized in 3 steps: i) Obtainment of experimental data for solid fat content curves and rheological profiles, and development of methodologies for prediction of viscosity and solid fat content of fats and oils; ii) development of methodologies for prediction of the solid content and pH of the gastric environment, after the ingestion of fats and oils, including the validation of the results by using the in vitro digestion simulation protocol, and iii) simulation of the fluid dynamic profile of fats and oils during the digestive process. This work will be focused in vegetable oils, animal and vegetable fats, widely used in food and pharmaceutical industries, with special target in the matrices from the Brazilian Biodiversity, whose information are scarce in literature. The results obtained in this work will be used to: a) implementation of an experimental data bank of physical and equilibrium properties of fats and oils; b) evaluation of the existing methodologies and development of new approaches to predict solid fat curves and viscosity, potentially used for product formulation and digestibility studies; c) implementation of an computational algorithm integrating the calculation of physical properties of fat and oils by using only their triacylglycerol composition; d) development of approaches for evaluation of the fluid dynamic profile of fats and oils during the gastric step of the digestive process, with the main focus on fats and oils of medium chain (whose majority digestion occurs in this stage).
