Food Rheology
نویسنده
چکیده
Food includes a wide range of biological materials with diverse rheological character. They are mostly a mixture of different structures previously treated in this book: emulsions, suspensions, foams, gels, solutions and melts. This means that the food rheologist deals with complex fluids which often are substantially inhomogeneous. The variability in the biological food systems is large in contrast to synthetic, well characterized systems, and is an effect of cultivation conditions, species variations, processing and recipe. Nevertheless, rheological characterization is an important tool for development, optimization and processing of foods.

Effect of a functional food (vegetable soup) on blood rheology in patients with polycythemia
Objective: Key hemorheological variables are associated with several life-threatening diseases including cardio-cerebro-vascular diseases. A diet can influence the blood rheological variables. To compare the effectiveness of a vegetable soup on blood viscosity (BV), hematocrit (Hct), plasma fibrinogen, lipid profile, fasting blood sugar (FBS), and blood osmolarity in patients with polycythemia ...
متن کاملFood oral processing—A review
Food oral processing is an essential procedure not only for the consumption and digestion of foods but also for the appreciation and pleasure of food texture and food flavour. The consumption of a food inside mouth involves various oral operations, including first bite, chewing and mastication, transportation, bolus formation, swallowing, etc. Exact mechanisms and governing principles of these ...
متن کاملInfluence of hydration and starch digestion on the transient rheology of an aqueous suspension of comminuted potato snack food.
Oral processing of most foods is inherently destructive: solids are broken into particles before reassembly into a hydrated bolus while salivary enzymes degrade food components. In order to investigate the underlying physics driving changes during oral processing, we capture the transient rheological behaviour of a simulated potato chip bolus during hydration by a buffer with or without α-amyla...
متن کاملRheology of Food Dispersions
We review the viscous and viscoelastic behaviours of concentrated food emulsions and plant food suspensions. Special attention has been given to the influence that food processing exerts on the rheological characteristics of the abovementioned foodstuffs.
متن کاملEffect of extraction rate on rheological properties of wheat flour
The effect of different extraction rates (64%, 82% and 90%) of wheat flour on the rheological properties of the wheat flour dough was investigated. A complete study of the rheological behavior of the wheat flour dough was performed by using three different instruments namely alveograph, extensograph, and farinograph. The correlation coefficient among the various parameters of applied methods wa...
متن کاملEdible oleogels based on water soluble food polymers: preparation, characterization and potential application.
Oil structuring using food-approved polymers is an emerging strategy and holds significant promise in the area of food and nutrition. In the current study, edible oleogels (containing >97 wt% of sunflower oil) were prepared using a combination of water soluble food polymers (methylcellulose and xanthan gum) and further evaluated for potential application as a shortening alternative. Microstruct...
