BACKGROUND: The food industry has shown an increased interest in the manufacture of healthier and more natural products. By tailored processing fruit vegetables can be used as structurants thus reducing artificial gums stabilisers. effect different thermal mechanical treatments, including high-pressure homogenisation, on microstructural rheological properties carrot, broccoli tomato dispersions was studied. As part characterisation small oscillatory deformation well shear flow measurements...
Abstract: High‐pressure homogenization, as a way to further mechanically disrupt plant cells and cell walls compared conventional blending, has been applied thermally treated comminuted carrot tomato material in the presence of 5% olive oil. Mixes both vegetables 1:1 ratio were also included. Both effect homogenization pressure multiple process cycles studied. The different microstructures generated linked rheological properties analyzed by oscillatory steady state measurements. results...
Abstract: The correlation between food microstructure and in vitro bioaccessibility of carotenes was evaluated for tomato carrot emulsions (5% olive oil) subjected to high pressure homogenization (HPH) at varying degrees intensity. aim investigate whether additional mechanical disruption the matrix could be utilized further increase carotene an already pre‐processed material. samples measured after simulated digestion, release oil phase estimated by Confocal Raman spectroscopy and, measure...
This study explores the cascade extraction of polyphenols and pectins from apple pomace their potential application as food emulsifiers. The was achieved by a simple method using ethanol resulted in remarkable antioxidant activity. Pectic polysaccharides were sequentially extracted (5, 10 15 min) subcritical water at two different temperatures (120 °C 140 °C) three pH conditions (pH 3.0, 5.0 7.0). Acidic higher pectin yields when combined with temperature, whereas neutral less selective...
The micromechanics of cellulose hydrogels have been investigated using a new rheological experimental approach, combined with simulation poroelastic constitutive model. A series mechanical compression steps at different strain rates were performed as function hydrogel thickness, small amplitude oscillatory shear after each step to monitor the viscoelasticity sample. During compression, bacterial behaved anisotropic materials near zero Poisson's ratio. altered water was squeezed out...
Hemicelluloses exhibit a range of interactions with cellulose, the mechanical consequences which in plant cell walls are incompletely understood. We report properties wall analogues based on cellulose hydrogels to elucidate contribution xyloglucan or arabinoxylan as examples two hemicelluloses displaying different cellulose. subjected pressures emulate compressive stresses experienced by planta. Our results revealed that presence either hemicellulose increased resistance compression at fast...
Preparation of a bolus is complex process with both food comminution and degree lubrication saliva playing an important role in safe swallow.
Feruloylated arabinoxylan (FAX) from cereal brans has large potential to generate multifunctional materials with customized macromolecular and nanostructural architectures techno-functional properties. Here we investigate the chemical structural mechanisms of hydrogel formation wheat bran FAX following enzymatic crosslinking by laccase a subsequent regeneration procedure involving freeze-drying resuspension crosslinked in different pH buffers, using battery biochemical, rheological physical...
