In the valorisation of fruit and vegetable by-products by high pressure homogenization (HPH) into texturizing ingredients, source by-product is an important determining factor. This study aims to demonstrate potential citrus residues after acidic pectin extraction (AR) investigate differences between species (lemon, orange, grapefruit) parts (peel pulp) as residues. Based on results, favourable...

OBJECTIVES In the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (SLN)-safranal formulations were evaluated. MATERIALS AND METHODS Series of SLN were prepared using glyceryl monostearate, Tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (HPH) methods. SLN formulations were characterized f...

We analyze two-phase flow in highly heterogeneous media. Problems related to the degeneracy of the permeability coefficient functions are treated with a new concept of weighted solutions. Instead of the pressure variables we formulate the problem with the weighted pressure function ψ, which is obtained as the product of permeability and pressure. We perform the homogenization limit and obtain e...

Introduction:Severe abdominal aortic constriction above the renal arteries induces arterial hypertension above the stenotic site that is the cause of cardiac hypertrophy. Previous studies have shown that high blood pressure induces myocardial oxidative stress with conflicting results. In the present study, we assessed the effects of acute hypertension on the myocardial oxidative stress an...

This experimental work aimed to evaluate the potential of high pressure homogenization (HPH) to inactivate Saccharomyces cerevisiae 635 inoculated both in apricot and carrot juices. The sensitivity of the yeast was evaluated both in relation to its initial inoculum level (about 3.0 and 6.0 Log(10) cfu/ml) and number of passes applied at 100 MPa. Moreover, the effects of repeated pressure treatm...

Specially engineered drug particles can solve solubility and formulation problems, which are major challenges for the pharmaceutical industry. Particle size reduction of poorly water soluble drugs results in increased dissolution rate and higher bioavailability or better processability as demonstrated in previous studies [1, 2]. High-pressure homogenization can be used to decrease particle size...

Homogenization has proved its effectiveness as a method of upscaling for linear problems, as they occur in single-phase porous media flow for arbitrary heterogeneous rocks. Here we extend the classical homogenization approach to nonlinear problems by considering incompressible, immiscible two-phase porous media flow. The extensions have been based on the principle of preservation of form, stati...
