1. Micronization and extrusion processing on the physicochemical properties of dietary fiber
RESUMO: A fibra alimentar desempenha importante papel fisiológico, o qual está diretamente ligado às suas propriedades físico-químicas de capacidade de retenção de água, ligação ao óleo e a cátions. Estas propriedades podem ser alteradas empregando-se métodos enzimáticos, químicos e físicos. Métodos enzimáticos e químicos requerem solvent

2. THE EFFECT OF SYSTEM TEMPERATURE AND PRESSURE ON THE FLUID-DYNAMIC BEHAVIOR OF THE SUPERCRITICAL ANTISOLVENT MICRONIZATION PROCESS: A NUMERICAL APPROACH
Abstract The Supercritical Antisolvent (SAS) technique allows for the precipitation of drugs and biopolymers in nanometer size in a wide range of industrial applications, while guaranteeing the physical and chemical integrity of such materials. However, a suitable combination of operating parameters is needed for each type of solute. The knowledge of fluid d

3. Chemical composition and effects of micronized corn bran on iron bioavailability in rats
The degermination of corn grains by dry milling generates 5% of a fibrous residue. After segregation and micronization, corn bran becomes a potential source of dietary fiber consumption. However, its effect on iron bioavailability has not been reported in the literature. The objective of the present study was to determine the nutritional composition of corn

5. Extração, micronização e estabilização de pigmentos funcionais : construção de uma unidade multipropósito para desenvolvimento de processos com fluídos pressurizados / Extractionm micronization and stabilization of functional pigments : construction of multipurpose unit for pressurized fluid process development
The food industry is continuously searching compounds that present physical and chemical properties to improve their products. Most of them are additives with antioxidant properties, colorants or additives with positive effects to human health. Natural additives are always preferred to synthetic compounds. Flavonoids and carotenoids are two of the major func

6. Low-temperature micronization of a peptide drug in fluid propellant: Case study cetrorelix
Aim of this study was to elaborate an efficient method for the micronization of the decapeptide cetrorelix (a GnRH-antagonist), in order to obtain a microsuspension as basis for other pharmaceutical preparations, such as e.g. inhalation aerosols. A modified pearl-mill coupled with a cryostat was used for the micronization of cetrorelix in fluid propellant an

7. Liposomal dry powders as aerosols for pulmonary delivery of proteins
The purpose of this research was to develop liposomal dry powder aerosols for protein delivery. The delivery of stable protein formulations is essential for protein subunit vaccine delivery, which requires local delivery to macrophages in the lungs. β-Glucuronidase (GUS) was used as a model protein to evaluate dry powder liposomes as inhaled delivery vehicl

8. Production of cromolyn sodium microparticles for aerosol delivery by supercritical assisted atomization
The purpose of this study was to produce cromolyn sodium (CS) micrometric particles with controlled particle size (PS) and PS distribution (PSD) suitable for aerosol delivery, using a supercritical fluids-based process. CS was micronized using the supercritical assisted atomization (SAA) technique at different solute concentrations in water and different pre
