1. WATER VERSUS LACTOSE SOLUTION AS A DISPERSION MEDIUM FOR PARTICLE ANALYSIS IN SWEETENED CONDENSED MILK BY LASER DIFFRACTION
Sweetened condensed milk contains various dispersed particles, such as proteins, fats, and lactose, all of which make it highly viscous. During sweetened condensed milk production, microcrystalline lactose is added in order to control the product crystallization. The purpose of this study was to characterize the behavior of commercially sold sweetened conden

2. Coupled monolithic columns as an alternative for the use of viscous ethanol–water mobile phases on chromatographic fingerprinting complex samples
ABSTRACT Concepts of sustainability have received attention from people involved in investigation of nature-derived matrices. The effects of concomitant pollutant activities are cumulative and harmful to the environment from which these matrices are obtained. High performance liquid chromatography analyses generate millions of litters of chemical waste world

3. Green tea glycolic extract-loaded liquid crystal systems: development, characterization and microbiological control
ABSTRACT Liquid crystal systems (LCSs) have interesting cosmetic applications because of their ability to increase the therapeutic efficiency and solubility of active ingredients. The aim of the present research was to develop green tea glycolic extract-loaded LCSs, to characterize and to perform microbiological control. The ternary phase diagram was constru

4. Management of freezing rate and trehalose concentration to improve frozen dough properties and bread quality
Abstract Bread is one of the most consumed foods in the world, and alternatives have been sought to extend its shell life, and freezing is one of the most popular methods. The purpose of this study was to evaluate the effect of freezing rate and trehalose concentration on the fermentative and viscoelastic properties of dough and bread quality. Dough was prep

5. Viscoelastic Behaviour Characterization of a Gap-graded Asphalt Mixture with SBS Polymer Modified Bitumen
A characterization of the linear thermo-viscoelastic behaviour of a gap-graded bituminous mixture with SBS-polymer modified bitumen and RAP aggregates is presented in this paper. A comparison was made, in terms of their viscoelastic behaviour, between this innovative mixture and two commonly used well-graded base-course French mixtures made with pure bitumen

6. Nanocompósitos de borracha nitrílica com argilas montmoriloníticas e bentonitas / nonoonono
The search for new materials has been a constant in the humanity history. However, there are no plans to replace elastomers, even in long term, due to their unique mechanical properties. Among the various types of elastomers used nowadays, Nitrile Butadiene Rubber - NBR is a choice when one wants a material with good mechanical properties and excellent resis

7. Estudo comparativo de colágeno hidrolisado e comercial com adição de PVA / Comparative study of commercial and anionic collagen blended with PVA
The development of new materials has been based on the mix of two or more polymers or biopolymers where solutions are mixed in different portions trying to get materials with distinct properties from their precursors. In this work different collagen solutions and collagen-PVA blends were analyzed. The used collagen was the type I, however obtained from two d

8. Avaliação de géis obtidos a partir da acetilação da quitosana em meio heterogêneo
Chitosan was acetylated during 2, 5 and 10h and physical gels were obtained at different polymer concentrations in N,N-dimethylacetamide containing 5% of LiCl. Acetylation was confirmed by infrared spectroscopy and 13C NMR, and degrees of acetylation in the range of 0.82-0.91 were determined by NMR. The O-acetylation degree (0.12-0.15) was exclusively determ

9. InovaÃÃo tecnolÃgica baseada na produÃÃo de biopolÃmero com viabilidade para inoculante rizobiano
The biopolymers are polysaccharide from microbial origin, synthesized by bacteria, fungi and yeast. They are also known as gums due to their capacity to produce viscous solutions and gel in an acquoso medium. The production of microbial Exopolysaccharide (EPS) has been an object of intensive research, due to its high application and potential in different fi

10. Rheological and thermal behavior of amaranth starch-sodium caseinate systems : effect of sugar addition and acidification time / Comportamento reologico e termico de sistemas amido de amaranto-caseinato de sodio : efeito da adição de açucar e tempo de acidificação
The starches are frequently added to the foods owed their properties and water retention, as colloidal emulsion-estabilizing agents. The amaranth is a low cost culture, and his starch, a new ingredient with potential industrial use. The caseinato of sodium is a salt derived of the casein thoroughly used as emulsion in foods. The study proteins and polysaccha

11. Estudo da fotodegradação de petróleo por ressonância paramagnética eletrônica
Paramagnetic species have been found in the Brazilian Petroleum (BP) and Arabian Light (AL) by means of EPR, before and after irradiation. Two oil samples are of the AL petroleum, a crude oil called Total Arabian (TA) and an other sample distilled at 260oC, called Partial Arabian (PA). The BP was used in the crude form without treatment. Three oil sa

12. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS PARA DETERMINAÇÃO DE ELEMENTOS-TRAÇO EM AMOSTRAS OLEOSAS E PASTOSAS POR ICP OES E ICP- MS / DEVELOPMENT OF ANALYTICAL METHODS FOR TRACE ELEMENTS DETERMINATIONS IN OILY AND VISCOUS SAMPLES BY ICP OES E ICP-MS
Métodos de análise para determinação de elementos-traço em amostras oleosas e pastosas são necessários, por exemplo, no caso do petróleo e em suas frações mais pesadas, para os quais os elementos-traço indicam características do tipo do petróleo, correlacionando-o com a localização geográfica da jazida. Além disso, a quantificação destes e
