13. Estudos dos processos de hidrolise enzimatica e secagem por atomização para obtenção de hidrolisado proteico de frango em po / Study of the processes of enzymatic hydrolysis and spray drying to obtain a protein hydrolysate of chicken breast meat powder
The present work had as aim to study the processes of enzymatic hydrolysis and spray drying to obtain a protein hydrolysate of chicken breast meat powder. This work was divided into three sections. In the first part, enzymatic kinetics and selection of the best condition of enzymatic hydrolysis, using the commercial enzyme AlcalaseÒ 2.4L, were evaluated. A

14. Partição da extração da água do solo por plantas entre camadas com teores de água distintos / Partition of root water extraction between soil layers with distinct water contents
Water shortage is one of the most limiting factors for agricultural production. The understanding of factors that rule the extraction of soil water by plants and its distribution along the root system under contrasting hydraulic conditions is important for fine-tuning hydrological models which are a reference for crop growth models, meteorological models, am

15. Desenvolvimento de Método Rápido de Análise de Histamina por Cromatografia Líquida de Alta Eficiência em Atum. / Development of Quick Method for Analysis of Histamine in Tuna by High Performance Liquid Chromatography.
Histamine is an important biogenic amine found in fish like tuna, mackerel, bonito and sardines, and in fermented foods like cheese, salami and sauerkraut. Its presence in food should not exceed certain limits, because the intake of this substance in quantities that vary from person to person, can cause scombroid poisoning, whose main symptoms are: abdominal

16. Secagem de sementes de gramíneas (Brachiaria brizantha) em leito fluidizado
Drying operation is an important stage of the processing that precedes the storage of seeds, since that with low moisture contents, these can retain their power of germination and other qualities for long periods. The objective of this work was to perform a study of drying of grass seeds (Brachiaria brizantha) in a batch fluidized bed, in order to evaluate t

17. Estudo da fluidodinâmica e da secagem de um secador rotatório da indústria de fertilizantes
The dimensioning, the modeling and the simulation of the rotary dryers constitutes a big challenge. The drying involves mass and heat transfer, and fluid dynamics processes of the most different forms. Great part of the dryers projects are done according to empiricism and based on the experience of engineers and on the scale-up of prototypes. The purpose of

18. Curvas de retenção de agua de um solo coluvionar de Campinas obtidas mediante tecnicas de laboratorio e de campo / Soil water characteristic curve of a colluvial soil determined by techniques laboratory and field
This research focuses in to determine the relationship of moisture content (or degree of saturation) versus the value of the suction matrix, known as soil water characteristic curve (SWCC), to the soil surface layer of the Field Experimental of Soil Mechanics and Foundation of UNICAMP. This profile consists of colluvial, lateritic, porous, on condition unsat

19. Drying rates in shrinking medium: case study of banana
Drying of foodstuffs is used to improve product stability, but presents some potentially harmful side effects such as shrinkage. The reduction of the relative humidity of the environment was studied in this work to substitute heating during drying, also taking into account the effect on shrinkage. Drying experiments of cylindrical slices of banana were condu

20. Drying in the rotating-pulsed fluidized bed
There are particulate materials that are cohesive when wet. Although they are Geldart's group A dry powders, they show difficulties in fluidizing in a conventional fluidized bed, which could be diminished by modifying the fluidization equipment. Therefore, the objective of this work was to study the drying of cohesive particulate material using a rotating-pu

21. Modeling heat and mass transfer in the heat treatment step of yerba maté processing
The aim of this research was to estimate the leaf and twig temperature and moisture content of yerba maté branches (Ilex paraguariensis Saint Hilaire) during heat treatment, carried out in a rotary kiln dryer. These variables had to be estimated (modeling the heat and mass transfer) due to the difficulty of experimental measurement in the dryer. For modelin

22. A low-cost ultrasonic spray dryer to produce spherical microparticles from polymeric matrices
The spray-drying technique has been widely used for drying heat-sensitive foods, pharmaceuticals, and other substances, because it leads to rapid solvent evaporation from droplets. This method involves the transformation of a feed from a fluid state into a dried particulate, by spraying the feed into a hot medium. Despite being most often considered a dehydr

23. Produção de extratos secos padronizados de plantas medicinais brasileiras: estudo da viabilidade técnica e econômica do processo em leito de jorro / Standardized dried extracts of Brazilian medicinal plants: assessment of technical and economical feasibility of the spouted bed drying
The aim of this work was to investigate the technological and economical feasibility of the spouted bed drying process for production of the standardized dried extracts of Brazilian medicinal plants using the Bauhinia forficata Link as an experimental model. The objective was to demonstrate the potential of this technology for the processing of medicinal pla

24. Avaliação da secagem, torrefação e estabilidade da castanha de pequi (Caryocar brasiliense Camb.) / Evaluation of drying, roasting chestnuts, and stability of pequi (Caryocar brasiliense Camb.)
Pequi (Caryocar brasiliense Camb.) possesss in its interior eatable chestnut little explored. In this study it was objectified to evaluate the drying process, toasting and the stability of the chestnut during 180 days in three different packings. Seeds supplied for the Association of Improvement of Fruits of the Open pasture, located in the city of Damianóp
