13. Determinação experimental e modelagem de temperatura de ebulição e pH de sistemas binarios contendo compostos presentes em sucos de frutas / Experimental determination and modeling of boiling pont pH of binary systems containing fruit juice compunds
The vapor-liquid equilibrium of binary aqueous solutions of D-glucose and D-fructose, present in fruit juices, was evaluated by experimental boiling point measurements in a rotary evaporator with total reflux of the vapor phase from 20 kPa to atmospheric pressure (93.6 kPa) and concentration from 10 to 60 % by mass. The experimental data were correlated with

14. Conservação refrigerada de lima ácida "Tahiti" em combinação com atmosfera modificada, ácido giberélico e permanganato de potássio / Cold storage Tahiti lime in combination with modified atmosphere, gibberellic acid and potassium permanganate
Although Brazil is the largest producer and exporter of Tahitilime, actually, exports only 5% of total production. This is, in part, because of a lack of quality of these limes, characterized by loss of green skin colour after harvest. The purpose of this research was to evaluate the efficiency of modified atmosphere, gibberellic acid (GA) and potassium perm

15. Alterações fisiológicas e anatômicas causadas por danos mecânicos durante o beneficiamento de maçãs e frutos cítricos / Fisiological and anatomical alterations caused by mechanical damage during apple and citric fruit handeling
Danos mecânicos têm sido responsáveis por grandes perdas de produtos frescos colhidos além de reduzirem a longevidade destes produtos. Este trabalho teve por objetivo medir as forças ocorrentes no embalamento de maçãs e laranjas e identificar os pontos de ocorrência de forças prejudiciais aos frutos. Objetivou-se ainda avaliar os efeitos dos danos m

16. AlteraÃÃes na qualidade da geleia da casca de banana prata durante o armazenamento em diferentes temperaturas / Alterations in the quality of banana peel jelly during the storage under different temperatures
Fruit jellies are very appreciated foods, however the use of the inedible parts of the fruits for their elaboration is not very well known. The banana (Musa acuminata L.) is a fruit of universal consumption, appreciated by people from all classes and of any age, who consume it in natura, fried, baked, cooked, in syrup, in home-made sweets or in industrialize

17. Microbiological evaluation of the juice from different varieties and stalk sections of sugar cane cultivated under organic management / Avaliação dos aspectos microbiológicos do caldo de diferentes variedades e partes do colmo da cana-de-açúcar sob manejo orgânico
For the artisanal cachaça production, which is a beverage obtained after distillation of the fermented sugar cane juice, natural starter ferment (caipira ferment) is utilized, in which crushed corn, rice bran and citric fruit juice are added to sugar cane juice. The primary source of microorganisms, yeasts especially, is the sugar cane juice itself, and alt

18. Avaliação da vida util de manga (Mangifera indica cv Tommy Atkins ) minimamente processada pre-tratada com acido citrico e coberturas comestiveis / Evaluation of the shelf-life of minimally processed mango (Mangifera indica cv Tommy Atkins ) pre-treated with citric acid and edible coatings
Mango is a widely grown and consumed fruit in Brazil, being also exported `in natura¿ to many different countries. Fresh-cut mangoes, in spite of their practicity, may have enzymatic browning and unpleasant changes of texture. Thus, this work aimed to study the shelf-life of mango slices (Mangifera indica cv `Tommy Atkins¿) pre-treated with citric acid and

19. Descascamento de frutas cítricas pelo uso do tratamento hidrotérmico / Peeling of citric fruits by using Hydrothermal Treatment
The citrus fruit processing is justified for the difficulty of peeling of these fruits. Studies of peeling of Perasweet orange fruit accomplished at ESALQ-USP are showing the potential of the use of the hydrothermal treatment to facilitate the peeling of this variety. The oranges are immersed in hot water at 50ºC for 8 minutes. This process to make easy the

20. Evaluation of pre-treatment and application of edible coatings in fruits drying / Avaliação de pre-tratamentos e aplicação de coberturas comestiveis na secagem de frutas
Most vegetables and fruits are highly perishable due to a high water conten, which makes it difficult to trade, since seasonality and distance between markets demand costly refrigerated storage and transportation. Increasing shelf life and availability throughout the year by processing reduces losses by marketing of fresh foods. This research aimed at evalua

21. Comparison of GC and HPLC for quantification of organic acids in two jaboticaba (Myrciaria) fruit varieties
Gas chromatography (GC) with trimethylsilyl derivative formation was compared to high-performance liquid chromatography (HPLC) for quantification of organic acids (OAs) in two jaboticaba (Myrciaria) fruit (pulp and pericarp) varieties (Sabará and Açu Paulista). Succinic and citric acids were the major OAs found in all the samples analyzed. Besides being mu

23. Characterization physicochemical and chemical characterization and study of the enzymatic dark pigment in products derived from aÃaà (Euterpe oleracea Mart.) / CaracterizaÃÃo fÃsico-quÃmica e estudo do escurecimento enzimÃtico em produtos derivados de aÃaà (Euterpe oleracea Mart.)
The aim of this work was to detect oxidative enzyme activities (polyphenoloxidase and guaiacol peroxidase) in pulp, tropical juice and clarified juice of aÃaà fruit as well as to make a physicochemical and chemical characterization in these products. It was used as a raw material for this study type C aÃaà pulp (Euterpe oleracea Mart.) (8% of total solid
