15. Sucos de laranja : abordagem química, física, sensorial e avaliação de embalagens
Oito amostras comerciais de suco adoçado e néctar de laranja foram analisadas quanto às características físico-químicas e quanto à aceitação, por 101 consumidores. Constatou-se que as amostras apresentavam conformidade com a legislação vigente para os parâmetros físico-químicos. Os dados de aceitação foram analisados por ANOVA, teste de Tukey

16. Effect of different citrus aromas on sensory quality and stability of ready-to-drink orange juice. / Efeito de diferentes aromas citricos sobre a qualidade e estabilidade sensoriais de suco de laranja pronto para beber.
Para a recuperação do aroma e sabor de fruta fresca ao suco industrializado, subprodutos do processamento do suco de laranja, como óleo essencial e essências aquosa e oleosa, são normalmente reincorporados ao produto processado. A adição de cada um desses subprodutos confere ao produto final qualidade e estabilidade sensoriais distintas. O presente tr

17. Post-harvest citrus diseases: Potential of the Lentinula edodes, Agaricus blazei, jasmonic acid, mesocarp (Citrus sinensis var. Valência) and epicarp (Citrus aurantifolia var. Tahiti) in the control and in the resistance induction / Doenças pós-colheita em citros: potencial do Lentinula edodes, Agaricus blazei, ácido jasmônico, albedo (Citrus sinensis var. Valência) e flavedo (Citrus aurantifolia var. Tahiti) no controle e na indução de resistência
Brazil is considered the biggest citrus producer and the biggest orange juice exporter. Post-harvest diseases represent a great loss in the citriculture, and for many fruits to be exported they should be free of chemical residues. In relation to some pathogens of importance in post-harvest it can be mentioned Guignardia citricarpa (black-spot-ofcitrus), Peni

18. Estudo do processo de liofilização : aplicação para suco de laranja / Freeze drying process study: application for orange juice
Freeze drying is a separation process based on sublimation phenomenon. Due to the absence of liquid water and the low temperature required for the process, most of deterioration and microbiological reactions are stopped which gives a final products of excellent quality. The fundamental stages involved in freeze drying process are: freezing, primary drying st

19. Honey bee attractants and pollination in sweet orange, Citrus sinensis (L.) Osbeck, var. Pera-Rio
This experiment studied the frequency and behavior of insects on sweet orange flowers, Citrus sinensis (L.) Osbeck, their effect on fruit production (quantity and quality), nectar and pollen collection, and the effectiveness of different attractants. Over three consecutive years, the most frequent visitor to the flowers was Apis mellifera (Africanized). Flow

20. Boron fertilization in pêra rio sweet orange affected by citrus variegated chlorosis. / Adubação boratada em pomar de laranja Pêra Rio afetado pela clorose variegada dos citros.
Citrus crop is extremely dependent on an adequate mineral nutrition to reach bigger levels of production to fewer costs, especially under adverse conditions, as in the case of occurrence of citrus variegated chlorosis (CVC). In this context, boron directly influences the production because it provides a bigger root growth, what increases the volume of the ex

23. Desenvolvimento de metodologias analiticas utilizando espectroscopia visivel e infravermelho proximo
This work describes the development of analytical methodologies using visible and near infrared spectroscopy. In the visible range a new method for determination of color index of sugars (ICUMSA) produced for exportation was developed. Secondarily, a multi- channel spectrophotometer was constructed employing a diode array detector EGG-Reticon - RL 1024. The
