1. Oxidative processes during 'Golden' papaya fruit ripening
'Golden' papayas at maturity stage 1 (15% yellow skin) were chosen to study selected oxidative processes, the activity of antioxidant enzymes and lipid peroxidation in storage at 22°C, during the ripening of the fruit. An increase in ethylene production was observed on the second day of storage and it was followed by an increase in respiration. An increased

2. Sequence similarity between the viral cp gene and the transgene in transgenic papayas.
The Papaya ringspot virus (PRSV) coat protein transgene present in 'Rainbow' and 'SunUp' papayas disclose high sequence similarity (>89%) to the cp gene from PRSV BR and TH. Despite this, both isolates are able to break down the resistance in 'Rainbow', while only the latter is able to do so in 'SunUp'. The objective of this work was to evaluate the degree o

3. Caracterização e comparação de sistemas de embalagem e transporte de mamão Solodestinado ao mercado nacional. / Characterization and comparison of packaging and transport systems of Solo papaya fruits for the domestic market.
The aim of this work was to characterize packaging and transport systems of Solo papaya fruits for the domestic market, and compare them each other, evaluating their consequences in postharvest performance of the papaya transportation from the local production to the wholesale market. A study was carried out in CEAGESP (Companhia de Entrepostos e Armazéns G

4. Quality of papaya submitted to 1-MCP in different exposition times. / Qualidade de mamÃo submetido ao 1-MCP em diferentes tempos de exposiÃÃo.
The papaya is a climateric fruit the transformations of which resulting from ripening occur rapidly after the collection of the physiologically mature fruit, triggered by ethylene production and increased respiratory rate. That characterizes it as a quite perishable fruit after collection. Given to that high perishibility, ripening control is fundamental to

5. Métodos combinados para preservar a qualidade pós-colheita do mamão Goldentipo exportação / Hurdle technology to preserve the Goldenpapaya postharvest quality
With the purpose of evaluating a combination of postharvest techniques on papaya Golden storage, the following treatments were investigated: carton boxes packaging (CP); CP + plastic bag of PEBD - low density polyethylene film, with 0.05mm of thickness (PE); CP + PEBD with 0.025mm of thickness impregnated with mineral ethylene scavenger (PEAbs); y-irradiatio

6. Ripening of Golden papaya fruit: harvest time, ethylene action blockade and cold storage / Amadurecimento do mamão Golden : ponto de colheita, bloqueio da ação do etileno e armazenamento refrigerado
The present work had as objective the study of how the harvest time, ethylene action blockade and cold storage influence the ripening and the quality of Golden papaya fruit. In the first experiment Golden papayas were harvested at 4 maturity stages (Stage 0: totally green; Stage 1: up to 15% of yellow skin; Stage 2: 16-25% of yellow skin; Stage 3: 26

7. Estudo do processo de secagem de mamão formosa (Carica papaya L.) fresco e pre-tratado osmoticamente. / Study of drying process of fresh and osmotically pre-treated papaya (Carica papaya L.).
The present work had as objective to study the drying process of fresh and pretreated papaya (Carica papaya L.). Two osmotic agents were used: sucrose and corn syrup. The osmotic dehydration process was studied by an experimental design, with the temperature (30 - 50oC) and concentration (40 - 60% w/w) of the osmotic solution and the immersion time (90 - 240

8. Estudo da desidratação osmotica com aditivos e do acondicionamento sob atmosfera modificada de pedaços de mamão formosa / Study of osmotic dehydration with additives and of the packaging under modified atmosphere of Formosa papaya pieces.
Modern life style, allied to an interest for a healthy diet, has been causing a market demand for fresh-like foods, ready for consumption and convenience. In response to this demand the food industry promoted the development of mild processes and technologies, aiming to maintain product final quality and increase its resistance to degradation. Papayas from t

9. Disponibilidade de carotenoides em relação a energia e proteinas nos domicilios de familias das regiões metropolitanas brasileiras
This work analyzed the availability of the carotenoids to the consumers of eleven major Brazilian urban centers -nine metropolitan regions and two cities, especially with regard to energy and protein availabilitybased on the data gathered by the POF (Household Budget Survey) 1995-1996. The USDA database - release 14 was used to determine composition of energ
