Resumen
In recent years, farmers in the Northwest of Paraná has been cultivating the
coconut tree, seeking commercialization of water of the green fruit. In literature
there are few reports on production and quality of coconut in the region, because
they are few producers who were motivated to produce fruit. In order to
investigate the quality of coconut water and fresh fruit was produced this work.
The fruits, cv. Dwarf Green, were collected from the Umuarama and Cidade
Gaúcha cities, located in Northwest region of Paraná, in the four seasons and five
stages. The evaluated fruit physical and chemical, biochemical and sensory
characteristics of fresh coconut water. The results were evaluated by analysis of
variance and means compared by Tukey test (p <0.05). The values of the climatic
stations were evaluated with few variables outside of what the culture needs for
production. The results indicated that the fruits showed an increase in fruit size
and weight and volume of water, as increased time of fruit development in all
seasons. The physical-chemical aspects indicate difference between the samples
taken between seasons. The mass and size of coconuts and coconut water volume
increased with increasing time of development, in all seasons in both locations.
Turbidity statistical difference between the fruits, presenting the best value for
water extracted fruit with five and six months of production Umuarama. The
chemical composition indicates that coconut water collected after the winter
season in both locations, have lower specifications in some parameters, in
relation to water from fruits harvested at the end of the other stations. The
enzyme activity had increased as increasing stage of fruit development. Sensory
evaluation indicated better acceptance of the fruit of the fruits of seven months.

The acceptance of coconut water showed significant differences between the time
of harvesting for the production of both cities, especially those harvested in late
summer and spring. Despite the climate of the region evaluated undergo several
changes during the year, with stations that have high variation in climatic
conditions, and these may influence the production of coconut, fruit quality for
the consumption of coconut water is approaching the fruits produced in the
tropical regions.
