Caracterização física de morango, proveniente de sistemas agrícolas de produção convencional e orgânico, submetido a refrigeração.

Abstract

This experiment was carried out to determine the physical characteristics of ‘Oso Grande” strawberries, fruit conducted in conventional or organic production agricultural systems. The strawberry were conditioned in holed rigid trays of polytereftalate ethylene and stored at 1 or 11ºC and 70% RH. In the experiment the completly randomized design was used, with factorial outline used 2x2 (two production agricultural systems: conventional or organic; and two cold storage temperatures: 1 and 11ºC). Colour (L*, C and hº) and fresh mass loss were evaluated each three days during 15 days. In general, brightness (L*) decreased during storage. Independent the system production (organic system or conventional), the strawberry shower the maximum shelf life of 6 days, when fruit showed fresh mass losses above 10%.
