BRUNINI, Maria Amalia; OLIVEIRA, Antonio Luis de; SALANDINI, Cleyton Alberto Ramos  and  BAZZO, Flavio Rodrigo. Packaging and temperature influences on the storage of jaboticaba (Myrciaria jabuticaba (Vell) Berg) fruits cv.'SABARÁ'. Ciênc. Tecnol. Aliment. [online]. 2004, vol.24, n.3, pp.378-383. ISSN 0101-2061.

Were evaluated mature jaboticaba 'sabará' fruits packaged into polystyrene expanded trays covered with stretching and sticking PVC plastic film, with stretching thickness of 12 and 20µm, and packaged into tereftalato polyethylene trays covered with stretching and sticking PVC plastic film, with thickness of 12 and 20µm. Into each tray were placed 25 fruits. The trays were stored at 11±1ºC with 98%UR and at environmental conditions (23,6ºC to 28,3ºC with 53,7% to 68,3%UR). Jaboticaba fruits packaged into tereftalato polyethylene trays (12x20x5cm) and not corvered with plastic film were used as controls. Taking into considerations the results obtained it is observed that of the use of packaging reduced the weight loss, prolonged the postharvest life of fruits with maintenance the appearance until 6 days,; didn´t interfere, significantly, in the titrable acidity, total soluble solids and pH, but influenced the soluble carbohydrates and vitamin C content. The fruits packed and not recovered with plastic films stored at environmental conditions, resisted until 2 days, but at the end of storage their aspect was not appropriate for market purpose, because showed shrinvelling skin and wither. The refrigeration condition improving the firmness of packaged fruits not covered with plastic film, however after 4 days showed bad appearance, with shrinvelling skin.
