Abstract

The aim of this study was to quantify and identify the main causes of butia fruits deterioration and to characterize physical and chemically composition changes during their storage at 5, 15 and 20 °C for 0, 7, 21 and 28 days. After a storage week 47 %, 24 %and 22 % of fruits (by weight) did not show visible defects at 5, 15 and 20 °C, respectively. After 21 days, all the fruits were rotted and stained when stored at temperatures of 15 and 20 °C. The higher temperature and storage time increased the pulp color tone of the fruits (76,7 to 80,5 ° hue). The effects of skin temperature or time storage were null both on dry matter (DM, 21,1%) or trans-β-carotene (1,96 mg/100 g fresh) fruit contents. The trans-β-carotene/100 g content in pulp increased from 1,06 to 1,15 mg. Soluble solids (STT) and titratable acidity of juice decreased during storage time from 14,8 to 10,1 °Brix and 1,60 to 1,37 (% citric acid), respectively. Under study conditions it is concluded that 47 % of butia fruits remained without defects for consumption in natura or processed when stored for 7 days at 5 ºC.
