Moisture content and temperature on the preservation of coffee seeds

The aim of this work was to verify the influences of the moisture content and storage temperature in the preservation of Coffea arabica L. seeds. Seeds with 51%, 41%, 34%, 23%, 16% and 10% moisture content were packed in polyethylene bags and stored at temperatures of 30 °C, 20 °C and 10 °C for forty-eight weeks, and submitted to periodic evaluations of moisture content, germination, vigour and sanity. Decreases in moisture content until 10% and temperature until 10 °C were favorable to the maintenance of seed physiological quality. Seed moisture content around 23% favor the establishment of Penicillium sp. and Aspergillus sp.
