Summary

In order to know the performance of the packaging material in storage and its effect on the preservation of the germinative power of the seed, five packaging materials for Coffea arabica seeds, stored for 12 months in a cold room under controlled environment conditions, at 10,5 ° C and 65% of relative humidity, on average, were evaluated. The packaging materials evaluated were: 6 gauge polyethylene, Kraft paper, trilaminated (PE, aluminum and paper), fique and bilaminated polyethylene (multilayer PE). Coffee harvested at the Naranjal Experimental Station and processed at the Cenicafé seed processing unit was used. The dry parchment coffee with 11% humidity was packed and placed randomly inside the cold room at Cenicafé. Monthly samplings were taken to measure the moisture content and carry out germination laboratory tests that allowed evaluating the effect of the packaging material on the germination percentage. The statistical analysis of the results allowed to conclude that the packaging materials with the highest barrier to water vapor, oxygen and carbon dioxide (polyethylene, trilaminate and bilaminate polyethylene) preserved the quality of the seed during the twelve months, maintaining the percentage of germination above 94%, on average. In turn, the packages that offered a lower barrier (Kraft paper and fique) affected the germination of the seed to a greater degree, with significant decreases from the sixth month, placing it between 87% and 88%, on average, but with minimum values of 75% and 76%. Initial germination was 96% with a standard error of 0.9428%. Under the conditions studied, the Kraft paper bag, which is currently used for packing the seed, is considered a suitable material for storage for periods of less than six months.
