Post-Harvest Conservation of Green Maize in Different Packages

Abstract

Maize is the second most produced grain in Brazil, which has the potential to produce green maize, which is maize harvested before physiological maturation. Aimed with this work evaluate three packages for postharvest conservation of green maize at room temperature in the conditions of the Brazilian cerrado. The double hybrid AG-1051 were planted. After the cobs were harvested, they were submitted to three treatments, each treatment with three repetitions and each repetition contained 4 cobs. The analyzes carried out were: fresh weight loss, instrumental coloring, titratable acidity content, ascorbic acid content and soluble solids. The results were submitted to the 5% Tukey test and regression. The treatment with polyethylene stood out for the loss of fresh mass, color of the maize cobs as for the levels of titratable acidity, presenting the best results and, for the same parameters, the maize cobs of the treatment with straw showed the lowest results, showing that the conservation straw cobs is the least suitable treatment. As for the content of ascorbic acid and soluble solids, the results showed no statistical difference for any of the treatments showing that they kept the contents unchanged during storage.
