The objective was to review the effects of the drying and storage conditions of corn on the physical-chemical quality in the processing of starch and flour, in the production of animal feed, and in the industrialization of ethanol. Initially, the review presented an overview of the post-harvest stages of corn grains, highlighting drying and storage. The main drying and storage methods used for corn grains were presented. Among the drying conditions, the air temperature was the main factor that affected the properties of starch, flour, feed, and ethanol produced from corn. It was verified that the corn grains submitted to drying at temperatures below 60 °C obtained better results in the industry. In storage, in addition to the storage time, factors such as temperature and moisture content of the grains affected the physical-chemical quality of the processed products. In this stage, the moisture content below 14% and the storage temperature below 25 °C conserved the physical-chemical quality of the grains and obtained better processing results. Further studies are needed to assess the effects of the drying and storage conditions of corn on the properties of flour, starch, animal feed, and, mainly, ethanol production.
目的是回顾玉米干燥和储存条件对淀粉和面粉加工、动物饲料生产以及乙醇工业化过程中物理化学品质的影响。起初，该综述介绍了玉米籽粒收获后的各个阶段，重点强调了干燥和储存。介绍了用于玉米籽粒的主要干燥和储存方法。在干燥条件中，空气温度是影响玉米所产淀粉、面粉、饲料和乙醇特性的主要因素。经证实，在低于60°C的温度下干燥的玉米籽粒在工业上能取得更好的效果。在储存方面，除了储存时间外，籽粒的温度和水分含量等因素也会影响加工产品的物理化学品质。在此阶段，水分含量低于14%且储存温度低于25°C能保持籽粒的物理化学品质，并取得更好的加工效果。需要进一步研究来评估玉米干燥和储存条件对面粉、淀粉、动物饲料，尤其是乙醇生产特性的影响。
