This work had the aim of evaluating the effect of three temperatures (5ºC, 8ºC and 11ºC) on the quality of fresh-cut corn on the cob (Zea maiz L.) with normal endosperm, for 8 days, with analyses taken every two days. Corn on the cob of two hybrids was used, a commercial common type from Sementes Agroceres (Ag 1051) and the other from the breeding program Embrapa Milho e Sorgo (Embrapa HT1). The temperature of 5ºC was more efficient to preserve the quality of normal corn by promoting reduced mass loss and higher contents of soluble solids, fructose and glucose. The hybrid Ag 1051 presented lower mass loss, higher contents of moisture and higher content of fructose. The hybrid Embrapa HT1 presented higher initial and final values for soluble solids and higher b* value. The L* value also decreased along storage, indicating browning of the corns along the storage.
