Minimilhos obtidos das cultivares de milho Vivi, híbrido simples de endosperma doce em fase experimental, e AG 1051, híbrido duplo comercial, comum, foram revestidos com cobertura comestível de fécula de mandioca a 2 e 4% e armazenados a 5 ºC. Um tratamento controle, sem revestimento, foi utilizado nas mesmas condições. Foram realizadas análises físico-químicas a cada três dias, durante nove dias, e de perda de massa, diariamente, a partir do terceiro até o décimo segundo dia. Observou-se variação na acidez, no pH e nos teores de Sólidos Solúveis Totais (SST) das amostras ao longo do período de armazenamento. A cobertura com fécula de mandioca não influenciou na acidez e no pH do minimilho obtido da cultivar de milho Vivi, no final do armazenamento, porém elevou a acidez da cultivar AG 1051. De um modo geral, o revestimento com cobertura de fécula de mandioca foi eficiente na preservação da massa de minimilho, no armazenamento refrigerado a 5 ºC. O desempenho da cultivar experimental Vivi foi similar ao da cultivar comercial AG 1051 para as variáveis perda de massa (controle e cobertura a 4%) e acidez (cobertura a 2 e 4%) e melhor para a variável SST (cobertura a 2 e 4%)

Baby-corns were obtained from maize cultivars Vivi, simple hybrid of sweet endosperm in experimental phase and AG 1051commercial double hybrid, common, were coated with cassava starch edible coverage, at 2 and 4%, and stored at 5 ºC. A control treatment, without coating, was used under the same conditions. Physicochemical analyses were conducted every three days for nine days; and daily analyses of mass loss were conducted from the third to the twelfth day. It was observed a variation in acidity, in pH, and in the total soluble solids contents of the samples during storage. There was no influence by the cassava starch coverage on the acidity and on the pH of the baby-corns obtained from cultivar Vivi at the end of storage; however, the acidity of cultivar AG 1051 increased. In general, it can be said that the coating process using cassava starch was effective in preserving the mass loss of baby-corn in cold storage of 5 ºC. The performance of the experimental cultivar Vivi was similar to that of the commercial cultivar AG1051 for parameters such as mass loss (control and coverage at 4%) and acidity (coverage at 2 and 4%). On the other hand, it was better for SST parameter (coverage at 2 and 4%)
