%X O objetivo desta pesquisa foi caracterizar fisica e qu赤micamente cultivares de cebola CNPH 6400 e 車ptima durante o armazenamento refrigerado. Bolbos foram colhidos, submetidos 角 cura, selecionados e, em seguida armazenados por 60 dias. A cada 10 dias, analisou-se perda de massa fresca, firmeza, cor, s車lidos sol迆veis totais (SST), acidez titul芍vel total (ATT) e pung那ncia. Observou-se, durante o armazenamento, aumento de 3% e 2% para perda de massa fresca, 57% e 50% para brilho, 6% e 22% para redu  o de firmeza, 16% e 12% para SST e 28% e 14% para ATT nas cvs CNPH 6400 e 車ptima, respectivamente. Verificou-se ainda, valores maiores de a* para CNPH 6400 e maiores valores de b* para 車ptima. Ao final do armazenamento, a pung那ncia foi 2 vezes maior na CNPH 6400 em rela  o 角 車ptima. Concluiu-se que as cebolas tiveram altera  es significativas em suas caracter赤sticas, sendo estas dependentes da cultivar e do tempo de armazenamento. The objective of this research was to comapre bulb physical and chemical characteristics of onion cvs. CNPH 6400 and 車ptima during refrigerated storage. Bulbs were collected, subjected to a cure, selected, and then stored for 60 days. Every 10 days, we analyzed weight loss, firmness, color, total soluble solids (SST), total acidity (ATT) and pungency. It was observed during storage, increased 3% and 2% weight loss, 57% and 50% for brightness, 6% and 22% reduction of firmness, 16% and 12% for SST and 28% and 14% for ATT in CNPH 6400 and 車ptima cvs, respectively. Higher a* values were found for cv. CNPH 6400 while cv. 車ptima had higher b* values. At the end of the storage period, the pungency was 2 as often greater in the cv. CNPH 6400 in relation to the cv. 車ptima. It was concluded that the onions suffered significant changes in their physical and chemical characteristics which were dependent on the cultivar analyzed and storage time elapsed.
