Egg white mix (EWM) added with different ratios of cream $(10{sim}15%,v/v)$ was fermented with Lactobacillus acidophilus (KCTC 2182) and changes of volatile aroma compounds during fermentation for 21 h were investigated. The amount of volatile aroma compounds between pre-fermented EWM, 15 h-fermented EWM, soft ice cream prepared from fermented EWM, and hard ice cream prepared from soft ice cream was compared. The results were as follows: (1) The amount of ethanol increased gradually until 9 h and increased rapidly to maximum value at 12 h and then decreased rapidly. The amount of acetone at 12 h was slightly higher, but it was not changed markedly during fermentation. Diacetyl was detected at 3 h and increased gradually to maximum value until 15 h and then decreased slightly. The amount of butanol was not changed markedly during fermentation. Acetoin was detected at 3 h and increased rapidly until 15 h and then increased gradually. (2) The amount of acetone, ethanol, diacetyl and butanol of pre-fermented sample, 15 h-fermented sample, soft ice cream and hard ice cream increased in proportion to the amount of cream added to EWM. However, the amount of butanol was relatively constant regardless of added cream ratio. The amount of volatile aroma compounds of soft ice cream was higher than that of other samlples, while that of pre-fermented sample was lower than that of other samples. Diacetyl and acetoin were not detected in pre-fermented sample.
