Abstract
In this study, A method for confirming the putrefaction point of apples by using odor variation as applied in apple storage. The samples were obtained from apple storage at Chuncheon shi Dongnae-myeon using by lung sampler. The complex odor was separated by GC/O and individual odors were then analyzed. In the apple storage, the varieties and number of apples vary based on cultivarsand sales volume of apples. Thus, using an emission chamber in the apple storage is difficult. The odor value of the emission chamber and apple storage is denoted by standardizing the sizes and number of apples. The variations in the ratios of aroma value and off-odor value were investigated. The ratio of the aroma value and off-odor value in the emission chamber increased. However, the apple storage values were applied on the number of apples, thus the values alternately increased and decreased in most cases. If the internal change of apple started, it is ratio of aroma value and off-odor value is cloese to zero. and If the External putrefaction on the apple surface is confirmed, the log value becomes larger than 0.5. Complete putrefaction in the stored apples, the log value close to 1.5. We therefore confirmed that this noninvasive method using odor variation can apply to monitoring the quality of apples in storage.
