Changes in Aroma Pattern of Campbell Grapes by Treatment of Phytoncide Pads Derived from Pine Bark Using GC-MSD Electronic Nose

초록

In order to find out the effects of shelf-life extending, Campbell grapes were treated with phytoncide pads and compared it with control and other treatments like sulfur dioxide acid pads. With using the phytoncide pad derived from pine tree extract, the pattern of fragrance components according to the storage period of Campbell grape was analyzed by GC-MSD electronic nose. The proper selection of qualitative sensors (peaks) used in the multi-variate chemical analysis of electronic noses distinguished the pattern of fragrance components of electronic noses over the storage period of grapes. In addition, the results of PCA and DFA analysis showed that the GC-MSD electronic nose can distinguish the difference according to the storage period. The ethanol from GC-MSD increased until 6 days of storage and then decreased from 9 days of storage, and by treatment, phytoncide pad 2 treatment showed a pattern of fragrance components with extended shelf life.
