In this study, development of the pine needle flavor oils and their application to foods, especially to traditional Korean foods, were investigated. The pine needle flavor oils were prepared by the autoclaving method, and their volatile flavor components(VFCs) were determined by capillary gas chromatographic method The major flavor components of the pine noddle flavor oil were a -pinene 31.1%, pentane 9.8%, tricyclene 7.5%, camphene 6.8%, hexanal 6.2%, propane 6.0%, ${\beta}$-pinene 5.6%, limonene 3.9%. The acceptability of the pine needle flavor oils, sensory evaluation including a preference test and quantitative descriptive analysis(QDA), of the pine needle flavor oil, a sesame oil, and a blended oil (pine needle flavor oil : sesame oil 50 : 50 v/v) was carried out. The blended oil and sesame oil showed much higher preference scores than the pine needle flavor oil, and blended oil was almost as acceptable as sesame oil(P ＜ 0.05). The results seem to indicate that blended oil can be used as a unique substitution for sesame oil in some foods, especially in some traditional Koran food.

Quality characteristics of sausage with added pine needle powder (0%, 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%) as an ingredient. The basic ingredients of sausage consisted of pork meat 60%, olive oil 20%, and ice water 20%. Sensory properties of sausage were analyzed by a sensory test, and the texture and color characteristics were measured using a texturometer and color meter, respectively. In the results of the sensory test, taste, texture, and overall preference were highest in the sample with added 1.5% pine needle powder. The sausage with added 1.5% pine needle powder was moderate in color intensity, pine needle flavor, and astringent taste. Hardness and gumminess of sausage were higher in 1.0% and 1.5% pine needle powder. However, springness and chewiness of sausage showed no significant differences. In terms of color intensity of sausage, L-value and a-value were lower and b-value was higher, depending on the pine needle powder amount. Development of off-flavor of sausage during storage was greater in 0% and 1.5% added sausages than in 2.0% sausage with increasing storage time. As a conclusion, sausages with added 1.5% and 2.0% pine needle powder were the most suitable for making functional sausage with added pine needle powder.

This study was conducted to evaluate whether pine needle extracts can be used as tobacco flavors. Yield of essential oil, absolute and oleoresin extracted from pine needles is 0.07%, 1.20% and 6.08% respectively. The volatile compounds isolated from the three types of extracts were analyzed by gas chromatography(GC) and mass selective detector(MSD). Total 72 components were identified in the three type of extracts including 26 hydrocarbons, 16 alcohols, 13 esters, 9 acids, 4 phenols, 2 aldehydes and 2 ketones compounds. The major components were $\beta$-pinene, $\beta$-caryophyllene, $\delta$-cadinene and 4,5-dimethyl-1,3 -dioxol-2-one. There were 49 volatile components in the absolute, 44 components in the essential oil and 26 components in the oleoresin. The content of hydrocarbons and alcohols was higher in the essential oil extracted by simultaneous distillation extraction(SDE) than in others, while that of esters and acids was higher in the absolute than in others. Especially, phenols and ketones were identified only in the oleoresin. The components such as $\beta$-pinene, bornyl acetate, $\alpha$-terpineol and oxygenated terpenes have characteristic piney and fresh green odor. The contents of these components was higher in the essential oil and the absolute than in the oleoresin. Therefor, the essential oil and the absolute are expected to be more useful than the oleoresin as tobacco flavor.
