  • Headspace solid phase trapping solvent extraction (HS-SPTE) and GC-MS was applied for the characterization of volatile flavors from fennel, anise seed, star-anise, dill seed, fennel bean, and Ricard aperitif liquor. Tenax was used for HS-SPTE adsorption material. Recoveries, precision, linear dynamic ranges, and the limit of detection in the analytical method were validated. There were some similarities and distinct differences between fennel-like samples. The Korean and the Chinese fennels contained trans-anethole, (+)-limonene, anisealdehyde, methyl chavicol as major components. The volatile aroma components from star anise were characterised by rich trans-anethole, (+)-limonene, methyl chavicol, and anisaldehyde. Additionally, principal component analysis (PCA) has been used for characterizing or classifying eight different fennel-like samples according to origin or other features. A quite different pattern of dill seed was found due to the presence of apiol (dill).

  • This study was conducted to investigate the effects of herbs (dill weed, fennel seed and rosemary) on color stability and lipid oxidation of ground pork patties during storage at $2^{\circ}C$ and $-20^{\circ}C$. Lipid oxidation was determined by the thiobarbituric acid reactive substances (TBARS) method. Fennel seed was identified as being the most effective ingredient in terms of meat redness (Hunter a-values) during storage at $2^{\circ}C$ (p<0.05). Patties treated with rosemary had lower Hunter a-values than control, and dill weed was the least beneficial in influencing meat redness, having significantly lower a-values than control patties. During frozen storage at $-20^{\circ}C$, no significant differences in a-values were observed between the control patties and those treated with fennel seed. Patties treated with rosemary had lower a-values than control and patties with dill weed had negative a-values throughout storage. The cooking process increased Hunter L-values and decreased a-values in all patty samples. TBARS values increased during storage. Rosemary displayed excellent antioxidative activity as evidenced by the completely inhibition of TBARS formation of cooked pork patties. Dill weed and fennel seed also exerted an intermediate but significant antioxidant effect during storage (p<0.05).

  • Larvicidal activity of 34 plant essential oils were tested against the 4th instar larvae of Culex pipiens pallens. Among them, six oils (basil, fennel, caraway seed, lime, thyme red, and thyme white) showed more than 80% mortality at 100 mg $litre^{-1}$ concentration. GC and GC-MS analyses of the six essential oils and bioassay of their components revealed that anethole (a major component of fennel and basil oil) and (+)-limonene (a major component of caraway seed and lime oil) showed higher larvicidal activities than others. In addition to the above two components, ${\alpha}$-phellandrene, p-cymene, $\gamma$-terpinene, ${\beta}$-pinene, and thymol showed higher larvicidal activity than Bt product.

  • The principal objective of this study was to assess the effects of the addition of natural plant materials on the color and lipid oxidation of ground pork. Ground pork was blended with 0.3% (w/w) of cactus, fennel seed, orange peel, and rosemary, respectively, and stored for 8 days at $2^{\circ}C$. The pH, meat color, thiobarbituric acid reactive substances (TBARS) values, and metmyoglobin (MetMb) contents were measured. A gradual increase in pH was noted with increases in the storage time. The Hunter a (redness) value decreased until 6 days of storage, and evidenced no noticeable changes there after, and the cactus evidenced significantly higher a values than other groups over time (p<0.05). The TBARS formation was effectively inhibited by the addition of rosemary for 6 days of storage, reflective of strong antioxidative activity (p<0.05). The antioxidative activity on the lipid oxidation of cooked pork patties was noted in the following order: rosemary, fennel seed, cactus, and orange peel. The MetMb contents increased according to storage period, and no significant differences were noted among the meat patties.

  • Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.

  • The use of deodorizing plant products such as persimmon leaves, pine needles and fennel seeds to mask the characteristic odor of kimchi has been proposed. Therefore, in this study, the effect of deodorizing plants on kimchi fermentation and the profile of volatile flavor compounds was investigated. During sensory evaluation tests of sour and fermentation odors of kimchi, plant extract-added kimchi showed higher sensory scores than chopped plant-added kimchi. Additionally, kimchi containing pine needle extracts (0.3-0.6%) and fennel seed extracts (0.05-0.1%) showed higher sensory scores than untreated kimchi. In addition, pine needle extract and fennel seed extract had a significant influence on kimchi fermentation characteristics such as pH, total acidity and the concentration of lactic acid bacteria. The volatile flavor compounds of kimchi and deodorizing plant extracts were also analyzed using GC/MS and the correlation of volatile flavor compounds in kimchi, plant extracts and plant-added kimchi was examined. The results revealed that the sour and fermentation odors of kimchi were reduced using deodorizing plant extracts by changing the kimchi fermentation characteristics.

  • This study was carried out to get basic information about the morphological and production characteristics of fennel populations different origin under different ecological conditions in Hungary. The Korean population can be registered as a medium high genotype and showed a more accelerated growth characters than Hungarian taxon and the two populations have a medium homogeneity $(CV\;=\;4{\sim}22%)$. In the second year plant height in Hungarian taxon was significantly higher than that of the Korean population. The shooting dynamic of individual plants might be heterogeneous in both taxa and the Korean population was not only shorter in the height but had also less shoots by 16% than the Hungarian one. The Hungarian taxon exceeded the umbel size and numbers to the Korean one (by 3.62 cm in the average) and the variability in the populations was high $(CV\;=\;29{\sim}49%)$. Seed size was proved to be also a discriminative feature between the examined taxa. With small deviations (CV < 2) the Hungarian population produced seeds longer by 38%. Homogeneity in the populations was dependent more on the vegetation years and on the characteristics measured but less on the origins, respectively.
