The objective of this study was to evaluate the organoleptic profiles of Kefir and yogurt supplemented with Mentha piperita's (peppermint) oil. The organoleptic profiles of Kefir and yogurt were evaluated by 15 trained panelists between 20 to 50 years of age. The products of Kefir and yogurt were prepared with Mentha piperita's oil at concentrations of 0%, 0.1%, 0.3%, 0.5%, and 1.0%. Taste, color, and overall acceptability scores were the same or lower in Kefir supplemented with 0.1%, 0.3%, 0.5%, or 1.0% Mentha piperita's oil than the control group (0%). The scores of all categories were higher for yogurt containing 0.1% Mentha piperita's oil than the control group. Taste, color, and overall acceptability decreased in proportion to the added amount of Mentha piperita's oil. Further studies are needed to evaluate the functionalities and effectiveness of Mentha piperita's oil in promoting human health.

Repellencies of herb plants and essential oils against alate Myzus persicae were investigated in a insect cage, a screen house, and a tobacco field. Numbers of nymphs deposited by alate or apterous Myzur persicae were lower on rosemary(Rosmarinus officinalis), silver thyme (Thymus vulgaris), and lemon balm(Melissa of fcianazis). Rosemary and silver thyme show little repellency against alate Myzus persicae on a nearby tobacco plant Rosemary oil, peppermint (Mentha piperita) oil, and ginger oil showed repellency against alate Myzus persicae, but spearmint (Mentha spicata) oil and lavender oil showed little repellency in a screen house. Rosemary oil, ginger oil, peppermint oil, lavender oil, and spearmint oil showed repellency against alate Myzus persicae in a tobacco field, but there was no significant difference among oils.

To investigate the characteristics of immobilized peppermint (Mentha piperita) cells, dry cell weight (DCW), change of cell viability, and oil productivity of the immobilized cells were determined. Peppermint cells were immobilized in polyurethane (PU) foams of $5{\times}5{\times}5$ mm and cultured in a shaking flask. The maximum DCW was 2.1 mg per foam piece after 20 days of cultivation and the cell density was approximately 420 mg per flask containing 200 foams in 200 ml medium. For the first five days of cultivation, the cell viability was about 80$%$ and decreased to 70$%$ during 5 to 20 days of cultivation. The maximum oil productivity, 148 mg/l was achieved after 40 days of cultivation. The immobilized cells were also cultivated in a bioreactor, equipped with a round spiral type impeller, containing 2, 400 PU foams. The cell viability after 30 days of cultivation with chitosan as an elicitor in the bioreactor was 67$%$ and DCW was 2.0 mg per foam piece. Though the cell viability was relatively high in the bioreactor system, the oil productivity was relatively lower than that of the flask system.

Purpose: This study was performed to evaluate the effects of sannamul or herb extract addition to a soybean oil-in-water emulsion during photooxidation in the presence of chlorophyll. Methods: The emulsion mainly consisted of purified soybean oil and citric acid buffer (pH 4.0) at a weight ratio of 4 to 6, with chlorophyll a addition at 6 mg/kg. Ethanol extract of daraesoon, samnamul, basil, or peppermint was selectively added to the emulsion at 400 mg/kg, and emulsions in glass serum bottles were oxidized at $5^{\circ}C$ under 2,600 lux light for 48 hours. Lipid oxidation of the emulsions was evaluated based on determination of headspace oxygen content, peroxide value, and p-anisidine value. Pigments and antioxidants were also monitored. Results: The emulsion with added samnamul extract with high contents of polyphenols and low chlorophyll content showed lower oxygen consumption, peroxide values, and p-anisidine values, whereas basil and peppermint extracts with high chlorophyll contents increased photooxidation. Chlorophylls were degraded during photooxidation of the emulsions, and the degradation rate was highest in the emulsion with added samnamul extract. Conclusion: The high antioxidant activity of samnamul extract in the photooxidation of soybean oil-in-water emulsion could be due to low chlorophyll content, high concentrations of polyphenol compounds in the extract, as well as rapid degradation of chlorophylls during oxidation.

To investigate the effects of cultivation on the aroma characteristics of essential oil of peppermint (Mentha piperita L.), experimental peppermints were cultivated with different treatments of field mulching, soil fertilization, and harvesting time. Aroma characteristics of the different mint oils were analyzed by gas chromatography (GC) and GC/mass spectrometry (MS)/infrared spectroscopy (IR). Growth of peppermint with vinyl muching was faster in the early stage of cultivation, but became almost same in the harvest date. The higher amounts of rainfall and sunshine hour resulted in the better growth of stem and leaf of the peppermint. Contents of menthone in the essential oils from the peppermint cultivated in 1990 increased as harvest date delayed from late June 25 to late July 26 the same period. In 1991 menthone decreased from June 25 to August 5, but l-menthol increased from June 25 to august 5. The results indicated that the sunshing hour affected biosynthesis of the components. Contents of menthofuran increased significantly from early June to late July. The optimum cutting date resulting best oil production was late July 7 in 1991.

Objective: In this study, we tried to investigate the antimicrobial activity of natural herbaceous plant-derived essential oils against oral disease-causing bacterial strains and establish the scientific evidences to apply them to the dentifrice, mouthwash, and other uses. Methods: We used the disk diffusion method with 23 types of 100% natural essential oils to verify the antimicrobial effect against Streptococcus mutans, Porphyromonas gingivalis, and Lactobacillus rhamnosus. After adhering to the surface of the plate culture medium, $20{\mu}l$ of the essential oil was prepared, and the diameter of the transparent ring was measured after incubation for 24 hours. All the experiments were repeated three times. Results: Among 23 types of oils, 13 were effective against all three strains: myrrh, ginger, basil, carrot seed, tea tree, patchouli, ylang ylang, cypress, lemongrass, cinnamon, peppermint, lavender, and eucalryptus. Seventeen oils were effective against S. mutans, and myrrh, basil, and carrot seed showed high antimicrobial activity. Eighteen oils were effective against P. gingivalis, and tea tree, carrot seed, and cinnamons showed high antimicrobial activity. Sixteen oils were effective against L. rhamnosus, and carrot seed and peppermint cinnamon showed high antimicrobial activity. Conclusion: Consequently, 13 essential oils showed the antimicrobial activity against three bacterial strains, which indicates these essential oils might be used as the effective materials to suppress the growth of oral-disease inducing microorganisms. Moreover, essential oils that have been analyzed activities in this study will be mixed up within the constant range and analyzed their antimicrobial effects to examine the synergistic activity among them.
