This study was conducted to design and manufacture a final prototype of garlic separator and to evaluate its performance. The performance of garlic separation was compared with manual separation. The final prototype for garlic separation consists of bucked-elevator device for automatic feed of garlic, rotating cone typed device, blower, and power transmission device. The optimal condition of outlet clearance was 19 mm and in this clearance, the proportions of fragment garlic separated in the large quality of Namdo garlic and all quality of Uiseong garlic were above 95% and above 85%, respectively. All proportion of damaged garlic was below 5% for all variety and quality. The garlic separation capacities of this developed machine were 310 kg/h for Namdo garlic and 293.6 kg/h for Uiseong garlic in the large quality. Capacities of final prototype compared with human being were $12.9{\sim}19.6$ times for Namdo and $24.2{\sim}31.7$ times Uiseong garlic, respectively.

The essential oils were isolated by steam distillation from 13 spices used for curry. Antimicrobial activity of essential oils for two strains of Gram(+) bacteria, Gram(-) bacteria, lactic acid bacteria, yeast and mold were investigated by agar diffusion method. 5 spice essential oils(clove, cumin, nutmeg, oregano, rosemary) having high antimicrobial activity were selected and their minimal inhibitory concentration(MIC) were measured. Very low concentration ($0.2{\sim}9\;mg/ml$) of 5 spice essential oils were sufficient to prevent microbial growth. The data show that Gram(+) bacteria were more sensitive to the antimicrobial compounds in spices than Gram(-). But though Gram(+) bacteria, lactic acid bacteria were less sensitive to the compounds than Gram(-).

Background: Tobacco smoking is a major cause of preventable disease and death worldwide. Kreteks are clove-flavored cigarettes made from a combination of tobacco and ground-clove mixed with a sauce, smoked widely in Indonesia. Because health and social consequences of kretek smoking are potentially as great as those of traditional cigarettes, this study examines the prevalence of kretek smoking in Indonesia and associated risk factors. Materials and Methods: The study used nationally representative Indonesia Global Adult Tobacco Survey data. Multiple logistic regression analysis was employed to identify correlates of kretek smoking. Results: One-third of Indonesian adults smoked tobacco of which about 90.0% smoked kreteks. Prevalence of kretek smoking among men (60.9%) was more than 25 times the rate among women (2.3%). Overall, the highest prevalence of kretek use was in the age group 45-54 years (36.5%), followed by 34-44 (35.1%), 25-34 (34.2 %), and 55-64 years (32.8%). By wealth index, prevalence of kreteks smoking among those in the middle index was almost 50% above the rate for the wealthiest group (36.4% vs 24.8% respectively). Logistic regression results showed that being male, being older, having less education, and being less wealthy were significant predictors of kretek smoking, while urban vs rural residence was not. Conclusions: Kretek smoking is common in Indonesia and is entrenched in the sociocultural fabric of the country. However, potential consequences of kretek smoking, particularly as risks for noncommunicable diseases, underscore the importance of a comprehensive approach to tobacco control as outlined in the World Health Organization's MPOWER strategies.

This study was investigated on antioxidant activities of water, methanol and ether extracts of clove. The extraction yields of water, methanol and ether extracts were 34.7, 21.4 and 17.0%, respectively. Total phenolic contents of water, methanol and ether extracts were 23.1, 55.7 and 34.9%, respectively. Eugenol contents were 6.1 and 8.1% in methanol and ether extracts, but it was not detected in water extract. Electron donating abilities of water, methanol and ether extract were 36.1, 30.9 and 29.7%, respectively. In linoleic aicd system, the ether extract showed more high antioxidant activity than water and methanol extracts. The antioxidant activity of ether extract was almost equal that of $\alpha$-tocopherol, but weaker than that of BHT In linoleic acid emulsion system, the water extract showed higher or stronger antioxidant activity than methanol and ether extracts. Antioxidant activities in linoleic acid emulsion substrates were in order of BHT ＞water extract＞methanol extract＞ether extract＞ $\alpha$-tocopherol.

This study was conducted to evaluate cultivation to save the production method cost of warm type garlic. The optimum system for producing excellent seed bulbs by using bulbils of garlic has been required. The bigger size bulbils induced fast growth and lower rate of non-cloved bulbs. The ratio of non-cloved bulbs was the highest in the 0.1 g bulbils sowing of 'Namdo' and was low in the big size bulbils sowing. The bulbil growth rate of 'Deaseo' was much faster than that of 'Namdo', but most of 'Deaseo' bulbils showed low rate of non-cloved bulbs and small size scales in bulbs. The higher productivities of "Namdo" bulbils appeared at the September 11th sowing time, but 'Deaseo' bulbils produced small size non-cloved bulbs and got the very low ratio of non-cloved bulb production in all of the treatment, sowing that Jeju Island could not produce the non-cloved bulbs with 'Deaseo' garlic bulbuls. The growth rate such as leave number, leave length, bulb and clove size in the sowing distance of big size bulbils increased as the sowing distance was wider, but the rate of non-cloved bulbils decreased regardless of treatment. More than 3 g clove in the $10{\times}15cm$ distance of bulbs was produced resulted in sowing clove production potentials by using big size bulbil.

The alkali extraction of anticoagulant from a clove revealed 3-to 6-fold more effective than hot-water extraction. The highest anticoagulant activity was found with 0.1 N NaOH at 7$0^{\circ}C$. The anticoagulant fractions from a clove, EC-2B and EC-2C were separated by alkali extraction, ethanol precipitation, cetavlon treatment, and ultrafiltration. The anticoagulant activities of these two fractions were, respectively, 6.57 and 8.63 times higher than those extracted with hot-water. As of the sensory evaluation, boiled pork added with EC-2B fraction revealed similar sensory acceptability to raw clove material, while EC-2C fraction had low sensory acceptability due to a mild chemical odor. Antibacterial characteristics against pathogenic microorganism of both fractions were confirmed in the control strain. The inhibitory effect of growth by EC-2B was noticed above 0.016% in S. aureus. Also, EC-2C showed the inhibitory effect at 0.004% in both E. cole and S. aureus control strains.

Seven kinds (acacia, cochineal, catechu, grape peel, persimmon, gallnut and clove) of color powders obtained from natural resources and their mixtures were evaluated for their biological activities, such as antioxidant (ABTS and DPPH radicals scavenging), cholesterol absorption, and COX-2 inhibitory activities. Catechu, gallnut and clove were selected for the further studies due to its the best activities. The cholesterol absorption, COX-2 inhibitory, ${\alpha}$-amylase inhibitory and ${\alpha}$-glucosidase inhibitory activities were measured using the mixtures of catechu, gallnut and clove. The ABTS radical scavenging activity of the seven types of natural color powders were higher than the DPPH radical scavenging activity. The cholesterol absorption activity was significantly higher in cloves. The COX-2 inhibitory activity was significantly lower in acacia. The ${\alpha}$-amylase inhibitory activity was higher in catechu and gallnut, indicating that there were no significant difference between two mixtures. The ${\alpha}$-glucosidase inhibitory activity was the highest in catechu, which was higher than that of the catechu-containing mixtures. From all these results, a synergistic effect could be obtained when utilizing a mixture of powders rather than using only individual type. Since the activity of each powder was different, further studies will be required for clarifying the interactions between mixtures.

Edible flowers are harvested at the full bloom stage and distributed without floral stems, which makes the flower quality deteriorated quickly. Thereby, this study was carried out for selection of effective storage film at room temperature during the distribution of edible flowers. Edible flowers, snapdragon (Antirrhinum majus), pot-marigold (Calendula officinalis), sweet violet (Viola odorata), clove pink (Dianthus caryophyllus), wild pansy (Viola tricolor), nasturtium (Tropaeolum majus) were used to select the effective storage film at room temperature during the distribution, polyethylene (PE) film (0.03 mm), polypropylene (PP) film (0.03 mm). PP (LF10) film packing was very effective for longer shelf life for sweet violet, clove pink, and wild pansy. But, there were little different for pot-marigold and nasturtium. Wilting at sweet violet, clove pink, and wild pansy, and petal-soft rot and color break at nasturtium were appeared. Browning and rot were appeared to snapdragon.
