This study was performed to provide basic data on the use of green laver for jook. To accomplish this, we tested water content, color, brightness, mechanical qualities and sensory qualities in comparison to a control group. Higher concentration of green laver powder decreased water content, lightness, redness, viscosity and pH. Further, higher concentration of green laver resulted in lowered preference regarding appearance. However, better flavor was with the result of a higher amount of green laver. Therefore, green laver seems to have benefits for use in oriental soup. Accordingly, we expect there is potential for use of green laver for jook.

This study analyzes the differences to examine which education is more effective for practical cooking skills. A survey was conducted on the 4 year university students majoring in culinary arts to examine the recognition levels of culinary practice education for the purpose of searching for an improvement plan for culinary education. The results are as follows. Seniors recognize the importance of learning theory, while the classes offered now are focusing on getting cooking certificates. The students approach cooking not only for eating food but also for the arts, showing increased interests in 'creative food' and 'fusion food.' In class, they feel the necessity of establishing a standard for a fair assessment and English skills for the globalization of food service. Hereupon this study recognizes the current state of culinary education service, draws factors which decide the quality of culinary arts education, and examines student satisfaction with theoretical education, practical education, assessment, and external education by using a factor analysis of twenty quality attributes. Through the development and application of various programs, operation of open practice classes and culinary organization reflecting social changes in learning courses, the culinary arts education is considered to be more vitalized. In this respect, this study introduces four measures which were designed to facilitate the education of highly-skilled human resources in the culinary field.

This study was to investigate dietary life and eating-out style related to breakfast frequency of male students in culinary college. This survey was conducted using questionnaires for 110 male students at college in Hongseung. Mean height and body weight of those we investigated was 174 cm and 70.5 kg. The one to two times per week breakfast eating group was 34.55%, which is exceedingly numerous; none per week breakfast eating group was 30%; three to tow times per week breakfast eating group was 15.45%; everyday breakfast eating group was only 9.09%. The breakfast frequency was very low, and the not-eating breakfast problem is serious to think of in male college students. Mean weight, body fat and body mass index(BMI) of the everyday breakfast eating group was lower than the other group even it was not significant. The self-boarding house or dormitory living condition group was not eating breakfast was significant. So a correct dietary lift and eating habit should be taught further for male college students. The smoking group was a significant low frequency of breakfast eating, as well as the lower frequency of breakfast, or worse recognition of self health condition. Higher frequency of breakfast showed more contentment of self body weight. Cooked rice was significantly the most preferable for breakfast. The lower breakfast frequency tended to eat breads or cereals. The lower frequency of breakfast, self recognition of eating rate as speedier was significant, and tended to have a higher frequency of eating-out because of being annoyed by cooking. The lower breakfast frequency ate out more. Twenty five percent of the everyday breakfast eating group ate out because of a special day, and thirty five percent of the not eating breakfast group did so because of being annoyed by cooking. Their mean dietary evaluation grade was under the normal grade, which means that culinary college male students' dietary lives were poor. The lower frequency of breakfast and lower grade of food life evaluation, indicates the importance of nutritional breakfasts education should be improved for male culinary college students also.

Culinary mushroom Pleurotus pulmonarius has been popular in Asian countries. In this study, the anti-oxidant, cholinesterase, and inflammation inhibitory activities of methanol extract (ME) of fruiting bodies of P. pulmonarius were evaluted. The 1,1-diphenyl-2-picryl-hydrazy free radical scavenging activity of ME at 2.0 mg/mL was comparable to that of butylated hydroxytoluene, the standard reference. The ME exhibited significantly higher hydroxyl radical scavenging activity than butylated hydroxytoluene. ME showed slightly lower but moderate inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase than galantamine, a standard AChE inhibitor. It also exhibited protective effect against cytotoxicity to PC-12 cells induced by glutamate ($10{\sim}100{\mu}g/mL$), inhibitory effect on nitric oxide (NO) production and inducible nitric oxide synthase protein expression in lipopolysaccharide-stimulated RAW 264.7 macrophages, and carrageenan-induced paw edema in a rat model. High-performance liquid chromatography analysis revealed the ME of P. pulmonarius contained at least 10 phenolic compounds and some of them were identified by the comparison with known standard phenolics. Taken together, our results demonstrate that fruiting bodies of P. pulmonarius possess antioxidant, anti-cholinesterase, and inflammation inhibitory activities.

This purpose of this study is to examine the antioxidant and antimicrobial activities of Persicaria hydropiper L. extract in 70% ethanol and in water, a medicinal herb, as an effort to examine the potential of medicinal herbs for development of antioxidants and natural preservative substitutes. The total poly-phenol content in the 70% ethanol extract and in the water extract were 19.88 mg/g and 7.46 mg/g, respectively. The DPPH radical scavenging activity was 90.99% and 64.98% in the 70% ethanol extract and water extract, in which 70% ethanol extract showed a higher activity. The antioxidant effect of Persicaria hydropiper L. extract appears to be very good and due to its excellent growth inhibitory effect on food-poisoning-causing microorganisms in the food, it is thought to be utilized as a potential natural preservative substitute in many areas.

This study is on different dry methods for Artemisia sp. which were not affected by the dry matter percent. Essential oil components such as 1,8-cineol and terpineol were highly affected by the dry method. 1,8-cineol and terpineol components were decreased by adaptation of the heated oven-drying method and the freeze-drying method. Borneol components were increased through shady sun-drying, sun-drying and freeze-drying. Heated oven drying method decreased the vitamin C content. Vitamin C content was decreased in oven-drying about 50% during this period, but only 10% decreased in the freezing dry method. Qualities were changed by different drying methods. Therefore, different dry methods of Artemisia sp. were applied to the flavorgen.
