  • Physiological, sensory and microbiological evaluations were conducted during fermentation of Chungkookjang. with Choi-cha (non-fermented green tea) powder in efforts to improve the sensory quality of Chungkookjang. Growth of fermentative microorganisms in Chungkookjang was inhibited by Choi-cha; the pH and VBN value decreased as the concentration of Choi-cha increased. Brightness (L) and redness (a) of Chungkookjang fermented with Choi-cha were significantly decreased, resulting in the appearance of all samples fermented with Choi-cha being less attractive than was the control. The sensory quality of Chungkookjang was significantly increased when Choi-cha was added up to 3%, (w/v), and off-odor was reduced. The antioxidative property of Chungkookjang fermented with 3% (w/v) Choi-cha was significantly higher than that of the control. This result indicated that the sensory quality of Chungkookjang was improved by fermentation with 3% (w/v) of Choi-cha powder.

  • The value of Korean ginseng has been known in the world since the 4th century B. C. Red ginseng is hot-steamed, and then dried for the purpose of long-term storing. Through the steaming and drying process, its moisture rate is reduced to 14% and its color becomes citrine or light yellowish brown. Its hardened structure enables long-term storage without any deformation. Especially, Korean red ginseng contains substances that promote micro-physiological activities which are not found in American or Sanchi ginseng. Ginseng is produced in diverse forms for the customer's convenience. In this study, these are classified as sliced, dried, and honeyed ginseng, granulated tea, extract, powder, capsules, tablets, drinks and candy. Package design is one of the most effective method in the marketing fields. However, in this research, we found that red ginseng packages are not variously and properly developed in materials and designs. The research pointed out the problems and discuss ways and means of the package design.

  • This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.

  • The purpose of this study was to investigate the effects of different moisture addition and sugar on the quality of Nokcha-julpyun, during 24hrs. As the result of the Hunter's color values, lightness, redness and yellowness were increased slightly or not after 24hrs and showed middle levels in $30%{\sim}40%$ moisture addition groups. It seemed that the addition of sugar to Nokcha-julpyun affected the redness and yellowness of 40% and 45% moisture addition groups more than the other groups. In texture profile, springiness of Nokcha-julpyun was not different significantly among all the groups during storage. Cohesiveness was getting higher by increase of moisture level and getting lower by storage. Sugar addition seemed to lower the rate of decrease of cohesiveness. Chewiness and hardness were getting lower by increase of moisture level and getting higher during storage. In this case sugar addition seemed to interfere the Nokcha-julpyun to be hard. Adhesiveness showed to be decreased during storage, but didn't show any correlations with water level. Sugar addition to Nokcha-julpyun seemed to increase springiness and adhesiveness slightly. 35% moisture and sugar addition group had the lowest values in springiness, hardness and cohesiveness. Both 40% groups and 45% moisture and sugar addition group had high values in springiness, cohesiveness and adhesiveness but had the lowest values in hardness and chewiness. In sensory evaluation, $30%{\sim}40%$ moisture addition groups showed good preferences in color, flavor, taste, tenderness and chewiness, and the 35% moisture and no sugar addition group showed the best overall acceptance among the groups. Above results indicated that moisture addition level with $30%{\sim}35%$ seems to give the best quality to Nokcha-julpyun added green tea powder with 6% level, and for the purpose to reduce the changes of texture profiles during storage, it is benefit to add sugar a little to Nokcha-julpyun.

  • Instead of deodorization appararus of fish oil, an adsorbent such as activated charcoal, activated alumina, silicagel, bamboo charcoal was packed in column alone or mixed with preparative ratio, and then test the effective deodorization with bleaching. In the progress of degumming, the effective method was 18 ml of 2.5% oxalic acid per 100m1 of crude large anchovy oil. The optical condition to deacidified was treating for 30 min at $40^{\circ}C$ with 2.5% sodium hydroride solution. The effective deodorization was added with 3% silicagel under the alone treating adsorbent, and mixed treating was 30% activated alumina and 10% silicagel but added to green tea powder was not effective. The major fatty acid of total lipid were 16:0, 20:5n-3, 18:1n-9, 16:1n-7 and 22:6n-3 after treatment of degumming, deacidfication and deodorizing in the large anchovy oil. The oxidative stability of refined anchovy oil added to $\alpha$-tocopherol was validated 20 days under the control, and 30 days in the case of $\alpha$-tocopherol. The 0.01% $\alpha$-tocopherol was more effective than 0.02% $\alpha$-tocopherol.

  • This study was conducted to investigate the effect of ingestion of rice meal with red pepper(Capsicum annuum) as a seasoning upon the plasma gastrin concentration of normal human subjects in Korea. Thirteen normal human subjects including male and female(mean age: 21 years, range: $20{\sim}24\;years$) were studied. After an overnight(about 15 hrs) fast each subject ingested a test meal and a control meal on different days. The test meal consisted of 250 g toiled rice, 250 ml radish soup containing red pepper(dried powder, 3 g), 50 g vegetables and 200 ml barley tea, corresponding to 7.0 g protein, 9.0 g fat and 82 g carbohydrate and the control meal consisted of the same amount as the test meal except that the radish soup was supplied without red pepper. The venous blood samples were drawn before and after the ingestion of meals at the following times: -30, 0, 15, 30, 45, 60, 90, and 120 min for the measurement of plasma gastrin concentration by means of radioimmunoassay. 1) Plasma gastrin concentration in response to the ingestion of control meal without red pepper increased significantly compared with the concentration in fasting state. 2) The increase of plasma gastrin concentration after the ingestion of test meal(containing red pepper) was significantly higher than that after the control meal. It is inferred from the above mentioned results that the ingestion of red pepper as a seasoning has a stimulatory influence on gastrin release in normal human subjects.

  • As the production of chonma became increased by the farmer's cultivation, developments of the processed food such as tea using chonma have been actively pursued. In the present study, the components of chonma and its beneficial effects on health using SD (Sprague-Dawley) rat model were analyzed. The contents of moisture, protein, ash, fat and fiber in dried-chonma were 11.8, 7.6, 3.2, 0.5, and 3.9%(w/w), respectively. The contents of calcium, sodium, iron, phosphorus, magnesium and potassium were 121, 83, 6.2, 170, 69 and 1,278 mg%. When chow diets containing 0, 0.15, 1.5 or 5.0% chonma powder were fed to SD rats for 4 weeks, no significant differences were observed in the composition of the large-intestinal flora, ${\beta}-glucuronidase$ level of the large-intestinal contents and the weight gains of rats. The level of ${\beta}-glucosidase$ was higher and the serum cholesterol level was lower in 5.0% chonma group compared with control group. The highest sedative effect was shown in 0.15% chonma group.

  • We investigated dietary effects of prickly pear cactus (Opuntina ficus-indica) on plasma lipids, platelet aggregation (PA), hemolysis, plasma TBARS and liver enzymes. Twenty eight volunteer diving women in Jeju island had daily 20 g cactus tea containing 27% prickly pear cactus (PPC) powder for 4 weeks, and data for the study subjects were analyzed, on the basis of diagnostic criteria for blood pressure (BP)(${\geq}$ 140/90 mmHg), plasma cholesterol (${\geq}$ 200 mg/dL) and triglyceride (${\geq}$ 150 mg/dL). The subjects with higher BP had higher plasma total cholesterol (TC) and triglyceride (TG) concentrations than those with normal BP. Those with higher TC also had higher TG. Subjects with normal BP or normal TC had higher initial slope of PA than their higher counterpart in BP and TC. PPC intake decreased plasma TG in those with higher BP. PPC intake significantly decreased the elevated initial slope in groups with normal BP, TC, and TG. Hemolysis after PPC intake decreased significantly in all the subjects and plasma TBARS decreased in the subjects with higher plasma TC and higher TG. Glutamic-oxaloacetic transaminase (GOT) significantly increased and total bilirubin significantly decreased in all the subjects after PPC intake. The present study with diving women showed that beneficial effects of short term intake of prickly pear cactus might differ depending on the subject conditions in term of blood pressure, and plasma lipids. However, long term usage of prickly pear cactus may provide preventive effects of cardiovascular diseases to all the population, presumably by hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids and soluble fiber.
