  • 본 연구는 소금과 새우젓 함량을 달리하여 제조한 달걀찜의 수분, 색도, pH, texture 분석 및 관능평가(특성차이검사와 기호도 검사)를 통한 품질특성을 조사하였다. 연구 결과 달걀찜의 수분 함량은 새우젓 함량이 증가함에 따라 감소한 반면 pH는 새우젓 첨가가 증가함에 따라 함께 증가하였다. 색도에서 L값과 b값은 새우젓 함량이 증가함에 따라 둘다 감소하였다. Texture에서는 경도, 씹힘성, 검성의 항목에서 새우젓 함량이 증가함에 따라 감소하는 결과를 보였다. 관능평가의 특성차이 검사 결과 외관(노란색, 보드라운 느낌)은 새우젓 함량이 증가할수록 낮게 나타났다. 달걀비린 냄새를 제외한 대부분의 향미특성(구운 견과류 냄새, 비린 냄새, 구운 견과류 맛, 짠맛, 비린 맛, 감칠맛)에서는 새우젓 함량이 증가함에 따라 결과도 증가하는 것을 알 수 있었다. 기호도 평가 결과에서는 소금과 새우젓 함량이 동일한 비율로 첨가된 달걀찜에서 가장 높은 기호도를 보였다. 따라서 소금과 새우젓의 비율을 1:1로 맞추는 것이 바람직할 것으로 사료된다. 연구의 결과는 향후 달걀찜 제조 및 달걀 관련 요리 연구에 도움을 줄 것으로 기대된다.

  • This study was based on the information provided by 1,180 elementary school children (630 boys and 550 girls) of 5th or 6th grade in Changwon and Gimhae of Gyeongnam province. They were asked about perception and preference for rice foods by questionnaires. The purpose of this survey was to find the way of encouraging rice intake and preference which is currently getting lower because of increasing simple westernized eating habits, and to provide basic information needed for inheriting and improving our traditional rice-based dietary culture. The results are summarized as follows. Most of subjects (91.2%) thought that steamed rice is better than bread for own health. The reason why they chose to eat steamed rice was 'because it is good for health' (61.2%), and 'because it is staple food item that we eat everyday' (26.4%). Seventy one percent of girls and 52.7% of boys gave the answer 'because it is good for health' as the reason for eating steamed rice. The reasons for the importance of the rice-based dietary culture were 'because of its superior nutritional value' (40.8%), and 'because it is our traditional eating culture' (28.6%). While significantly more girls (42.9%) answered as 'because of its superior nutritional value', more boys (39.0%) answered as 'because it is our traditional dietary culture'. More boys (59.0%) preferred noodles than girls' (54.7%), and fruits were preferred more by girls than boys as substitution foods for steamed rice showing significant difference (p<0.01). They wanted rice product developed in the forms such as Ssalamyun (29.8%), Ssalmandoo (24.1%), rice noodles (20.6%), and rice bread (15.6%). The preference score on rice products of subjects was one dish meals (4.27) and drinks (4.26), snacks (3.72), convenience foods (3.61), and steamed rice (3.44) in order. Preferred food showing points over 4 were Ssalbap (plain steamed rice) (4.29) in steamed rice type food, Kimchi bokeumbap (4.56), Bokeumbap (4.55), Bibimbop (4.45), Omelet rice (4.44), Kimbap (4.42), Ddukkuk (4.33), Curried rice (4.33), Jajangbap (4.28), and Ddukmandookuk (4.24) in one dish meal type food, Samgak Kimbap (4.26) in convenience type food, Songpyun (4.48), Injulmi (4.18), Teokbokki (4.71), Ddukkochiguyi (4.46), and rice cookies (4.24) in snack type food, and Shikhye (4.61) and Misugaru (4.28) in drink type food. Based on these results, it may be said that elementary school children think the rice-based diet is good for health and this dietary culture should be inherited and developed not only in a traditional aspect but also in a nutritional aspect. Therefore, more studies are needed to develop various forms of rice food products and cooking recipes.

  • Use of chemical preservative for controlling harmful microorganisms in food products has been debated due to public concerns about food quality because of perceived toxic and carcinogenic potential. Thus, use of non toxic natural antimicrobial agents has become essential. This study was investigated to determine the antimicrobial activity of water or ethanol extract of commercially available tea, and of solvent fractionated ethanol extracts obtained from steamed green tea. Both of water and ethanol extracts of green tea(steamed or roasted), oolong tea and black tea exhibited strong antimicrobial activity against gram positive and negative bacteria, but not effective against yeast and mold. Also, antimicrobial activity of ethanol extract of 4 different kinds of tea was stronger than that of water extract. Among 4 different tea, ethanol extract of steamed green tea was further fractionated. One thousand g/disk buthanol extract had the strongest antimicrobial activity against bacteria and mold. The concentration of the antimicrobial activity of buthanol extract in tested microorganisms ranged from 125~1000 g/disk except for Rhizopus javanicus. Antimicrobial activity of buthanol extract of steamed green tea was not destroyed by heating at 100oC for 60 min and at 121oC for 15 min, which is very stable over heat treatment. The inhibitory effect of the buthanol extract on the growth of Listeria monocytogenes and Staphylococcus aureus was investigated. Growth of both strains was started in the presence of 250 and 500 g/ml after 12 and 24 hour respectively, whereas complete inactivation of both strains was occurred in the presence of 1000 g/ml.

  • Objectives : The purpose of this study was to investigate the anti-inflammatory effects of the aqueous extract of the steamed radix of Rehmanniae glutinosa (SRG) on periodontitis in ligature-induced rat model. Methods: To induce the periodontitis, ligature was placed around the lower first molar in rats. Rats were divided into 4 groups (n = 7), NL (non-ligatured and vehicle-treated), L (ligatured and vehicle-treated), SRG1 (ligatured and 1 mg/kg SRG-treated) and SRG100 (ligatured and 100 mg/kg SRG-treated). Vehicle or SRG solution was applied daily for 14 days and then all experimental rats were sacrificed. To examine the effect of SRG solution on periodontitis, the level of alveolar bone loss, cementum regeneration, gingival tissue degradation, and osteoclast cell numbers were analyzed. Results: Alveolar bone loss was inhibited in ligature-induced periodontitis rats treated with SRG treatment. Histopathological cementum was recovered in SRG1 and SRG100 groups. SRG extract inhibited gingival tissue degradation induced by ligature. In addition, the numbers of osteoclast cells were decreased by treatment SRG in periodontitis rats. Conclusion: Taken together, these results suggest that SRG have inhibitory effects against periodontitis. Therefore, the steamed radix of Rehmanniae glutinosa has may be a potential alternative for periodontitis.

  • Objectives : The objective of this study is to determine the best numbers of steaming-drying cycles of Gastrodiae Rhizoma for both efficacy and taste. We investigated various characteristics among Gastrodiae Rhizoma samples (GSD1, GSD3, GSD5 and GSD7) through the number of steaming-drying cycles increased. Methods : Gastrodiae Rhizoma were steamed and dried at different repeated numbers. They were divided into samples (GSD1; steamed and dried once, GSD3; steamed and dried three times, GSD5; steamed and dried five times, GSD7; steamed and dried seven times) for experiment. They were extracted using water, freeze dried and powdered to analyze proximate composition, free sugar amount, functional components, antioxidant activity and sensory evaluation. Results : Proximate composition and the amount of free sugars of Gastrodiae Rhizoma did not have meaningful differences among samples. Phenolic and flavonoid content of samples were increased by increasing steaming-drying numbers. Gastrodin content had different values and GSD7 was the highest in comparison with others. Increasing steaming-drying numbers led to a increasing in radical and nitrate scavenging activity in samples. Regarding to sensory evaluation, GSD5 was selected as the best sample according to its highest hedonic score mean (5.54/7) among all samples for appearance, color, taste and overall acceptability. Conclusions : The results indicated that 5th-cycling sample was effective in views of functional components, antioxidant activity and sensory characteristics. Moreover, it was suggested that steaming-drying process improved remarkably the effects of Gastrodiae Rhizoma.

  • This study was designed to determine and compare the cognitive enhancing effect of various Codonopsis lanceolata extracts by steaming, fermentation and high hydrostatic pressure process. We prepared water extract of C. lanceolata, steamed C. lanceolata, steamed and fermented C. lanceolata and C.lanceolata by high hydrostatic pressure process and fermentation. Cognitive enhancing effect of extracts was evaluated in scopolamine-induced memory impairment mice using by passive avoidance test and Morris water maze tests. MTT assay was conducted to investigate neuroprotective effect on glutamate induced cell death in HT22 cells. Steamed and fermented C. lanceolata water extract decreased escape latency in Morris water maze test and increased the latency time of the passive avoidance test compared to other extracts. Furthermore, the steamed and fermented C. lanceolata water extract showed neuroprotective effect. These results suggest that steaming and fermentation process more improve cognitive enhancing effect of C. lanceolata than other process.
