  • The purpose of this study is to evaluate quality characteristics of the Cheonggukjang produced using rice straw-derived Bacillus cereus free starter culture (RiBS1). The Cheonggukjang was prepared in 0.1 and 1.0% inoculum concentrations of starter culture and fermented from 12 hr to 72 hr at 40 and $50^{\circ}C$. Amino-nitrogen contents after 48 hr fermentation were 559.6~590.2 mg% and 393.8~494.0 mg% at 40 and $50^{\circ}C$, respectively. Sensory evaluation showed that the Cheonggukjang fermented using RiBS1 starter for 48 hr at $50^{\circ}C$ was better than the control. And we inspected on B. cereus and biogenic amine in the Cheonggukjang produced using RiBS1 starter. As a results, B. cereus was not detected and histamine and tyramine of biogenic amine were $5.53{\pm}0.13{\sim}39.96{\pm}0.62mg/kg$. This research results showed that rice straw-derived B. cereus free starter culture (RiBS1) will be produce the Cheonggukjang with good flavour and taste.

  • The purpose of this study was to evaluate satisfaction degree on menu served and identify food preference of the meal served to 271 business and industry foodservice workers from 4 institutions by gender difference. The demographics indicated that male(54.6%) and female(45.4%) were about an half each, mean age was ranged from 20 to 39 years old. The workers were not contented with most of menu quality attributes served from past foodservice operation. Primary complaint was improper temperature of the meal. Most workers liked meat and fish(52.1%) the most. Sensory quality evaluation from all workers was 3.37 points out of 5 points. However, female workers rated higher on the most of menu(3.72 points) compared with that of male workers(3.35 points), indicating that satisfaction was higher in the female workers(p<0.05). Mean preference of all the menu according to food type also have shown higher in female(3.52 point) than in male(3.45 point). Best food preference according to food type considering cooking method of male was given to barley rice, boiled rice with assorted mixtures, marine product stew, and Kimchi stew. On the other hand, females cared for curried rice, hash rice, and spaghetti but males have shown low preferences to those foods females liked. Also, females liked more of fried, grilled and broiled food. However, both males and females showed indifferent taste about the food cooked with steamed and stewed. From the findings, the business and industry foodservice workers were not well satisfied with menu quality considerably and differed in food preferences by gender clearly. Therefore, the manager of foodservice institution require to consider composition of gender ratio in menu preparation along with sensory quality evaluation to lead the successful foodservice management.

  • 본 연구에서는 백미, 현미, 가바현미, 귀리 및 보리를 이용하여 누룽지를 제조하고 각 곡류 별 누룽지의 품질특성, 아크릴아마이드 생성 정도 및 항산화 활성을 측정하였다. 백미로 제조한 누룽지의 수분 함량은 1.48%로 가장 낮았고, 보리로 제조한 누룽지의 수분 함량은 6.53%로 가장 높게 나타났다. 조단백질, 조지방 및 회분 함량은 곡류의 종류에 따라 다르게 나타났으며 귀리 누룽지는 조단백질 및 조지방 함량이 높은 것으로 나타났다. 가용성 고형분은 보리 누룽지가 1.90°Brix로 가장 높았고, 현미 누룽지는 1.50°Brix로 가장 낮았다. 명도(L*)는 백미 누룽지에서 가장 높았고, 가바현미 누룽지에서 가장 낮았다. 적색도(a*)는 백미 누룽지에서 다른 곡류들에 비해 비교적 높았고, 백미 이외의 다른 곡류에서는 통계적인 차이는 없는 것으로 나타났다. 아크릴아마이드는 백미 누룽지에서 37.24 ㎍/g로 가장 적게 검출되었고, 현미, 보리 및 가바현미로 제조한 누룽지에서는 70.41-99.99 ㎍/g, 귀리로 제조한 누룽지는 255.50 ㎍/g로 가장 많이 검출되었다. 총 폴리페놀 및 총 플라보노이드 함량은 백미 누룽지에서 가장 낮았고, 귀리와 가바현미 누룽지에서 비교적 높았다. 백미를 제외한 곡류(귀리, 가바현미, 현미, 보리)로 제조한 누룽지의 항산화 활성이 백미 누룽지에 비해 높은 값을 보였다. 이상의 결과를 통해, 백미 누룽지에 비해 현미, 가바현미, 귀리 및 보리로 제조한 누룽지의 총 폴리페놀, 총 플라보노이드 및 항산화 활성이 높은 것을 확인하였고, 누룽지 제조를 위한 곡물은 항산화 활성 및 아크릴아마이드 형성량에 대한 종합적인 고려를 통한 적절한 선택이 필요할 것으로 판단된다.

  • In this study, purified cellulose was prepared from rice husk which is one of the major agricultural residues in Korea. The various bleaching processes such as ozone bleaching, $ClO_2$ bleaching and $H_2O_2$ bleaching were applied to remove residual lignin and impurities. In order to increase the contents of ${\alpha}$-cellulose contents, the effects of acid and alkali treatments were evaluated. Although the multi stages of the bleaching processes resulted in less than 0.5 % residual lignin contents, the application of ozone leaded to the decrease in DP(degree in Polymerization) and ${\alpha}$-cellulose contents. The alkali treatment after bleaching processes resulted in pure cellulose which showed more than 98% of ${\alpha}$-cellulose contents.

  • Antimicrobial activities of the Acidic Liquid originated from Carbonized Rice Hull(ALCRH) and the paper treated with ALCRH were investigated to apply ALCRH to functional paper products as a natural antimicrobial agent. ALCRH showed antimicrobial activity for bacteria and yeast, with higher performance for bacteria than for yeast. Antimicrobial activity was not developed on paper coated with ALCRH by bar coater probably due to the evaporation of antimicrobial compounds of ALCRH from the paper surface with time. Saturation of paper with ALCRH was essential to develop antimicrobial activity on the paper. Dipping paper in ALCRH solution was recommended as one of the effective ways to make antimicrobial paper.

  • We examined the effect of the acidic liquid from carbonized rice hull(ALCRH) treatments to molded fiber packages(MFP) on weight, Haugh unit, pH and microbial activity of egg to extend the shelf life in egg packaging. Higher concentration and surface spray treatment of the acidic liquid extended the shelf life of egg. ALCRH treatment to MFP improved the performance of the packaging for egg in terms of decreased weight loss and retarded microorganism growth of eggs during storage.
