The aim of this investigation was to examine the antioxidation, physicochemical, and sensory activity of a Korean steamed-rice cake, Sulgidduk, fortified with water extracts from Moringa oleifera (M. oleifera) leaf. M. oleifera leaf extracts were added to rice powder at rations of 0.1%, 1% and 10%. To examine antioxidation properties, the scavenging activities of DPPH radicals, hydroxyl radicals, ABTS+ radicals, and ferric ion reducing antioxidant power were investigated. M. oleifera extracts significantly increased the antioxidation activities of Sulgidduk in a dose dependent manner (p<0.05). Physicochemical characteristics were measured by proximate composition, color, texture profile analysis, and sensory evaluations. As the concentration of M. oleifera leaf extracts increased, L-values and a-values significantly decreased while b-values increased. Texture profile analysis demonstrated that the control groups showed significantly higher values for hardness, cohesiveness, chewiness, and adhesiveness as compared with groups containing M. oleifera leaf extract (p<0.05). In the sensory evaluation, the sample containing 0.1% of M. oleifera leaf extract obtained the best results in overall preference. Taken together, these results suggest that M. oleifera leaf may have the potential to increase the consumer acceptability and the functionality of Sulgidduk.

This study investigated the quality and antioxidative properties of a Korean steamed-rice cake, Sulgidduk added with Prunus yedoensis Matsumura extract, and vitamin C. Sulgidduk was prepared by adding Prunus yedoensis Matsumura extract at 0, 0.1, 0.2, and 0.3% of rice powder. Antioxidant activities were measured by the scavenging activities of DPPH radicals, $ABTS^+$ radicals, $superoxide^-$ radicals and the reducing power. For analyzing quality characteristics, proximate composition, color, texture profile analysis, and sensory evaluations were measured. The antioxidative effect of the Sulgidduk significantly increased as the addition level increased, compared to the original Sulgidduk (p<0.001). As the content of Prunus yedoensis Matsumura extracts increased, L-values significantly decreased while the a-value and b-value significantly increased (p<0.001). For the texture profile analysis, the control group had a significantly higher value for hardness as compared to the Prunus yedoensis Matsumura extract-added groups (p<0.05). Springiness, chewiness and adhesiveness were not significantly different among the samples. In the sensory evaluation, the samples containing 0.1% and 0.2% Prunus yedoensis Matsumura extracts obtained better results in attribute. From these results, we suggest that Prunus yedoensis Matsumura is a good ingredient for increasing the consumer acceptability and the functionality of Sulgidduk.

'The Joobang' is a cooking book written purely in Korean which came from a Mr. Lee. It is unknown when and by whom this book was written, but it is inferred from red pepper mentioned in this book and from Korean-writting type that the book was written around in the mid-nineteenth century. The contents of 'the Joobang' consist of thirty seven items in all : sixteen items of rice alcoholics, five side dishes, eleven Tucks(rice cakes) and Guaja(cookies) and five processed materials. Cereals for making rice alcoholics were regular rice and sticky rice. In the first brew, rice alcoholics is made all from regular rice, and in the second brew, fifty six percent of regular rice and forty four percent of sticky rice was made use of. For five items of alcoholics forming 31.3% of alcoholics, flour was added, in which case the proportion of leaven to cereals was lower. There were four types of processing cereals in brewing rice alcoholics Jee-ae-bop(steamed rice, 60.9%), thick gruel with cereals ground and completely cooked(8.7%), thick gruel with cereals ground and half cooked (26.1%) and GooMung Tuck(doughnut-shaped rice cake, 4.3%). The comparison of the materials for brewing rice alcoholics and of the types of processing cereals presented in the seven cooking books purely in Korean(Umsik Deemeebang, JoobangMoon, Umsikbo, Sool-mandununbop, Kyuhap chongseo. The Kims' Joobangmoon and The Lee's Umsikbup) showed us the following facts ; Yihwajoo (rice alcoholics brewed around the blooming time of pear trees) and Kwahajoo(rice alcoholics which passed the summed time) were most often introduced and commonest, and the materials for brewing and the types of processing little changed over times. The materials for side dishes were all animal food, and vegetable food was little used for side dishes. Red pepper was used for seasoning. It is a problem of Korean traditional cooking that there were no units of measuring for side dishes. The main materials for Tuck(rice cakes) and Guaja(cookies) were sticky rice, regular rice and honey. There was a variety of terms for the process, from which we can see that the procedures of making Tuck(rice cakes) and Guaja(cookies) were very complicate. Processed materials were chiefly made of sticky rice and the material of firewood(oak trees) and the strength of fire(fire burning vigorously and fire turning to ashes) were described.

일본(日本) 내량시대(奈良時代)를 대표(代表)하는 춘일대사(春日大社) 약궁제(若宮祭)는 한반도(韓半島)와 종교적, 문화적 문류(文流)가 빈번하던 시대에 형성된 등원가(藤原家)의 씨사(氏社)로서의 제사이며 역사적(歷史的)으로도 백제인(百濟人)과의 관계가 밀접하여 삼국시대(三國時代)의 식생활(食生活)을 연구하는데 좋은 자료가 되리라 보아 조사한 것이다. 1. 좌속신(坐俗神), 불교(佛敎), 유교식(儒敎式) 제사(祭祀) 및 경사스런 축하연에 쓰이는 종이, 실크, 떡으로 만든 조화(造花)장식은 최초에는 계절에 맞는 생화(生花)를 쓰다가 차츰 다양하게 변화했음이 보인다. 본(本) 약궁제(若宮祭)에서의 도라지꽃은 한반도에서 쓰여진 흔적이 없으나 일본(日本)에서는 제사(祭祀)로 쓰였다. 2. 소(小), 대어반(大御飯)은 시루떡의 시작이였고 백미(白米) 이전에는 현미(玄米)로 만들었다. 다시 쌀 외에 찹쌀, 팥 등 여러가지 곡물을 가미하게 됐다. 3. 채소의 종류는 근채류(根菜類)가 귀중한 채소로 꼽혔고 극히 단순한 조리법이였으리라 본다. 4. 당과자(唐菓子)는 쌀가루를 여러가지 형을 만들어 쪄서 튀겨서 먹는 것으로 보아 그 이후의 과자와 전병의 원조임을 알 수 있다. 5. 8의 어과자(御菓子)에서 둥근 메떡은 현재의 절편이나 가래떡의 시작이였으며 일본(日本)은 기호상 찰떡으로 변했다고 본다. 6. 제사에 최근에도 쓰여지는 곶감, 밤은 고대(古代)부터 이어온 식품으로 밤은 그 껍질채로 쓰여졌고 그 외의 그 지역에서 생산되는 갖가지 과일이 쓰여진 것으로 본다. 7. 염분(染分)과 사색(四色)은 적(赤), 황(黃), 청(靑), 백색(白色)을 말하며 그 색채가 원시적인 선명한 색깔로 본제(本祭)의 상징이며 대표적인 제물이다. 한반도에서는 과자, 사탕, 떡, 과일 등을 주로 이 4가지 색깔로 물들여 제사뿐만 아니라 경사스런 잔치에도 높이 고여서 축하의 뜻으로 차렸다. 8. 성물(盛物)에서는 검은콩, 흰콩, 팥, 비자로서 그 당시 중요한 곡물로서 나타났다. 9. 술은 청주(淸酒)를 쓴 것으로 보아 이미 그 시대의 고도(高度)의 제조법이 백제로부터 전해져서 현대까지 이어지고 있음을 보여준다. 끝으로 신찬(神饌)과는 직접적인 관계는 없으나 사진 1, 2, 3에서 보여주듯이 직접 본(本) 행사(行事)에 참여하면서 제단형태, 의상, 절차, 그 외의 음악과 무용, 장식 등이 현존하는 한국의 전통적 풍물과 그 분위기에 이르기까지 밀접한 관계가 있었음을 느낄 수 있었다는 점이 본 제사를 통하여 고대식(古代食)을 추정하는데 간접적인 뒷받침이 될 수 있다고 보았다.

The objective of this study was to investigate the effect of occasional mid-morning snacks (MMS) on dietary behaviors and school life among elementary students. The students, mothers, and teachers from two elementary schools in Seoul were selected. The schools have been provided a steamed sweet-potato or potato, or a piece of rice-cake or cake with a pack of milk as MMS 3-4 times a month for more than 3 years. Most students were satisfied with the MMS. Mothers and teachers reported that their children or students were happier, more active, and more energetic in school with MMS. Furthermore, the students answered that they could drink milk better on the day when the school provided MMS. Many students felt that it was relevant to serve a simple menu at lunch time if they were served MMS. Also, students became more interested in school meals or foods with MMS. In addition, mothers who had jobs wanted more frequent MMS. The degree of satisfaction about MMS of the teachers was higher than that of students or mothers. Many teachers thought that their students drank milk better with MMS and further, that it made students to drink more milk on other days. In conclusion, MMS had positive effects on the dietary behavior and school life of elementary students. Therefore, it can be a good option for eliminating skipping breakfast because it provides more nutrition, makes students drink more milk, and allows students to enjoy school activities more.

This study was conducted to investigate the effects of paprika juice on the quality characteristics of Jeung-Pyun (fermented and steamed rice cake). Jeung-Pyun was prepared with four different levels of orange paprika juice (0%, 10%, 25% and 50% replacement of water). The proximate composition analysis showed that moisture contents of Jeung-Pyun were 48.72∼49.36%, and crude protein, lipid and ash contents were 2.94∼3.13%,0.46∼0.63% and 0.60∼0.65%, respectively. The pH of Jeung-Pyun batters was decreased from 4.74∼4.83 to 4.27∼4.38 during 4 hours of fermentation at 35$^{\circ}C$. The maximum expanded volume was observed in control group, followed by 10% group, 25% group and 50% group and the volume expansion was decreased with the increased amount of paprika juice. The "L" value (lightness) was the highest in control group and decreased with paprika juice addition, while the "b" value (yellowness) was increased as the amount of paprika juice was increased. Rheology test showed that there were no significant differences in hardness an cohesiveness among four groups. Springiness and gumminess were the lowest in control group and increased with the increased amount of paprika juice. Results of sensory evaluation showed that there were no significant differences in scores of cell uniformity, sweetness, moistness and overall desirability between control and 10% group. Therefore. Jeung-Pyun prepared with 10% paprika juice was evaluated as the most acceptable one among test groups when compared to control.
