Ramyen and Korean noodles (guksu) are popular foods in Korea and around the world. Since 1998, rice consumption in Korea has gradually decreased, whereas consumption of noodles has continuously increased. The purpose of this study is to assess the consumption of ramyen and Korean noodles of Koreans, using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2007. Korean adults (>20) were selected to examine the associations between noodle consumption and food and nutrient intake and health status. SAS 9.1 and SUDAAN 9.1 were used for the data analysis. 10.3% of Korean adults consumed ramyen, and 15.4% consumed Korean noodles. The consumption of ramyen and Korean noodles were higher in men than in women, in lunch than in other meals, and in the lowest income quartile than the highest quartile. Ramyen and Korean noodle consumer groups consumed more grain products, seasonings, and oils than the nonconsumer group. The noodle group showed significantly lower systolic blood pressure than the non-consumer group. The noodle groups showed lower rates of hypertension and metabolic syndrome than the non-consumer group. From these results, we conclude that ramyen and Korean noodles may have positive health effects. More studies on the association between noodles and the health of Koreans and those in other countries should be done in the future.

This study was designed to estimate the effect of ethanol addition on shelf-life extension and changes in growth of total aerobic bacteria in fresh wet noodles. The wet noodle was made with addition of 0, 1 and 2% ethanol. During the storage at 10oC, wet noodles were monitored changes in the total numbers of aerobic bacteria. A 6 log cfu/g was applied as a standard for microbiological quality of foods. As a result, the shelf-lifes of wet noodle with addition of ethanol at the standard were 9.17 days at no ethanol, 15.02 days at 1% ethanol and 27.03 days at 2% ethanol. The respective percentage increases in the shelf-life observed at both 1 and 2% ethanol addition were 63.8% and 194.8% comparing with no ethanol treatment. Consequently, addition of ethanol into fresh wet noodle inhibited growth of total aerobic bacteria and extended shelf-life.

Some biological activities such as an electron donating capacity, the contents of total polyphenol compounds and flavonoids, fibrinolytic activity and α-glucosidase inhibitory activity have been detected in hot water extracts of Ligularia fischeri and Angelica gigas Nakai. To increase the usefulness of the functional ingredients for prevention and improvement of some metabolic disorders, ethanol-treated hot water extracts of Angelica gigas Nakai were prepared. A hot water extract of Ligularia fischeri has 92% of electron donating capacity, 39.4 mg/g of total polyphenol compounds, 24.8 mg/g of flavonoids and 29.8% of α-glucosidase inhibitory activity, but no fibrinolytic activity. A hot water extract of Angelica gigas Nakai has 94.7% of electron donating capacity, 5.8 mg/g of total polyphenol compounds, 2.6 mg/g of flavonoids, 0.48 plasmin units of fibrinolytic activity and no α-glucosidase inhibitory activity. However, with partial purification using cold ethanol treatment, the α-glucosidase inhibitory activity of Angelica gigas Nakai was increased to 70.5%. Thus, we expected a more useful effect with the use of the addition of a cold ethanol-treated Angelica gigas Nakai extract. The L, b values of cold buckwheat noodles using a mixture of 0~3% of Ligularia fischeri powder and 0.5% of an ethanol-treated hot water extract of Angelica gigas Nakai were decreased with the addition of an increasing amount of Ligularia fischeri powder. Among the mechanical qualities, only adhesiveness was significantly higher in 3% Ligularia fischeri noodles. From sensory evaluation data, it was determined that these two functional ingredients did not ruin the color, texture, and overall acceptance of the cold buckwheat noodles. A higher amount of the extracts improved the quality of the product with little added cost.

The new colored noodles were produced by utilization of cuttlefish ink, beetroot juice and/or spinach juice in this study and the physico-chemical and sensory properties of the developed noodles were investigated before and after cooking. The weights of fresh noodles increased 2.36~2.22 times by moisture adsorption after cooking. Moisture adsorptions of the cooked noodles were higher in the cooked noodles with higher contents of additives and ranged 136 to 144%. The colors of the all fresh noodles and the cooked noodles containing cuttlefish ink or spinach juice were highly acceptable. The tensile strength was highest in the cooked noodle containing 2% cuttlefish ink, which was 9 folds higher than regular noodle. The % elongations were highest in the regular cooked noodle and the cooked noodle containing 4% cuttlefish ink. In the textural property assays of cooked noodles, the cooked noodle containing 10% beetroot juice had higher values in hardness, chewingness and gumminess than the regular noodle. The cohensiveness was highest in the cooked noodle containing 6% spinach juice. The adhesiveness of the regular cooked noodle was significantly high, compared to any developed noodle. The differences in springinesses of developed noodles were ignorable. The overall textural properties were influenced by the additives in noodles, however, the effects of concentrations of the additives were insignificant. The results of the sensory tests showed the highest values of all descriptions in the cooked noodles containing 4% cuttlefish ink or 10% spinach juice, indicating the highest acceptability.

The purpose of this study is to understand the Chinese noodles(mian tiao). Wheat seems to have been cultivated 3-4,000 years before according to the archaeological evidences from the neolithic sites. The five grains(rice, millet, beans, barley, barnyard millet) already appeared in the period prior to Chin dynasty and were used as whole grain, but it was not until Chun Chu Zhan Guo period that the introduction of the flouring method stimulated the cultivation of wheat. In Chin-Han period, when water power and animal force were put into usage to facilitate the mass production of wheat flour, 'Bing', a designation for all the food made of wheat first appeared in the literature, and it was this 'Bing' that had later developed into noodles. In Wei Chin Nan Bei Chao period, roasted 'Bing', namely 'Kao-Bing' made its first appearance, and in Tang period, various noodles were created with the increase of restaurants specialized in noodles. In Song dynasty, 'La-Mian', the noodles stretched and beat from noodle dough, was first introduced, and in Yuan period, invention of drying method made the appearance of dried noodles, 'Gua-Mian', possible, which was good for easy and long preservation. Qing dynasty developed the noodles with a variety of assorted ingredients. The Chinese noodles are classified by various standards such as main ingredients, cooking methods, kinds of sauce, secondary ingredients, shape, eating method, flavor, and look.

Palm 유로 유열처리한 라면제품을 태양광선구, 실내보존구, 항온기보존구 및 골판지상자구 등의 처리구로 나누어 20주동안 저장하고, 경시적으로 산가, 과산화물가, TBA가, 지방산조성 및 요오드가 등의 지방산화이상을 조사한 결과는 다음과 같다. Al증착 film포장지로 밀봉하고 골판지상자에 넣어 실온 암소에서 저장하면 산가, 과산화물가, carbonyl가 및 TBA가는 완만하게 증가하여 5개월 경과 후에도 완전한 품질을 보였다. 관능검사에 있어서의 산패취도 5개월후까지는 인정되지 않았다. 실내보존구 및 항온기 보존구의 라면은 완만한 산화이상을 보여 저장 18주에 산패취를 확인하였으나, 태양광선구의 라면은 저장 10주부터 다소 크게 산화가 일어났으며, 이때 산패취를 확인하였다. 산가, 과산화물가, carbonly가, 및 TBA가는 각 처리구 공히 저장기간 동안 증가하였으며, 태양광선구에서 그 증가이상은 현저하였다. 특히 TBA가는 태양광선구에서 저장 10주이후 급격히 증가하여 14주에 그 정점을 이루고 다시 감소하였다. 저장초 그리고 저장 18주의 태양광선구 및 항온구의 라면 유지에 대한 지방산 조성을 살펴본 결과 항온구에선 큰 변화가 없었으나 태양광선구에선 저장초의 지방산조성에 비하여 oleic acid등 불포화지방산의 상대적인 감소이상을 볼 수 있었으며 저장 중 요오드가의 감소가 이런 사실을 뒷받침하고 있다.

Yellow alkaline noodles were prepared with various Korean wheat cultivars including different protein and amylose contents and made from two types of noodle machines. Korean food companies and restaurants generally used noodle machine made in Korea, whereas research institutes mainly practiced with noodle machine made in Japan. Noodle dough sheet from Korean machine showed 5% higher water absorption and 30 min shorter resting period than the noodle dough from Japanese machine because of the difference of size and weight of roller in two types of the machines. In 15 Korean wheat cultivars, thickness of noodle dough sheet was positively correlated with protein content and mixograph water absorption regardless of both types of the machines. Cooked noodles from Korean machine showed higher hardness and lower springiness than noodles from Japanese noodle machine, but difference in cohesiveness of cooked noodles was not found between two different noodle machines. In the three Korean wheat cultivars with different protein content, thickness of noodle dough sheet was also positively correlated with protein content, SDS sedimentation volume and mixing time of mixograph in both types of the machines. The more protein content increased, the more hardness of cooked noodles increased regardless of both types of the machines. However, springiness and cohesiveness of cooked noodles were not significantly correlated with protein content. In waxy and partial waxy wheat cultivars, lightness of noodle dough sheet from Korean noodle machine positively correlated with amylose content. Amylose content and setback in pasting properties were positively correlated with hardness, springiness, and cohesiveness of cooked noodles while both damaged starch and breakdown were negatively correlated with those.

본 연구에서는 기능성 부여와 저장성이 증진된 국수를 개발하고자 양파분말을 국수에 첨가(0, 3, 5, 10%)한 후 품질특성과 저장성을 조사하였다. 양파 생면의 수분은 양 파분말 첨가량의 증가에 따른 차이는 없었으나 pH는 감소 하였다. 양파 생면의 조리 후 중량과 부피, 수분흡수율은 대조구와 양파분말 첨가군 간에 차이가 없었다. 색의 경우 생면은 양파분말 첨가량이 증가할수록 L값과 a값은 감소하 고 b값은 증가하였으나 조리면은 큰 차이를 나타내지 않았 다. 생면의 총 폴리페놀 함량과 DPPH radical 소거능은 양파 분말 첨가량이 증가함에 따라 증가하였으며 조리후에는 함량이 전체적으로 감소하였으나 생면과 동일한 경향을 나타내었다. 양파 조리면의 조직감의 경우, 경도와 씹힘성 은 대조구가 양파 첨가군에 비해 높게 나타났으나 탄력성은 대조구와 양파분말 첨가군 간에 차이가 없었다. 생면을 1 0℃에서 12일간 저장하면서 총균수를 측정한 결과 양파분 말 첨가군은 대조구에 비하여 저장성이 최소 6일 이상 연장 될 수 있었으며 그 중 양파분말 5% 첨가구가 가장 효과적인 것으로 간주되었다. 양파 조리면의 관능검사 결과 외관, 맛, 냄새, 조직감 및 전체적인 기호도는 대조구와 양말분말 첨가군 간에 차이가 없었다. 따라서 본 연구결과로 볼 때 양파분말을 국수에 5% 첨가함으로서 기능성 부여와 저장 성이 증진된 국수를 개발할 수 있으리라 생각된다.

국수를 만들 때 다양한 기능성을 가진 어성초의 적절한 첨가 비율을 알아보기 위하여 어성초 분말을 첨가한 복합분의 점도 특성, 국수를 만든 다음 조리시험, 관능검사를 실시하였다. 어성초 분말을 첨가한 복합분은 대조구에 비하여 호화개시 온도, 최고점도, 95℃에서의 점도가 낮아졌다. 그러나 최고점도와 95℃에서 15분 후의 점도와의 차이는 그다지 크지 않았다. 어성초 분말을 첨가한 조리면은 대조구에 비하여 중량과 부피가 감소하였으나 어성초 분말 0.5%, 1.5% 첨가구는 중량에 있어서 대조구와 유의적인 차이를 나타내지는 않았다. 어성초 분말을 0.5% 첨가한 국물의 흡광도는 대조구보다 낮았으나 다른 어성초 분말 첨가구는 대조구보다 높았으며, 유의적인 차이를 나타내었다. 어성초 분말의 첨가량이 많을수록 조리면의 L값은 감소하였으나 a값과 b값은 증가하는 것으로 나타났다. 관능검사에서는 어성초 분말을 첨가한 시험구의 색도가 대조구보다 낮았으며, 유의적인 차이를 보였으나 전체적인 기호도에 있어서는 대조구, 어성초 분말 0.5%, 1.5%가 유의적인 차이를 보이지는 않는 것으로 보아 어성초 분말을 첨가한 국수 제조시에 0.5%까지 첨가하는 것은 국수의 품질에 큰 영향을 주지 않을 것으로 생각된다.
