In an attempt to evaluate the effect of six starch sources-potato starch acetate, corn starch acetate, waxy corn starch, corn starch, potato starch, and wheat starch on properties of frozen noodle, amylograph characteristics of starch-wheat flour composites, cooking quality, maximum cutting force and sensory properties of cooked frozen noodles were examined. Compared with 100% wheat flour as control, potato starch acetate and potato starch-wheat flour composites had slightly lower initial pasting temperature and wheat flour composites with acetylated starches, waxy corn starch and potato starch had slightly higher maximum peak viscosity. At cooking quality examination of noodles made from wheat flour-starch composites, volume and weight of cooked noodles were increased and cook loss was decreased with the addition of acetylated starches and waxy corn starch. Maximum cutting forces of cooked frozen noodles containing more than 15% of potato starch acetate and only 15% of corn starch acetate were higher than that of control. Other starches except potato starch improved sensory properties of cooked frozen noodles and the greatest positive effect was acetated potato starch.

This study was conducted on a sampling of 700 mixed college students from seven different schools nationwide by written questionnaire to evaluate the value system of convenience foods among Korean college students. Korean students put value on the following categories of convenience foods in order; convenience, taste, price, appearance, appliance to daily life, variety, locality, nutritional value, originality, improvement required, cleanliness and tradition. Significant differences between the sexes occurred in categories as cleanliness and convenience, since females considered convenience foods as convenient but not so clean (safe to eat). This study also conducted factor analysis on 24 individual convenient foods. Noodles laid emphasis on nutritional value; where refrigerated foods, ready to eat (RE) side dishes, on-the-spot kimbab, and sandwiches focused on cleanliness. Noodles. cereal, and instant soup focused on price. Frozen pizza, noodles, retort, RE meat, ham, fish cakes were dependent on locality and traditionality. Noodles, instant food, and packed kimchi scored highly on convenience. Frozen fried rice, retort, instant porridge, instant rice, RE meat, cereal, instant soup, and RE side dishes on consumption on a regular basis. Cereal, refrigerated foods, and RE side dishes laid emphasis on taste. Noodles, instant rice, cereal, ham, and RE side dishes focused on variety. Retort, RE meat, ramen, cereal, ham, and on the spot sandwiches looked to originality, while canned foods was recognized as ‘needing improvement’.

In order to provide fundamental data on development of rice noodles, the quality characteristics of 10 kinds of commercial rice noodles were evaluated. Rice noodles were categorized into 3 groups for examination: 100% rice noodles with different shapes; round shape noodles with different rice contents; and noodles with different rice contents but smilar cooking method. Cooking properties, texture measurement, and sensory characteristics were evaluated. Frozen rice noodles and instant type of noodles made from composite flour of rice and wheat flour exhibited higher scores in overall acceptance. As for the form of noodle, round-shaped noodles seemed to be preferred in comparison to flat-shaped noodles. Generally, noodles with high texture scores of cohesiveness, adhesiveness, chewiness, resilience but not high score of hardness having smooth surface were preferred affecting overall acceptance scores. It appears that cooking methods and cooking time recommended by manufactures, noodle thickness and shape, packaging types such as frozen, refrigerated, and dried noodles were more influential than rice contents in aspects to the quality characteristics of the commercial rice noodle products in this study.

Cold buckwheat noodles with 3% vitamin D2 enriched Siitake mushroom and seaweed derived calcium (Aquacal) added as functional ingredients were developed. For the prediction of shelf-life of these cold buckwheat noodles, classified as unsterilized cooked noodles, bacterial counts and sensory evaluations were examined during 8 days under refrigerated conditions (5oC) and 8 weeks of storage under frozen conditions $(-18^{\circ}C)$. Results of bacterial count showed that cold buckwheat noodles were microbiologically safe within 6 days at the storage temperature of $5^{\circ}C$ and the shelf-life of these noodles could be extended to 8 whole weeks when stored at $-18^{\circ}C$. Apparent qualities (off-flavor and fungi development) of cold buckwheat noodles kept in $5^{\circ}C$ were not decreased within 8 days. Sensory characteristics (gloss, mushroom flavor, bitterness, chewiness and elasticity) of noodles were not changed during 8 weeks at $-18^{\circ}C$.

Optimal Chinese-noodle product in the aspect of preference and quality that added functionality, the focus was put on developing the stable high value-added product in a farm household. Experimental results showed that the value for infrared water-content analysis of moisture was $85.74{\pm}0.12%$, crude protein was $1.31{\pm}0.01%$, the crude fat $3.91{\pm}0.08%$, the ash $1.83{\pm}0.01%$, carbohydrate $1.08{\pm}0.03%$, and crude fiber $6.12{\pm}0.10%$. For all experiments with Chinese noodles, the grape peels were frozen and dried, powdered, and filtered with a 150-mesh strainer. The grape-peel powder, was added to the composite flour in a proportion of 0%, 1%, 3%, 5%, and 7%. The color of the cooked noodle appeared brown, demonstrating that the L-value decreased as the amount of grape-peel powder increased. The value of a, which corresponds to the level of redness, increased and the cooked noodle appeared brown as the amount of grape-peel powder added increased. The yellowness of the cooked noodle tended to decrease as the value of b, which corresponds to the level of yellowness, gradually (p<0.05). In the texture analysis, hardness was highest in the 7% grape-peel powder group, while the 5% groups showed the highest springness values. The 1% groups showed the highest cohesivness while the 7% groups were the chewiest. The 7% groups had the lowest stickiness values (p<0.05). It terms of sensory quality, the overall surface color, texture and taste were perceived as superior for the 3% grape-peel powder-added groups and lowest for the 7% group (p<0.001). The 3% treatment showed the best overall quality.

This study was conducted to investigate the surface spraying effect of materials on the rheological properties of frozen starch with microwave heating. Microwave helps reduce cooking time by high temperature, but swiftly snatches moisture from foods such as frozen starches (buns and noodles etc) and makes surface of foods harder. Four types of maltodextrin materials have been prepared for different concentration solutions and sprayed on surface doughs of sheet type. Sprayed dough samples were Quickly frozen at $-70^{\circ}C$ and wrapped with polypropylene film. All the treated samples were kept at 0, -20 and $-50^{\circ}C$, and then taken out periodically for measurement of the quality during storage. The quality attributes evaluated after heating with microwave energy include sensory quality retrogradation, texture, surface color and microstructure. The quality of frozen starches deteriorated with long term storage even at low temperatures of -20 and $-50^{\circ}C$, and the spray materials were found to improve the textural and physical properties of frozen starches in the microwave heating. Particularly, maltodextrin with D.E value of $9\~12$ had the most desirable effects of quality improvement.

This study examined the utilization of processed food and the recognition of food labels among 257 university students (201 females and 56 males) in Seoul and Kangwon-do. The results of the study showed that the most important considered information on food labels are shelf life, nutrition facts, and price in sequential order. Female students' recognition of nutrition facts was significantly higher than that of male students (p<0.05). Female students more attentively checked the manufacturer, origin of the products, and shelf life information on food labels than did the male students. In checking out the food labels information, the most checked items on food labels were calories, trans fatty acid and cholesterol in that order and the least checked information was the sodium contents. Among processed foods, male students' consumption was dominant in instant noodles, frozen dumplings, and canned goods, while female students had more candies/chocolates. In selecting processed foods, male students showed strong preference for cheaper and quantitative products, while female students chose more tasty, brand new, well-known brand, and products of domestic origin. Frequency of canned and frozen food consumption showed a positive correlation with BMI, while candies/chocolates showed a negative correlations with BMI. Negative correlations were found in the attitude of selecting food with longer shelf life and BMI. The results of this study suggest that university students need to be well informed to make wise food choices that contribute to a healthy diet. Additionally, food manufacturers and government authorities concerned should make certain that consumers know how to use food label information more easily and effectively through proper education.

This study was conducted to examine the consumption realities of processed food and the perception of food labeling with targets of university students attending schools in Daegu and Gyeongbuk areas. The reason for buying processed food was because it is easy to cook. As for the number of using processed food, it was answered that everyday dairy products, noodles, breads and snacks for 3~4 times a month, and meat processed foods, canned foods, sauces and frozen foods for 2~3 times a month. With regard to selecting processed products, both male and female students answered with taste and price first, barely considering the safety and nutritional elements. It turned out that they check the price, expiration date and country of origin in order upon buying processed foods. Most of them recognized food labeling, but answered that they checked it sometimes in order to check the 'expiration date' and the 'calories'. They were aware of the food nutritional contents indication. It was turned out that male students check it for nutrients and female students for weight control. The effect of the processed food indication was that it is easy to choose the necessary foods for health and as well as for comparing the food with other products. The satisfaction of the food labeling system was mediocre. The results indicated that the food indication system needs to be educated or promoted.

The results of this study on Purchase Patterns and Recognition of Processed Foods of School Meal Service Dietitians of elementary, junior and senior high schools in Chonbuk and Deagu Area are as follows : First, the rate of single cooking of the schools surveyed is 100% in Deagu and 66.9% in Chonbuk, and Chonbuk has more small-meal service schools which caused a higher labor cost than Deagu, Secondly, schools in Deagu has purchased not completely processed vegetables and fish and shells than Chonbuk, and Chonbuk(66.9%) has served more Kim-chi products than Deagu(41.6%). Thirdly, nutritional effects and preference have been considered as school dietitians make plans for the menu. Fourthly, the opinions of the school dietitians about processed food are in the order of high sodium content, convenience and the use of preservative, and Chonbuk has responded positively to the articles of future oriented quality, cooking usage and variety while Deagu has thought of it as an economical. The expected effects from the use of processed foods are in the order of saving labor time and student preferences. Fifthly, meat products have been frequently used and more frozen meat products have been used in Deagu and senior high school than Chonbuk and elementary and junior high schools, last, preferences on processed food are in the order of frozen sea food, noodles. dried sea food, processed vegetable and fruit, dairy goods and others. Senior high school dietitians have preferred packed meat products and other frozen processed food more than elementary and junior high school dietitians. The rate of serving processed food had a different depending on the number of students. In this study, dietitians recognize the harmful effects of processed foods over the merits, which means that the rate of using processed food is low. The proper usage of processed foods is thought to improve the preference of students, to have cooking time shortened and to help manage the meal service sanitarily and efficiently. Therefore, companies producing processed foods should do their best to develop safety and health oriented foods to gain the credibility, and the government should make new regulations for people to purchase and obtain processed foods without any doubt.

The aim of this study was to investigate effect of nutrition education methodology on consumption of processed food and personality of middle school students aged 14 to 16 years who live in Busan. We categorized questionnaire based on students' consumption of processed food and personality characteristics. Based on the above, we determined serum mineral level to validate the correlation between personal characteristics and quantifiable serum mineral level. Following adoption of a proper nutrient education methodology, we found that consumption of processed foods such as meat and meat products, frozen food, noodles, bread and snacks, and drink was significantly reduced. In addition, there were distinct changes in personality characteristics such as stability, governmentality, sociality, and responsibility that became markedly increased, whereas impulsiveness decreased. We found that these distinct nutrition- education-based changes were statistically significant, when compared before and after providing proper nutrition education. We interpret these results as group with low stability showed a high consumption of meat and meat products, noodles, bread and snacks, and drink, whereas group with high stability showed a high consumption of milk and dairy products. Similarly, we also found that group with low impulsiveness showed a high consumption of canned foods, whereas group with high impulsiveness showed a high consumption of meat and meat products, frozen food, noodles, bread and snacks. Our results indicated that serum Na after nutrition education decreased, whereas other minerals including Ca, Fe, Zn, Mg and K increased, when compared with before nutrition education procedure. This study suggests that nutrition education methodology and establishment of proper dietary educational programs keeping in view balanced dietary habits for middle school students would not only appear to make them get along with healthy dietary habits, but also change their personality characteristics.
