School foodservice customers are likely to be tired of repeated cycle menus and their satisfaction for meals offered in school is inclined to be low. The menu variety is an important factor in increasing customer satisfaction. The purpose of this study was to investigate customer perspectives for applying rice based bread menus in order to add menu variety and promote using rice processed products in school foodservice. The questionnaire was distributed to 760 parent samples in elementary schools and 520 student samples in middle/high schools and a total of 665 and 387 usable data were collected, respectively. Food habits such as preference for cooking method, menu preference, food allergy and nutritional perspectives for menu and customer perception for rice based bread like quality, reliability, price, and purchasing convenience were investigated using 7 Likert scale. Also expected menu types applying rice based bread and offering frequency of rice bread menu were examined. Preference level for bread-based meals were moderate and students' preferences were slightly higher than parents. Menu types applying rice bread expected by middle/high school students were western food (49.4%), spaghetti (28.4%), set menu (13.7%), noodle (17.6%), Korean food (11.1%), Chinese food (10.9%) and porridge (4.5%). The most occupied rate was once in a week for expected offering frequency. Most respondents perceived that rice bread was more nutritive and qualitative than the wheat based one.

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’.

Tarakjuk with different amylose content was made up using roasted rice flours that consisted of the highest enzyme-resistant starch (RS), while differential scanning calorimetry (DSC) was also utilized to measure the gelatinization temperature of these roasted rice flours in order to establish cooking temperature of tarakjuk. The following qualities of tarakjuk with different amylose content were studied: color, viscosity, spreadability, starch fractions involving total starch (TS), rapidly digestible starch (RDS), slowly digestible starch (SDS) and RS, in vitro starch digestibility (IVSD) and sensory properties. During experimentation, it was found that as the amylose content of the rice flour decreased, the L value of tarakjuk decreased, whereas a value increased significantly (p<0.05). Also, while viscosity showed to increase significantly (p<0.05), on the opposite end, the property of spreadability decreased. TS ranged from $15.95{\sim}17.31%$, RDS $9.36{\sim}10.16%$, SDS $5.46{\sim}6.91%$ and RS $0.33{\sim}1.07%$, on a dry basis. Although the amylose content of rice flours decreased, IVSD increased, however showing no significant difference. When testing the sensory properties of tarakjuk, color and viscosity increased, whereas clumpiness decreased. Ilpum tarakjuk showed the highest score for nutty taste and overall acceptance levels. In fact a high correlation was shown between nutty taste and overall acceptance level (p<0.01), which leads one to believe that nutty taste is a prime factor that greatly influences overall acceptance. Furthermore, viscosity was positively correlated with both a and b values, however negatively correlated with L value (p<0.05). Moreover, roasted nutty taste and overall acceptance were positively correlated with a value (p<0.05), respectively. In conclusion, the above results suggest that tarakjuk could be made by choosing the appropriate rice flour based on the nutritional or sensory purpose.

RS 함량이 가장 높은 볶은 일품 멥쌀가루를 사용하여 DSC로 호화온도를 측정하여 타락죽의 가열조건을 설정하였다. 이로부터 설정된 가열조건을 이용하여 타락죽의 differential scanning calorimetry(DSC) 특성과 X선회절도에 의한 결정성, 효소 저항전분(enzyme-resistant starch, RS) 함량과 in vitro 전분분해율(IVSD) 그리고 아미노산 조성과 in vitro 단백질 분해율(IVPD)에 대한 가열온도와 시간의 영향을 측정한 결과는 다음과 같다. 가열조건을 달리한 타락죽은 $185^{\circ}C$에서 25분 볶은 일품 멥쌀가루를 사용하여 50, 56.5, 64 그리고 $69^{\circ}C$에서 각각 30과 60분, 60과 120분, 120과 240분, 240과 300분 가열하여 제조하였고, 재래식으로 10분간 끓여서 만든 타락죽을 대조구로 하였다. DSC로 측정한 결과 50와 $56.5^{\circ}C$에서 가열한 타락죽은 $63.7-125.2^{\circ}C$의 온도범위에서 두개의 열전이를 나타내었는데, 이들은 각각 아밀로펙틴의 용융$(63.7-73.8^{\circ}C)$과 AM-lipid 복합체의 용융$(97.7-125.2^{\circ}C)$에 해당한다. 반면, 가열온도 64와$69^{\circ}C$에서는 $96.9-127.6^{\circ}C$에서 AM-lipid 복합체 용융을 위한 한 개의 열전이를 나타내었다. 또한 AM-lipid복합체 열전이를 위한 용융엔탈피는 가열조건에 따라서 대조구의 14.22J/g보다 낮은 것으로 나타나 대조구에서 AM-lipid 복합체 형성이 가장 많은 것으로 생각된다. X선회절도에 의하면 타락죽은 가열온도 50와 $56.5^{\circ}C$에서는 일부 회절각도에서 피크가 잔존하였다. 타락죽의 RS함량은 가열온도가 증가할수록 50>56.5>대조구>64>$69^{\circ}C$의 순서로 감소한 반면, IVSD는 50<56.5<대조구<64<$69.5^{\circ}C$의 순서로 증가하였다. 타락죽의 총아미노산 함량은 가열조건에 따라서 11,558-15,601mg/100g을 나타내었으며 $56.5^{\circ}C$에서 120분 가열 시 가장 높았다. Lysine과 tryptophane과 같은 필수아미노산 함량은 가열온도 50와 $56.5^{\circ}C$에서 재래식으로 끓여 제조한 타락죽보다 높았다. 한편 타락죽의 IVPD는 모두 대조구보다 증가하였다.

The purpose of this study was to investigate middle school boys' and their parents' preference on menu types of school breakfast. School breakfast was served at a boys' middle school in Gyeonggi-do, Korea for 7 weeks. Ten types of convenient menus, including steamed rice, rice porridge, rice cake, bread, or cereal, were served to 200 students free of charge. After the service period ended, questionnaires were distributed to the students and their parents. Usable questionnaires were returned by 142 (71%) students and 124 (62%) parents. About two-thirds (66%) of the students and about half (51%) of the parents preferred convenient menus to traditional menus as school breakfast. The students were the most highly satisfied with the menu type including hot dog buns whereas the parents regarded these as neither appropriate nor inappropriate as school breakfast. Overall, the menu types including steamed rice such as Kimbap or rice balls were highly ranked in terms of the students' level of satisfaction as well as the parents' level of appropriateness evaluation. About 20% of the students and 50% of the parents expressed intention to eat or make their children eat school breakfast even if payment is required. Over two-thirds of both the students (70%) and parents (68%) responded that less than 1,500 won per meal would be the appropriate price of school breakfast. The results of this study show that convenient menus could be considered as alternatives to traditional menus in school breakfast service, although additional efforts are necessary to develop such menus to satisfy both the students and their parents.
