본 연구에서는 식품포장재로 이용되는 재활용 및 비재활용 종이류가 안전한지를 평가하기 위해 식품공전 규격에 준하여 실험하였다. 식품포장재 중에서도 피자상자를 선택하였는데, 이는 피자가 고온에서 조리되어 포장되며 다량의 기름 성분을 함유하여 오염물질이 이행될 가능성이 상대적으로 높을 것으로 예상됐기 때문이다. 식품공전에서는 PCBs, 납, 카드뮴, 수은, 6가크롬, 비소, 포름알데히드 및 형광증백제의 허용 잔존농도를 정하여 식품포장재로 이용되는 종이류에 잔존하는 유해물질을 규제하고 있다. PCBs의 여섯개의 표준품과 모든 시료의 피크가 일치하지 않았으므로 피자상자에는 PCBs가 잔존하지 않는 것으로 판단된다. 카드뮴, 수은, 6가크롬에 대한 재질규격 평가를 위한 분석이 추가적으로 필요하다고 사료된다. 비소와 납은 모든 시료에서 기준치의 10배 이하의 양이 검출되어 식품포장재로 사용되었을 때 안전성에 큰 영향을 미치지 않을 것으로 판단된다. 포름알데히드는 모든 시료에서 기준치보다 낮은 농도로 검출되었지만 잉크를 많이 함유하고 있는 표면에서 미량이지만 상대적으로 높게 검출되었다. 형광증백제는 비재활용 종이 소재의 상자에서는 검출되지 않았다. 그러나, 상자 내 피자 포장 유무나 잉크의 함량 정도에 상관없이 재생용지로 만들어진 상자 시료에서는 형광증백제가 검출되었다. 형광증백제는 불검출이 기준이므로 포함된 재활용지를 식품 포장으로 이용할 때는 식품과의 직접 접촉을 피하기 위해 중간에 안전성이 입증된 간지 등을 삽입하는 방법을 사용하여 최종 식품의 안전성에 영향을 주지 않는 것이 바람직할 것이다.

This study was surveyed by 318 male and 288 female college students eating out behaviours in Seoul. The results were summarized as follows; 1. Listed below are the major kinds of eating out of the home, breakfast form 8.9%, lunch 76.9%, supper 24.5% and snacks 25.7%. 2. 'Lunch out everyday' by male 53.5%, by female 52.5% 3. The reason why they lunch out indicates carrying a lunch box is 'inconvenient' by 35.1%, 'convenient' by 32.2%, 'hard to prepare the lunch box' by 19.9%. 4. When they choose kinds of food they are ascribed to 'preference' by 66.5%-74.6% the highest percentage of all. 5. The percentage rate of families who eat out Korean food gained the highest percentage by 59.7% next western food 16.6%, chinese food 15.2%, but the lowest percentage was Japanese food by 4.3%. 6. Ra-myun and noodles occupy the highest percentage of male by 43.7%-40.6%, female by 32.4%-54.3%. 7. When viewed from food preference for eating out take fried chicken, Pizza, Kalbi, Bulkoki and Tangsuyook. 8. The price the students generally pay for lunch was 500-1400 wons, averages to 1,000 wons. The price of eating out per capita a day, when taken by family unit averages to 5,200-5,900 wons. 9. College students offered suggestions for 'expensive in prices' 59.1%, 'Unsanitary' 14.1% when eating out.

This survey was conducted to assess dining-out behaviors and menu preferences of university students in the Seoul area. The results were as follows: 1. 65.2% ate out rarely for breakfast and 73.1% ate out frequently for lunch, whereas 20.9% occasionally ate out for lunch. The frequency of dining out for breakfast was influenced by age, gender, and major but the frequency of dining out for lunch was significantly correlated with age(P < 0.01). 79.2% of females dined out frequently, but 62.3% of males reported doing so(P < 0.001). 65.2% ate out frequently for dinner and 31.6% did so occasionally. 34.2% dined out frequently for snacks, and 53.5% did so occasionally. 2. Factors to consider in dining out were as follows: taste > preference > price > persuasion > nutrition. The motivations for dining out were as follows: convenience > favorite food > difficult to prepare lunch box > difficult to carry lunch box > habit. This factor was correlated significantly with age(P < 0.05) and residence type(P < 0.001). Problems with dining out were listed as follows: unbalanced nutrition > price > sanitation > variety of menu > taste. This factor was correlated significantly with age(P < 0.05), alcoholic beverage use(P < 0.01) and smoking(P < 0.01). 3. Foods selected for meals when dining out were as follows: Korean style > Western > Japanese > noodles > Chinese. The expense(in won) of dining out for lunch was as follows: 3,000${\sim}$5,000 > 2,000${\sim}$3,000 > over 5,000 > under 2000. Problems to be corrected in Korean-style food were as follows: variety of menu > price > using personal dish. 4. Korean foods preferred in each cooking style when dining out were as follows: beef rib > kimchi-jjigae > bulgogi > doenjang-jjigae > bibimbab. Chinese foods selected were as follows: tangsuyuk > jajang myeon > jjambbong > gganpunggi > bokeumbab. Preferred Western foods were as follows: spaghetti > steak > pork cutlet > pizza > ribs > chicken. Preferred Japanese foods in meals when dining out were as follows: sushi > hoe > udong > pork cutlet > soba. Preferred noodle foods selected when dining out were as follows: ddukboki > ramyeon > mandu > guksu > sundae > gimbab >. Preferred baked foods for dining out were as follows: cake > pizza > loaf bread > baguette > sandwich > hamburger > doughnut > cream bread.
