  • 본 연구에서는 키토산 분자량 약 120 kDa을 농도별로 제조한 후 양념 우육에 첨가하여, 양념 우육의 보존성 및 품질향상 효과를 알아보기 위하여 생균수, 지질 산화도, pH, 색도와 보수력을 측정하였다. 저장기간이 경과함에 따라 생균수는 증가하였으며, 키토산을 첨가한 것은 첨가하지 않은 것에 비해 생균수가 적은 것으로 나타났다. 또한 저장 10일째 키토산을 전혀 첨가하지 않은 양념 우육은 생균수가 $10^{7}$ cfu/g까지 증가한 것에 비해, 키토산을 0.1%이상 첨가한 양념 우육은 $10^{5}$ cfu/g정도로 나타났다. 따라서 키토산의 첨가농도가 증가할수록 저장성은 향상되었으며, 키토산을 0.1%이상 첨가하였을 경우에는 첨가하지 않은 것에 비해 저장성이 상당히 유지되는 것으로 나타났다. TBARS의 경우 저장기간이 경과함에 따라 함량은 증가하는 경향을 나타냈으며, 키토산을 첨가한 경우 첨가하지 않은 것에 비해 TBARS의 함량이 낮게 나타났다. 또한 키토산의 첨가 농도가 증가할수록 TBARS의 함량은 낮게 측정되었으며, 키토산을 0.5% 첨가하였을 때 산화억제효과가 있었으나,1.0% 첨가 시 첨가하지 않은 것에 비해 산화억제 효과가 매우 큰 것으로 나타났다. 양념 우육의 색도 변화를 살펴보면, 키토산을 첨가한 양념 우육은 첨가하지 않은 것에 비해 적색도가 높게 유지되었다. 양념 우육의 보수력은 키토산을 첨가한 양념 우육은 저장 초기 낮게 나타났으나 저장 중 안정되게 유지되었다. 이상의 결과에서 볼 때 분자량 약 120 kDa의 키토산을 0.1%이상 양념 우육에 첨가하면 저장성 및 품질유지 효과가 있는 것으로 사료된다.

  • This study investigated the main dishes of menus at university faculty cafeterias to understand current lunch menu trends. A sample of 1040 menus was collected from Internet homepages of 52 universities between March and May, 2014. The main dishes of menus were categorized into six groups based on main ingredients and cooking methods. The most frequently served main dish ingredient was pork followed by fish/seafood, and poultry. Pork dishes and chicken dishes were mainly roasted, pan fried, or deep fried with various carbohydrate ingredients to bulk them up. Large amounts of chili pepper, corn syrup, and oil were added to improve the bland flavor of these dishes, which contain starchy ingredients. In contrast to pork dishes or chicken dishes, 40.2% of beef dishes was served in a more traditional way as soup. Fewer kinds of fish or seafood were used, and the cooking methods also lacked diversity. In conclusion, main dish menus at university faculty cafeterias have undergone changes in terms of ingredients and cooking methods. Meat dishes cooked using traditional methods are becoming less common, especially for pork and chicken dishes, which are quite sweet, salty, and spicy. Extensive use of carbohydrate ingredients was found in some meat dishes and side dishes in one-dish meals.

  • This study was carried out to obtain the menu preferences of frequently served set menu of the staff working at Samsung Medical Center. The frequently served set menus were 72 menus including 23 Korean meals, 12 bowel of rices, 18 noodles, 10 soups, 6 fried rices, 3 western meals. The subjects of this study were 624 staffs who works at Samsung Medical Center. The results are summarized as followers : The subject group for this study was composed of 23% males and 58% females, 80% of subjects are twenties and thirties. The best preferred menu was fried food 4(boiled rice with assorted mixtures, boiled quail egg). And noodles 8(cold buckwheat noodles, fried mung-beans), noodles 2(buckwheat noodles, fried vegetable), Western meals 3(hamburg steak, steamed dumpling), noodles 18(rice-cake dumping soup, fried sweet potato with sugar syrup) were preferred by the subjects. The worst preferred menu was soups 4(loach soup, fried sea food and welsh onion). In the preference each kinds of set menus, Korean meals 3(soup to relive the hangover with pollack, grilled meat, lettuce, fruit salad, Kimchi, ice tea) was the most preferred of the Koreans meals, bowel of rice 8(omelet containing fried rice, chicken salad) of the bowel of rices, noodles 8(cold buckwheat noodles, fried mung-beans) of the noodles, soups 3(spicy beef soup, chicken salad) of the soups, fried rice 5(boiled rice with assorted mixtures, boiled quail egg). There was no significant sexual difference in the menu preferences except 7 menus. There was significant age difference in the 17 menu preference, the younger age subjects were the better like noodles.
