  • The school catering service has gained national attentions and has been expanding unto high schools after offering meals at elementary schools over years. This study is to identify problems and solutions in kitchen hardware areas to provide nutritiously balanced meals to schoolchildren through establishing standard menu planning. The survey analysis shows that 59.2% of dishes except for rice, Kimchi and soup are prepared by oil deep-fired or oil pan broiled. This indicates that school meals are so limited to serve baked or steamed dishes. Main reasons on the limited menu selection is that schools don't have equipment to prepare baking and steaming dishes mainly due to budget issues. All the dietitians who answered the surveys have been requesting to purchase Convotherm Ovens. Improvement solutions to the problems are: Publish the Revised Standard Equipment Layout that may allow to serve baked and steamed dishes. Establish Budget Support Program from the Government.

  • Deep-fat frying is a common cooking practice. There has been considerable concern regarding the mutagenic and carcinogenic potential of thermally oxidized oils. Studies on deep-fried foods so far have revealed not much on the mutagenicity of the oils in the foods. Therefore, in the present study, it was attempted to investigate the mutagenicity ofthe thermally oxidized safflower oil. Oil was heated in a home-fryer at a temperature of 180$\pm$3$^{\circ}C$ for 48 hours. Oil samples were taken at 0, 8, 16, 24, 32, 40 and 48 hours of heating, respectively. Each sample was used to study the changes in peroxide value (POV), acid value (AV), iodine value (IV), conjugated dienoic acid (CDA) content, %, and fatty acid composition. Another series of samples were fractionated into non-polar and polar fractions by column chromatography. The mutagenicity of the samples taken from the thermally oxidized oils, as well as the non-polar and polar fractions of the thermally oxidized oils, was investigated with the Ames test. The Ames test was carried out with and without metabolic activation. Bacterial tester strains used in the present study were the histidine auxotrophic strains of Salmonella typhimurium TA100, TA1535 and TA102 were used for the detection of base pair mutations, and TA98 and TA1537 for frame shift mutations. Each series of samples was dissolved in tetraphydrofuran (inhibitor-free) and tested at doses ranging from 0.05 to 5 mg/plate. None of the oil samples taken during the 48 hour oxidation period showed any mugagenic activity. This was the case, even after the activaton with 59 mix. Also, none of the polar and non-polar fractions showed any mutagenic activity on all the strains tested.

  • 시중에 유통되고 있는 33종류의 식용유지를 대상으로 하여 benzo[$\alpha$]pyrene의 함량을 모니터링한 결과 압착올리브유 0.5-1.4 $\mu$g/kg, 혼합올리브유 0.6-1.0 $\mu$g/kg, 참기름 0.9-1.3 $\mu$g/kg, 대두유 0.6-3.3 $\mu$g/kg, 옥수수유 0.5-1.1 $\mu$g/kg, 해바라기유 1.2, 1.7 $\mu$g/kg, 홍화유 1.0, 2.1 $\mu$g/kg, 유지가공품 1.0, 1.4 $\mu$g/kg 수준으로 검출되었다. 대부분의 시료에는 benzo[$\alpha$]pyrene 기준치인 2.0 $\mu$g/kg를 초과하지 않았지만, 미국산 대두유와 미국산 홍화유에서 각각 3.3 $\mu$g/kg, 2.1 $\mu$g/kg로 두 종류에서 기준치 이상 검출되었다. Benzo[$\alpha$]pyrene은 식용유지로 제조되기 이전에 원재료가 오염되었거나, 가공공정, 환경으로부터 노출되는 등 노출경로는 다양하다. 정제과정인 deodorizing 과정이나, bleaching 과정에 의해서 benzo[$\alpha$]pyrene의 함량이 감소되며, 압착올리브유와 혼합올리브유의 실험결과에서 정제올리브유가 혼합되어 있는 혼합올리브유의 benzo[$\alpha$]pyrene의 함량이 낮게 나타났음을 확인할 수 있었다. Benzo[$\alpha$]pyrene의 함량은 연기성분에서도 영향을 받을 수 있으므로 원재료를 건조시키거나, 볶는 과정에서 밀폐된 상태로 진행하는 것보다 개방된 상태에서 진행하는 것이 benzo[$\alpha$]pyrene의 생성을 억제할 수 있을 것으로 판단된다.

  • The effects of pork back fat (PBF) substitution with various concentrations of rice bran oil (RBO) (50%, 45%, 40% and 35%) on the physicochemical characteristics and sensory attributes of emulsion-type pork sausages were studied. The modified pork sausages were compared with control sausages produced using PBF only. The sausages with RBO had significantly lower (p<0.05) moisture content than the control sausages. Sausages made from PBF substituted with 40% RBO showed the lowest cooking loss. Substitution of PBF with RBO had no significant effect on the emulsion stability of pork sausages. All sausages with RBO showed significantly lower (p<0.05) hardness values than control sausages. Sausages with RBO also had significantly higher values (p<0.05) of unsaturated fatty acid and polyunsaturated to saturated fatty acid contents than the controls. RBO substitution had no effect on the flavor intensity of sausages, but it improved the tenderness and produced a softer texture.

  • The changes in ingredients, seasonings and cooking methods of Japchae in Korean cook books published from the 1600s to the 1960s were investigated in this study. Japchae was a royal dish enjoyed by Kwanhaegun of Joseon Dynasty and interesting historical story is contained in it. Kwanghaegun Ilgi in 1608 showed that Japchae was Kwanghaegun's favorite dish. Therefore, it has been thought that Japchae was created in the 17th century. Wonhaengeulmyojeongrieugye in 1796 described bellflower Japchae and mungbean sprout Japchae. The traditional Japchae was made without glass noodle called dangmyeon. Eumsikdimibang in 1670 first introduced traditional Japchae, which was made with 20 different ingredients and then served with topping sauce made of pheasant broth, strained soybean paste and wheat flour. Japchae in Kyugonyoram(1896) was prepared by mixing mungbean sprout, watercress, gonjasoni, tripe and yukhwe with mustard. The current style Japchae with glass noodle first appeared in the 1920s and became popular in the 1950s because the traditional Japchae was described in cook books until the 1940s. There were two ways of preparing current style Japchae. Yijogungjeongyoritonggo in 1957 described Japchae was made by mixing the boiled glass noodle with other ingredients and seasonings together. On the other hand, Japchae in Urinaraeumsikmandeuneunbeob(1960) was prepared by seasoning first with other ingredients, and then mixing boiled glass noodle. A variety of ingredients - vegetables, mushrooms, meat, fish, pheasant, beef tong, sea cucumber, gonjasoni and pear - has been used to prepare Japchae. Japchae has been seasoned with ginger, soy sauce, black pepper, sesame salt, sesame oil, oil, leek, garlic, salt, sugar, vinegar and mustard. Egg strips, pine nut, thin strips of Shiitake and stone mushroom, red pepper threads, Chinese pepper(cheoncho), black pepper and ginger were used for garnishing.

  • Purpose: In the past, laymen or beauty parlor employees commonly injected people with unproven foreign material such as paraffin, silicone, and cooking oil. We have treated a patient who injected foreign material into her face and neck. Methods: For the last 20 years, a 43-year-old woman has been injecting herself in the face and neck with foreign material. There was no tenderness, erythema, pain, ulceration, or necrosis. However many visible, touchable subcutaneous masses were found. Her face was extremely ugly and disfigured by the foreign material. We could not recognize the boundary between her neck and mandible. The occipital scalp drooped extremely. Over the past 3 years, from February 2005 to October 2007, we performed 15 operations. Results: We conducted a cephalometric facial analysis to compare preoperative and postoperative facial diameter. The patient's upper face diameter decreased from 67 cm to 60 cm, the mid face diameter from 82 cm to 59 cm, the lower face diameter from 63 cm to 50 cm, and the neck circumference diameter from 53 cm to 44 cm, respectively. The mid sagittal diameter decreased from 26 cm to 23 cm. The total excised tissue weight was 4023.7 gram after 15 operations. Conclusion: Serial excision of face and neck masses in a patient who injected herself with foreign material resulted in a satisfactory outcome.
