카세트식 이동식부탄연소기의 사고는 과열에 의한 화재뿐만 아니라 접합용기의 파열에 따른 피해가 더 큰 위험성을 내포하고 있다. 접합용기의 파열원인은 화재에 의한 파열과 접합용기 장착 불량에 의한 가스누출로 화염에 의한 파열, 그리고 과대 조리기구를 사용하여 조리기구 및 화염에서 발생되는 열이 접합용기에 전달되어 온도상승에 따른 파열로 구분된다. 현재 카세트식 이동식부탄연소기의 조리기구 크기에 따라 과열에 따른 정확한 검증이 부족하며, 사용자에게 사용장소와 조리기구외 크기만 권고하고 있어 이에 대한 자료가 필요하다. (중략)

Formaldehyde and phenol used in the production of melamine-wares may be intended to come into foodstuffs. So this study investigated the migration of formaldehyde and phenol from 222 articles Articles were cups(14), bowls(75), plates(85), spoons(10), chopsticks(4), food trays(8), rice paddles(4), spatulas(9) and scoops(12). The food stimulants were 4% acetic acid, 20% ethanol, distilled water and n-heptane. Korea regulation (Standards and specifications for food utensils, containers and package) specifies migration limits for formaldehyde and phenol in food stimulants. Formaldehyde and phenol are restricted by 4 mg/L, 5 mg/L respectively. In all cases the migration of formaldehyde and phenol were below the limit set in Korea regulation. The level of formaldehyde and phenol migrated to food simulants were in the range of N.D~2.949 mg/L, N.D~0.078 mg/L respectively. These migration results of formaldehyde and phenol will provide a scientific basis for the safety management of melamine-wares.

This survey was performed to investigate the holding amount of the various kinds of cooking tools of the farm and fishing villages in Chungnam area. The results were as follows: 1. The holding ratio of refrigerators was the highest (97.9%), and that of toasters was the lowest (1.9%) among the electric tools. 2. The holding ratio of gas-ranges was the highest (95.7%) and that of gas oven-ranges was the lowest (1.2%) among 4 kinds of gas tools under investigation. 3. The holding amount of pans was the highest among the cooking tools and that of wicker baskets was very high among the small cooking tools. The holding ratios of egg-cutters and lemon-squeezers were very low (4.1% and 2.9%, respectively). 4. The holding ratios of various kinds of cooking tools were related to the housewife's educational background and family income.

The purpose of this study is to investigate textural characteristics of egg solution coagulated with steamer and microwave oven, and egg solution diluted various concentration of it with water or milk. Textural Characteristics of the samples were evaluated by the Sensory test and Rheometer. The results obstained were as follow; 1. Rheometer measurement indicated that the thicker is concentration of egg solution, the harder is samples 2. In sensory evaluation on the various concentration of egg solution, the panels on the overall quality showed the most favorite tendency that the sample diluted with 50% of water and the one with 70% of milk in use steamer; the sample diluted with 30% of water and the one with 70% of milk in use microwave oven.

This study was performed to assess the microbiological quality of kimbap (rice balls rolled in laver) prepared in two conditions (normal condition or clean, sanitized condition) and to support a practical application to identify critical control points (CCPs) in the preparation and cooking processes of kimbap. Kimbap, raw materials of kimbap, utensils (knives, cutting board, and kimbal which is made of bamboo), and hands of food handlers were examined microbiologically. Airborne microbes in the kitchens were also evaluated. Escherichia coli, Salmonella and Staphylococcus aureus were not detected in all samples. The aerobic bacteria and coliform bacteria levels of all samples in clean, sanitized condition were much lower than those in normal condition. More aerobic bacteria and coliform bacteria were counted in unheated raw materials of kimbap than in heated raw materials. In both conditions, the levels of airborne microbes of the kitchens were satisfactory. The aerobic bacteria and coliform bacteria of kimbap prepared in clean, sanitized condition were one hundredth levels of those of kimbap prepared in normal condition. However, fecal coliforms were detected even in the kimbap prepared in clean, sanitized condition. The results indicate that microbiological contamination of kimbap may be mainly originated from the contaminated unheated raw materials, utensils, and hands of food handlers, and also possible cross-contamination during preparation. The CCPs for kimbap preparation and cooking were handling of unheated raw materials, cleaning and sanitizing utensils, and hand washing of food handlers.

This survey was performed to investigate the actual holding conditions of the electric tools, gas tools and small cooking tools in the four Korean big cities; Seoul, Pusan, Kwangju and Taejon. The results were as follows; 1. Each family had more than 8 items on the average, of 24 kinds of electric tools under investigation. The holding ratio of refrigerators was the highest (99.6%), and that of dish washers was the lowest (3.4%). 2. The holding ratio of gas-ranges was the highest(92.2%) and that of gas-ovens was the lowest (2.2%) of 4 kinds of gas tools under investigation. 3. Each family had more than 45 items on the average, of 86 kinds of small cooking tools under investigation. The holdings ratios of openers and wicker baskets were very high (98.2% and 96.6%, respectively), and those of noodle tools and Shinsonros were very low (13.8% and 13.6%, respectively). 4. The holding ratios of various kinds of cooking tools had interrelations with the size of city, housewife's educational background, family income, house style, private residence, etc.

This study suggests the possibility of a product integration of cookware and eco-friendly food culture as a new product, not merely a product for exhibition purpose. In order to, in addition to that, reflect the design produced in this project to be commercialized, it can be considered to make prototype products through a separate production processes including 3D rendering, 3D mock up. After that, various product expansions can be considered through consultation with manufacturers. This study offers the cookware product design, such as steak fans, which can be applied both domestic and international markets; everyone can cook food or grill meats to suit their tastes. It is well suited to the modern food culture with advance functions that can't be found in the existing grill fans, and it can lead the cookware product trends that seeks the originality and innovation with its design which can get across in aspects of emotion and appearance.

Currently food-borne disease is being increased at outdoor food services including hotels and restaurants. Speedy and convenient practical monitoring techniques to determine hygienic conditions are needed. This study was designed to verify correlation of direct ATP (Adenosine Tri-Phosphate) examination method using ATP bioluminescence and surveillance with check-list by inspector. Hygienic status of personal hygiene (hands), kitchen utensils (knives, chopping boards, kitchen towels, cap openers, food storage containers, and blade of slice machines), facilities and equipments (refrigerator handles, worktables, and sinks) in five major hotels in Seoul were examined. The result of personal hygiene of hotels was relatively better than other inspection items (46.6 points in personal hygiene, 40.2 points in kitchen utensils, 40.3 points in facilities & equipments). In ATP inspection, kitchen utensils and facilities & equipments were relatively clean comparing with personal hands data ($40.8{\pm}6.77\;RLU/cm^2$). After correlation analysis of surveillance in hygienic status points and ATP value, all results showed negative and high correlation. The surveillance data and ATP results investigating personal hygiene, kitchen utensils and facilities & equipments were highly correlated. The ATP examination method which shows real-time identification could be considered as an appropriate method to alternate current check-list dependent safety management in food services including hotels.

In this study we investigated the elution level of lead (Pb), cadmium (Cd), arsenic (As), zinc (Zn), nickel (Ni), antimony (Sb), germanium (Ge), aluminum (Al) and hexavalent chromium (Cr⁶⁺) from 69 home-cooking utensils into a food stimulants. The results of migration testing according to the Korea standards and specifications for utensils, containers and packages showed values the allowable migrantion limits. Al was detected in all 7 utensil materials with the average concentration ranging from 0.002-5.989 mg/L. According to the migration conditions for (180℃, 30 min), the average concentration of Al in paper was 7.2 times higher than 25℃, 10 min (P<0.05). The results of migration testing at 180℃, 30 min were also below the allowable migrantion limits. When comparing with the provisional tolerable weekly intake (PTWI) of Al, the estimated weekly intakes (EWI) accounted for 0.000-0.045% for Al.
