With changing dietary trends, active research is underway to substitute rice flour for wheat flour, commonly added to various processed foods. This study aimed to explore whether Baromi2, a floury rice incorporated in the production of Sujebi, can effectively replace wheat flour at appropriate levels based on its physicochemical and cooking characteristics. Baromi2 was categorized based on particle size (100, 140, and 200 mesh) and added in proportions of 10% and 20% relative to the weight of wheat flour. As the amount of Baromi2 increased, the protein and lipid content of the mixed flour also increased. Simultaneously, the dough strength decreased as the noodles became thinner, reducing hardness, gumminess, and chewiness. Additionally, a decrease in particle size increased peak viscosity and breakdown viscosity, whereas setback viscosity decreased. When Baromi2 was added at a 10% ratio, it displayed a low cooking loss, demonstrating desirable characteristics for Sujebi and was considered the most suitable proportion for production. These results provide foundational data for developing various rice-processed products using Baromi2, contributing to expanding consumption and enhancing utility.

This study evaluated the physicochemical characteristics of wheat-flour mixed powders and cooking properties of Sujebi based on the addition of ‘Baromi2’ rice flours for increased expansion of rice consumption. The addition rates at which a roll surface sheet was formed were selected as 0, 10, 20, 30, and 50% based on preliminary experiments with 0-90% addition rates of ‘Baromi2’. Results of physicochemical characterization showed that increasing the addition ratio of ‘Baromi2’ rice flour resulted in increased crude ash and crude fat levels, however crude protein and total starch decreased. The L*-value (lightness) increased with increasing addition ratio of ‘Baromi2’ rice flour; in contrast, a*-value (redness), b*-value (yellowness), and particle size decreased. Results of RVA showed that increasing the addition ratio of ‘Baromi2’ rice flour increased the peak, breakdown, and setback. Regarding textural properties, hardness and chewiness values were significantly reduced with increasing addition ratios of ‘Baromi2’ rice flour. Based on these results, a blending ratio of 20% or less of ‘Baromi2’ is considered suitable for producing Sujebi, and this result serves as basic data for the development of processed rice flour products using ‘Baromi2’.

When cooking, especially during processes such as grilling or frying, harmful gases are generated. Among them, fine dust is a major factor causing lung cancer, and to eliminate it, range hoods are commonly used. Particularly, when using portable cooking device like gas stoves, it is even more challenging to remove fine dust. In this study, a cooking device was developed to combine steam and cooled air in the air-curtain area to recover fine dust generated during the cooking process, allowing it to be collected as food. The device was evaluated according to criteria defined independently and validated through experiments. As a result, all criteria were satisfied within the specified range.

This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.

The (Hanilseonman) New Dictionary is a multilingual dictionary of Chinese characters marked in multiple characters. It records the pronunciation and interpretation of Korean, Japanese, Northern Mandarin and Manchurian language corresponding to Chinese characters. There are few Chinese-Korean bilingual dictionaries in modern Korea, and the (Hanilseonman) New Dictionary, which records many Chinese words, is evaluated as the prototype of Chinese-Korean dictionaries. In this study, we examine the Chinese and Korean meanings of the ‘火部’ Chinese monosyllabic cooking verbs in the (Hanilseonman) New Dictionary. We then analyze their meanings, summarize their meaning-positions and classify the semantic fields. Furthermore, the accuracy of their Chinese and Korean interpretations in the (Hanilseonman) New Dictionary is examined, and the prominent interpretation methods and characteristics of the (Hanilseonman) New Dictionary are investigated. This study examines the influence of Modern Times food culture and language, and also points out the problems of Modern Times Chinese-Korean bilingual dictionaries and the direction of future dictionary compilation. This paper discussed the applicability of modern and contemporary Chinese-Korean dictionary definitions, examine the interpretation strategies of modern and contemporary Chinese-Korean dictionaries, summarize their similarities and differences. This paper also discusses the applicability of modern and contemporary Chinese-Korean dictionaries from the perspective of language learners. This study has significance for researchers on the historical development of Chinese-Korean dictionary compilation.

This study aimed to determine the changes in the vitamin B5 content of raw and cooked vegetables. The nineteen vegetables were subjected to different cooking methods, viz. blanching, boiling, pan-broiling, and steaming. Vitamin B5 was quantified by reversed-phase high-performance liquid chromatography (HPLC) using photodiode-array (PDA) detection (200 nm). The standard reference materials (SRM) were used to validate the accuracy of vitamin B5 measurement method used in this study. The cooking yields ranged from 82.63 to 107.62% and decreased in most of the vegetables except bitter melon, curled mallow, and eggplant. The raw kabocha squash, Danhobak, had the highest vitamin B5 content (0.671 mg/ 100 g) among the samples. All cooked vegetables showed lower vitamin B5 content compared to the raw samples. The true retention ranged from 0% (crown daisy, blanching) to 84.49% (kabocha squash, steaming). These results indicate that vitamin B5 is degraded after cooking. Pan-broiling and steaming are better cooking methods than the others for retaining vitamin B5. The true retention of vitamin B5 in the samples markedly depends on the cooking method and food matrix. These results can be used as important basic data for nutritional evaluation of meals.

The purpose of this study was to investigate the preparation and cooking processes used to prepare Eungi in cookbooks published from the 1700s to the 1900s. ‘Eungi’ is a thin gruel made of starch powder. Fourteen historical cookbooks were included and investigated for the preparation of ingredients and processing methods. Fourteen types of eungi were identified. Arrowroot eui and kuseonwangdogo eui were found in 『Kyuhapchongseo』 written in the early 1800s, and many types of eungi (i.e. job’s tears eungi, arrowroot eungi, sorghum eungi, lotus root eungi) were mentioned in 『Kunhakhoedeung』, but unfortunately, ingredients and cooking methods were not included. ‘Eungi’ was made by boiling starch powder prepared using the ‘subi method’, that is, dried after grinding main ingredients such as job’s tears using a millstone followed by soaking and settling. Eungi boiled with water or omija water were seasoned with the sugar or honey, and salt. These eungis were used for stomach complaints and hangovers and to promote longevity.

한중 조리동사는 의미의 범주가 달라 대응관계가 매우 복잡하다. 동일한 조리활동 을 가리키면서도 중국어와 한국어가 ‘일대일’의 대응관계를 보이지 않는 경우가 있다. 본 연구는 삶다(煮)류 의미장의 중국어 13개, 한국어 9개 조리동사를 대상으로 계열 관계와 결합관계를 통해 의미소를 설정하고 이들의 의미특징을 분석하여 한중 조리 동사의 대응관계를 살펴보는데 목적이 있다. 특히 사전과 코퍼스를 활용하여 다의어 에서 다수의 의미소를 설정하고 분석하는 방법과 과정을 제시함으로써 한중 조리동 사의 의미 범주 차이를 고찰하였다. 구체적인 의미자질 분석을 통해 중국어 조리동 사에서 다의성이 강하게 나타나고 의미의 범주가 크다는 결론을 내릴 수 있었다.

This study examines the effects of different cooking methods (stir-frying, steaming, superheated-steaming) on the contents and the true retention of moisture, water-soluble vitamins, and bioactive compounds of ten selected vegetables: broccoli, brussels sprout, cabbage, eggplant, green bean, onion, red cabbage, red onion, squash, and tomato. The total color difference (ΔE) values were decreased after stir-frying the samples, except for eggplant, green bean, and tomato. The true retention of water-soluble vitamins (B1, B2, B3, and C) was increased in most vegetables after superheated-steaming, as compared to steaming and stir-frying. Moreover, compared to the uncooked vegetables, a higher true retention of total polyphenol and flavonoid was obtained for most vegetables subsequent to superheated-steaming. Total anthocyanin content was detected only in eggplant, red cabbage, and red onion, and a smaller loss of anthocyanin was determined after subjecting red cabbage to superheated-steaming. Also, the free radical scavenging activities were higher in superheatedsteaming vegetables, except in eggplant and squash. These results indicate that superheated-steaming induces a positive effect for retaining water-soluble vitamins and functional components of vegetables.

Cooking, especially meat and fish grilling, is one of the representative sources of indoor and outdoor particulate matter (PM). Most of PM emitted from cooking is ultrafine dust (PM2.5). Since odorous organic acids, aldehydes, and volatile organic compounds are absorbed by PM and discharged, restaurants and food service industries are major sources of odorous PM emission that cause odor nuisance complaints in cities. PM emitted from cooking also contains polycyclic aromatic hydrocarbons (PAHs), which are carcinogens. In this paper, the domestic PM emission status of biomass combustion, especially meat and fish grilling, was analyzed temporally and spatially. The results of previous studies on PM emission concentrations, emission rates, emission factors and their compositions from cooking were comprehensively summarized. In addition, the effects of food ingredient types, cooking methods, seasoning and oil addition and fuel types on the PM emission were reviewed. Much more PM was produced when cooking with charcoal rather than electricity or gas. The higher the fat content of food ingredients such as intestines, the higher the PM emission concentration and emission rate. There was a difference in the PM emissions depending on the cooking oil types, and the PM emission concentration was high when olive oil or corn oil was used. It is necessary to accumulate more information through followup studies on the emission concentrations, emission factors and properties of PM emitted from cooking activities. This information can be used for controlling odorous PM in restaurants and food service industries, and predicting the impacts of odorous PM on air quality and human health.

2020년 경기도내 대형매장과 베이킹 전문매장 등에서 유통 중인 홈베이킹 조리기구 69건(폴리에틸렌테레프탈레이트(PET)제, 불소수지(FR)제, 가공셀룰로스제, 고무제, 종이제, 금속제, 유리제)을 대상으로 유해금속 9종(납, 카드 뮴, 비소, 아연, 니켈, 안티몬, 게르마늄, 6가크롬, 알루미늄)의 용출량 및 알루미늄의 식품으로의 이행량을 조사하여 홈베이킹 조리기구의 안전관리를 위한 기초자료로 활용하고자 하였다. 홈베이킹에서 사용되는 69건의 조리기구는 식품용 기구 및 용기·포장 공전의 용출규격 기준에 모두 적합하였다. 금속제의 니켈이 최대 0.009 mg/L 검출 되었으나 기준에 적합하였고 이외 유해금속은 불검출이었다. 규격 기준 이외의 금속에서 주로 용출된 유해금속은 알루미늄으로 7개의 재질에서 모두 용출되었으며, 4% 초산으로 용출된 종이제(1.417 mg/L)와 가공셀룰로스제 (5.069 mg/L)에서 높은 용출량을 보였다. 홈베이킹에서 주로 사용되는 조리조건인 180˚C, 30분 용출실험 결과, 식품용 기구 및 용기·포장 공전에 따른 용출실험 대비, 종이제의 알루미늄의 용출량이 7.2배 유의하게 증가하였다 (P<0.05). 이외 납 등 다른 유해금속이 추가로 검출되었다. 180˚C, 30분으로 용출온도가 증가하여도 식품용 기구 및 용기·포장 공전의 용출규격 기준에는 모두 적합하였다. 알루미늄의 위해도 평가결과, 종이제 > 금속제 > FR제 > 고무제 및 유리제 > PET제 및 가공셀룰로스제 순으로 나타났으며, 전체 위해도는 0.000-0.045% 수준으로 국민생활 건강에 위해를 끼치지 않는 안전한 수준으로 확인되었다. 홈베이킹 조리기구의 용출량 조사결과, 유해금속은 안전하게 관리되고 있는 것을 확인하였고, 본 연구의 결과는 향후 식품용 기구 및 용기·포장의 안전관리를 위한 과학적인 근거자료로 활용될 수 있을 것으로 사료된다.
