본 연구는 상품화된 육수 재료의 이용 현황 및 소비자 의견을 조사하기 위하여 수행되었고 이를 위해 서울에 거주하는 500명의 주부를 대상으로 설문조사를 실시하였다. 그 결과, 사용하는 제품의 종류는 분말형이 가장 많았고 시간 절약과 편리함이 상품화된 육수재료를 사용하는 가장 주된 이유였다. 또한 육수 재료를 사용하는 방법으로는 육류로 만든 육수에 섞어서 사용하는 방법이 가장 많이 쓰이고 있었다. 상품화된 육수 재료의 기호도에 대해서는 응답자의 81%가 상품화된 육수에 대해 '좋아하지 않는다'라고 하였다. 좋아하지 않는 가장 큰 이유는 '첨가제에 대한 염려와 인공조미료 때문'이었다. 연령이 높고 결혼지속년수가 길수록 상품화된 육수 재료를 좋아하지 않는 비율은 높아졌다. 상품화된 육수가 품질만 보장된다면 응답자의 75%는 사용할 의사가 있는 것으로 나타났으나 나머지는 아무리 좋은 품질이라 해도 육수는 직접 제조하겠다고 응답하였다. 60대 이상의 응답자들만은 상품화된 육수를 사용하지 않겠다는 비율이 더 높아 60대 이상의 고령층은 상품화된 육수 제품에 대해 가장 거부감이 큰 연령대인 것으로 판단된다. 본 연구 결과, 상품화된 육수의 수요는 크나 시판되는 제품들에 대한 만족도는 낮은 것으로 나타났으므로 소비자 요구를 반영한 육수 제품에 대한 연구가 시급한 것으로 생각된다.

Food waste in school foodservices is an important factors in managing expense and in evaluating the acceptance of served meals. This study was undertaken to investigate the management of food waste and the opinion of dietitians in one hundred fourty nine elementary school foodservices, in Pusan, Korea. When serving places were compared, the classroom generated more leftover and plate waste than those of lunchroom(p<0.05). In rank for generating raw waste, the residue from vegetables was the highest in first order. Fruit, eggs, fish, and shell fish also left the most raw waste, respectively, in descending order. The residue that generated the most plate waste in the first and the second order was from soup and pot stew, and vegatables side dishes, respectively. The treatment process of food waste which was the most common in school foodservices was the fertilization by processing machine in order to make recyclable fertilizer(52.1%). Food waste at 30.8% of foodservices was processed for live stock feed. At 92.3% of investigated foodservices, food waste water was drained through a round net basket. Before treating as a waste, food residue was recycled at only 41.9% of foodservices. The main utilization of food residue was the production of soap from used oil. Most dietitians in school foodservices recognized that treating food waste was not so inconvenient, although, the problems of odor and hygiene were not solved. They also thought that the liquid residue(54.1%) and oil(30.4%) among food waste were primarily responsible for resulting environmental pollution.

This study was aimed to develop short necked clam stock, which is the base of sauce, soup, etc., using various nourishing elements in short necked clams. In short necked clam stock with different heating times, the moisture content was significantly different (p < 0.05). For the color value of short necked clam stock, L value was the highest in S1(31.15), while the highest a value was found in S5(-0.36) and the highest b value in S5(0.67). pH was the lowest as 7.35 in S5. When heating time increased, pH decreased significantly (p < 0.001). The sugar content was the highest as $3.30^{\circ}Brix$ in S5 and the lowest as $2.63^{\circ}Brix$ in S1. The salinity content was the lowest as 0.73% in S1, and it increased significantly(p < 0.001) with increased heating time. Na was the highest among the mineral contents and the highest K, Mg, Ca, Fe contents were found in S5 heated for 60 mins. Twenty one kinds of free amino acid were detected in short necked clams. The highest essential amino acid content was arginine, the highest flavor enhancing free amino acid was glycine, and the highest derivative amino acid was taurine. The test for characteristic differences of short necked clam stock showed that savory taste and savory flavor of S4 heated for 50 mins were the highest. According to the results of acceptance test, S3 showed the best results. In conclusion, short necked clam stock showed great preference with increased heating time, and the preference has increased when it was simmered for 35~40 mins.

An assortment of daily supplies have been documented in and accounting book that Hwa-sun Song, a wholesale dealer in Hongcheon, Gangwon-do, sent to Young-hui Sin, a customer. This study analyzed a total of 163 documentations in the accounting book between 1910 to 1916, which includes types of daly supplies, trading volume, and prices, maintained accounting between. Consequently, we are able to indentify companies that produced the applicable goods, names of products, units by which goods were counted, and the lowest and highest prices prevailing, along with kinds of goods patronized in everyday life in Hongcheon in the early 20th century. Paper had the maximum trading volume. The second, most traded were cigarettes, a symbol of the new culture. These were traded under various brand names, such as Kkotpyo, Guksyu, Sanhopyo, Syonghak, and Joil. Foodstuffs, were the third most traded items, including fish, fruits, sugar, Waeddeok, Chilwaeddeok, Color candies and Okchyun candies. Our results indicate that the snack food business had developed since the 19th century. Lighting equipment, oil, candles, matches as well as traditional oil lamps and flints cornered the fourth largest stock being traded. Medications were fifth, with prescriptions written for Insohwan, Hoechyungsan and Siungo, including quinine, a medicine for malaria. Other trades included kitchen appliances such as soup bowls, porcelain bowls, kettles, and drinking cups, and a variety of daily supplies such as mirrors, mats, umbrellas, Geumjiwaemil, hair oil imported from Japan, and soap.

This study was carried out to prepare powdered smoked-dried mackerel which can be used as a soup base, and to examine storage stability and the taste compounds of Products. Raw mackerel are filleted, toiled for 10 minutes and pressed to remove lipids, and then soaked in extract solution of skipjack meat. This soaked mackerel are smoked 3 times to $10-12\%$ moisture content at $80^{\circ}C$ for 8 hours. And the smoked-dried mackerel were pulverized to 50 mesh. Finally, the powdered smoked-dried mackerel were packed in a laminated film $bag(PET/Al\;foil/CPP:\;5{\mu}m/15{\mu}m/70{\mu}m,\;15\times17cm)$ with air(product C), nitrogen(product N) and oxygen absorber(product O), and then stored at room temperature for 100 days. The moisture and crude lipid content of powdered smoked-dried mackerel was $11.3-12.3\%,\;12\%$, respectively, and water activity is 0.52-0.56. And these values showed little changes during storage. The pH, VBN and amino nitrogen content increased slowly during storage. Hydrophilic and lipophilic brown pigment formation showed a tendency of increase in product(C) and showed little change in product(N) and (O). The TBA value, peroxide value and carbonyl value of product(N) and (O) were lower than those of product (C). The major fatty acids of products were 16:0, 18:1, 22:6, 18:0 and 20:5, and polyenoic acids decreased, while saturated and monoenoic acids increased during processing and storage of products. The IMP content in products were 420.2-454.2 mg/100 g and decreased slightly with storage period. And major non-volatile organic acids in products were lactic acid, succinic acid and $\alpha-ketoglutaric$ acid. In free amino acids and related compounds, major ones are histidine, alanine, hydroxyproline, lysine, glutamic acid and anserine, which occupied $80.8\%$ of total free amino acids. The taste compounds of powdered smoked-dried mackerel were free amino acids and related compounds (1,279.4 mg/100 g), non-volatile organic acids(948.1 mg/100 g), nucleotides and their related compounds (672.8 mg/100 g), total creatinine(430.4 ntg/100 g), tetaine(86.6 mg/100 g) and small amount of TMAO. The extraction condition of powdered smoked-dried mackerel in preparing soup stock is appropriate at $100^{\circ}C$ for 1 minute. Judging from the results of taste and sensory evaluation, it is concluded that the powdered smoked-dried mackerel can be used as natural flavoring substance in preparing soups and broth.

A study on sliced raw fish consumption was conducted on 300 citizens of Busan (89 men and 192 women), attending high school and university, housekeepers and employees. A self-administered questionnaire was used to record the results. The results were as follows: 93 percent of the respondents appeared to like or not be reluctant to eating Maeun-Tang. Most of the panelists had eaten at a seafood restaurant. The taste of Maeun-Tang varied differently by the spicy fish soup recipe. 56 percent of the respondents appeared to want this dish to have a fiery taste. Therefore, 89 percent of the respondents appeared to desire Maun-Tang to have a standardized recipe. The qualities of four kinds of stock made of water (A recipe), anchovy added with sea tangle (B recipe), fish bone (C recipe) and vegetable (D recipe) were investigated by using sensory evaluation and instrumental analysis for amino acids and nucleotides. The C recipe score was 80.9${\pm}$15.9 and D, B recipe was $75.7{\pm}17.1$, $75.4{\pm}17.2$, respectively. The A recipe score was $61.8{\pm}22.8$. The Degree of smooth taste were D recipe >A recipe >B recipe>C recipe. The Degree of spicy taste were C recipe >B recipe >D recipe>A recipe. In sensory evaluation, the C recipe obtained the highest score for overall preference. However, no difference of extractive nitrogen content, nucleotide and amino acid contest were observed in the C recipe after cook of Maeun-Tang.
