  • 액젓중의 ATP 관련물질의 정확한 분석방법을 확립하기 위하여 현재 사용되고 있는 HPLC법과 새로운 분석방법인 효소법을 비교$\cdot$검토한 결과는 다음과 같다. 1. HPLC 분석법에 의한 멸치 및 까나리육중의 ATP 관련물질총량은 각각 9.332$\mu$mo1/g 및 9.468$\mu$mo1/g이었고, 멸치 및 까나리 액젓중의 ATP 관련물질총량은 각각 3.989$\mu$mol/g 및 4.145$\mu$mol/g 으로 원료육의 $42.7\%$$43.8\%$였다. 그리고, Hx량은 ATP 관련물질총량의 $85\%$ 정도를 차지하였다. HPLC 법으로 ATP 관련물질을 분석시에 식염의 영향은, 식염농도가 $2.5\%$일 때, IMP, HxR 및 Hx 표준물질의 검출율은 $83.8\~86.4\%$였다. 그리고, IMP, HxR 및 Hx는 254nm에서, 그리고 uric acid는 290nm의 파장에서만 검출되었다. 2. 효소법으로 ATP관련물질 분석시에는 IMP, HxR 및 Hx 표준물질의 검출율이 거의 100\%$였으며, 식염의 영향은 없었다. 멸치 및 까나리 액젓중의 ATP 관련물질총량은 각각 8.942$\mu$mol/g 및 9.424$\mu$mol/g으로, 원료 멸치육 및 까나리육보다 약간 적었다. 효소법으로 분석한 멸치 및 까나리 액젓중의 요산량은 각각 4.357$\mu$mol/g 및 4.632$\mu$mol/으로, 총ATP관련물질의 $48.7\%$$49.2\%$를 차지하였다. 3. 이상의 결과로부터, 액젓중의 ATP 관련물질을 분석시에는 HPLC 법이 적당하지 못하며, ATP 관련물질을 이들 분해효소를 사용하여 인위적으로 요산으로 전부 분해시켜 측정하는 효소법으로 분석해야할 것이다.

  • To develop a value-added anchovy Engraulis japonicus sauce, the processing conditions and quality characteristics of a rapidly fermented and high-purity anchovy sauce (RRAS) were examined by adding 5-10% (w/w) radish Raphanus sativus L. RRAS exhibited higher yield, total nitrogen content, and amino nitrogen and calcium contents as well as lower salinity than those of conventional anchovy sauce (control). The salinity, yield, and total amino acid contents of RRAS and control were 17.2-17.7% and 19.6%, 81.2-88.7% and 61.0%, and 13,117.8-14,174.9 mg/100 g and 10,041.1 mg/100 g, respectively. The major amino acids recorded were aspartic acid, glutamic acid, alanine, valine, isoleucine, leucine, phenylalanine, ornithine, lysine, and histidine. The histamine contents of RRAS and control were 8.3-8.6 mg/100 g and 19.2 mg/100 g, respectively, while the protease activity levels were 0.901-0.958 unit/mg and 0.695 unit/mg, respectively. Overall, this study establishes that RRAS can not only significantly shorten the salt fermentation period, but can also serve as an anchovy sauce with superior nutritional quality and higher levels of amino acid and calcium.

  • The number of covered carts selling snack foods along the streets are increasing in Korea and people enjoy eating foods at these carts. However there are only a few reports on the contamination or sanitary condition of the food carts. This study was performed to investigate the sanitary condition of food and water at the street food carts in the eight major areas of a city. Water and several kinds of food, kimbop(laver rollers) ddeokbokki(stir fried rice cake in hot pepper paste) oemuk(fish cakes) fish cake soup, and soy sauce were collected from four street carts from each of the 8 areas from June to August in 2001 The standard plate counts(SPCs) and coliform groups were examined according to the Food Code of Korea. The nufitness rates of SPCs of the samples were 0~15.6%: 15.6% in kimbop:6.3% in fish cake soup; and 3.1% in water samples SPCs were not detected in some samples. of ddeokbokki, oemuk and soy sauce. The unfitness rates of coliform groups were 0~62.5%; 46.9% in kimbop; 6.3% in ddeokbokki,;22.9% in oemuk 62.5% in fish cake soup; and 3.1% in soy sauce. Coliform groups were not detected in water sample The numbers and unfitness rates of SPCs and coliform groups showed increasing tendencies over time within a day. The higher the air temperature was the more increase of bacteriological growth was observed These results indicate that the level of bacteriological contamination of foods and water in the street carts should be monitored and strict inspection is necessary. There should be legal consequences for serving contaminated food to the public.

  • To develop a value-added anchovy Engraulis japonicus sauce, we examined processing conditions and quality characteristics of rapidly fermented, high purity anchovy sauce (RPAS) by adding 30% (w/w) intermediate salt-fermented anchovy material. RPAS had higher total nitrogen and amino nitrogen contents, and lower salinity than traditional anchovy sauce (TAS). The total amino acid contents of RPAS and TAS were 17,626.8 and 12,808.2 mg/100 g, respectively, and the major amino acids were alanine, glutamic acid, lysine, cystine, valine, and leucine. The histamine contents of RPAS and TAS were 12.6 and 25.2 mg/100 g, respectively, and the protease activity levels were 0.851 and 0.595 unit/mg, respectively. These results demonstrate that RPAS was more flavorful, and could shorten the salt-fermentation period by more than half compared to TAS, and can serve as a high-end fish sauce.

  • The historical background of fish fermentation in Asia and other regions of the world is reviewed. The classification of fermented fish products in different regions is attempted with respect to the technology involved. The fermented fish products are largely divided into three groups; (1) high-salt, (2) low-salt, and (3) non-salt fermented. High-salt fermented products contain over 20% of salt and are represented by fish sauce, cured fish and fish paste. Low-salt fermented products contain 6-18% salt and are subdivided into lactic fermented products with added carbohydrate and acid pickling associated with low temperature. Non-salt fermented products are represented by the solid state bonito fermentation and some alkaline fermentation of flat fishes. The local names of the products in different regions are compared and classified accordingly. The microbial and biochemical changes during fish fermentation are considered in relation to the quality of the products, and their wholesomeness is reviewed.

  • There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in ${\ulcorner}$Sangayorock${\lrcorner}$, two in ${\ulcorner}$Sasichanyo${\lrcorner}$, one in ${\ulcorner}$Yongjechongwha${\lrcorner}$, nine in ${\ulcorner}$Soowonjabbang${\lrcorner}$, one in ${\ulcorner}$Domoondaejak${\lrcorner}$, six in ${\ulcorner}$Dongyoebogam${\lrcorner}$, four in ${\ulcorner}$Gushangchalyo${\lrcorner}$, five in ${\ulcorner}$Guhwangboyubang${\lrcorner}$, two in ${\ulcorner}$Yorock${\lrcorner}$, four in ${\ulcorner}$Chisengyoram${\lrcorner}$ and five in ${\ulcorner}$Joobangmoon${\lrcorner}$. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

  • This study examined ways to improve the functional properties of commercial soy sauce using gelatin hydrolysates from the refiner discharge of Alaska pollock, Theragra chalcogramma. The total nitrogen content and pH of gelatin sauce prepared by dissolving the second-step gelatin hydrolysates (15 g), salt (20 g), sugar (5 g), glucose (2.5 g), inosine monophosphate (IMP) (0.5 g), black pepper (0.1 g), caramel powder (0.1 g), ginger powder (0.05 g), garlic powder (0.05 g), vinegar (3 mL), and fructose (3 mL) in water(100 mL) were 1.71% and 5.35, respectively. The results of a sensory evaluation indicated that when preparing blended soy sauce, the optimal blending ratio of gelatin sauce to commercial soy sauce was 20:80 (v/v). Because the total nitrogen content and pH of the blended soy sauce were 1.52% and 5.31, respectively, the blended soy sauce could be sold as a soy sauce. The oxidative property of the blended soy sauce was similar to that of 20 mM ascorbic acid, and its angiotensin-converting enzyme (ACE) -inhibiting activity was 1.5 mg/mL. The results suggest that the antioxidative and ACE-inhibiting activities of commercial soy sauce can be improved by blending gelatin sauce (20) with commercial soy sauce (80). The total amino acid content of the blended soy sauce was 9,107.3 mg/mL, which was higher than that (8,992.4 mg/100 mL) of commercial soy sauce. However, the taste value of the blended soy sauce was 415.8, which was lower than that (431.2) of commercial soy sauce.
