Enzymatically hydrolyzed soy sauce(eHSS) was prepared by the treatment of defatted soy flake using two types of proteases, followed by maillard reaction and formulation with some ingredients. The eHSS was mixed with fermented soy sauce(FSS) to make enzymatically hydrolyzed mixed soy sauce(eHMSS). The properties and sensory characteristics were evaluated and compared with commercially available soy sauces. The control of salt and total nitrogen contents in eHSS and eHMSS was easy, and the production of soy sauce of low salt and high protein was possible. However, the free amino acid content of eHSS was lower than FSS. due to lower degree of hydrolysis. In sensory evaluation, the eHSS have no loss taste and overall acceptance than FSS. Consequently, the eHSS and eHMSS have the potential for use with FSS to produce high quality soy sauce of low salt and high protein contents.

Soy sauce has a long history used as a food ingredient. However, hydrolyzed vegetable protein, mono-sodium glutamate, starch syrup, and fructose are added to soy sauce during fermentation for the taste and flavor of product. But consumers have been reluctant to the taste of these artificial additives. In this experiment, anchovy sauce was used to prepare soy sauce to enhance the quality and brine was used as a control. To evaluate the quality of soy sauce added with anchovy, total nitrogen (TN) and soluble nitrogen contents, total soild contents, total sugar reducing sugar. lactic acid content and protease activity were monitored during fer-mentation. Total microbial numbers and lactic acid bacteria were not significantly changed among the cases. Aerobic and anaerobic microorganisms. and lactic acid bacteria were not significantly changed among the cases we studied, For the total sensory test, it was also estimated that the cases using anchovy sauce were superior to the control. From the results mentioned above, we could obtain shorter fermenation period as well as the quality improvement in the case of using anchovy sauce instead of salty water in the fermented soy sauce production.

This study investigated changes in the quality and antioxidant activity of soy sauce with added Saccharina japonica powder (FSP). Soy sauce was prepared with acid-hydrolyzed soy sauce, brewed soy sauce, honey, ginger, garlic, dried red pepper, ${\gamma}$-aminobutyric acid (GABA)-enriched sea tangle fermented in lactic acid, and 1% or 3% S. japonica powder by soy sauce volume. The color, pH, microbiology, amino nitrogen, free amino acids, antioxidant activity, and sensory qualities of the soy sauce were evaluated. There were no significant differences in the general characteristics or antioxidant activity. However, the addition of FSP to the soy sauce enhanced the delicate flavor. Furthermore, soy sauce containing FSP had higher levels of GABA (50 mg/100 mL), a biofunctional ingredient. Therefore, the development of seasoning soy sauce with enhanced functionality seems possible.

3-Monochloro-1, 2-propanediol(3-MCPD) was analyzed in soy sauce products commercially available in Korea. A total of 24 samples were collected and 3-MCPD was determined by GC/MS. Sources of 24 samples were classified by manufacturing methods as naturally brewed(NB), acid hydrolyzed(AH) and mixed(M=NB+AH) soy sauces. 3-MCPD was not detected in NB soy sauce products (＜ 0.01 ppm, mg/kg) whereas AH and M soy sauce products showed a wide range of 3-MCPD contamination(0.01~2.038ppm).

본 연구는 재래간장, 양조간장 및 산분해간장 등 제조방법에 따른 색도, 유리당 및 유리아마노산 함량 등의 품질특성을 비교하였다. 실험결과, 명도를 나타내는 L값의 경우, 산분해 간장 및 양조 간장이 재래 간장보다 낮은 값을 나타내었고, 재래 간장의 경우 제조 후 시간이 지날수록 L 값이 높아졌다. 또한, 재래 간장의 단맛 함량이 개량식 간장보다 비교적 높은 경향을 보였으며, 재래 간장의 경우 제조 후 시간이 지날수록 함량이 증가하는 것을 알 수 있었다. 쓴맛의 지표가 되는 아미노산 총 함량의 경우, 제조 후 시간과는 큰 차이가 없었으며 산분해 간장이 다른 간장보다 높은 함량을 나타내었다. 감칠맛과 가호성에 중요한 역할을 한다고 알려져 있는 glutamic acid의 함량은 양조 간장이 가장 높은 함량을 나타내었고, 산분해간장, 제조 2년 후 재래 간장, 제조 당해 재래 간장의 순으로 나타났다. 개량식 간장이 재래 간장보다 glutamic acid 함량이 높았으며, 재래 간장에서는 제조 후 시간이 지날수록 glutamic acid 함량이 증가하는 경향을 보였다. GABA는 재래 간장보다 개량식 간장에 더 많이 함유되어 있었고, 재래 간장의 경우 숙성기간이 길어질수록 그 함량이 증가하였다.

This study was conducted to investigate Korean soy sauces and Japanese soy sauces for their flavor and taste when they are used for Teriyaki sauce preparation. The results showed the followings; 1. The panelists liked more naturally brewed soy sauce (NBS) than mixed (NBS + acid-hydrolyzed) soy sauces, especially S company's NBS, 501S and Japanese K company's koikuchi NBS were preferred sauces. 2. The preference of Chicken Teriyaki preparation were also appeared to be the highest with S company's NBS, 501S and Japanese K company's koikuchi NBS. Both of them are naturally brewed soy sauces. 3. Chicken Teriyaki Sauce's preference were also high that made from the highly preferred soy sauces, therefore, it would be the better selection with the highly preferred soy sauces for the Chicken Teriyaki preparation. 4. There were no significant difference in preferences between imported NBS and domestic NBS, so it would be good to use Korean NBS for Chicken Teriyaki preparation.

3-Monochloro-1,2-propanediol(3-MCPD) was analyzed in soy sauce products commercially available in Korea. A total of 24 samples were collected and 3-MCPD was determined by GC/MS. Sources of 24 samples were classified by manufacturing methods as naturally brewed(NB), acid hydrolyzed (AH) and mixed (M = NB + AH) soy sauces. 3-MCPD was not detected in NB soy sauce products (< 0.01 ppm, mg/kg) whereas AH and M soy sauce products showed a wide range of 3-MCPD contamination (0.0l ∼ 2.038 ppm). The contaminated levels of 3-MCPD in soy sauce products were higher than the permissible or tentative permissible level of 3-MCPD in both European Community (0.02 ppm) and Korea (0.3 ppm). These data suggest that 3-MCPD levels contaminated in soy sauce products in Korea were shown to be too high and should be reduced to as low a level technologically feasible to protect Korean from the exposure to toxic chemical, 3-MCPD.

Alkali treatment following acidic hydrolysis (ATAH) of defatted soybean is currently used to reduce the level of 3-chloropropane-1,2-diol (3-MCPD), a known carcinogen, in commercial Korean soy sauce. 3-MCPD concentrations in commercial soy sauces made by ATAH were compared with those made only by acidic hydrolysis, and products that combine soy sauce made by acid hydrolysis (followed by alkalinization) and enzymatic methods. The four soy sauces made by ATAH had lower 3-MCPD concentrations (below 0.078 ppm) than 4 commercial products (0.147∼0.481 ppm) made only by acidic hydrolysis. On the other hand, 3-MCPD concentrations in 4 commercial products made by combining soy sauces made enzymatically with that made from acid (with alkali treatment)-hydrolyzed soybean protein in varying ratios were in a range of 0.016∼0.053 ppm. The 3-MCPD concentrations in commercial Korean soy sauces, with the exception of 2 of the soy sauces made only by acidic hydrolysis, were lower than allowable limit of 0.3 ppm in Korea. These results demonstrated that currently produced commercial soy sauces on the Korean market hate toxicologically save 3-MCPD concentrations. It is also provides evidence that ATAH is an effective process for reducing 3-MCPD concentrations in commercial soy sauce.

본 연구에서는 3-MCPD의 함량을 신뢰할 수 있는 결과값의 도출을 위하여 HFBI 유도체화 방법을 이용하였다. 3-MCPD가 검출되지 않은 양조간장에 3-MCPD를 0.020과 $0.200{\mu}g/mL$의 농도로 spiking하여 그 결과 값을 측정한 결과, 회수율이 95% 이상으로 우수하였으며 분석의 재현성 및 정밀성 또한 우수하였다. 아미노산 간장의 제조 조건 중 3-MCPD의 함량에 영향을 미칠 것으로 추정되는 조건 즉, 알칼리 처리시의 pH와 온도, 그리고 유지 시의 온도와 시간을 다양하게 하여 시료를 제조 한 후, 3-MCPD의 함량을 측정하였다. 그 결과, 알칼리 처리시의 pH와 온도가 높고, 유지 온도와 시간이 증가됨에 따라 3-MCPD의 함량이 감소되는 뚜렷한 경향을 나타내었다. 또한 알칼리 처리 온도와 유지 온도에 대한 영향보다는 알칼리 처리시의 pH가 3-MCPD의 함량에 미치는 영향이 더욱 큰 것으로 판명되었으며, 특히 pH 10.0 이상에서 알칼리 처리를 하였을 경우는 알칼리 처리 온도나 유지시간 및 유지온도 등의 다른 조건들에 상관없이 3-MCPD의 함량이 $0.020{\mu}g/g$ 이하로 현저히 낮아지는 경향을 보였다. 본 연구의 결과에 따르면 일반적인 아미노산 간장의 제조 공정 조건에 변화를 줌으로써 실질적으로 생성되는 3-MCPD의 함량을 현저하게 낮출 수 있음을 알 수 있었으며, 이러한 결과는 아미노산 간장의 3-MCPD 저감화 방안을 강구하기 위한 기초 자료로 활용할 수 있을 것으로 판단된다.
