  • The objectives of this review are to be aware of the differences between the smear-ripened and mold-ripened cheeses and to compare the sensory attributes of smear-ripened and blue-vein cheeses. Sensory attributes of cheese occupy a prominent place for the desirable overall quality of smear-ripened and blue-vein cheeses. Smear-ripened cheeses characterized by a smooth and brittle texture. Furthermore, smear-ripened cheeses have common grittiness characteristics, also slightly salty and sour flavor compared to blue-vein cheeses. Blue-vein cheeses are characterized by a softer, creamy texture and stronger smells when goat milk is used. Blue-vein cheeses have a fresh, clean, somewhat salty and acid with a slightly bitter tastes compared to smear-ripened cheeses. Finally, the differences in sensory attributes of smear-ripened and blue-vein cheeses such as texture, aroma, and flavor, can make them useful to determine the quality of cheeses.

  • This study was carried out to examine the quality characteristics of soybean pastes made of Meju with mold-producing pretense isolated from traditional Meju. The changes in moisture content, enzyme activity (amylase, protease, lipase), reducing sugar, amino-type nitrogen contents and anti-oxidant activity were investigated during the aging period. The moisture contents decreased gradually with time. Amylase activity decreased during the aging period while pretense and lipase activities increased until 30-45 days of aging, but decreased thereafter, Especially pretense activity in soybean paste with mold was greater than that in the control. Amino-type nitrogen and ammoniacal nitrogen contents increased, but reducing sugar contents decreased with time. Amino-type nitrogen contents were greater in soybean paste made of Meju with isolated mold than those in the control. Antioxidative activity was also confirmed in soybean paste.

  • Changes in microflora and enzyme activities of three kinds of kochujang were investigated during 6 months of fermentation. Three different kinds of kochujang were prepared using Aspergillus oryzae, Aspergillus oryzae plus Bacillus licheniformis and Aspergillus oryzae, Bacillus licheniformis plus Saccharomyces rouxii. The pH of kochujang showed a slight decrease during fermentation. The number of mold and bacteria increased up to 30 days of fermentation and then decreased rapidly thereafter and the numbers of yeast increased after 30 days of fermentation. The viable cell counts of anaerobic bacteria increased remarkably up to 30 days of fermentation and then decreased to 60 days of fermentation. The activities of ${\alpha}-$, ${\beta}-\;amylase$ and protease were the highest in kochujang prepared with Aspergillus oryzae plus Bacillus licheniformis.

  • This study investigated the quality characteristics and sensory evaluation of Doenjang samples made of soybean koji and prepared with Bacillus subtillus 3-B-1 and/or Aspergillus oryzae 6-M-1 isolated from traditional Meju, to replace the koji with wheat flour. Among the quality characteristics of doenjang during its fermentation at $30^{\circ}C$ for 40 days, its moisture decreased by degrees, but its amino-type nitrogen and reducing sugar increased by degrees. The color of the doenjang made of koji and prepared with Aspergillus oryzae 6-M-1 changed more significantly than that of the doenjang with Bacillus subtilis 3-B-1. The viable cell and mold counts increased by degrees during the fermentation. The results of the sensory evaluation of the doenjang made with koji and prepared with Aspergillus oryzae 6-M-1 did not significantly differ from those of the doenjang with Bacillus subtilis 3-B-1 and of the commercial doenjang. These results showed the possibility of preparing doenjang with soybean koji instead of wheat flour koji.

  • The antifungal activity against cheese fungi by lactic acid bacteria isolated from kimchi was investigated. Eight fungi were isolated from cheese in the cheese ripening room. Two of them were identified as Penicillium and Cladosporium via ITS-5.8S rDNA analysis. Twenty-two species of lactic acid bacteria with antifungal activity were isolated from kimchi. Two of them were identified as Lactobacillus and Pediococcus via 16S rRNA sequence analysis. Of the 22 lactic acid bacteria species, six were selected (L. sakei subsp. ALJ011, L. sakei subsp. ALI033, L. sakei subsp. ALGy039, P. pentosaceus ALJ015, P. pentosaceus ALJ024 and P. pentosaceus ALJ026) due to their higher activity against the eight fungi isolated from cheese in the cheese ripening room; and among the six species, the P. pentosaceus ALJ015 and P. pentosaceus ALJ024 isolates from the Jeonju area kimchi and the L. sakei subsp. ALI033 isolate from the Iimsil area kimchi had higher antifungal activity than the other lactic acid bacteria. The minimum inhibitory concentration (MIC) of L. sakei subsp. ALI033 against the eight fungi isolated from cheese in the cheese ripening room was $62.5{\mu}g/mL$.

  • Imitated cheese was prepared from whole milk powder and fermented milk and the moisture content, general components, noncasein nitrogen, nonprotein nitrogen and free amino acids were analyzed to determine the optimal ripening conditions needed to produce imitated cheese that was similar to natural cheese. The moisture content of the imitated cheese was 40.27% one day after being produced. The cheese was ripened using two different methods; at $12^{\circ}C$ with vacuum sealing and at $12^{\circ}C$ and 95% RH with a spray of Penicillium camemberti. The lactose content decreased rapidly from 24.64 to 5.43% at the $4^{th}$ wk of ripening when it was ripened with Penicillium camemberti. The degradation of protein by mold ripening in the imitated cheese was more rapid than that of vacuum sealing. The flavor and body texture were optimal at the $4^{th}$ wk ripening. The noncasein nitrogen and nonprotein nitrogen content increased from 28.10 to 54.05, and from 6.58 to 23.06 mg/mL, respectively, when ripened with P. camemberti. When the cheese was ripened at $12^{\circ}C$, 95% R.H with P. camemberti after 4 wks, all free amino acids increased significantly except asparagines. The total free amino acid and bitter amino acid concentrations increased from 8.40 to 34.87, and from 1.53 to 10.02 nmol/mg, respectively. When the imitated cheese was prepared, the protein degradation and flavor of the cheese was better when ripened with P. camemberti.

  • 고추장의 품질을 향상시키고 재래식 전통 고추장과 유사한 맛을 지닌 고추장을 만들기 위해 재래식 전통 고추장에서 분리한 B.licheniformis 균주와 공장에서 대량 생산을 위해 개량해온 A. oryzae와, 비교적 호염성이며 알콜 발효 능력이 우수한 S.rouxii를 혼용하여 고추장을 담근 후 180일까지의 각 고추장의 이화학적 특성 변화를 조사한 결과는 다음과 같다. 단도는 모든 구에서 숙성 30일 까지 급격히 증가한 후 180일까지 거의 일정한 수준을 유지하였으며, 곰팡이 단용구에 비해 고초균과 효모 혼용구에서 숙성 기간 동안 높은 적정산도 값을 보였다. 조단백질은 숙성 기간 동안 대조구에서는 숙성 60일까지 약간 증가한 후 숙성 120일까지 급격히 감소하였으며 고초균 혼용구와 효모 첨가구는 숙성 90일 이후 감소한 후 숙성 120일 이후부터는 거의 변화가 없었다. 숙성 90일 이후부터는 B. licheniformis와 효모 혼용구에서 A. oryzae 단용구보다 조단백질 함량이 높았다. 환원당은 세 구간 모두 숙성 60일 경까지는 증가하는 추세를 보였으며, A. oryzae 단용구보다 B.licheniformis 균주와의 혼용구에서 높은 수치를 보여주었다. 비휘발성 유기산은 숙성 기간이 경과하면서 증가하였고 가장 많이 검출된 유기산은 pyroglutamic acid와 citric acid의 순이었다. 따라서 고추장의 숙성 과정 중 이화학적 특성 변화의 측면에서 볼 때 고초균과 효모 혼용구로 제조된 고추장이 구수한 맛의 생성면에서 유용한 담금법인 것으로 사료된다.

  • 피클(pickles)은 구미 각국에서 널리 애용되는 침채류이다. 수확한 농산물의 신선도를 유지하면서 장기보관 하기 위해 만들어진 것으로 여러 가지 방법이 시도되어 왔고, 동양에서는 높은 습도로 인한 곰팡이 증식을 억제하기 위하여 소금 절임 방법이 발달되었으며, 건조한 기후의 유럽에서는 세균번식을 억제하기 위하여 식초절임이 발달하였다. 피클이란 채소 또는 과실류를 소금, 식초 또는 여기에 향신료 등을 넣은 것에 절인 것을 총칭하는 것으로, 주로 오이, 컬리플라워, 양파, 미숙 토마토 등을 원료로 사용한다. 본 연구에서는 피클의 특징인 아삭아삭함을 유지하면서, 피클의 신맛과 한국 전통식장아찌를 혼용한 염장피클로, 기능적 특성을 가진 허브를 첨가하여 현대인에게 오는 성인병의 예방과 기능성 식품에 부가 가치를 높이고자 하며, 또한 피클 제조를 위한 고추의 품종 선정을 위한 기초 실험을 하고자 함에 있다. 풋고추, 청양고추, 꽈리고추 등 품종을 달리하여 제조한 고추피클의 숙성기간 중 품질특성을 실험하였다. 염도변화는 모든 품종에서 숙성기간이 길어질수록 염도가 낮아졌으며, 숙성이 완료되는 시점인 25일경에는 풋고추 2.95%, 청양고추 2.68%의 염도 변화를 보였다. pH변화는 세 품종간에 차이는 없는 것으로 보여졌으며, 숙성기간에 따른 차이도 거의 없는 것으로 나타났다. 고형분함량은 풋고추와 꽈리고추가 비슷한 경향을 보였고, 청양고추가 다소 높았다. 적정산도의 변화는 세 품종간에 차이는 없었지만, 숙성이 진행될수록 증가하는 경향을 보였다. 탁도변화는 꽈리고추가 가장 낮았고, 청양고추가 가장 높았으며, 숙성이 진행될수록 모두 탁해지는 경향을 보였다. 또한 피클의 경도변화는 풋고추는 0일에 45.12g 청양고추는 56.68g, 꽈리 고추 42.12g의 경도를 보였으며, 숙성최종단계인 25일에는 풋고추 20.33g, 청양고추 25.12g, 꽈리고추는 17.81g으로 꽈리고추의 경도가 가장 낮았고, 청양고추는 세 품종 중에서 가장 높은 것으로 나타났으며, 세 품종 모두 숙성이 진행될수록 경도가 현저히 낮아지는 것으로 나타났다.
