  • Aroma compounds in 6 different Byeolmijang were extracted by SDE (simultaneous steam distillation extraction) and analyzed with GC (gas chromatography) and GC/MS (mass-spectrometry). The major aroma compounds in the 6 different Byeolmijang during aging were 1-octene-3-ol, hexanal, benzeneacetaldehyde, benzaldehyde, furfural, pyrazine compounds, benzyl-alcohol, furan compounds and phenol type compounds. Generally, benzeneacetaldehyde, benzaldehyde, furfural, pyrazine compounds and phenol type compounds were increased during aging. On the other hand, 1-octene-3-ol, hexanal, benzyl-alcohol and furan compounds were decreased during aging. 2-Heptenal and 2,4-decadienal in Daemaekjang, pyrazine and phenol type compounds in Sanghwangjang and phenol type compounds including phenol, 4-methoxy-phenol and 4-ethyl-phenol in Mujang were identified as major aroma compounds, respectively. The major aroma compound in Bizijang was 2,4-decadienal and in Sodujang, the major aroma compounds were 2,3-dihydro-benzofuran and 2-methoxy-4-vinylphenol. Linaool, geraniol, 6-elemene, 6-lonone and ledene were detected in Jigeumjang possibly due to the addition of powdered red pepper.

  • On the basis of the cookbooks and Data Base of the Korean Classics(http://db.itkc.or.kr/itkcdb/mainIndexIframe.jsp), this paper analyzed the fermented soybean listed in the general documents of the Chosun Dynasty(1392~1897) and the Goryeo Dynasty(918~1392). In the Goryeo Dynasty, there are 15 kinds of Jang(soybean paste or solution), among which are Jang (soybean paste fermented by mold)(6 documents), Yeomgjang, Yeomshi(2), and Gaejang(1). However, the cookbook at that time is defunct. The Goryeo Court relieved the famine-stricken people by proving them with Jang. In the Chosun Dynasty, 111 kinds of Jang were listed in the general documents, and 153 kinds in cookbooks. There were 55 kinds of general Jang, such as Jang(204), Yeomjang(63), Chojang, Goojang(7), and Gaejang(6), are listed in the general documents, and in the cookbooks, there are 55 kinds of Jang, such as Sookwhangjang(9 cookbooks), Daemaekjang(8), Myeonjang(8), Saengwhangjang (8), and Yooinjang(8), and among them, 13 kinds belong to the Chinese origin. A total of 9 Kinds of Ganjang(soybean solution fermented by mold), such as Soojang(30), Cheongjang(23), Gamjang(8), and Ganjang(3) are found in the general documents. In the cookbooks, 12 kinds of Jang, as Cheongjang(10), Cheonrijang(4), Ganjang(3), and etc., are listed. There were 9 kinds of Gochoojang(red pepper-soybean paste), such as Chojang(12), Gochojang(3), and etc., are listed in the general documents, and 9 kinds as Gochojang(7), Manchojang(7), rapid Manchojang(4), and etc., are in the cookbooks. In addition, 16 Kinds of Yookjang(fermented soybean-meat paste) as Haejang(15), Hyejang(11), Yookjang(11), and etc., are found in the documents, and 22 kinds as Nanjang(9), Gejang(6), Yookjang(5), Shoigogijang(4), and etc., are in the cookbooks. Eighteen Kinds of Shi(soybean paste fermented by bacteria) as Yeomshi(40), Shi(35), Shijang(6), and etc., are recorded in the documents, and 19 kinds as Jeonkookjang(6), Shi(4), Sooshijang(4), and etc., are in the cookbooks, and among them 11 kinds belong to the Chinese origin. Six kinds of Jipjang(aqueous soybean paste) as Jipjang(7), Uoopjang(4), Pojang (2), Jangzoop(2) are recorded in the documents, and 15 kinds as Jipjang(9), Zoopjeo(7), and Hajeoljipjang(5) are in the cookbooks. Soybean paste, or solution for relieving hunger is not recorded in the documents. However, the Chosun court, for the purpose of relieving famine-stricken people, used general Jang. Such 21 Jang to relieve the famine-stricken people as Pojang(7), rapid Jang(6), and Sasamgilgyeongjang(4) are listed in the cookbook. Geonjang(dried soybean paste), Nanjang (egg-soybean paste), Doojang(soybean paste), Maljang(random soybean paste), Myeonjang(wheate-soybean paste), Sodoojang (red bean-soybean paste), Yookjang(soybean-meat paste) and Jang(soybean paste) are recorded in the documents, as well as in the cookbooks. Chinese-original Jang and Shi are recorded in the cookbooks, with no list in the general documents. Therefore, it seems that it didn't pass down to the general public.

  • Black soybean paste (BSP) is a bealmijang manufactured with barley flour and black soybeans. This study investigated the quality characteristics of BSP prepared with Bacillus subtilis HJ18-4 (HJ18-4). ${\alpha}$-Amylase and protease activities of BSP rapidly increased on day 6 and day 9, respectively, ($41.45{\pm}0.3-42.72{\pm}0.16$, $21.84{\pm}0.24-23.11{\pm}0.35unit/g$) after which the activities were constant or decreased slightly. Amino type nitrogen contents increased until day 23 ($173.78{\pm}3.51-195.63{\pm}1.51mg\;%$), whereas ammonia type nitrogen sharply decreased on day 9. On day 30, lactic acid bacteria counts were higher compared with the initial count ($7.91{\pm}0.05-8.17{\pm}0.02log\;CFU/g$). Meanwhile, B. cereus and total aerobic counts in HJ18-4 added BSP were lower than that in the control. These results implied that BSP could be edible after 30 days of fermentation, and the addition of HJ18-4 in meju could contribute to the safety of the black soybean paste by the inhibition of B. cereus growth.
