  • Gulbi were made by salting Yellow corvenia (Pseudosciaena manchurica) with the in three ways: the dry salting method with bay salt, the dry salting method with purified salt or with the abdominal brine injection method with purifie salt. The half of the sample was dried by the control system of temperature and humidity: the other part was dried by the natural condition. In fresh muscle, the content of IMP, hypoxanthine, inosine and AMP were $13.40,\;9.28,\;3.01{\mu}mole/g$ and trace amount, dry basis, respectively. In fresh egg, the content of AMP, hypoxanthine, inosine and IMP were 13.98, 6.56, 1.98 and $1.93{\mu}mole/g$, dry basis, respectively. During the drying process of Yellow corvenia, the content of hypoxanthine increased remarkably, while the content of AMP, IMP and inosine decreased ana remained as trace amount. It can be suggested that the characteristic flavor of Gulbi is not attributed to the nucleotides and their related compounds but rather to free amino acids.

  • Gulbi were made by salting fresh Yellow corvenia (Pseudosciaena manchurica) in three ways; the dry salting method with bay-salt, the dry salting method with purified salt or the abdominal brine injection method with purified salt. Half of the sample was dried by controlling temperature and relative humidity and the other part was dried under the natural condition. The moisture content of the samples were decreased more rapidly by the controlled system than by the natural condition. The lipid content and the iodine values of the muscle and skin of the Gulbi were decreased slowly with laps of drying period. The peroxide values of the sample were increased to its peak after 10 days of drying, and were decreased rapidly thereafter. Both acid values and the thiobarbituric acid values were increased. The deterioration of lipids during Gulbi processing was not notable depending on the salting method, but the natural drying condition affected more severely in their deterioration.

  • The aim of this study was to offer information about appropriate processing method for dry cured-ham with controlled ripening condition. In this study, three different treatments were performed: High salt group (HS), 18 hams were salted with 70 g $kg^{-1}$ salt (w/w) Middle salt group (MS), 18 hams were salted with 50 g $kg^{-1}$ salt Low salt group (LS), 18 hams were salted with 30 g $kg^{-1}$ salt. Also three drying periods were applied (180 days, 270 days and 360 days). The weight loss in HS was higher (5.62%) on curing step and in LS was higher (12.35%) on post-salting step compared to other groups. On fermentation stage, weight loss of HS was higher than that of LS (p<0.05). Weight loss on drying was increased as the drying period passes (p<0.05). Moisture contents were significantly (p<0.05) decreased and fat contents were significantly (p<0.05) increased in all treatment groups as drying period increased. The different drying periods affected fatty acid compositions on all salting levels; saturated fatty acid contents were increased (p<0.05) with more drying, whereas unsaturated fatty acid contents were decreased (p<0.05) as drying period increased.

  • The optimal fermentation conditions for processing of the salt-fermented oysters in olive oil were examined. The penetration of salt into oyster meat was completed within 1 day after brine salting or dry salting. The amino nitrogen contents of salt-fermented oyster was increased slightly up to the 20th day during salt-fermentation at 5$\pm$1$^{\circ}C$. The hardness of the salt-fermented oysters was increased up to the 10th day, and then softened gradually by some parts of the tissue were hydrolyzed. The viable cell counts didn't change overall at the non-salt medium, but it was increased definitely up to the 15th day at the 2.5% salt medium during salt-fermentation. Based on the results of sensory tests, the salt-fermented oyster at 5$\pm$1$^{\circ}C$ for 15∼20 days showed the best flavorous condition. The optimal condition for the salt-fermented oyster in olive oil was to ripen at 5$\pm$1$^{\circ}C$ for 15 days by brine-salting in saturated saline solution-oyster sauce (2:1).

  • This study examined the total glucosinolate (GSL) and isothiocyanate (ITC) contents according to different processing conditions; fresh Kimchi cabbage (Brassica rapa L. ssp. pekinensis), salted Kimchi cabbage and kimchi (storage temperature $4^{\circ}C$ and $20^{\circ}C$) using two different cultivars (Bomatnorang and Chunkwang). Four GSL peaks representing gluconapin, glucobrassicanapin, glucobrassicin and 4-methoxyglucobrassicin were detected in Kimchi cabbage by HPLC and HPLC/MS analysis. The total GSL contents of fresh Kimchi cabbage of Bomatnorang and Chunkwang were $21.37{\pm}1.06{\mu}g/g$ dry weight (DW) and $20.96{\pm}3.33{\mu}g/g$ DW, respectively. After salting, the total GSL contents of salted Kimchi cabbage decreased by 39% and 52% in Bomatnorang and Chunkwang, respectively. Finally, the total GSL contents of kimchi after storage at $20^{\circ}C$ decreased by 83% and 56% in Bomatnorang and Chunkwang, respectively. The extracted ITC contents were analyzed by GC/MS. Three ITC peaks were detected in Kimchi cabbage representing 2-phenylethyl ITC, 3-butenyl ITC and 4-pentenyl ITC. The 2-phenylethyl ITC levels increased during the salting process but this generally fell during storage at $20^{\circ}C$ as kimchi. The 3-butenyl ITC levels of Kimchi cabbage according to processing decreased rapidly due to salting and then decreased slowly during storage as kimchi. The 4-pentenyl ITC of Kimchi cabbage was lost during the salting process. The results for the change in GSL and ITC contents during the kimchi making process will be used in the food industry.

  • In order to assess the protein nutritional quality of salted and dried yellow corvenia, which was prepared using the different salting methods like dry and brine salting, the changes of trypsin indigestible substrate(TI) and in vitro apparent protein digestibility were studied during storage at room temperature($24{\pm}1^{\circ}C$). It was also examined the retention of available lysine and formation of nonenzymatic brown pigments under the same conditions of preparing and storage mentioned above and confirmed the relationship between in vitro digestibility and the antinutritional factors, such as nonenzymatic browning, unavailability of lysine and TI content, TI content was gradually increased during the storage and in showed $1.5{\sim}2$ times more after 57 days storage than at the initial stage which ranged from 0.11 to 0.17mg/g solid. Of all the products, $25\%$ brine salting product contained the least TI content in 0.21 mg/g solid, while $10\%$ dry salting products was the most abundant in 0.30 mg/g solid using Hamerstrand method(1981). In vitro protein digestibility of all dried products was decreased significantly up to 30 days as the contents of TI increased, except $25\%$ brine salted products. After storing for 57 days, the in vitro digestibility was only $4\%$ drip showed in $25\%$ brine salted products. The nonenzymatic brown pigments were also developed on the level of available lysine reduced as in vitro protein digestibility was decreased throughout storage. Of all the various salted and dried products of yellow corvenia, $25\%$ salting product showed the lowest rate of browning development and loss of available lysine. Therefore, it was revealed that unavailability of lysine and development of nonenzymatic brown pigments were major factors influencing the protein quality in salted and dried yellow corvenia.

  • The physicochemical and microbial characteristics of pickled cucumber prepared with dry salting method, which has been used for industry, were investigated. Salting and storage conditions were HSHT $(30\%,\;25^{\circ}C)$, MSMT $(21\%,\;15^{\circ}C)$, MSLT $(21\%,\;0^{\circ}C)$, LSMT $(15\%,\;15^{\circ}C)$ and LSLT $(15\%,\;0^{\circ}C)$. Acidity was lower, and pH was higher in higher salt concentration as well as lower temperature groups. At the storage of 165 days, acidity and pH reached to $0.21\%$ and 4, respectively in MSLT and HSHT, of which conditions fermentation was retarded, compared to the other groups. During storage of pickled cucumber, greenness (-a) of Hunter color system showed the highest in MSLT ranged from -10.70 to -8.08, while in LSMT, the lowest to 1.17. Total microbial and lactic acid bacteria number in HTST and MSLT were the lowest than in other groups, while tile highest in LSMT. Yeast was not detected in HSHT and MSLT after 36 days of storage, while higher in LSMT Texture profile analysis exhibited that fracturability (2,318 g and 2,318 g) and hardness (849 g and 702 g) were highest in HSHT and MSLT, compared to the other groups. Scores of over-all preference for MSLT and LSLT were higher with 8.8 and 7.6, respectively, compared to the other products (p<0.05). Based on these results, lower saltiness and lower storage temperature condition was better for pickled cucumber preparation in industry.

  • This study aims to investigate the food preservation methods adopted by the Joseon Dynasty, which existed before the 17th century. A total of 232 food preservation methods were discovered in 25 books, and could be classified by their targeted food types: vegetables (84), sea foods (60), meats (41), fruits (37), and others (10). Depending on the preservation method applied, they are classified as food drying, soaking, mud cellar preservation, and other preservation. Food drying is further classified into 8 sub-types: drying, sun-drying, shadow-drying, wind-drying, dry heat, combined drying, smoking, and others. Soaking could be sub-divided into using salt, ash, dry sand, bran, fermented paste, wet distillers grains, oil, and others. Mud cellar preservation is sub-classified into installing shelf inside the mud cellar, making the mud cellar for food preservation, and making hole or underground tunnel for food preservation. Other food preservation methods include minimizing moisture loss by applying beeswax on a section of the vegetable stem, and cutting the vegetables or fruits with their branches and leaves for food preservation.

  • The purpose of this study was to determine content of biogenic amines (Histamine, Cadaverine, Putrescine) in the salted mackerel, canned mackerel, mackerel pike, and freeze dried mackerel pike (Guamegi) collectively, all were purchased in the market. Salted mackerel was purchased at five markets (A, B, C, D, and F market) and stored for 10 days at $4{^{\circ}C}$. At the time of purchase, salted mackerel purchased at markets A, B and C was tested for biogenic amine, yet nothing was detected. However, salt mackerel purchased at market D was tested and the histamine concentration was 0.5 mg/100g. Mackerel from market F, exhibited content levels of 0.5 mg/100g histamine and 1.6 mg/100g cadaverine. Those make certain safety during self-life but that purchased F market gradually increased biogenic amine during storage. Prepared salted mackerel of varying levels of freshness and processing methods were analyzed for biogenic amines. Salting process was performed using functional brine salt. VBN (volatile basic nitrogen) was used to establish freshness levels of salted mackerel. Analyses of mackerel muscle determined the values of freshness to be 9.2 mg/100g (good freshness), 18.2 mg/100g (bad freshness), respectively. After 40 days of storage, the content of histamine, cadaverine, putrescine in the freshness of salted mackerel was 2.0 mg/kg, 2.4 mg/kg and 0 mg/kg, respectively. The content of histamine, cadaverine, putrescine in salted mackerel of poor freshness was 71.3 mg/kg, 22.9 mg/kg and 17.8 mg/kg, respectively. It was concluded the presence of biogenic amines during the salting process of salted mackerel significantly effected freshness of materials. The presence of biogenic amines were detected in mackerel that underwent the salting process after 1 month of storage at $4{^{\circ}C}$. The levels of biogenic amines in the brine salted mackerel were higher than those found in dry, salted mackerel; however, the freshness of fish had an insignificant effect on biogenic amines. The presence of histamine was detected in small quantities in canned mackerel and mackerel pike from three companies. Alternatively, cadaverine and putrescine were not detected. Guamegi, vacuumed packed or sealed with a rope was purchased from three markets (A, B, C seafood company). Guamegi was stored and observed for 180 days at $-20{^{\circ}C}$. Histamine was detected in small quantities in all products stored at $-20{^{\circ}C}$. Levels of histamine was dependent on the types of packaging, rope packaging yielded the highest level. However, other amines were not detected.
