  • A traditional Korean seafood (fermented anchovy) is made from the muscle and viscera of anchovies Engraulis japonica. This study was undertaken to investigate the effect of retorting condition on the quality of canned, salt-fermented anchovy fillet using red pepper paste with vinegar. Salt-fermented anchovy fillets were prepared by fermenting anchovies with salt (15%) at $5^{\circ}C$ for 15 days, and then cold air drying the fillets for 1 hour. Each batch of dried fermented anchovy fillets (60 g) was filled with 35 g of mixed red pepper paste with vinegar (red pepper paste 64%, vinegar 2%, starch syrup 13%, sugar 14%, coke 6%, soju 0.4%, crushed garlic 0.3%, ginger 0.3%), placed in a can (RR-90), seamed using a vacuum seamer, and sterilized for either Fo 9 or 11 min in a steam system retort at $121^{\circ}C$. After sterilization, we measured the pH, total volatile basic nitrogen (TVB-N), amino-N, color value (L, a, b), texture profile, thiobarbituric acid (TBA) value, sensory evaluation, and viable bacterial count of the canned fillets. We did not detect viable bacterial counts in cans subjected to either sterilization treatment, and there was no difference in physicochemical and sensory quality between the two. In fact, most sensory evaluators reported difficulty distinguishing the products. Thus, our results show that sterilization for Fo 9 min is preferable to that for Fo 11 min in the preparation of canned salt-fermented anchovy fillet using red pepper paste with vinegar.

  • This study was investigated for the purpose of obtaining basic data for application to the canning process of salt-fermented anchovy Engraulis japonica fillet using tomato paste. The salt fermented anchovy fillet was prepared by fermenting anchovy fillet with salt 15% at $5^{\circ}C$ for 15 days and then cold air drying the salt-fermented anchovy fillet for 1 h at $16{\pm}1^{\circ}C$. The dried salt-fermented anchovy fillet 85 g was filled with 60 g of tomato paste sauce (tomato paste 42%, gum guar 1.0%, salt 2.0%, starch syrup 2.0%, cooking wine 1%, water 52%) and seamed by vacuum seamer in 301-3 can, then sterilized at Fo 9 and 11 min in a steam system retort at $121^{\circ}C$, respectively. The factors such as chemical composition, pH, total volatile basic nitrogen (TVB-N), amino-N, color value (L, a, b), texture profile, thiobarbituric acid (TBA) value, sensory evaluation and viable bacterial count of the canned salt-fermented anchovy fillet were measured. Texture value of the product sterilized at Fo 11 min was higher than at Fo 9 min condition. In both sterilized cans, the viable bacterial counts were not detected. There was no remarkable difference in physicochemical between sterilization conditions. As a result of sensory evaluation, most sensory evaluation inspector judged that it was difficult to distinguish the sensory difference of both products sterilized at Fo 9 min and at 11 min. The results showed that sterilization of Fo 9 min was more desirable than that of Fo 11 min to prepare canned salt-fermented anchovy fillet using tomato paste sauce, because this condition is more economical.

  • This experiment was conducted to find the effect of gibberellin paste on the growth and maturation of 'Hosui' pear fruit and to develop a cultural technique in the middle area of Korea, where fruit quality is often poor due to the short growing season. The application of $GA_{3+4+7}$ paste on the petioles at the young stage of development resulted in the early increase of fruit diameter and weight. Although fruit firmness was slightly low by the $GA_{3+4+7}$ paste treatment, compared to that of control, there were no differences in other quality actors such as soluble solid content and acidity. However, $GA_3$ alone did not affect the fruit growth and quality. Are increase of ethylene evolution of fruit was not confirmed hut ground color development was hastened, resulting in the stimulation of maturity by 3~5 days. Thus, these results may be applicable to the production of high quality 'Hosui' pears in the area where growing season is relatively short.

  • The aim of this study was to develop a seasoning paste fermented by Aspergillus oryzae and Bacillus subtilis using three edible insects: Tenebrio molitor larvae, Gryllus bimaculatus, and Bombyx mori pupa. No significant changes in pH and titratable acidity were observed between the insect pastes and soybean control during a 5-week fermentation process. The amino nitrogen was 0.35-0.50% (w/w) in the early stage of the fermentation and increased to 0.72-0.78%. The total nitrogen was 2.36-3.62% (w/w) in the early stage and was preserved during the fermentation period. Free amino acids of the insect pastes were similar to those in soybean paste. In general, the fermented insect pastes showed a lower flavor and color than soybean paste but B. mori pupa-fermented paste did not show any significant difference in preference from soybean. Glutamate, aspartate, lysine, phenylalanine, arginine, and serine were found to affect taste preference. It was possible to ferment edible insect protein to produce a fermented seasoning paste like Korean doenjang.

  • Fifty three microbes, mainly fungal genera, were isolated from sixteen Mejus of different region. From those collected isolates, Meju was manufactured and assayed for the activities of amylase and protease. Correlations between sensory evaluation and color measurement were investigated with Kanjang (soy sauce) prepared by each pure inoculation. Color of Kanjang was quite various depedning on fungal genera, but the taste was not quite related with the activity of amylase or protease. This fact might mean that taste of Kanjang depended on the complicate mechanistic action of enzyme for the substrate involved in the soybean hydrolysis. Thus, the taste of Kanjang origenated from Korean traditional Meju seems to belong to complex flora of participated fungal genera as well as Bacillus. sp.

  • Ag-coated Cu particles were prepared by dropping method of coating agent and were evaluated by scanning electron microscope and color difference meter. The shape of Cu particles having obvious crystal plan and edge was changed spherically according to the increase of Ag coating amount. When the Ag coating amount was 50 wt% to Cu particles, the whiteness of Ag-coated Cu particles was almost similar to that of pure Ag particles. Adding $NH_4$OH in reductant solution could increase effectively the whiteness of the Ag-coated particles. The Ag-coated particles having the highest whiteness was obtained when the content of hydrazine in reductant solution was 0.48 M.

  • Though traditional seasonings are widely used in many dishes, however, no attention has been paid to the investigation of their effects on quality characteristics of food products. The present investigation was undertaken to study the effects of incorporating several traditional seasonings including doenjang (fermented soybean paste), gochu-jang (red pepper paste), fresh medium-hot, and hot peppers, and fresh garlic on the lipid oxidation, cholesterol content and sensory characteristics of fermented sausages. Six fermented sausage treatments (5 with 1% (w/w) each test seasoning and 1 without added test seasoning (control) were prepared. The addition of seasonings generally had beneficial effects on the improvement of fermented sausage's quality however the effects differed depending on the each type of seasonings added. Significant lower pH values were found in all fermented sausages made with the seasonings while, lower levels of lipid oxidation were found in the treatments with hot peppers and garlic as compared with the control (p<0.05). The treatment with seasonings did not cause color or texture defects in the products whereas the sausages made with gochu-jang had significantly higher Commission International de $l^{\prime}Eclairagea^{\ast}$ (redness) value in comparison with the control. Noticeably, incorporating doenjang, medium-hot peppers, hot peppers and garlic resulted in reduction of 26.50, 32.54, 47.04, and 48.54 mg cholesterol/100 g samples, respectively (p<0.05). Higher scores for the sensory traits such as aroma, taste, color and acceptability were also given for the sausages made with seasonings. The current work demonstrates that the test seasonings represent potentially natural ingredients to be used for producing healthier fermented sausages.

  • In this part of the studies on dielectric dehydration of foamed fish-starch paste, quality stability and shelflife of the product of which the preparation formula and processing conditions were described in the previous report (Lee et at., 1982) were determined by means of accelerated reaction test. The product was stored for 50 days under the conditions of temperatures at 35, 45, and 55$^{\circ}C$ in steady state and various water activities of 0.44, 0.52, 0.65, and 0.75, respectively. The loss of available lysine, the extent of TBA value, and the development of browning during the storage were measured and reaction kinetically analysed to assess quality stability and shelf-life of the product for the storage at room temperature of 25$^{\circ}C$. The extent of browning was accelerated with the increase of water activity and temperature marking the time to reach a limit of color and flavor deterioration, or to reach brown color density of 0.17 O.D./g at 420nm, 106 days at a$\_$w/=0.44, 35$^{\circ}C$, and 41 days at aw=0.65, 55$^{\circ}C$. These reaction rates resulted in a prediction of shelf-life, 130 to 110 days in the storage at au=0.44 to 0.75, 25$^{\circ}C$. The quality limit assessed by TBA values and sensory evaluation of rancidity was 87 days at a$\_$w/=0.44, 35$^{\circ}C$, and 30 days at aw=0.73, 55$^{\circ}C$ which gave a predicted shelf-life, 128 to 113 days at a$\_$w/=0.44 to 0.75, 25$^{\circ}C$ storage.

  • War against Japanese(1592-1599) and war against Manchurian(1636-1637), which had been occurred in Korean Peninsula throughout the history, and frequent trade with foreign countries since $18^{th}$ century have led to a distribution of foreign food into Korea. Several examples for this include tomato, apple, watermelon, maize, pea, cowpea, peanut, potato from China and red pepper, pumpkin, and sweet potato from Japan. Since these foods had been brought into Korea, they have been cultivated suitable for Korea's climate and land. Foreign foods with a few exceptions tend to have high calories. For instance, along with potato and sweet potato, pumpkin is considered a high-calorie food containing lots of starches as it becomes ripening. This helped a wide spread of the foreign foods across the nation where intake of high-calorie foods was critical for Korean people's nutrition at that time. Among those foods introduced from foreign countries, red pepper had a greatest impact on the dietary life-style of Chosun Dynasty. The use of red pepper has been greatly expanded from main ingredient to seasoning and garnishing in various forms of red pepper such as red pepper paste, red pepper powder, and thick soy paste mixed with red pepper. Red pepper was made eating habits is hot besides dye red colored to traditional food, because steaming and boiling is frequently cook method, fermentation food also food color is achromatic therefore food color is and mixture with red pepper, picked fish and chinese cabbage new kimchi culture came into being.
