Heating characteristics for retort pouches of Kimchi heated in hot water were determined as a function of various parameters for processing. Processing conditions in laboratory and commercial retort were also evaluated on the basis of storage test. D values for Lactobacillus plantarum isolated from test sample ranged from $D^{1.08}\;to\;D^{0.18}$ and z value was $10.5^{\circ}C$. Thermal diffusivity of Kimchi increased from 1.15 to $1.44{\times}10^{-3}cm/s$ by blanching for 15 min at $80^{\circ}C$. The rate of heat penetration was significantly decreased with increasing the thickness of the pouch although the decreases was less significant below 1.0cm thickness. Increasing in the ratio of solid to syrup up to 90:10 proportionately decreased $f_h$ value, but above the ratio $f_h$ values were nearly constant.

Schisandra chinensis is a traditional herbal medicine that is widely spread in Korea, Japan, and China. The fruits of S. chinensis Bailon, known as omija in Korea, have traditionally been used for the treatment of coughs, fatigues, and insomnia. Up to now, there have been several reports for the identification of major lignan compounds and their quantitation in S. chinensis extracts. To the best of our knowledge, however, there is no report on the analysis of lignans in omija wine and omija cheong (sugared omija or omija sugar syrup). In the present study, seven dibenzocyclooctadiene lignans (gomisin A, gomisin B, gomisin C, gomisin N, schisandrin, deoxyschisandrin, and wuweizisu C) in omija wine and omija cheong were analyzed and quantitated using liquid chromatography-tandem mass spectrometry. Among seven lignans, pharmacologically active gomisin A, schisandrin, and deoxyschisandrin, which are major components in fruits of S. chinensis, were the most abundant lignans in omija wine and cheong. The content of lignan in omija wine was in the order: schisandrin > gomisin A > deoxyschisandrin > gomisin N > gomisin B > gomisin C > wuweizisu C. The concentration of deoxyschisandrin and gomisin N in omija wine was approximately 2.0- and 6.0-fold higher than for omija cheong. Additionally, this study provided a systematic identification of lignans in omija wine and cheong and indicated that the omija wine and cheong might be of value for their dietary application.

In this study, we investigated the names and various types of "kwa-jung" along with their recipes and ingredients occurring in Korean cookbooks published before the 17th century. The kwa-jungs were classified into 7 groups including Yoomilkwa, Yookwa, Dasik, Junkwa, Kwapyun, Yutganjung and Dang. A total of 72 kinds of kwa-jung were found. 26 kinds of Yoomilkwa, 18 kinds of Yookwa, 7 kinds of Dasik, 10 kinds of Junkwa, 1 kind of Kwapyun, 3 kinds of Yutganjung and 8 kinds of Dang. Among the types of Yoomilkwa, Yackwa was recognized as the best food according to the references. Also the cooking methods for items had a tendency to become simpler as society became modernized. Original and rare Ingredients were often substituted with other items that could be found more easily where people lived As recorded, the Yookwa group included kangyung, sanja, and bingsakwa. And as society became modernized, people tended to buy Yookwa in the store rather than making it at home due to its complicated and often difficult cooking process. The Dasik items were a kneaded mixture of flour, or the flour of chestnuts, with honey. These were formed into various patterns like birds, animals, butterflies, tree leaves and flowers, or as ki-wha by using printing cooking utensils Honey was used as a sweetener and as a combining material. The Junkwa consisted of roots or fruits that could be easily obtained these cooked or raw foodstuffs were then mixed with sugar and simmered. The Kwapyun used sour fruit juices as a main ingredient. These were then combined with sugar and simmered and allowed to harden. Then they were cut into square shapes after cooling. Yutkangjung was a mixture of yut, chochung, honey or syrup and pine nuts. which was combined over low heat. After mixing and stirring it was cut into square shapes. Finally, the Yut was typically cooked with grains and powdered malt and stirred until thickened.

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.

The purpose of this study was to investigate the effects of adding various amounts of ingredients on the physicochemical and sensory characteristics of Bokbunja-jelly. The proximate composition of Bokbunja-jelly was 19.0% for the moisture and 0.8% for the crude protein. The Hunter L-values of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose were higher than that of Bokbunja-jelly prepared by adding 20 g RME or 100 g sucrose. The Hunter b-values of Bokbunja-jelly prepared by adding 20 g RME or 120 g sucrose was higher than that of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose. The hardness and chewiness were increased with decreasing Rubus coreanus Miquel extracts. According to the results of the sensory evaluation, no significant differences in flavor, sweetness, hardness, elasticity and overall qualities were found. According to the results of physicochemical properties and sensory evaluation, the optimal recipe for preparation of Bokbunja-jelly was determined to be 240 g water, 120 g sugar, 110 g glucose syrup, 4 g agar, 20 g Rubus coreanus Miquel extracts and 0.3 g Rubus coreanus Miquel flavor.

This study was carried to investigate the changes in physical and chemical properties of Yukwa during preparation with addition of antioxidants and to develop its storage condition. Antioxidants (tocopherol and Oxyfos) were used in syrup coating and the packaging materials used were PET/EVOH $(16\;{\mu}m)/PL$ : P1 and PET/EVOH $(24\;{\mu}m)/PL$ : P2 (YOP1: P1 with Oxyfos, YOP2 : P2 with Oxyfos, YTP1 : P1 with tocopherol, YTP2 : P2 with tocopherol). Color values measured for Yukwa showed that L values of YOP1, YOP2, YTP1 and YTP2 were changed little during storage while a and b values of YOP1, YOP2, YTP1 and YTP2 were slightly decreased. Hardness and chewiness in textural properties were also decreased during storage. Yukwa packed in YOPl and YOP2 maintained less than 40 in peroxide value during for 12 weeks of storage period. The major fatty acid composition of frying oil were linoleic acid (54.2%), oleic acid (23.4%), palmitic acid (11.3%), linolenic acid (6.5%) and stearic acid (4.6%). There was no difference in composition of fatty acid during storage. Sensory evaluation (Yukwa odor and rancid odor) showed very similar results with determined by electronic nose. YTP1 and YTP2 had maintained sensory characteristics of Yukwa during 10 weeks storage.

Rheological properties and sensory characteristics of prickly pear jelly made from κ-carrageenan and glucomannan were examined. Prickly pear extract (PPE) fermented by Lactobacillus casei LS (isolated from soy milk curd residue) exhibited pH 3.12, 1.15% acidity (lactic acid) and 2.7 × 10/sup 9/ CFU/mL lactic acid bacteria. In the effect of concentration of fermented PPE, the jelly containing 4% fermented PPE had higher springiness and slightly lower hardness than that without fermented PPE, and was superior to color and taste. The hardness and brittleness of jellies were enhanced by the addition of 0.25% citric acid. The addition of 0.25% ascorbic acid resulted in the production of soft jelly like pudding. In the effect of concentration of κ-carrageenan, the hardness and springiness of jellies were increased by adding 0.75% κ-carrageenan, but was decreased by adding at the 0.9% level. In the overall preference of jellies including sweet and sour taste, higher score was obtained by the fortification of 0.6% and 0.75% κ-carrageenan, 0.25% citric acid and 30% fructose syrup.

The purpose of this research is to develop functional food with garlics(Allium sativum var. pekinense) as a healthy food. Fermented garlic broth(FGB)s were prepared with whole bulb of garlics preserved in sugar and sugar syrup, then fermented and aged at room temperature for 36 months. Biological activities of FGBs were tested antibacterial, antioxidative, fibrinolytic activities and analyzed for polyphenol contents. The total polyphenol contents of FGBs in 12~36 month fermented broth(870~885 mg/100 mL of broth) had significantly higher than those of 1~6 months fermented broths(p<0.001). The electron donating abilities(EDAs) and SOD-like activities of 24~36 month fermented broth had significantly higher than those of 1~6 months fermented broths(p<0.05). FGBs had shown strong antibacterial activities against four kinds of pathogenic bacteria(L. monocytogenes, S. aureus, E. coli O157:H7, and Sal. typhimurium). The fibrinolytic activities of 24~36 months fermented broth had more than twice of the fibrinolytic activity of plasmin. FGBs had increasing activities in antibacterial, antioxidative and fibrinolytic activity as the progress of fermentation period. FGBs can be used as natural antioxidant to prevent oxidative damage on normal cells probably because of their antibacterial, antioxidative and fibrinolytic activities.
