This study was conducted to standardize the cooking methods of Omija-Pyuns and to investigate the effect of different starch densities (6% 7%, 8%, 9%) on the texture and taste of Omija-Pyuns. The results of these studies were as follows: 1) It was better for Omija to soak for 18 hours. The most favorite Mungbean starch density of 7% of Omija-Pyuns has the degree of lightness of 18.90, the degree of redness of 19.18, and the degree of yellowness of 3.98. 2) The Brix of syrup used for Omija-Pyuns was 49.4%. 3) As a result of the measurement of texture through Instron, if Mungbean starch density is increased, its hardness also increase. Each of the Omija-Pyuns (6%, 7%, 8%, 9%, in density) has showed its effection (p<0.05). 4) The result of the sensory evaluation showed that the Omija-Pyuns produced with Mungbean starch density of 7% was most preferred in appearance and overall taste, but it did not show the statistical effection (p<0.05) from the Omija-Pyuns produced with Mungbean starch density of 8%. The flavour was highest in Omija-Pyuns of 6%, and as the density was increased, the flavour decreased.

This study was conducted to examine the sensory quality, the degree of gelatization, pH, color, texture and moisture content of paeksolgi with omija water extracts added. The results of the analysis were as follows : The moisture contents of Paeksolgi were about 36~39%. The L value of the control group was 83.04 The degree of the colour was (L value: 71.82~86.56), (a value: -1.33~+0.78), (b value : 7.84~9.78). As the amount of omija water extracts was increased. the L and a values increased, but the b value showed a similar value, It was found that the yellowness decreases by increasing the soaking time of each type. The gelatinization of Paeksolgi with omija water extracts added was decreased as the amount of omija was increased. The sensory quality of paeksolgi with 5~7% omija water extracts added showed the most favorable sensory evaluation. In view of color, after taste and overall quality, the D$_2$group of Paeksolgi was preferable to the other paeksolgi groups with omija water extracts added.

This study determined the effects of soybean oil$2\%$) and chitosan($1\%$) on the quality characteristics of Omija Jelly made of various starches (mungbean starch, cowpea starch and corn starch). RVA(Rapid Visco Analyzer) viscosity was measured for starches suspended in Omija aextract with $2\%$ soybean oil and $1\%$ chitosan. The color value, syneresis, texture(rupture test and TPA test) and sensory properties of the samples were measured. Gelatinization of cowpea starch was expedited by adding soybean oil and chitosan. Otherwise, gelatinization of mungbean starch and com starch was retarded by adding chitosan. The lightness(L) and the syneresis of Omija Jelly with soybean oil and chitosan were decreased, indicating the increased transparency and stability of Omija Jelly. Rupture stress and rupture energy of Omija Jelly were decreased by adding soybean oil. Rupture stress was increased and rupture energy was decreased by adding chitosan. The addition of soybean oil improved texture of Omija Jelly, indicating that the springiness, cohesiveness and chewiness of Omija Jelly were increased and adhesiveness was decreased. By adding chitosan, the springiness and hardness of Omija Jelly were increased and the cohesiveness and adhesiveness were decreased. The overall acceptability of Omija Jelly made of $6%$ or $7\%$ cowpea starch and com starch was increased by adding soybean oil and chitosan, but the quality characteristics of Omija Jelly made of mungbean starch were not influenced by additives such as soybean oil and chitosan.

This study was conducted to investigate the antioxidant activity of Kochujang following the addition of Omija (Schizandra chinensis Baillon) by-product extract powder. This study specifically investigated the total levels of phenolics and flavonoids, the activities of DPPH and ABTS radical scavenging, and FRAP (ferric reducing antioxidant power). Our results showed that the total phenolic and flavonoid contents of unmodified Kochujang were 4.06 mg TAE/g and 2.87 mg TAE/g, respectively, and that the total phenolic and flavonoid contents of Kochujang with added Omija by-product extract powder were 3.89~5.19 mg TAE/g and 3.11~5.35 mg TAE/g, respectively. As more Omija by-product extract powder was added, the more the total levels of phenolic compounds and flavonoids increased. This study found that DPPH radical scavenging activity in unmodified Kochujang was 25.8% and that in Kochujang with added Omija by-product extract powder was 27.1~39.7% each. These results indicate that Omija by-product extract powder has possibility not only in Kochujang products but also as a functional food with antioxidant activity characteristics. These results also indicate that adding Omija by-product extract powder to Kochujang had significant effects on overall acceptability. Thus, the addition of 5 or 10% of Omija by-product extract powder is desirable for making Kochujang.

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.
