  • This study compares the major nutritional components of the leaf, flesh, and seed of dry loquat (Eriobotrya japonicaLindl.). Among proximate compositions, the crude fat, crude ash, and dietary fiber of the leaf exceeded those of the seed and flesh, whereas the carbohydrate content of the leaf was lower than that of the seed and flesh. The main component of free sugars in the leaf, flesh, and seed was fructose. Total amino acids of the leaf, flesh, and seed were 552.43, 63.00, and 260.29 mg%, respectively. Although the amino acid composition of the leaf, flesh, and seed varied, glutamic acid and ${\gamma}$-aminobutyric acid were the major amino acids in the leaf, flesh, and seed. Major fatty acids of total lipid were oleic acid and stearic acid in the leaf and seed, and the major acid was linoleic acid in the flesh. Major organic acids were oxalic acid in the leaf, maleic acid in the flesh, and citric acid in the seed. Vitamin C content was higher in the seed than in the leaf and flesh.

From the texture of lotus leaf powder added mung bean as per the storage period, the hardness of fresh Cheongpomuk were $0.38g/cm^2$ from control group, $0.40g/cm^2$ from CCD 1% group, $0.42g/cm^2$ from CCD 3% group, $0.37g/cm^2$ from CCD 5% group, $0.42g/cm^2$ from GGD 1% group, $0.39g/cm^2$ from GGD 3% group, $0.35g/cm^2$ from GGD 5% group, $0.39g/cm^2$ from JLD 1% group, $0.33g/cm^2$ from JLD 3% group, and $0.32g/cm^2$ from JLD 5% group. It has shown that JLD 5% group was the lowest, while CCD 3% group and GGD 1% group were the highest, and there were significant differences among sample groups. For DPPH radical scavenging ability, that of GLD 5% group was 22 times higher than that of control group. In addition, the tendency was increasing by increasing the adding rate of lotus leaf powder though there was some tolerance among sample groups. For total phenolic compound content, that of control group was 6.65 mg CE/100 g, and others were 7.48 mg CE/100 g from CCD 1% group, 15.82 mg CE/100 g from CCD 3% group, 20.15 mg CE/100 g from CCD 5% group, 15.55mg CE/100 g from GGD 1% group, 23.02 mg CE/100 g from GGD 3%, 26.95 mg CE/100 g from GGD 5% group, 3.92 mg CE/100 g from JLD 1% group, 16.72 mg CE/100 g from JLD 3%, and 26.58 mg CE/100 from JLD 5% group. From the analyzing result of responses for color and scent, taste, elasticity, and total preference of lotus leaf powder added Cheongpomuk between two panel groups, there was significant difference for the color, higher from professional cooking instructor group, but there were no significant difference between two groups for all other factors among professional cooking instructors and cooking department students. According to the results, it is expected that various functional foods can be developed by utilizing lotus leaf powder, depending on the growth condition and cultural environment of each region by adding 3% of lotus leaf powder, would be the most suitable recipe for Cheongpomuk.

  • This study was carried out to investigate the effect of lotus root and leaf powder on the quality characteristics of pork patty stored at $3^{\circ}C$ for 9 days. The pork patties were of four types: nothing added(control, T0), 0.5% lotus root powder added (T1), 0.25% lotus root and 0.25% lotus leaf powder added (T2), and 0.5% lotus leaf powder added (T3). The $a^*$ value tended to decrease with longer storage period (p<0.05). The $L^*$ and $a^*$ value of T3 had the lowest value among the samples, the $b^*$ value T2 and T3 were higher than those of T0 and T1 (p<0.05). Water holding capacity decreased with longer storage period (p<0.05), the water holding capacity, cooking loss, increase rate of thickness and decrease rate of diameter were not significantly different among the samples. Hardness and chewiness increased and springiness decreased with longer storage period (p<0.05). The pH creased with longer storage period (p<0.05), but the VBN content not changed during storage. The TBARS values increased with longer storage period (p<0.05), and those of T0, T1, T2 and T3 were 4.57, 1.85, 0.43 and 0.41 mg MA/kg, respectively, after 9 days of the storage. The result suggest that the addition of lotus root and leaf powder at the same time, or addition of lotus leaf powder can be applied to pork patty to its functionality.

  • The objectives of this study were to investigate the physicochemical characteristics of soybean leaves in different cultivars and to develop a soybean curd prepared with soybean leave powder as a functional food. Four cultivars (Daewonkong leaf, Daepungkong leaf, Hwangguemkong leaf, and Seoritae leaf) were selected for this experiment. A significant difference was observed in the proximate composition of soybeans leaves (p<0.05). Soybean leaves had the highest content of carbohydrates. The mineral composition and isoflavone content in soybean leaves were significantly different among the cultivars (p<0.05). In particular, Daepongkong leaf had the highest content of genistein, daidzein, and total isoflavones. This study was also conducted to determine the quality characteristics of a soybean curd developed from daepongkong leaf with various concentrations (0, 0.1, 0.2, and 0.3%) of soybean leaf powder (SLP). The soybean curd yield rate increased according to the level of SLP added, whereas the L and a color values decreased. In the sensory evaluation, intensity scores for color, after taste, leafy taste, and chewiness were highest for the 0.3% soybean curd. The soybean curd with 0.2% SLP soybean milk attained the highest overall acceptability score. These results showed that soybean leaf was preferred over soybean curd containing 0.2% soybean leaf powder.

  • This study was conducted to estimate the content of antioxidant components and investigate the antioxidative activity of mustard leaf kimchi added pumpkin powder (P) and green tea powder (G). Mustard leaf kimchi added different ratios of P and G were prepared and fermented for 30 days at 5$^{\circ}C$ (properly fermented time). The contents of chlorophyll, total phenol, carotenoids and ascorbic acid in mustard leaf kimchi samples were estimated. The 30 day fermented mustard leaf kimchi added 0.3% P and 0.2% G had relatively higher content of antioxidant components than the other kimchi samples. Based on this result, antioxidative activities of mustard leaf kimchi added 0.3% P and 0.2% G and control kimchi were investigated, that is, methanol extracts of the mustard leaf kimchi samples were prepared and investigated the antioxidative activities. The antioxidative activity of mustard leaf kimchi added 0.3% P and 0.2% G was significantly (p<0,05) higher than control kimchi, and that of the 30 day fermented mustard leaf kimchi at 5$^{\circ}C$ was also significantly higher (p<0.05) than the fresh mustard leaf kimchi. Therefore, it is suggested that antioxidative activity of the 30 day fermented mustard leaf kimchi added 0.3% P and 0.2% G at 5$^{\circ}C$ was the best compared to the other kimchi samples.

  • Two experiments were carried out on a laboratory scale. The first involved a study of the effect of green tea on characteristics of fermented juice of epiphytic lactic acid bacteria (FJLB). FJLB was treated with 50 g/L of green tea products as follows: new shoot powder (FJLB+N), leaf powder (FJLB+L), commercial powder (FJLB+P), sterilized new shoot powder (FJLB+SN), sterilized leaf powder (FJLB+SL) or sterilized commercial powder (FJLB+SP). FJLB without any additive was also prepared (Untreated FJLB). After incubation, the number of microorganisms in FJLB were studied. Subsequently, these FJLB were applied at 10 ml/kg to chopped rhodesgrass to study their effects on fermentation. Compared with untreated FJLB, the addition of green tea increased (p<0.05) lactic acid bacteria (LAB) and also aerobic bacteria counts in FJLB. At 60 d of ensiling, all the FJLB treated silages were well preserved, pH and butyric acid content were lower (p<0.001) and lactic acid was higher (p<0.001) than that of the control. Lactic acid content was significantly higher (p<0.001) with treated FJLB than with untreated FJLB. FJLB treated with sterilized green tea decreased (p<0.001) the pH and the lactic acid content was higher (p<0.001) than that in the unsterilized green tea silages.
