  • Physicochemical properties of pork patties formulated with black rice powder were investigated. Moisture contents of samples containing black rice powder were significantly higher than that of the control (p<0.05). Protein, fat, and ash contents increased with increasing black rice powder content. Uncooked and cooked pH values of samples increased with increasing black rice powder content. Lightness and yellowness of samples decreased with increasing concentration of black rice powder. Redness of cooked samples containing black rice powder was significantly lower than that of the control (p<0.05). Water holding capacity and cooking yield of samples increased with increasing black rice powder concentration. Diameter and thickness reduction ratio of samples decreased with increasing black rice powder content. Sensory evaluation of samples showed no significant difference between samples. Thus, black rice powder improved the quality of pork patties.

  • Protein concentrate was produced and succinylated from rice bran to assess and improve its functional properties for the purpose of expanding the uses of rice bran proteins. The most effective solvent for the extraction of rice bran proteins was 20% aqueous ethanol at pH 9. The protein content of rice bran protein concentrate produced was 70.0% and the total protein yield was 64.3%. The extent of succinylation of free amino groups in the modified products was 72.8%. Though the modified protein products showed good functional properties including solubility, emulsion properties, and oil absorption capacity, it did not form gel. Succinylation improved solubility and emulsion and gelling properties. These improvements in functionality will enhance the value of rice bran proteins, thus enabling them to be more competitive with other food proteins.

  • The traditional kanjang has been prepared by mixing meju and 18% saline solution, and fermenting for 60 days. The traditional kanjang is very salty and inferior in flavor and taste comparing with commercial fermented soy sauce. To improve the quality of traditional kanjang, Zygosaccharomyces rouxii H-62, a flavor-related mutant, was inoculated during fermentation. It was found that the addition of Z rouxii helped to improve the organoleptic quaity of traditional kanjang. The optimal condition for preparing traditional kanjang was to use 5L of 15.5% saline solution per meju. Meju must be cut into 12 pieces to get a proper total nitrogen and pure extract content. The optimal fermentatin temperature was 3$0^{\circ}C$. The prepared kanjang contained over 0.8% total nitrogen and 6.0% pure extract after 60 days of fermentation.

  • In order to fad out an efficient way of topdressing nitrogen fertilizer in mulch-cropping system of onion(Allium cepa L.), solid, slow-release, and liquid forms of nitrogen fertilizers were allied to cv. 'Changnyungdaego' various number of times at different time, with 5 topdress applications of solid fertilizer serving as a control. Whole basal application of conventional solid fertilizer and 2 slow-release fertilizers were labor-saving and showed improved storage quality of bulbs, but resulted in poor plant growth and considerably low yield due to fertilizer shortage from early April. This suggests that topdress application is necessary. Liquid form of nitrogen fertilizer was more effective for plant growth and yield and saving labor than the solid form. Early applications was effective for increasing yield and storage quality of onion bulbs harvested. Thus two applications of liquid form of nitrogen fertilizer in February and March at rome month interval are recommended in mulch crowing system of onion.

  • In this study, to explore the use of lotus leaf powder, quality characteristics of sponge cake manufactured with different levels of lotus leaf power were investigated. We discovered that the pH, gravity, and cooling temperature of sponge cake increased as the content of lotus leaf power additive increased compared with those of the control group. Likewise, L and b levels of sponge cake increased with increasing level of lotus leaf power; 20% lotus leaf powder appeared to show the highest L and B levels, but levels were lower than those of the control group. Sponge cake levels of hardness, springiness, and cohesiveness increased as the amount of lotus leaf powder additive increased. In sensory evaluation, overall acceptability of 5% lotus leaf powder was the highest. Thus, it is possible to develop sponge cake with improved health-oriented aspects by addition of 5% lotus leaf powder.

  • Effects of oligosaccharides substituted for sucrose on the sponge cake quality were investigated. Fructooligosaccharide and isomaltooligosaccharide were used as oligosaccharides. Oligosaccharides decreased batter specific gravity, and increased cake specific volume and expansion ratio, showing that oligosaccharides had higher foaming ability and foam stability than sucrose. Oligosaccharides darkened the crust and crumb color of cakes. Addition of oligosaccharides made cakes darker, softer, more moist and more acceptable as perceived by panels. The acceptability was significantly correlated with crust and crumb color, softness, moistness and flavor(p<0.01). The textural characteristics including hardness, chewiness and gumminess of cakes were decreased by replacing sucrose with oligosaccharides. The hardness, gumminess and chewiness among sensory characteristics were negatively correlated with acceptability(p<0.05). Therefore, oligosaccharides should be a good alternative for sucrose in cake making because the sponge cake quality was greatly improved by partial repacement of sucrose with oligosaccharides.
