  • The purpose of this study was to investigate the quality characteristics and antioxidant activities of noodles added with red lentil powder (RLP). Noodles were prepared by addition of 0, 15, 30, and 45% powder to flour of the basic formulation. RLP noodles were evaluated for their cooking properties (weight, water absorption, volume, and turbidity), color values, texture characteristics, sensory characteristics, and antioxidant activities. The weight, water absorption, and volume of cooked RLP noodles increased according to RLP content. The turbidity values of cooking water increased according to RLP content. The L value of RLP noodles decreased with increasing amounts of RLP, whereas a and b values increased with increasing amounts of RLP. The texture characteristics of RLP noodles decreased compared to those of control noodles except for adhesiveness. Antioxidative activities of RLP noodles significantly increased with increasing RLP content (P<0.05). The sensory preference test revealed that RLP 30% noodles showed the highest scores for smell, taste, chewiness, and overall preferences. It is suggested that RLP 30% noodles could be substituted for wheat flour to improve noodle quality.

  • The study was to investigate the quality of wet noodle added with the powder green tea. The wet noodles were prepared to the ratio of 1, 2, 3, 5, 7.5 and 10% (w/w) of the powder green tea based on a flour weight. The initial pasting temperature in an amylograph was increased as the increase of the powder green tea, while peak and final viscosity as the increase decreased. The weight and volume of cooked noodles were decreased, and turbidity of soup was increased with the addition of the powder green tea. L and a values of wet noodles were decreased with the addition of the powder green tea, and b value was increased. Texture profile analysis of cooked noodle showed a increase of hardness, cohesiveness, springiness, chewiness up to 2% powder green tea, but decreased from 3% power green tea. However, adhesiveness decreased as the increase of the powder green tea. From the sensory evaluation, the wet noodles included 1% powder green tea were similarly evaluated as the noodle used whole wheat flour.

  • An objective method for the evaluation of eating quality of cooked noodle was established by using a specially designed shear extrusion cell of Rheometer. From the force-distance curve, the maximum force, initial force, extrusion work, and the slope were determined. In a test with Korean dried noodles made from 17 types of Australian wheat flour, the maximum and initial forces and extrusion work could represent the firm-soft and chewy character, which govern mostly the preference of cooked noodle. On the other hand, the slope could distinguish the textural changes of cooked noodle during the storage after cooking. The parameters showed significant correlation with the protein content, water absorption, development time and extensibility of flour, but no correlation was obtained with the maximum viscosity of viscogram. For the estimation of textural preference, the correlation coefficient obtained from a multiple regression analysis using the maximum viscosity of viscogram and the maximum force of shear extrusion test as the two independent variables was not significantly higher than the coefficient obtained from a simple regression with the maximum force only.

  • Tetrasodium polyphosphate peroxidate (TPP) increased the farinograph stability, maximum resistance by extensigraph and amylograph peak viscosity of a noodle flour produced from Australian Standard White wheat (protein 8.76%, ash 0.380%) at concentration of $0.2{\sim}0.4%$ based on flour weight. The addition of 0.3% TPP increased the moisture content of Kalguksoo, handmade fresh noodle, by 1.5%. No significant differences however were observed in cooking properties. Sensory evaluation revealed that the color, texture and preference of cooked noodle were significantly better in the presence of TPP. The fresh noodle with 0.3%, TPP delayed the development off-flavor by 7 hr during storage at $20^{\circ}C$ and $25^{\circ}C$.

  • Sparassis latifolia is called "Cauliflower Mushroom" and is known as an edible mushroom that has high content of ${\beta}$-glucan. Recently, artificial cultivation of S. latifolia has been done by bottle, plastic bag and wood cultivation in Korea. However it is not widely used because there are low incubation ratio and yield. For the high efficiency of production, we aim to find the superior strains and media for better mycelial and fruit body growth. First, we analyzed the genetic relationship among 31 strains and divided five groups with three kinds of URP primers. And then ten strains were selected from five groups based on the experiment of mycelial growth. The suitability of media for mycelial growth was different according to media type. The suitable solid and liquid media for mycelial growth of S. latifolia isolates were PDA and M2, respectively. In addition, with regard to C/N ratio, the mycelial growth increased even until C/N 160. Second, we investigated the production of fruitbody of the strains by plastic bag cultivation. The substrate was mixed with larch sawdust, corn flour, and wheat flour (8:1:1, v/v). Moisture content of substrate was controlled by about 60% with 10% molasses solution. Out of 31 strains, 19 strains formed primordia. The eight strains produced more than 140g/1kg in fresh weight. Third, molasses culture media was selected for the mycelial growth. And molasses suitable sugar content and input aeration were around 8Brix% and 0.3~0.6vvm, respectively. The longer the incubation period is, the more dried weight of mycelia increased, but medium volume decreased. Therefore, the best incubation period was 9 to 11 days depending on strains. In the future, research project entitled development of culture system and new variety for stable production of S. latifolia will be considered as a new item.

  • Defatted soybean meal (DSM) was microparticulated at cut-off whell speed of 9.000 rpm and air-classified into fine and coarse fractions at air classifying wheel speeds (ACWS) of 21,000, 18,000, 15,000 12,000 and 9,000 rpm stepwisely. Protein and ash content increased while lipid, carbohydrates and dietary fiber content decreased with decreasing ACWS. Amino acid composition and amino acid content of defatted soybean meal were similar to those of raw soybeans with aspartic and glutamic acid, the major amino acids. The yield and particle size increased with decreasing ACWS and mean particle size ranged from $4.9{\mu}m$ to $14.2{\mu}m$. The particles were oval-shaped with sharp corners. Water holding capacity, oil holding capacity and emulsion capacity slightly decreased with decreasing ACWS. Soybean curds formed showed different characteristics depending on the coagulant used and on the substitution ratio of full fat soybean flour with microparticulated DSM. Microparticulated DSM could successfully substitute wheat flour up to 10% level without bring no-ticiable beany flavor in the cakes.

  • Rice bread premix was prepared from rice flour and vital wheat gluten, and the changes in the premix properties were studied during storage at 5, 25 and $35^{\circ}C$ for 4 months. Optimum level of 14-17% vital gluten could be added to the rice bread premix. The pH, sedimentation value, and Pelshenke value of the rice bread premix decreased with increasing storage period, whereas water retention capacity (WRC) and alkaline water retention capacity (AWRC) increased with increasing storage temperature. Mixograph peak time increased with increasing storage temperature. Rapid Visco Analyser (RVA) peak viscosity and setback values increased with increasing storage temperature and period. Decreased loaf volume was observed at the rice bread prepared from the premix during storage, especially at higher temperatures. Crumb hardness of the rice bread prepared from the premix increased during 4-month storage period.

  • The quality characteristics of yellow layer cakes produced by different methods of buckwheat powder addition (0, 10, 20, 30, 40) were investigated. The specific gravity of the dough increased as the amount of buckwheat powder added increased. Regarding the color of the crumb of cake, the L value and b value(yellowness) were lower as the amount of buckwheat powder added increased, but the a value(redness) increased. The cake volume tended to decrease as the amount of buckwheat powder added increased. The cake symmetry index and uniformity index were not significantly different from those of the control group, but the baking loss rate was slightly lower when buckwheat powder was added. The hardness was significantly higher than that of the control as the amount of buckwheat powder added increased. A sensory test showed that the taste had a high score when 20% buckwheat powder was added, and texture and overall acceptance were not significantly different from the control group until 20% buckwheat powder was added. Therefore, when a part of wheat flour is replaced with buckwheat powder to produce a yellow layer cake, it is possible to produce a product with improved cake quality and symbolic characteristics when a buckwheat powder 20% level is added.
