  • Physicochemical and microbiological properties of red beans, soybeans, barleys, and corns irradiated by gamma-ray at 1.2 kGy, 10.1 kGy, or 30.5 kGy were investigated. Moisture content and crude lipid content of the irradiated cereals showed no significant difference from the nonirradiated group. TBA values of corns irradiated at 30.5 kGy increased. Gamma irradiation reduced the numbers of mesophilic and psychrotrophic bacteria in the cereals. Yeasts and molds were reduced below detection levels even at 1.2 kGy dose-irradiation. There was no significant difference in reducing sugars between the irradiated cereals and the nonirradiated ones except corns. Stachyose, raffinose, and sucrose of soy beans and sucrose of barleys increased by 30.5 kGy dose-irradiation. Loss of riboflavin content of the irradiated samples was not observed except red beans irradiated at 30.5 kGy. In Hunter's color, b value of the red bean powder increased but L value of the soybean powder decreased by the Irradiation. L, a, and b values of the barley powder slightly increased under 30.5 kGy dose-irradiation and b value of the corn powder decreased under 10.1 or 30.5 kGy-dose irradiation.

  • The characteristics of Jeungpyun were investigated with different milling methods of rice flour. The moisture content of Jeungpyun was similar to that of the rice flours. In the color of Jeungpyun, L-value was increasing but a and b-value were decreasing as its moisture content was increasing. The analysis on the texture of Jeungpyun showed that Jeungpyun by dry milling indicated the higher value in hardness and the lower value in springiness, cohesiveness and chewiness than Jeungpyun by wet milling. The test of the sensory characteristics for Jeungpyun showed that whiteness, moistness, springiness and chewiness was higher for Jeungpyun by wet milling. But the softness was lower. Overallquality of Jeungpyun by wet milling was higher than Jeungpyun by dry milling. Generally, Jeungpyun prepared by Pin-mill was the best in quality. In particular, Jeungpyun by wet milling was better for the added 80% of water and Jeungpyun by dry milling was better for the added 100% of water.

  • This study was carried out to investigate the quality characteristics of Jeung-Pyun with respect to the addition ratio of pigmented rice and fermentation method. As the mont of pigmented rice was increased, the moisture content of the products added with yeast tended to increase more than those made in the traditional way. Regardless of fermentation method, L value and b value of Jeung-Pyun without pigmented rice were higher than those of Jeung-Pyun with pigmented rice, for which the values were significantly low. The samples with 5% or 10% pigmented rice had a high degree of expansion. The other samples showed no visible difference. The hardness, cohesiveness, springiness and chewiness tended to decrease. On the other hand, the adhesiveness was increased. In both fermentation methods, as the amount of pigmented rice was increased, the gelatinization degree was raised. In sensory evaluation, the characteristics of Jeung-Pyun with 30% pigmented rice were very poor, except for the characteristics on pore uniformity. The other samples and both fermentation methods were hardly different.

  • This study was performed to examine the optimum addition amount of saltwort(Salicornia herbacea L.) powder to rice flour in the preparation of saltwort Sulgidduk. Saltwort powder was added to rice powder at ratios of 5, 10, 15 and 20%(w/w). The moisture contents of Sulgidduk were increased with the addition of saltwort powder. The pH contents of Sulgidduk were decreased with the addition of saltwort powder. The incorporation of saltwort powder in Sulgidduk lowered the lightness but increased the redness values. Mineral contents of Sulgidduk were increased with the addition of saltwort powder. The hardness and brittleness were decreased, whereas cohesiveness was increased with the addition of saltwort powder. In the sensory evaluation of saltwort Sulgidduk, the acceptance of flavor, taste, chewiness and overall acceptability characteristics was the highest at the 5% level. Saltwort Sulgidduk, with the addition of 5% of saltwort powder to rice flour was found to be the best recipe in terms of the sensory qualities.

  • 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.
