  • The objective of this study was to determine the characteristics of noodle dough made with biji powder (2, 4, 6 and 8%). Increase in the amount of biji powder significantly increases the water-binding capacity and decreases lightness (L) (p<0.05). The changes of redness (a), yellowness (b) and size of pore were insignificant. In the case of raw noodle, hardness, springiness, gumminess and chewiness of raw noodle significantly increased with increasing concentrations of the biji powder (p<0.05). Hardness of cooked noodle increased according with increase in concentration of biji (p<0.05). Springiness was increased up to 4% of biji concentration and slightly decreased at higher concentrations (p<0.05). Adhesiveness and cohesiveness of cooked noodle decreased according with increase in concentration of biji (p<0.05). The was no significant changes in the gumminess and chewiness. Taken together, addition of 4.0% biji powder to noodle dough may improve the preference of noodles.

  • The effects of storage form (paddy and milled rice) and storage period (1, 2, and 3 years) of rice at low temperature $(4^{\circ}C)$ on physicochemical properties of milled and cooked rice and sensory characteristics of cooked rice were investigated. The proximate compositions except moisture content of rice decreased as the storage period increased. Water binding capacity, solubility and swelling power of rice flour decreased with the extended storage period. In the amylogram, the initial pasting temperature, paste viscosity and breakdown of paddy rice flour slurry decreased after 2 years of storage. Moisture content of cooked rice increased while the amount of water evaporated during cooking decreased. These trends were obvious with the longer storage period. Lightness and yellowness of cooked rice were greatly changed after 3 years of storage, regardless of storage form. Texture profile analysis of cooked rice by Texture Analyzer revealed that hardness, fracturability, gumminess were gradually increased while adhesiveness decreased as the storage period of rice increased. A trained panel found that color intensity, intactness of grains, rancid flavor, rice bran flavor, wet cardboard flavor, hardness and chewiness of cooked rice increased with the longer storage period. However, glossiness, transparency, plumpness, puffed corn flavor, dairy flavor, boiled egg white flavor, sweet taste, adhesiveness to lips, smoothness and inner moisture decreased with the extended storage period up to 3 years. Instrumental hardness was highly correlated with sensory hardness.

  • Nutritional compositions of the raw materials, such as well-milled rice, milled upland glutinous rice, milled barley, glutinous millet, SoRiTae, red beans and mung beans were analysed, and cooking characteristics and sensory attributes of mixed cereals were measured. Crude protein and crude fat in SoRiTae were 31.6% and 16.16%, respectively, and the highest among the raw materials. Crude ash was 3~11 times higher and crude fiber was 5~7 times higher in legumes than in grains. Iron content in SoRiTae was the highest as 7.8 mg/100 g, and calcium content was the highest as 71.0 mg/100 g in SoRiTae and mung beans. Phosphorus content was higher in glutinous millet and mung beans, and potassium content was greatly higher in legumes than in grains and the highest as 934 mg/100 g in red beans. Vitamin B$_1$ and B$_2$ contents were higher in legumes than in grains, and niacin content was the highest as 5.51 mg/100 g in mung beans and was 3.77 mg/100 g in glutinous millet. Water uptake of the raw materials increased greatly after 5 min of soaking in water and then stayed at the almost same level. Water uptake was the highest in SoRiTae and decreased in the order of milled barley, milled upland glutinous rice, glutinous millet and well-milled rice. Hardness was the lowest as 142.8 g/cm$^2$ in cooked SoRiTae, and the highest as 206.3 g/cm$^2$ in cooked milled barley compared with 169.4 g/cm$^2$ in cooked well-milled rice. Cooking time increased and hardness of cooked mixed cereals decreased with the increase of water added. Moisture content decreased, while crude protein, crude ash and crude fiber increased as the increase of mixing ratio of SoRiTae and red beans in mixed cereals. Lightness decreased, while red and blue color increased, and hardness increased with the increase of mixing ratio of SoRiTae and red beans. Sensory evaluation showed greater preference in terms of color, roasted nutty, sweet taste and overall acceptance in the cooked mixed cereals with 8 and 10% of SoRiTae and red beans.

  • This study was carried out to analyze the antioxidant components and activities of cooked mixed grain rice-added foxtail millet with different addition rates (5, 10, 15, and 20%) and cooking methods. The two foxtail millet varieties used in this study were non-waxy foxtail millet, 'Samdame', and waxy foxtail millet, 'Samdachal'. Cooked mixed grain rice-added foxtail millet was cooked by general and high pressure cooking methods with and without fermented alcohol. Except for breakdown viscosity, pasting characteristics of foxtail millet were reduced with increasing amounts of foxtail millet. Water-binding capacity and swelling power significantly decreased with increasing amounts of foxtail millet, whereas water solubility index significantly increased. Total polyphenol and flavonoid contents increased with increasing amounts of foxtail millet. DPPH and ABTS radical scavenging activities also increased with increasing amounts of foxtail millet. Moreover, foxtail millet cooked by general cooking method with fermented alcohol showed higher antioxidant effect compared to other cooking methods. In this study, antioxidant components and activities of cooked mixed grain rice-added foxtail millet with different addition rates and cooking methods can be used as basic data for manufacturing processed products.

  • The objective of this study was to determine the physicochemical and sensory properties of cooked emulsion sausages containing different levels of lotus rhizome powder (0, 1, 2, and 3%, based on total weight). Lotus rhizome powder had no significant (p>0.05) impact on pH, moisture, protein, or ash content of sausage. However, fat content was slightly but significantly (p<0.05) decreased when the level of lotus rhizome powder was increased in the sausages. The addition of lotus rhizome powder to sausages at over 1% resulted in significantly (p<0.05) darker and less red color of cooked sausage compared to control. Increase in lotus rhizome level slightly improved the emulsion stability and apparent viscosity. Significant (p<0.05) reduction in cooking loss was observed when more than 1% of lotus rhizome powder was added to sausages. The textural properties of sausages were unaffected by the inclusion of lotus rhizome except for springiness and chewiness. On the manufacture day, control sausage had significantly (p<0.05) higher TBARS value than treatments. Regarding sensory characteristics, increased levels of lotus rhizome powder decreased (p<0.05) color and juiciness scores. However, cooked sausages exhibited similar overall acceptability regardless of the level of lotus rhizome powder added to sausages. Therefore, lotus rhizome powder, an antioxidant dietary fiber, could be used as an effective natural ingredient in meat products for the development of healthier and functional food.

  • The noodle making characteristics were investigated for both eleven varities of Korean wheat, such as Chokwangmil, Geurumil, Eunpamil, Tnpdongmil, Woorimil, Oigeurmil, Alchanmil, Cobunmil, Geumgangmil, Seodunmil and Suwon 265, and two varieties of imported wheat, DNS(Dark Northern Spring Wheat) and ASW(Australian Standard White). After cooking of dry-noodle, the elasticities were 0.59-0.79 in the native wheat and 0.55-0.57 in the imported wheat. Among the varieties showing the highest value in the various texture properties of cooked dry-noodle, Alchanmil was highest in gumminess, Geungangmil in cohesiveness, Olgeurumil in adhesiveness, Geurumil in fimmess, Chokwang in chewiness, Tapdongmil in tensile strength Gobunmil in breaking strength. After cooking the wet-noodle, Tapdongmil in elasticity, Geurumil in adhesiveness, Geumgangmil in gumminess, cohesiveness, firmness and chewiness, and Suwon 265 in tensile strength showed the highest values in the respective textural properties. From the sensory evaluation of the cooked dry-noodle, the significant differences (p<0.05) among wheat varieties were observed in color, texture and overall quality. As a result, ASW was excellent in our all qualities of cooked dry-noodle followed by Tapdongmil, Alchanmil and Geumgangmil. The cooked wet-noodle also showed the high sensory scores (p<0.01) were showing the best in Tapdongmil, followed by Eunpamil, Geumgangmil and Woorimil.

  • The ways of preservation of chotkal which are classified by the principles of fermentation, are analyzed and interpreted. Chotkal is preserved mainly as two forms; one is chot and the other is shikhae. The fact that shikhae is preserved only in the eastern area can be attributed to two main reasons; (1) raw materials are available throughout four seasons and (2) relatively less production of salt. Chotkal is further classified into nine different ways of preservation and shikhae into fourteen. Regional characteristics for chot include that (1) in western part, Kechot is preserved in salty water (2) in central part Origuljot is fermented either with salt and powdered red pepper, or with salt, powdered red pepper and cooked cereal, (3) in southern part, freshwater shrimp with (1) salt only, (2) salt and powdered red pepper, (3) salt and cooked cereal, (4) salt, powdered red pepper and cooked cereal, (4) in northern part, fish with salt and powdered red pepper. Those for shikhae include that malt is used in southern part, shredded radish in northern part and cooked cereal more in southern part than in northern part.

  • The effects of germinated brown rice flour on the quality characteristics of white wheat flour noodles were investigated. The insoluble dietary fiber and soluble dietary fiber content of germinated brown rice flour were 5.1% and 4.2%, respectively. Water absorption, development time, and stability of farinogram decreased when germinated brown rice flour was added to white wheat flour. Brightness ($L^*$) decreased, but redness ($a^*$) increased in noodles made from germinated brown rice. Volume of cooked noodles did not change upon addition of germinated brown rice flour, but weight of cooked noodles decreased and the turbidity of cooked water increased. The cutting force of cooked noodles did not change upon addition of germinated rice flour. Addition of 10% germinated brown rice flour to white wheat flour did not have any effects on flavor, color, taste, appearance, and overall acceptability in sensory evaluation.
