This study evaluated the quality characteristics of wet noodles added with sword bean powder(0, 5, 10, 15%) to determine the most preferred noodle recipe for consumer’s desire. The proximate composition of the sword bean powder was as follows: Moisture contents were 13.4±0.08%, protein 30.2±0.12%, fat 0.3±0.09%, protein 1.0±0.11% and carbohydrates 55.1±0.12%, respectively. Total amino acid content of sword bean powder was measured 23,054.266 mg/ 100 g, especially in the order of histidine, glutamic acid and aspartic acid. The flavonoid content of sword bean powder was 17.9750 mg%. Water-binding capacity increased as the level of sword bean powder increased. When viscosity of wheat flours containing sword bean powder was measured by amylograph, the gelatinization point increased significantly as the level of sword bean powder increased, but peak viscosity decreased. As the level of sword bean powder increased, L value decreased, whereas a and b values increased. Weight, water absorption and volume of cooked noodles prepared with wheat flours containing sword bean powder decreased, whereas turbidity of soup increased. For textural properties, addition of sword bean powder increased hardness, springiness, chewiness of cooked noodles, whereas adhesiveness decreased. According to sensory evaluation such as appearance, color, flavor, taste, texture, overall preference, it was revealed noodles with 10% sword bean powder was the most preferred. According to the results, the addition of sword bean powder positively affects the overall sensory evaluation of wet noodle, and 10% is the optimal level for addition.

This study evaluated the quality characteristics of semi-dried noodles prepared with different water contents (wet noodles; 32, 24, 22, 20%, dry noodles; 12%). The drying process was carried out in a drying chamber at 13~18oC temperature and 75~95% humidity. The proximate composition of Korean wheat flour was as follows: water 22.1±3.64%, protein 8.6±0.13%, fat 1.3±0.10%, ash 0.7±0.02%, carbohydrates 67.3±0.10%. As water contents decreased, both L and b values significantly decreased before cooking of noodles, whereas L, a, and b values were not significantly different after cooking of noodles. Weight, water absorption, and volume of cooked noodles significantly increased as water content decreased, whereas turbidity of soup was not significantly different. Cutting hardness before cooking of noodles significantly increased as water content decreased. Sections of noodles after cooking by SEM (scanning electron microscopy) showed roughness and fewer round starch particles as water content decreased. For overall preferences according to the sensory evaluation, noodles prepared with different water contents were not significantly different. According to the results, semidried noodles have development potential to complement the disadvantages of both wet noodles and dry noodles.

This study evaluated the quality characteristics of dried noodles prepared with doenjang powder (0, 3, 6, 9%) in order to determine the most preferred noodle recipe. The proximate composition of the composite doenjang powder-wheat flours was as follows: calories 365 kcal, carbohydrates 79 g, saccharides 3 g, protein 10 g, fat 0.8 g, and sodium 65 mg. As the level of doenjang powder increased, the content of total amino acids increased; aspartic acid, glutamic acid, tyrosine, and lysine contents increased, in particular. Water-binding capacity decreased as the level of doenjang powder increased. When viscosity of composite doenjang powder-wheat flours was measured by amylography, gelatinization point increased as the level of doenjang powder increased. As the level of doenjang powder increased, L value decreased, whereas a and b values increased. Weight, water absorption, and volume of cooked noodles decreased, whereas turbidity of soup increased. For textural properties, hardness decreased, whereas springiness increased as the level of doenjang powder increased. For overall preference according to the results of sensory evaluation, noodles added with 3% doenjang powder were the most preferred. According to the results, addition of doenjang powder positively affects the overall sensory evaluation of dried noodle, and 3% is the optimal level for addition.

This study evaluated the quality characteristics of dried noodles prepared with strawberry powder in order to determine the most preferred noodle recipe for children’s school meals. The proximate composition of strawberry powder used was as follows: moisture, 3.39%; crude protein, 1.53%; crude lipid, 0.97%; crude ash, 0.82%; and carbohydrates, 93.29%. When viscosity of the composite strawberry powder-wheat flours was measured by amylograph. Gelatinization point, maximum viscosity, viscosity at 95oC and viscosity at 95oC after 15 min decreased as the level of strawberry powder increased. As the level of strawberry powder increased, both L and b color values decreased, whereas a value increased. Weight, water absorption and volume of cooked noodles decreased, whereas turbidity of soup increased. For textural properties, addition of strawberry powder to cooked noodles reduced hardness, chewiness and brittleness. Overall preference according to the results of the sensory evaluation, noodles added with 6% strawberry powder were the most preferred. According to the results, the addition of strawberry powder can positively affect the overall sensory evaluation of dried noodles, and 6% is the optimal level for addition.

The study was conducted to evaluate the effects of Hericium erinaceum Powder (HEP) on the quality characteristics of Jook. The proximate composition of HEP was as follows: moisture, 6.10%; crude protein, 32.69%; crude lipid, 4.63%; crude ash, 11.40%; and carbohydrates, 45.18%. Each sample contained 3, 6, and 9% Jook of Hericium erinaceum Powder (JHEP) compared to the control and their physicochemical properties assessed. As the level of HEP increased, there was a significant decrease in pH (p<0.05) and significant increase in total acidity (p<0.001). In addition, L and a values decreased, whereas b value increased with increasing addition of HEP. The Jook showed lower spreadability and higher viscosity values as its content increased. According to the results, addition of HEP positively affects the quality characteristics of Jook.

This study was conducted to investigate the quality characteristics of tofu prepared with different concentrations of lotus leaf powder. The determined values for moisture, crude ash, carbohydrate, crude protein, and crude lipid in were 2.97%, 8.09%, 65.18%, 22.83%, and 0.93%, respectively. The yield rates of the tofu samples did not differ significantly according to the level of added lotus leaf powder; however, there was a significant decrease in pH and a significant increase in acidity. The L- and a-values of samples decreased as the amount of lotus leaf powder in the formulation increased, whereas the b value increased. Furthermore, hardness significantly increased as the level of lotus leaf powder increased. In terms of overall acceptability, the preferred tofu samples were the control and that containing 0.2% lotus leaf powder.
