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.

Peroxide values increased rapidly for 21 days and then decreased. The acid and peroxide values were lower in peanut oil added with 50% sesame oil compared to peanut oil added with 30%, 10%, and 70% sesame oil, as well as the control. The TBA values of peanut oil made with 50% and 30% sesame oil were lower than those of the control and 70% and 10% sesame oil. According to the Rancimat method, PS-50% (524 min) and PS-30% (453 min) demonstrated longer induction periods as compared to the control (280 min), PS-70% (445 min), and PS-10% (291 min) samples.

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 promote the utilization of fish paste containing four different amounts (0%: control, 2, 4, and 6%) of cheonggukjang powder. For Hunter color values, L values of samples decreased as concentration of cheonggukjang powder increased, and a and b values increased. Folding tests for all samples showed good flexibility. In the texture meter test, hardness, cohesiveness, and springiness increased according to increasing concentrations of cheonggukjang powder. However, gumminess and brittleness of fish paste were reduced upon addition of cheonggukjang powder. In the sensory evaluation, fish paste prepared with 2% cheonggukjang powder was more preferred over other fish pastes. This study suggests that addition of 2% cheonggukjang powder to fish paste could be a good way to increase cheonggukjang powder without decreasing texture acceptability.
The purpose of this study was to investigate the effects of Curcuma aromatica powder on the functional and sensory characteristics of Mandupi. Various Mandupi samples were prepared with wheat flour along with addition of various amounts of Curcuma aromatica powder, after which instrumental characteristics and sensory evaluations were investigated. According to the amylograph data, the composite Curcuma aromatica powder-wheat flour samples showed increased gelatinization temperatures with increasing Curcuma aromatica powder content, whereas initial viscosity at 95oC, viscosity at 95oC after 15 minutes, and maximum viscosity were reduced. In terms of Hunter’s color values, L value decreased while a and b values increased with increasing Curcuma aromatica powder content. Besides cooked weight, cooked volume and turbidity of Mandupi increased as the addition level of Curcuma aromatica powder increased. In terms of textural characteristics, addition of Curcuma aromatica powder increased springiness, chewiness, and brittleness, whereas springiness and adhesiveness decreased. Based on sensory evaluations, the overall preference of Mandupi with 3% added Curcuma aromatica powder was higher than that of control.
The principal objective of this study was to evaluate quality characteristics of dried noodles when different concentrations of lotus leaf powder (LLP) were added to the wheat flour, thereby determining which noodle recipe was preferred. The cooking quality, mechanical texture properties, and viscosity were measured, and then a sensory evaluation was conducted with the prepared noodles. The gelatinization points of the composite LLP-wheat flours were shown to have an increased, viscosity at 95oC after 15 minutes. As measured via amylograph, the maximum viscosity values of those samples were decreased as the LLP content was increased. As well, when increased amounts of LLP were added, both the L and a values were reduced, whereas the b value was increased. The color values, weight and volume of the cooked noodle increased, as did the turbidity of the soup. With regard to the textural characteristics, the LLP additive increased hardness and cohesiveness, and reduced adhesiveness and springiness. Overall, according to the results of our sensory evaluation, the noodles prepared with 5% LLP were preferred over the other noodles.

The L value decreased as the amount of LLP in the formulation increased, whereas the a and b values of the tofu increased. Furthermore, the hardness, chewiness, and brittleness significantly increased as the level of LLP increased. In terms of overall acceptability, the preferred tofu samples contained 0.5% LLP. These results suggest that the LLP can be applied to tofu (soybean curd) in order to achieve high quality and functionality.
The quality characteristics of yenipsambab prepared using various amounts of red, green, and black pigmented rice (0, 10, 20, and 30% added) were investigated. The pH of the cooked rice of yenipsambab decreased significantly as the amounts of pigmented rice increased. The Hunter’s color L value decreased, but the b value increased with increasing amounts of pigmented rice. Moreover, the addition of 10-30% pigmented rice resulted in increased hardness, adhesiveness, cohesiveness, springiness, chewiness, and brittleness compared to the control. Finally, the results of the sensory evaluation and acceptance test showed that the cooked rice containing 10-20% pigmented rice had the highest scores. This study will help in the development of new rice products that are good for the health.
