  • To establish an optimum formula for processing wet noodles with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5, 10 and 20% based on a flour weight. Application of 2% mehthylcelluose(MC) to improve the texture of noodles mixed with SHF was also attempted. Evaluation was performed on the dough rheology and wet noodle quality, such as cooking characteristics, mechanical texture properties, sensory value and shelf-life. Water absorption rate of the composite flour increased linearly as the content of SHF increased from 1% to 10%, and noodle sheet-formation was also acceptable in the same content level. The weight and volume of cooked noodles were decreased, and turbidity of soup was, if exceeding more than 5% of SHF, increased constantly. However, these problems could be remarkably resolved in SHF plus 2% MC. Texture profile analysis of cooked noodles showed an increase of hardness, gumminess, and chewiness up to 5% SHF. The results of sensory evaluation showed that cooked noodles containing 5% SDF were acceptable as much as wheat four noodles in terms of color, texture, taste and flavor. Based on cooking properties, rheological and sensory evaluation, addition of 5% SHF plus 2% MC was suggested to be suitable for making wet noodles, of which the shelf-life was estimated to be 8 days at $5^{\circ}C$.

  • The purpose of this research was to improve the quality of Sulgidduk by additions of green tea or rosemary powder to enhance its functional properties and antimicrobial effects. The green tea or rosemary powders were added to the Sulgidduk at different levels (1 or 3%), and color values, textural characteristics, sensory qualities, pH values, and acetic acid values were evaluated. With higher amounts of green tea or rosemary powder, the L-values of samples decreased and a-and b-values increased. Texture profile analyses indicated that hardness was significantly different among all the samples. The sensory evaluation results showed that the 1% addition of green tea or rosemary powder did not cause significant differences in overall acceptability, flavor, or taste. During storage, pH values decreased in all groups and the control group showed the lowest value. Acetic acid values increased during storage and the control group showed the highest value in the last stage of storage. Finally, the L- and a-values of samples did not change significantly during storage.

  • This study was performed to examine the quality characteristics of red ginseng wet noodles prepared with additions of carrageenan, xanthan gum, or guar gum. The quality characteristics of the samples were estimated in terms of their general composition, color differences, cooking characteristics, textural attributes, sensory qualities, and microbial growth during storage. The results were as follows. Protein content was significantly decreased in the guar gum added group and ash content was significantly increased in the carrageenan added group (p<0.05). Lipid, water, and Na contents were not significant different among the groups. However, water binding capacity was significantly increased in the group with added xanthan gum. Over 10 weeks of storage, water contents did not differ significantly between the xanthan gum and guar gum added groups. In all the added gum groups, L- and a- values were significantly increased whereas b- values decreased (p<0.05). In texture profile analyses, chewiness, cohesiveness, hardness, and springiness were significantly increased in the carrageenan and xanthan gum added groups (p<0.05). According to sensory evaluations, surface color, red ginseng flavor, red ginseng taste, softness, chewiness, and overall acceptability were considered very good in the xanthan gum and guar gum added groups (p<0.05). Therefore, the red ginseng noodles containing xanthan gum and guar gum were deemed most preferable and presented the safest shelf-life during 10 weeks at -$10^{\circ}C$.

  • While attempting to develop low salt, low fat and high fibre chicken nuggets, the effect of partial (40%) common salt substitution and incorporation of chickpea hull flour (CHF) at three different levels viz., 5, 7.5 and 10% (Treatments) in pre-standardized low fat chicken nuggets (Control) were observed. Common salt replacement with salt substitute blend led to a significant decrease in pH, emulsion stability, moisture, ash, hardness, cohesiveness, gumminess and chewiness values while incorporation of CHF in low salt, low fat products resulted in decreased emulsion stability, cooking yield, moisture, protein, ash, color values, however dietary fibre and textural properties were increased (p<0.01). Lipid profile revealed a decrease in total cholesterol and glycolipid contents with the incorporation of CHF (p<0.01). All the sensory attributes except appearance and flavor, remained unaffected with salt replacement, while addition of CHF resulted in lower sensory scores (p<0.01). Among low salt, low fat chicken nuggets with CHF, incorporation CHF at 5% level was found optimum having sensory ratings close to very good. Thus most acceptable low salt, low fat and high fibre chicken nuggets could be developed by a salt replacement blend and addition of 5% CHF.

  • The seaweed Hizikia fusiformis is rich in protein, carbohydrates, vitamins, and minerals. We investigated the physicochemical properties and antioxidant activities of yanggaeng made with agar, sugar, honey, oligosaccharide, cooked white bean paste, and different amounts (0, 1, 2, 3, 4, and 5%) of H. fusiformis powder. The proximate composition, pH, sugar content, color, texture, antioxidant activity, and sensory properties of the yanggaeng were investigated. The moisture and sugar contents of the yanggaeng did not change despite increasing the amount of H. fusiformis. The pH decreased with increasing H. fusiformis. The lightness decreased significantly, whereas the redness and yellowness increased with increasing amounts of H. fusiformis. In the texture profile analysis, the hardness, gumminess, and chewiness decreased with increasing H. fusiformis content. The antioxidant activity of the yanggaeng increased with the concentration of the H. fusiformis powder. The yanggaeng containing 2% H. fusiformis had the highest overall sensory acceptance score. The addition of H. fusiformis to yanggaeng appears to improve its quality and antioxidant activity.

  • To develop functionally and nutritionally improved whole soybean curd (WSC), the effects of partial (0~4%) replacement with pine needle powder (PNP) on the quality characteristics of WSC were investigated. The moisture content and pH ranged from 76.96~77.80% (wet basis) and 6.69~6.74, respectively, with no considerable differences. Lightness significantly decreased with higher PNP content in the formulation (P<0.05), as indicated by visual observation that the color of WSC became darker. Redness and yellowness also significantly decreased (P<0.05). The texture profile analysis indicated that WSC containing PNP was softer and less cohesive than control WSC. 2,2-Diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radical scavenging activities significantly increased (P<0.05) with higher substitution of PNP, and they were well correlated. Results from the consumer test revealed that WSC with 1% PLP received the most favorable acceptance scores for sensory attributes, including overall acceptability. The present study indicated that the characteristics of PNP may play a role in improving WSC quality in terms of physicochemical, sensorial, and antioxidant characteristics.

  • This study was performed to investigate the quality characteristics of Yakpyun with added brown rice. The Yakpyun was prepared with polished rice, brown rice, Jujube paste, Makkolli, sugar and salt. The Yakpyun was made with various levels (0, 20, 40, 60 or 80%) of added brown rice. After making the Yakpyun, it was examined for the effect of adding brown rice on quality characteristics using scanning electron microscopy (SEM), a mechanical test, and a sensory evaluation. The moisture contents of Yakpyun tended to decrease with increasing amounts of added brown rice, but no significant differences were observed. As the content of brown rice increased, the lightness (L) decreased and redness (a) and yellowness (b) increased. In a texture profile analysis, hardness decreased with increasing brown rice content from the moment of production to 3 days of storage. When more brown rice was added, rough surfaces were found more often under SEM, and large holes were evident between granules. The results of the sensory evaluation showed that overall acceptability was the highest for Yakpyun containing 40% added brown rice.

  • The noodle is one of the most popular meal as a main dish in Korea and onions are reported to contain high levels of flavonoids such as quercetin, aglycone, and quercetin 4-glycoside. This study was conducted to develop the wet noodle with onion juice and to examine the cooking quality, textural properties of it. Five sensory attributes such as gloss, chewiness, adhesiveness, odor, and taste were used for sensory evaluations. Optimal amount of onion(149.5 g) and salt (6.5 g) satisfied target sensory score(7.0) was suggested by response surface methodology. The wet noodle with optimal amount of onion juice and salt was tasted by 100 consumer and showed high score(6.67) in overall acceptability. Cooking quality was measured through absorption of water, volume, degree of turbidity. The volume, water absorption, and cooking water turbidity of cooked wet noodle with onion juice(experimental noodle) were significantly(p<0.01) higher than the control one. Texture profile analysis of experimental noodle showed a lower score of hardness, adhesiveness, springiness, and chewiness. However, it appeared that the experimental noodle showed higher score for cohesiveness than the control noodle.

  • This study examined the quality characteristics of noodles prepared with Pleurotus (P.) eryngii paste. Different ratios of P. eryngii paste were added to wheat flour(15%, 30%, and 45%) in the noodle formation. Then, the noodles were evaluated in terms of their cooking, color, texture properties, and sensory properties. The weight and water absorption of the cooked noodles increased with increasing P. eryngii paste content, but the turbidity of cooking water decreased. According to texture profile analyses both the cooked and uncooked and cooked noodles had significant increases in springiness and cohesiveness with the addition of P. eryngii paste. And when compared to the control, hardness and gumminess were significantly lower in the samples containing P. eryngii paste. The lightness, redness, and yellowness of the cooked and uncooked noodles increased with increasing with increasing P. eryngii paste content. Finally sensory evaluation results indicated that the noddles containing 30% and 45% P. eryngii paste had higher quality as compared to the other samples. Overall the results suggest that P. eryngii paste is effective for improving the texture and quality of noodles.
