  • Meat provides high quality proteins, lipids, minerals and vitamins. The meat protein is especially high in essential amino acids that are crucial for human health, growth & development and for the formation of enzymes, hormones and antibodies. Relatively cheap and nutritionally sound vegetable proteins that are similar to animal proteins are being developed to replace the animal proteins in texture, nutrition and food characteristics. In this study a nutritionally sound meat lipid replacing food Oatrim that has been produced by converting oat starch into maltodextrin by ${\alpha}$-amylase, have been partially substituted for beef and general component analysis, texture measurement and sensory tests have been conducted. The results are 1. Water content of the non-treated (0% treated) was 67.1% and the treated (10% treated) was 77%. The treated showed better water holding capacity. 2. Protein content of the non-treated was 21.2 g/100 g; the 4% treated, 18.4 g/100 g; the 6% treated, 18.2 g/100 g; the 8% treated, 17.2 g/100g; and the 10% treated, 16.0 g/100 g. The protein content tended significant. 3. Amino acid analysis results showed that glutamic acid content was the highest in Oatrim and as its amino acid make up is exellent, it is valuable as a fine low fat protein food. 4. Sensory tests show that the increased Oatrim content increased the appearance quality but food characteristics were high only in the 4% and 6% treated groups, indicating that the replacement ratio should not exceed 10%. 5. Texture measurement analysis results show that the higher the replacement content, lower the springness, cohesiveness, hardness, chewiness and gumminess, resulting in relatively soft overall texture. However, in order to better the food characteristics, more studies must be continuously done, and so by being able to increase vegetable substitution over meat, it may be able to contribute to the prevention of adult disease.

  • Glutinous rice dduk, traditional Korean rice cake, was prepared using rice(white glutinous rice, brown glutinous rice, black glutinous rice, gaba glutinous rice) as a meal alternative, and each of their quality characteristics were compared. This study had checked sensory tests, color differences, moisture contents, texture characteristics, and storage lives of dduk during storage at room temperature for 6 days. The moisture contents of black glutinous rice dduk scored the highest. For color properties, gaba glutinous rice dduk was darker with a decreased yellow value, whereas its red value was higher comparing with that of brown glutinous rice dduk. The results of the preference test showed that appearance, flavor, texture, and overall preference were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the lowest score. The results of the color difference test showed that softness, viscoelasticity, and fineness were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the highest difference in color. For individual textural characteristics, black glutinous rice dduk showed the highest score, whereas white glutinous rice dduk showed the lowest scores in hardness, chewiness, and gumminess. In the results of the textural characteristics of dduk during storage, white glutinous rice dduk showed the highest increase in hardness after 48 hours, whereas black glutinous rice dduk showed the lowest increase. White glutinous rice dduk showed the highest increases in chewiness and gumminess. Cohesiveness decreased in all glutinous rice dduk. In the results of fungal occurrence in dduk during storage, black and gaba glutinous rice dduk showed increased fungi occurrence compared with white and brown glutinous rice dduk after 6 days. In conclusion, the overall preference for glutinous rice dduk made from different rice is more affected by appearance or texture than flavor.

  • This study tried to investigate the best mixing ratio by reviewing the quality characteristics such as moisture content, chromaticity and texture, and sensory characteristics of Seolgidduk made of different ratios of persimmon extracts. A and b color values appeared to increase and L value (lightness) to decrease according to the increase of persimmon extracts ratio. In the case of texture, hardness, adhesiveness, springiness, cohesiveness, gumminess and chewiness increased according to the increase of added amount of dried persimmon extracts. The inside section of Seolgidduk was investigated through scanning electron microphotograph, and the $15\%$ of dried persimmon extracts had the smallest and uniform air cells. Seolgidduk with $15\%$ persimmon extracts showed the highest color, flavor and chewiness scores of 3.85, 3.65, and 3.80 from sensory evaluation, respectively. The moistness displayed significant differences according to the increment of the extract Seolgidduk with $15\%$ persimmon extracts displayed the highest overall acceptability of 3.95, while that of the control 3.10. From the above results, $15\%$ mixing ratio of dried persimmons extracts seems to be the most desirable for making Seolgidduk.

  • 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 -$10^{\circ}C$.

  • The quality characteristics of bread prepared with the addition of dried persimmon peel powder(PPP) were investigated. Visco-elastic characteristics of dough and texture of bread added PPP was examined by rapid visco-analyzer and texture analyzer. The maximum viscosity of the dough with PPP was lower than that of control at 90$\^{C}$. Final viscosity after cooling to 50$\^{C}$, viscosity of control increased to 134 B.U., but that of the dough with PPP showed 13∼37 B.U. As more PPP was added, gluten formation and mixing time dough were longer. Adhesiveness, springness, cohesiveness and chewiness gradually increased as PPP content increased, while the hardness decreased. Lightness value decreased but redness and yellowness values increased with the addition of PPP, especially, the bread made by 15% PPP treatment showed dark brown color. In sensory evaluation of bread, score of color decreased significantly as more PPP was added but overall acceptability was not significant different(p<0.05) between control and 5% PPP treatment. It is considered that the addition of 5% was appropriate for bread making with PPP.

  • This study was conducted to investigate the noodle added with Pachyrhizus erosus powder. Total contents of carbohydrates, crude protein, crude lipid, ash, and total dietary fiber were 87.14%, 3.14%, 0.81%, 7.82%, and 49.12%, respectively. The water-binding capacity was significantly increased by increasing amount of the Pachyrhizus erosus powder. When the volume of the noodles was measured after cooking, there was no difference between the control and Pachyrhizus erosus powder groups. The texture characteristics of hardness increased by increasing amount of the Pachyrhizus erosus powder. As a result of the sensory test, the 1.5% Pachyrhizus erosus powder noodles showed the highest scores for all items including appearance, flavor, taste, texture and overall acceptability. The bacterial counts of noodle decreased with greater Pachyrhizus erosus powder content on the third days. It is considered that research on antimicrobial activity should proceed in the future. As a result, it was finally suggested that optimum level of the Pachyrhizus erosus powder in the product was 1.5% level.
