  • This study examined the quality characteristics of Gondre tofu containing 0, 0.1, 0.2, and 0.3% Cirsium setidens powder. Quality and sensory tests of Gondre tofu were performed. The yield rate of tofu decreased with the addition of Cirsium setidens powder. The pH of tofu decreased after the addition of Cirsium setidens powder. During 8 days storage, the addition of Cirsium setidens powder to tofu did not effectively inhibit the number of total aerobic bacteria. The L, a and b values of tofu decreased with increasing amount of Cirsium setidens powder added. In the texture properties, the hardness, cohesiveness, gumminess and brittleness increased, whereas the springiness decreased. The results of sensory evaluation showed that tofu containing 0, 0.1, and 0.2% Cirsium setidens powder had a higher taste, texture preference and overall acceptability than 0.3% Cirsium setidens powder. Therefore, the addition up to 0.2% Cirsium setidens powder positively affects the sensory evaluation of Gondre tofu. The addition 0.2% Cirsium setidens powder might be considered the most appropriate choice for manufacturing Gondre tofu.

  • The aim of this study was to evaluate the effect of three different strains of lactic acid bacteria (LAB) starter cultures: Pediococcus pentosaceus (KC-13100) (PP), Lactobacillus plantarum (KCTC-21004) (LP1), and L. plantarum (KCTC-13093) (LP2) on the physicochemical and microbiological characteristics, and sensory quality of dry fermented sausages after 21 days of drying and ripening period. Treatments added with PP and LP2 strains showed a significant higher (p<0.05) LAB and total plat counts, and water activity (aw) of all three treatments was below 0.85 after the completion of the ripening process. A significant variation (p<0.05) in pH values of treatments was exhibited due to the difference in acidification capacity of the LAB strains: LP2PP>LP2. Substantial variations (p<0.05) in shear force values were detected amongst three batches (LP2>LP1>PP). In sensory attributes, PP treated samples had significantly higher (p<0.05) color and overall acceptability scores. The current findings proved how important the optimal assortment of starter culture. Inoculation with PP produced importantly beneficial effects on sensory quality improvement of dry fermented sausage.

  • The Purpose of this study was to propose the most effective packaging method and storage conditions to apply to home-delivered meals for the elderly Changes in the physical and sensory qualities of pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok, in wrap packaging, top sealing and vacuum packaging were evaluated during storage at 25, 4 and -18$^{\circ}C$, for 5 days. The speed of falling-off in the foods qualities, under chilled and frozen storage conditions did not differ much as the 5 day storage period was too short for a proper assessment. The sensory characteristics of taste and texture were better evaluated in the chilled than in the frozen storage. The most effective packaging method at all the storage temperatures was the vacuum packaging, which assured the safety of the foods by the removal of oxygen. The lightness, springiness and hardness were significantly influenced by the storage temperature, period and packaging method, while the sensory characters were affected by storage temperature and the period. In conclusion, the quality of the vacuum packed pan fried oak mushroom and meat and soy sauce glazed hair tail, in frozen storage, were still fresh after the five days of the experiment. The shelf-life of those foods with wrap packaging, in chilled storage, were suggested to be three days. The quality of the roasted dodok, with vacuum packaging in chilled storage, was preserved for five days.

  • The characteristics of rice-breads with wet-milling and dry-milling rice-flours were investigated. Rice-breads by wet-milling had a good fermentation than the breads by dry-milling. Also, the fermentation of mugwort rice-breads was lower than those. Rice-breads by dry-milling indicated the higher value in hardness and the lower value in springiness, cohesiveness and chewiness than rice-breads by wet-milling. Also, mugwort rice-breads was the higher value in hardness, springiness, chewiness and the lower value in cohesiveness than rice breads. The test of the sensory characteristics for rice-breads showed that moistness, springiness, chewiness was higher for rice-breads by wet-milling. The sensory characteristics of mugwort rice-breads were lower than those, of rice-breads except the chewiness. Overall quality of rice-breads by wet-milling was higher than that of rice-breads by dry-milling. The overall quality of mugwort rice breads was higher than that of rice-breads by wet-milling, but lower than that of rice-breads by dry-milling.

  • This study was conducted to evaluate the quality characteristics and antioxidant activities of rice flour sponge cakes containing 0, 20, 30, 40, and 50% Helianthus tuberosus powder (HTP). As HTP content of sponge cake increased, the pH of sponge cake batter significantly decreased, whereas specific gravity significantly increased (p<0.05). Meanwhile, volume and symmetry indices of sponge cake were inversely proportional to HTP amount. Further, with higher HTP content in sponge cake, L and b values of crumbs significantly decreased (p<0.05), whereas a value significantly increased (p<0.05). L, a, and b values of crust significantly increased with higher HTP content. For texture characteristics, hardness, cohesiveness, gumminess, and chewiness of sponge cake significantly increased (p<0.05),whereas cohesiveness did not significantly change. In the sensory evaluation test, rice sponge cake prepared with 10% HTP showed the highest sensory scores in terms of color, flavor, taste, softness properties, and overall preference. The levels of total polyphenol compounds and DPPH radical scavenging activities of rice sponge cakes significantly increased with higher HTP contents (p<0.05). The results of this study suggest that rice sponge cake containing 10% HTP is the most appropriate for quality characteristics and sensory evaluation. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to satisfy consumer tastes.

  • Tenderization of beef by the addition of barks(Morus alba Linne) and its sensory properties were observed by shearing test, cooking loss, pH, protein content and sensory evaluation. Shear force was decreased as the addition level of barks (Morus alba Linne) increased. Tenderization effect of beef was increased 8,8% at the addition level of 2.5%, 25% at 5.0%, 4.7% at 7.5%, 58% at 10% barks(Morus alba Linne). Cooking loss was observed 44.50% at the no addition, 45.3% at 2.5%, 45.8% at 5.0%, 47.5% at 7.5%, 50.0% at 10% addition level of barks (Morus alba Linne). As the addition level of barks(Morus alba Linne) increased pH of cooked beef decreased to the range of 5.6 to 5.46. As the addition level of barks (Morus alba Linne) increaed protein content of beef decreased whereas protein content of cooled liquor increased. The addition of barks(Morus alba Linne) improved the sensory quality of cooked beef. Especially, tenderness scored the highest value in 10% added beef and other quality factors color, flavor, juiciness and overall quality were evaluated significantly high in 5% added beef. Therefore 5% addition level of barks(Morus alba Linne) for cooking beef was suggested as the desirable level of addition.

  • The purposes of this study were to provide the basic information on the cookies made with barley and oatmeal powder and to establish an optimum formula for the development of cookies with high content of fiber. Cookie samples were prepared with barley and oatmeal at various mixing ratios (2:0, 1:1, 2:1, 0:2), and the chemical properties, textural characteristics, and sensory properties of them were evaluated. The contents of carbohydrate and moisture of barley cookies were higher than oatmeal cookies, but the contents of crude protein, crude fat, crude ash and total fiber of oatmeal were higher than those of barley. The moisture content was the highest in the cookies of oatmeal and the lowest in barley-used ones. The cookie volume was increased by the addition of barley and oatmeal. The results of sensory evaluation showed that the cookies containing barley and oatmeal (2:1) was significantly more preferable in overall acceptability than the others. Hunter color test showed that the lightness was the highest in control, but the redness and yellowness were increased in the cookies with barley and oatmeal compared with the control.

  • The purpose of this study was to evaluate the effects of bundle type (BT) and substitution with spent laying hen (SH) surimi on quality characteristics of imitation crabsticks made from Alaska Pollack (AP) during 6 wk of cold storage. Diagonally bundled samples had poorer gel characteristics and more lipid oxidation when compared with straight bundled ones (p<0.05). The color of diagonally bundled imitation crabsticks deteriorated with storage time (p<0.01). However, BT did not affect sensory characteristics (p>0.05). SH substitution had an effect on most quality characteristics of imitation crabsticks; darker and poorer gel characteristics were observed and its effect on sensory evaluation was seen at the initial storage. Thus, BT and SH substitution can be considered to have a slight effect on eating quality of imitation crabsticks, despite their negative effects on color, gel characteristics, and lipid oxidation.

  • We prepared Tofu-sulgi by adding tofu and then analyzed the final product in terms of its nutritional quality, rheological characteristics and sensory tests. While the calorie quantity of Sulgi with Tofu was relatively low compared to that of Baeksulgi, it contained the dietary fiber, calcium and iron that were not present in Baeksulgi. Since Baeksulgi holds a large amount of carbohydrates, it shows a higher weight due to its dense fiber. On the other hand, Sulgi with Tofu showed a relatively low level of tofu protein despite the increased amount of tofu protein. This demonstrated the soft characteristics of Sulgi with Tofu. Also, the results of the sensory test showed that Sulgi with Tofu exhibited a higher preference than Baeksulgi in terms of its taste, flavor and fiber content. The preparation method of Sulgi with Tofu in this study used the natural grinding of tofu without removing the moisture. Also the use of both non-glutinous and glutinous rice flour that can be obtained easily in the public market, are convenient due to their characteristics of easy storage and no property change. Therefore, the preparation method of Sulgi with Tofu is quite convenient as compared to that of traditional Dduk (Korean rice cake) including Baeksulgi. From the perspectives of nutritional content, rheological characteristics and taste preference, Sulgi with Tofu fared better than Baeksulgi. Considering the overall quality characteristics of Sulgi with Tofu, we believe that the addition of tofu could contribute positively toward the quality characteristics of Sulgi.
