  • This study was carried out to make the new products of color moot as a functional food by variation of the color and flavor through addition of gamgyul, Daccus Carota Var. Sativa, Vitis vinifera, soy sauce, and Pimpinella brachycarpa N., respectively. For all the products, the color was observed by Colorimeter and the sensory evaluation was performed to evaluate their effectiveness and usefulness. The A$_w$ (water activity) test of color mooks has performed to examine their water activity individually. The A$_w$ of color moot was higher than that of the white one. The characters of texture of color mook as a function of the amount of the color and the flavor added were measured by a texture analyzer (XT-RA, Texturometer). By the TPA test, the rainbow and orange color mook examined were high in the springiness.

  • In order to improve the physical properties of food such as texture and food self-life. Transglutaminase(mTG) from Streptoverticillum morbarense was prepared. In the preliminary experiments, presence of proteases in the crude enzyme did not improve the texture of dough, which mean the inteference of mTG reaction by the proteases. Among the cation exchange resins tested for the removal of proteases, Monoplus S 100(Bayer, Germany) was the most efficient resin with 20 fold increase in the mTG/protease activity ratio. By further purification steps with a quaternary ammonia salt resin and a gel permeation chromatography, proteases were effectively removed from the preparation. Therefore, the improvement of flour texture was shown by adding the protease-free mTG.

  • To study the effects of soil moisture and texture on characteristics of growth, content of saikosaponins and activity of antioxidative enzymes in Bupleurum falcatum L., content of saikosaponins(a, c and d) and activities of superoxide dismutase(SOD) and peroxidase(POD) were investigated with two Bupleurum genotypes(Jangsoo and Samdo). Two Bupleurum genotypes were grown under different soil moisture(deficit, normal, surplus) and soil texture(sandy, sandy loam, loam) conditions. Among the tested soil conditions, dry weight accumulation rate of both cultivars could be ranked in the order surplus > normal > deficit soil for soil moisture and sandy > sandy loam > loam for soil texture. Under the surplus soil condition, growth retardation of Samdo cultivar was more severer than that of Jangsoo. Furthermore, content of saikosaponin a, d, and c also could be ranked in the order deficit > normal > surplus and sandy > sandy loam > loam for soil moisture and texture, respectively. Although both Jangsoo and Samdo cultivars grown under water deficit condition showed the highest POD and SOD activity, in general POD and SOD activity in both shoot and root was remarkably high in Jangsoo cultivar compared with Samdo. Saikosaponin content of root was positively correlated with POD and SOD. However, shoot and root length were negatively correlated with POD.

  • Purpose: The aim of this study was to evaluate the quality characteristics of rice nutritional bars prepared by adding Chinese artichoke (CA) powder to the rice powder. Methods: CA rice nutritional bars were prepared with various levels of CA powder (0%, 5%, 10%, 15%, and 20%) and designated as CA0 (without CA powder), CA5, CA10, CA15, and CA20, respectively. The total phenolic content, DPPH free radical scavenging activity, moisture content, pH, baking loss rate, leavening rate, volume, color, texture analysis, and sensory evaluations of rice nutritional bars were performed. Results: The total phenolic content and DPPH free radical scavenging activity exhibited an increase with increase in the substitute amount of CA powder. The results showed that the pH of rice nutritional bars decreased in all sample groups as the content of CA powder increased. The volume of the sample group with CA powder was higher than that of CA0. As the content of CA powder increased, lightness of the rice nutritional bars crumbs decreased while redness and yellowness increased. The texture analysis of rice nutritional bars showed that hardness, gumminess, and chewiness were the highest in CA0 while springiness and cohesiveness were the lowest in CA0. With respect to characteristic intensity rating, the taste, flavor, and softness of rice nutritional bars increased with increasing amounts of CA powder. In terms of consumer acceptability, CA15 and CA20 received the highest scores with respect to texture. Conclusion: Therefore, the results of this study indicate that replacing 15% of the rice powder with CA led to an efficient enhancement in the antioxidant and nutritional values of rice nutritional bars as well as the sensory quality.

  • Objective: This study was aimed to investigate the effect of fresh and dried hydrolyzed Cordyceps militaris (CM) mushroom with proteolytic enzymes; bromelain (CMB), flavorzyme (CMF), and mixture of bromelain: flavorzyme (CMBF) on quality properties of spent hen chicken. Methods: Mushroom extract (CME) were combined with three proteolytic enzyme mixtures that had different peptidase activities; stem bromelain (CMB), flavorzyme (CMF), and mixture of stem bromelain:flavorzyme (CMBF) at (1:1). The effect of these hydrolysates was investigated on spent hen breast meat via dipping marination. Results: Hydrolyzation positively alters functional properties of CM protease. in which bromelain hydrolyzed group (CMB) displayed the highest proteolytic activity at 4.57 unit/mL. The antioxidant activity had a significant increment from 5.32% in CME to 61.79% in CMB. A significantly higher emulsion stability index and emulsification activity index compared to CME were another result from hydrolyzation (p<0.05). Texture properties along with the shear force value and myofibrillar fragmentation index were notably improved under CMB and CMBF in fresh condition. Marination with CM mushroom protease that was previously hydrolyzed with enzymes was proven to also increase the nucleotide compounds, indicated by higher adenosine 5'-monophosphate (AMP) and inosine 5'-monophosphate (IMP) in hydrolysate groups (p<0.05). The concentration of both total and insoluble collagen remained unchanged, meaning less effect from CM protease. Conclusion: This study suggested the hydrolyzation of CM protease with bromelain or a mixture of bromelain:flavourzyme to significantly improve functional properties of protease and escalate the taste-related nucleotide compounds and texture profiles from spent hen breast meat.

  • The objective of this study was to assess the quality characteristics of Sulggitteok prepared with different ratios of chestnut powder: 0%, 5%, 10%, 15%, and 20%. The moisture content of the chestnut Sulggi without added chestnut powder was 38.24% than that of any other chestnut powder added groups and gradually decreased from 33.34~26.27% based on the addition of chestnut powder. In terms of color, the lightness (L) decreased significantly but redness (a) and yellowness (b) significantly (p<0.001) increased with increasing contents of chestnut powder. The total polyphenol content and DPPH free radical scavenging activity increased as the amount of chestnut powder increased and decreased. Total phenol contents of phenol contents was higher in the 10% added group (347.50 mg GAE/100 g) and DPPH radical scavenging activity was significantly higher in the 5% added group ($69.35{\pm}2.02%$) and 10% added group ($74.33{\pm}2.29%$). Texture profile analysis showed that the hardness, adhesiveness, chewiness were higher than that of the control. The result of sensory evaluation test and the overall acceptability showed that the taste, color, flavor, chewiness, softness and overall acceptability were the highest in the 10% added group while the color and flavor showed no significant different group. Based on these results, it is suggested that chestnut Sulggi with up 10% added chestnut powder can be developed as products.
