  • The objective of this study was to develop functional rice coated with yacon roots extracts and to evaluate the antioxidant properties and physiological activity of rice coated with yacon extract. The washed rice was coated by spraying yacon extract at 10, 20, 30, and $40^{\circ}Brix$ and dried at room temperature. The moisture contents, color changes, antioxidant properties as total polyphenolics and DPPH radical scavenging activity and instrumental texture property and sensory evaluation change in the yacon root extracts coated rice and uncoated cooked rice were observed during 3 days of storage. Increasing the coating concentration was associated with lower color values(L value) and moisture contents. Total phenolics and DPPH radical scavenging properties generally increased in the cooked rice coated with yacon root extract more than the control (non-coated rice). However, D-20($20^{\circ}Brix$ of the yacon root concentration) resulted in better textural properties and sensory overall acceptability in cooked rice on 0 and 3 storage days. It was concluded that the optimum coating ration of rice and added functional yacon rice were $20^{\circ}Brix$ and 7% respectively, in proportion to the total weight of raw rice.

  • The principal objectives of this study were to analyze the physiochemical properties of four mulberry fruit beverages (MFBs) and develop descriptive analysis procedures for evaluation of their sensory characteristics. Soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of MFBs were determined. All MFB samples showed significantly different physicochemical properties ($p$<0.01). Ten highly trained panelists identified the following 11 sensory attributes in the MFBs and defined the terminology for each attribute : turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, and throat hit, refreshing, and astringent for textural characteristics. There were significant differences in the 10 sensory attributes among the MFB samples ($p$<0.001). In color, the value of MFB3 was significantly higher than those of others ($p$<0.05). In taste and overall acceptance, the values of MFB2 were significantly higher than those of others ($p$<0.01, $p$<0.001). Descriptive terminology of the developed MFBs could explain the sensory attributes of the samples according to this result. Based on this, proper analysis and sensory evaluation techniques could be applied to other fruit beverages to establish their physiochemical characteristic and descriptive sensory attributes.

  • The purpose of this study was to analyze the physiochemical properties of blackberry fruit beverage(BFB) and to develop a descriptive analysis procedure for evaluating the sensory characteristics of BFB. The amount of soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of BFB were determined. All BFB samples demonstrated significantly different physicochemical properties(p<.01). Ten highly trained panelists identified the following eleven sensory attributes in the BFB and defined by standardized terminology for each attribute; turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, throat hit, refreshing, as well as astringent grade for textural characteristics. There were significant differences in all the eleven sensory attributes of the BFB samples(p<.001). Descriptive terminology used in the BFB analysis was capable of classifying the sensory attributes of the BFB. Based on these results, the analysis method and sensory evaluation techniques used in this study could be reasonably applied to other fruit beverages for establishing similar physiochemical characteristic and descriptive sensory attributes.

  • Dasik is a kind of traditional Korean dessert, which has polysaccharides as the major base. Dasik was prepared using rice and various ingredients and its antioxidant properties were determined. In addition, textural changes and sensory evaluation were conducted on Dasik during 7-day storage at $4^{\circ}C$. Dasik containing brown rice, red ginseng, and rice bran oil showed higher radical scavenging ability, reducing power, total flavonoid, and total phenolic contents among tested rice-based samples. Dasik prepared using black sesame seeds showed the highest radical scavenging ability and reducing power compared to rice-based Dasik. In sensory evaluation, 10 trained panelists found that hardness of the rice-based Omija Dasik sample increased significantly (P<0.05) while moistness and softness attributes decreased as the storage period of Dasik increased. The roasted bean Dasik and black sesame Dasik samples were evaluated similarly and their moistness decreased significantly (P<0.05) with longer storage period. The overall and texture acceptability of the rice-based Omija Dasik and the roasted bean Dasik samples decreased significantly (P<0.05), and scores of willingness to try again of the rice-based Omija Dasik decreased as the storage period of Dasik increased. Positive or negative correlations among the results from sensory evaluation and textural analysis were observed in Dasik.

  • To establish the optimum formular for processing bread with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5 and 7% based on a flour weight. Evaluation was performed on the rheological and sensory profile of bread, such as specific loaf volume, water holding capacity(WHC) and height, appearance and Hunter's color value, mechanical texture properties, and sensory value. Increase in the addition of SHF led to the tendency that the expansive force of dough fermentation reduced, and an increase in the textural properties of bread. And cohesiveness, gumminess, and chewiness indicated the tendency of a little reduction as influenced by adding more dried Hizikia fusiformis powder. As for sensory properties and flavor components of the white bread, in case of color and flavor, more than 3% of increase in the addition of the dried Hizikia fusiformis powder led to a drop in preference, and more addition led to a fall in taste and softness. Overall, it was found that adding less than 3% of dried Hizikia fusiformis powder is proper for dough in breadmaking.

  • The physiological and sensory properties of breads made from waxy black rice flour (WBRF) and wheat flour were investigated. The waxy black rice bread was manufactured with 10, 20, 30, or 40% waxy black rice flour(w/w). The bread volume decreased from 2,096.7 mL to 1,703.4 mL as the WBRF content increased from 0% to 40%. The lightness(L-values) decreased with increasing WBRF concentrations, and the redness value(a-values) increased. The yellowness(b-values) slightly decreased with increasing WBRF content. The textural characteristics of the bread c겨mb were influenced by additions of WBRF. The breads containing WBRF had decreases in hardness for the 10% and 20% WBRF groups, whereas increases in hardness were shown with the 40% addition of WBRF. The springiness decreased with increasing WBRF content. The gumminess and chewiness of the waxy black rice bread decreased at the 10% and 20% additions. In the sensory evaluation, sensory scores decreased with increasing WBRF content for the appearance, external color, crumb color and grain of the waxy black rice bread. Overall acceptability for the 10% and 20% WBRF additions did not differ significantly from the score of the control group.

  • Textural properties of tofu manufactured with micronized full-fat soyflour (MFS) were enhanced by the addition of soy protein isolate, whey protein concentrate, chitosan oligosaccharide and mushroom powder. The MFS solution (14.2% solid content) was converted to semi-solid tofu by a two-stage heat treatment with the addition of 4% coagulant mix. The MFS tofu was evaluated by a compression test as well as sensory evaluation. To produce the semi-solid gel (MFS tofu) with reasonably high strength and toughness, the MFS solution with 14.2% solid content and 7.0% protein had to be heat treated at 121$^{\circ}C$ for 3min. The relative toughness of MFS tofu was increased by the addition of SPI, showing a 144% increase. The toughness of MFS tofu prepared with the MFS/SPI mixture was greatly increased by the addition of WPC at the level of 0.7% and the water separation from MFS tofu was greatly reduced. Furthermore, the toughness and strength of MFS/SPI tofu was enhanced by the addition of 0.1% chitosan oligosaccharide and 0.2% mushroom powder. The sensory evaluation of the tofu fortified with SPI, chitosan oligosaccharide and mushroom powder was superior to that of MFS tofu, with a higher score for overall preference.

  • This study was conducted to evaluate the quality characteristics (proximate composition, fatty acids, amino acids, sensory and textural properties) of whole body and dorsal muscle of olive flounders fed extruded pellets (EP) compared to raw fish-based moist pellets (MP). The olive flounders in this study were reared from 300 g to 1000 g for 7 months by feeding either EP or MP. The fatty acids and total amino acids of the whole body and dorsal muscle of the fish were similar among both groups. The major fatty acids in whole body and dorsal muscle werepalmitic acid and oleic acid. Finally, no significant differences were observed between groups for sensory and textural properties of the muscle. These results suggest that EP could be developed to replace MP without adverse effects on olive flounder quality.

  • This study explored the physicochemical, textural, and sensorial properties of a meat analog (MA) as compared to beef and pork meats. Results illustrate that MA patties had lower moisture, fat, and protein content, as well as higher ash and crude fiber than beef and pork. Likewise, MA patties had a higher pH, lightness (L*), and redness (a*) than either beef or pork. Pork meat exhibited the highest released water (RW) and cooking loss (CL) values, followed closely by MA with beef displaying the lowest values. Regardless of patty type, the post-cooking diameter patties were reduced significantly (p<0.05). However, the Warner-Bratzler shear force (WBSF), hardness, chewiness, and gumminess of beef were significantly higher than that of either pork or MA. The visible appearance of MA patties had more porous and loose structures before and after cooking. Consequently, based on sensory parameters, MA patties demonstrated the higher values for appearance and firmness, followed by beef and pork respectively, although the difference was not statistically significant. Therefore, the current study demonstrated that some physicochemical, textural, and sensory characteristics of beef and pork exhibited the most similarity to MA.

  • This study investigated the effects of the number of washes and alkaline treatments ($NaHCO_3$ concentrations) and the concentration of potato starch on the quality of fish meat paste products prepared from sand lance Ammodytes personatus Girard. We found significantly (P<0.05) higher ratings for the all textural parameters (hardness, brittleness, elasticity, and cohesiveness) of the sand-lance meat paste products (SLMPPs) that were washed three times with a 0.5% $NaHCO_3$ concentration. We determined that an 8% concentration of potato starch leads to the best textural properties in SLMPPs. As the amount of potato starch was increased, the redness values of SLMPPs decreased significantly (P<0.05), but the differences in the sensory evaluation parameters (texture, flavor, taste, and overall acceptability) between the SLMPPs were not significant.
