The texture and descriptive sensory characteristics of a Korean rice cake(Karedduk) with added emulsifier were investigated after 2 and 24 hrs of storage at $5^{\circ}C$. The emulsifier, SP, was added at 0, 0.1, 0.5 and 1% levels to the dry rice flour. In the amylogram, the peak viscosity(P), hot paste viscosity(H) and cold paste viscosity(C) of the rice flour with added emulsifier were higher than those of the control. The texture property analysis by a Texture Analyzer revealed that the springiness, cohesiveness and adhesiveness of the Korean rice cake(Karedduk) with added emulsifier were similar to those of the control, while chewiness, gumminess and hardness were lower compared to the control. Also, the hardness by sensory characteristics was significantly different as compared to the control. Lastly, adding emulsifier to the Korean rice cake(Karedduk) was effective at retarding retrogradation.

Purpose: This study was conducted to understand the factors that affect the acceptance of gluten-free rice pasta samples prepared with added buckwheat, mungbean, and acorn starches, and to compare sensory characteristics of samples with those of 100% semolina pasta. Methods: Descriptive analysis of pasta was conducted by 12 trained panels. Acceptance test was carried out by 40 consumers using 7-point hedonic scale. Collected data was statistically analyzed by principal component analysis, and partial least squares regression analysis. Results: Quantitative descriptive analysis showed that increasing amount of buckwheat, mungbean, and acorn starches resulted in significant improvement in gluten-free rice pasta properties, especially texture, hardness, chewiness, roughness, and al dente with increasing amount of sample starches, and decreased adhesiveness. In acceptance test, appearance and texture of gluten-free rice pasta with mungbean starch were preferred than pasta made with 100% rice. Flavor and taste was preferred in pasta with buckwheat starch than other pasta samples. Rice pasta with 30% buckwheat starch showed the highest score in overall acceptance among rice samples. Conclusion: This study suggested that adding mungbean starch could improve texture of gluten-free pasta, and adding buckwheat starch would improve taste and flavor of gluten-free rice pasta.

The objectives of this study were to evaluate the sensory properties of various natural flavor enhancers (NFEs) and to understand the effects of NaCl and temperature on the sensory characteristics of these NFEs. Descriptive analysis was conducted to evaluate six types of NFEs: yeast extract-based NFE, three; fish sauce-based NFE, one; soy sauce-based NFE, one; and hydrolyzed peptide NFE-based, one. The effects of NaCl (no addition vs. addition) and temperature ($20^{\circ}C$ vs. $55^{\circ}C$) were also evaluated. The results showed that the overall flavor intensity and sensory properties of the NFEs differed greatly depending on the NFE source. Two of the yeast extract-based NFEs elicited higher umami intensity than the other NFEs. Addition of NaCl increased some of the savory-related flavors and the perceived viscosity of the sample. Aroma intensities, in general, were enhanced at the higher temperature, whereas flavor, aftertaste, and mouthfeel attributes were perceived to be stronger at the lower temperature.

This descriptive analysis study investigated the sensory characteristics and the drivers of liking for seven types of makgeolli differing in grain composition and pasteurization conditions. Six trained panelists participated in the descriptive analysis. In the consumer acceptance test involving 23 males and 34 females, two of the seven varieties were excluded due to their similar sensory characteristics. Analysis of variance, principal component analysis, and partial least square regression analysis were conducted. Sensory characteristics of makgeolli varied markedly depending on the ingredients and processing methods. Makgeolli samples with relatively high content of millet flour were characterized as being smooth and strong, with a roasted carbohydrate flavor, whereas samples with enriched rice content were rated high in attributes such as bitterness, carbonation, and residual flavor. Sourness decreased in pasteurized samples. Participant's age rather than gender influence the liking for makgeolli. Older consumers tend to prefer samples with stronger flavor than did younger consumers. Clustering consumer groups based on the preference for makgeolli samples provided profound insight concerning the beverage aspects that were appealing, which should be useful in consumer targeting of particular varieties of makgeolli.

This study was conducted to understand sensory characteristics of commercial functional beverages, to analyze and the drivers of liking and disliking of it by Korean consumers. Descriptive analysis and consumer taste testing were conducted with ten commercial products of functional beverages. Samples were consisted of good for beauty, relieving hangovers, and health tonics. For the descriptive analysis, 45 attributes were developed by ten panelists and it shows differences among the all samples. For the consumer testing, 81 panels evaluated the overall liking, acceptance of appearance, odor, flavor, and texture of 10 samples. As a result, attributes of brightness, yellow color, Nurungji flavor, roasted bean power flavor, and milky texture of functional beverages were positive drivers of liking, but attributes of astringent texture, bitter taste, and viscosity were negative drivers of liking on the commercial functional beverages.

This study was carried out to develop character notes and to define the terminology for the evaluation of soybean curd using quantitative descriptive analysis. Panelists were selected according to their performance with ranking on basic tastes, flavor and texture properties related to soybean curd. After being trained, they identified the following attributes and defined the terminology: appearance(smoothness of the surface, amount of cracks, yellowness, grayness), flavor(sweet, salt and bitter tastes, cooked bean, raw bean, wet wheat flour, roasted bean, astringency), and textural properties(hardness, elasticity, inner moistness, coarseness, adhesiveness, and residuals). Reference samples for flavor attributes were also determined. Four types of commercial soybean curd were evaluated with the technique developed. Among soybean curd samples, there were significant differences in the intensity of all sensory attributes, confirming appropriateness of the evaluation methodology.

Various sensory technologies have been used at different stages of product development. In this paper, the examples of sensory studies in teas and cosmetics were shown, and these could help to increase the contribution of sensory sciences to the development of products in the industry. In classical approach, descriptive analysis with trained panel and consumer acceptability test are very important to identify the sensorycharacteristicsthatdriveconsumeracceptability of products. Recently, some quick and easy sensory evaluation methods were introduced such as CATA (check-all-that-apply), sorting, and $Napping^{(R)}$, etc. to gather information about consumers' perception of the sensory characteristics of products. Although there are many sensory methodologies available in the product development phase, the most important thing is that these have to be correctly selected and designed for target consumers, products, and research purposes in order to develop a successful product.
