  • To investigate the optimum ratio of sucrose replacement with high intensity sweeteners, the sensory characteristics and consumer acceptability of coffee drinks containing sucralose and acesulfame-K were studied using descriptive analysis and consumer testing. The relative sweetness of the sucralose and acesulfame-K to sucrose were 600-700 and 200-400 times greater, respectively, within the coffee drink system. The sucrose-replaced coffee drinks containing 100% sucralose, as well as mixtures of sucralose/acesulfame-K in ratios of 75/25 and 50/50, showed sensory profiles that were more similar to those of the original 100% sucrose coffee drink, which had a greater sweet taste, vegetable cream, caramel flavor, viscosity, and mouthcoating. These samples were not different from the 100% sucrose sample in terms of overall consumer acceptability.

  • This study was conducted to analyze sensory characteristics and consumer acceptance with cookies made using various levels(0, 2, 4, 6 and 8% w/w) of Chrysanthemum indicum L. powder. Ten panels assessed sensory characteristics using a 15-point hedonic scale and forty-five consumers evaluated their acceptance based on a 7-point hedonic scale and best-worst scaling. The descriptive analyses reveled that cookie flavor did not differ significantly between the 2% added sample and the control. Cookie color and after taste increased significantly, while hardness, roasted taste, and sweetness taste decreased significantly according to increasing Chrysanthemum indicum L. powder concentration. In addition, the results of consumer acceptance showed that the overall acceptability, appearance, color, flavor, and taste decreased significantly in response to increasing Chrysanthemum indicum L. powder concentration. However, color, flavor, taste and overall acceptance with cookies did not differ significantly differ between the 2% and 4% sample. Additionally, among the cookies made with Chrysanthemum indicum L. powder, the 2% sample received the highest scores. In conclusion, the sensory optimal ratio of Chrysanthemum indicum L. powder was 2% based on the descriptive analysis of sensory characteristics and the consumer-acceptance testing.

  • This study was conducted to understand the sensory characteristics and consumer acceptance for the commercially available clear broth for noodles. Totally, eight different clear broth samples were evaluated in this study. Seven trained panelists developed and evaluated sensory characteristics in the descriptive analysis. Significant differences (p<0.05) were obtained for all 28 attributes evaluated. Descriptive data was obtained by performing multivariate analysis of variance to identify differences between samples. Principal component analysis (PCA) was performed on the mean values of descriptive attributes obtained in the descriptive analysis, and summarizes the sensory characteristics of clear broth for noodles. PCA of the clear broths revealed that the first two principal components are responsible for 80.66% variations. For sensory testing, 160 consumers were recruited, and their acceptance for each sample was assessed. Consumer data was obtained by applying partial least square-regression (PLSR) to establish the relationship between the descriptive data and the consumer acceptance data.

  • This research aims to study the effect of consumer ethnocentrism and animosity towards the purchase of Korean visual arts products by Chinese consumers. Total of 302 questionnaires were distributed for measuring the constructs using the online survey website (www.sojump.com). All the questionnaires were validated and tested for further statistical analysis through exploratory factor analysis (EFA) and later a confirmatory factor analysis (CFA) using SPSS 22.0 and AMOS 22.0 statistical systems. In addition, structural equation modeling technique (SEM) was applied for testing the hypotheses. Among all variables, consumer ethnocentrism plays the most negatively significant role, followed by animosity toward buying Korean products. Fortunately, there is a positive variable, cosmopolitanism, that can help mitigate the impact of this hostility, and more interesting results are described in detail in the current paper. This study has been added value between theory and practice exploring ethnocentrism and animosity effects, and more theoretical and managerial implications are discussed.

  • Purpose: This research aims to test the measurement invariance of the consumer-based brand equity scale on Turkish and Syrian university students who live together but are from different cultural groups. Research design, data, and methodology: The consumer-based brand equity scale developed by Buil et al. (2008) is applied to the participants. In testing the consumer-based brand equity scale, the Netflix brand, which is considered well-known by both cultural groups, is preferred. It is thought that choosing an internationally recognized brand would facilitate the conduct of this research. Structural invariance and measurement invariance are tested using structural equation modeling. Results: The consumer-based brand equity scale has measurement invariance on Turkish and Syrian university students. Therefore, it has been revealed that the responses of participants from both cultures regarding the Netflix brand are comparable. Conclusion: The findings of the study provide clues for practitioners to review their distribution strategies. As a matter of fact, cultural studies conducted in different countries are common. Still, the originality of this study is ensured by the profile of participants who live in the same country but come from different countries.

  • This study examines the effect of cosmetic certification marks on consumer behavior. The underlying objectives of this study are threefold. First, it explores whether the certification mark inserted into the cosmetic package-such as marks denoting quality assurances, ethical practices (specifically, pertaining to animal testing), and recycling packaging-affects consumer responses. Second, it investigates whether a higher number of certification marks leads to heightened positive consumer responses. Third, it analyzes the potential moderating effect of consumers' certification mark knowledge on the relationship between certification marks and consumer responses. In the pretest, certification marks with higher recognition were selected as stimuli, and a survey involving a total of 550 male and female consumers was conducted. The collected data were analyzed through ANOVA and post-hoc tests. The findings of this study confirm a significant difference in consumer responses to products based on the certification marks inserted in the cosmetic packaging. Compared to clusters without a certification mark, groups with two or more certifications (recycling certification + ethics certification, recycling certification + quality certification, recycling certification + ethics certification + quality certification) exhibit significant consumer responses. Second, more certification marks did not result in an increase in positive consumer responses. Third, a moderating effect of consumers' cosmetic certification knowledge on the certification mark-consumer response relationship was not found. The findings of this study have implications for developing product promotion strategies that leverage cosmetic certification marks as a marketing tool.

  • According to an increase in demand for polyurethane soft foam for thermally insulated containers, the purpose of this study is based on redefining existing rigid polyurethane foam insulation KS standard which has been limited to building material-based authentication techniques. Since there are arising concerns of consumer rights and safety due to humidifier fungicides and urethane track incidents, there are elements to be further researched on rigid polyurethane foam insulation for refregerated containers. Thus, we reviewed the prior standards for rigid polyurethane foam insulation and verified the validity of certification testing method for the new standard with self-foamed polyurethane.

  • The Personal sense of uniqueness (PSU) is positively associated with subjective well-being and has been recently shown its correlation with happiness, influencing consumer's experience behavior. However, the effects of hedonic and eudaimonic experience on conspicuous and inconspicuous (consumer's need for status and inner fulfillment) are unknown. The purpose of this research is to address a gap existing in the literature by testing the effects of PSU on hedonic and eudaimonic leisure experiences and how happiness leisure experiences effects conspicuous and inconspicuous consumption. The relationships hypothesized in the model are tested using partial least squares structural equation modeling (PLS-SEM) and bootstrapping procedure. Data was gathered using a self-administrated survey, answered by 200 consumers based on consumers' leisure experiences. The findings of this study suggest that (i) PSU positively and significantly influence hedonic and eudaimonic happiness; (ii) the effect of PSU on eudaimonic happiness is higher than in hedonic happiness; (iii) eudaimonic happiness positively and significantly influence conspicuous and inconspicuous consumption; and (iv) hedonic happiness negatively and significantly influence conspicuous and inconspicuous consumption. This study helps fill a gap in the literature by introducing and testing the effect of hedonic and eudaimonic leisure experiences and the relationship between these constructs and PSU and (in) conspicuous consumption.
