Variations in U.S. Consumers' Acceptability of Korean Rice Cake, Seolgitteok, with respect to Sensory Attributes and Nonsensory Factors.

Because the Korean rice cake, Seolgitteok, is mainly prepared with rice flour containing no gluten-protein associated with celiac disease, it can be considered for inclusion in a gluten-free diet. However, Western consumers may be unlikely to enjoy the plain flavor and chewy texture of Seolgitteok. This study aimed to determine both sensory and nonsensory factors that might affect U.S. consumers' acceptability of Seolgitteok. A total of 119 U.S. consumers rated 5 Seolgitteok samples, differentiated by descriptive sensory analysis, with respect to hedonic impression and just-about-right aspects of sensory attributes. Nonsensory factors such as demographic profile, innovativeness, social representation, sensation-seeking, and personality traits were also assessed. Addition levels of brown rice flour (0% to 100%) and sugar (5% to 20%) not only enriched flavor, but also lessened chewiness of Seolgitteok, thereby increasing an overall hedonic impression. Moreover, consumer acceptability of Seolgitteok varied with respect to nonsensory factors. Seolgitteok was more appreciated by males, sensation seekers, and individuals constrained by social desirability than by other groups. In conclusion, these findings demonstrate that U.S. consumers' acceptability of Seolgitteok varies not only by sensory attributes such as rice flavor, sweetness, and chewiness, but also by nonsensory factors such as gender, sensation-seeking characteristics, and personality traits.

Effects of smoking and marination on the sensory characteristics of cold-cut chicken breast filets: A pilot study.

This study aimed to determine individual and combined effects of smoking and marination on the sensory characteristics of boneless, skinless chicken breast meat. Four types of cooked, cold-cut chicken breast meat, i.e., marinated cooked, marinated smoked, and controls of non-marinated cooked and non-marinated smoked chicken, were evaluated for 28 sensory characteristics. Marination significantly increased saltiness, sweetness, roasted flavor, smoked flavor, and moistness of the cold-cut chicken breast meat. In addition, smoking significantly enhanced the saltiness, bitterness, roasted flavor, smoked flavor, and moistness of mass. Interestingly, a combination of smoking and marination processes resulted in a synergistic increase in the perceived moistness of mass compared to their individual treatments. In conclusion, this study demonstrates individual and combined influences of smoking and marination on the sensory characteristics of cold-cut chicken breast meat.

Color and illuminance level of lighting can modulate willingness to eat bell peppers.

BACKGROUND: Food products are often encountered under colored lighting, particularly in restaurants and retail stores. However, relatively little attention has been paid to whether the color of ambient lighting can affect consumers' motivation for consumption. This study aimed to determine whether color (Experiment 1) and illuminance level (Experiment 2) of lighting can influence consumers' liking of appearance and their willingness to eat bell peppers. RESULTS: For red, green, and yellow bell peppers, yellow and blue lighting conditions consistently increased participants' liking of appearance the most and the least, respectively. Participants' willingness to consume bell peppers increased the most under yellow lighting and the least under blue lighting. In addition, a dark condition (i.e. low level of lighting illuminance) decreased liking of appearance and willingness to eat the bell peppers compared to a bright condition (i.e. high level of lighting illuminance). CONCLUSION: Our findings demonstrate that lighting color and illuminance level can influence consumers' hedonic impression and likelihood to consume bell peppers. Furthermore, the influences of color and illuminance level of lighting appear to be dependent on the surface color of bell peppers.
