  • 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.

  • The principal objective of this study was to evaluate the consumption patterns, the importance of product properties, and the satisfaction levels of blackberry and mulberry fruit beverage products(BMBPs) in the Jeonbuk area, Korea. Self-administered questionnaires were collected from 294 customers(male 40.8%, female 59.2%) residing at Jeonju in Jeonbuk area. Descriptive and comparative statistical analyses were completed using SPSS PC program(version 19.0). Approximately, 61.6% of participants consumed BMBPs 1-2times a year. Only 1.7% of participants consumed BMBPs everyday. The main information source about BMBPs was 'families/friends'. About 58.8% of participants responded that the main reason for purchasing BMBPs was 'for health'. The result indicated the overall importance level(3.94) was higher than the satisfaction level(3.41)(p < .001). The importance and satisfaction levels of the older group (50's) were significantly higher than the levels of younger group(20-30's)(p < .01 ; p < .05). According to the IPA(Importance-Performance Anslysis), 'price' and 'credibility' of companies were the most important properties that had to be changed as soon as possible to increase satisfaction with BMBPs. Therefore, to increase BMBPs'-consumption, quality improvements on these products through cooperation between BMBPscompanies, the regional government, and research institutions are necessary.
