In this work sensory characteristics (appearance - color, brilliance, shape and surface; texture - structure, break, firmness and chewiness; aroma - odor and taste) of dietary chocolates of different compositions were evaluated, in parallel with color parameter measurements. Color was determined instrumentally on the top and bottom surfaces, using a "MINOLTA" Chroma meter CR 400 thristimulus colorimeter. Sensory evaluation was performed by a group of experienced panelists immediately after the production (0 - 30 days), and then after 90, 180, 270 and 360 days of storage under ambient conditions (t = 18 - 20°C). Results were statistically analyzed by the two-factorial analysis of variance (MANOVA) and with the LSD - test. It was concluded that the storage time up to one year had statistically highly significant (p < 0.01) effects on the sensory attributes of chocolate, as well as on instrumentally measured color parameters.
在这项工作中,评估了不同成分的膳食巧克力的感官特性(外观-颜色、光泽、形状和表面;质地-结构、断裂、硬度和咀嚼性;香气-气味和味道),同时测量了颜色参数。使用“MINOLTA”CR-400 色度计三刺激色度计,在顶部和底部表面进行仪器颜色测定。感官评估由一组经验丰富的品评小组在生产后立即进行(0-30 天),然后在环境条件下储存 90、180、270 和 360 天后进行(t=18-20°C)。结果通过双因素方差分析(MANOVA)和 LSD 检验进行统计分析。得出的结论是,在一年的储存时间内,巧克力的感官属性以及仪器测量的颜色参数都具有统计学上的高度显著(p<0.01)影响。
