摘要
为满足自来水用水安全和高品质饮用水需求,以包装饮用水和自来水作为研究对象,通过对饮用水感官(视觉、嗅觉、味觉)关键指标比较研究,探索水质感官评价方法,并统计感官评价结果和可接受程度,得出感官评价的综合分数,通过样品间相对感官排序,最终获得样品感官评价排名.通过对包装饮用水、自来水的感官评价和水质指标的检测,筛选关键影响指标,讨论影响自来水感官评价的特定物质,如镁、钾、钙、硫酸盐、余氯等因素对水质的感官影响趋势以及感官阈值浓度,试验显示钾、钙与感官评价正相关,镁、硫酸盐和余氯与感官评价负相关.试验结果为后续提升自来水整体感官评价提供数据支持.
Abstract
In order to meet the safety of tap water and the demand for high-quality drinking water,the packaged drinking water and tap water were taken as the research objects,and the sensory evaluation methods of water quality were explored through a comparative study on the key indices of sensory perception(vision,smell and taste)of drinking water,and the sensory evaluation results and acceptability were calculated to obtain the comprehensive score of sensory evaluation.Finally,the sample sensory evaluation ranking was obtained.Through the detection of sensory evaluation and water quality indices of packaged drinking water and tap water,the key influencing indexes were screened,and the trend and sensory threshold concentration of specific substances such as magnesium,potassium,calcium,sulfate and residual chlorine that affect sensory evaluation of tap water were discussed.The test showed that potassium and calcium were positively correlated with sensory evaluation,while magnesium,sulfate and residual chlorine were negatively correlated with sensory evaluation.The experimental results provide data support for the subsequent improvement of the overall sensory evaluation of tap water.
