Sugar reduction in beverages can contribute to reduce consumption of this nutrient and to improve the health status of the population. However, such reduction can negatively affect consumer perception. Label information can be an effective tool to increase consumer interest in sugar-reduced products. In this context, the aim of the present work was to study the influence of health/hedonic claims on consumer hedonic and sensory perception of sugar reduction in orange/passionfruit nectars under expected and informed conditions. Sugar-reduced orange/passionfruit nectars (20% and 40% reduced in added sugar) featuring different claims (none, health claim or hedonic claim) were evaluated, together with a control product without reduction. Following a between-subjects experimental design, 206 participants evaluated the nectars under two experimental conditions: (a) expected, looking at the packages, and (b) informed, looking at the packages and tasting the nectars. In each experimental condition, participants evaluated their overall liking using a 9-point hedonic scale and answered a check-all-that-apply questions related to the sensory characteristics of the nectars. Results showed that although consumers did not have negative expectations about sugar-reduced nectars, the sensory characteristics of the products were the main determinants of consumers' hedonic reaction towards the nectars. The influence of claims on consumers' perception was modulated by their hedonic sensitivity towards sugar-reduction. The hedonic claim increased overall liking of those consumers with low hedonic sensitivity towards sugar reduction, whereas it had the opposite effect on the most sensitive consumers. Results from the present work suggest that although hedonic claims hold potential for a consumer segment, care must be taken to avoid the generation of unrealistic expectations about the sensory characteristics of sugar-reduced products.
减少饮料中的糖含量可以有助于减少人们对这种营养物质的摄取,从而改善人群的健康状况。然而,这种减少可能会对消费者的感知产生负面影响。标签信息可以成为增加消费者对低糖产品兴趣的有效工具。在这种背景下,本研究的目的是研究在预期和知情条件下,健康/愉悦声称对橙汁/百香果果汁中糖减少的消费者愉悦感和感官感知的影响。评估了具有不同声称(无声称、健康声称或愉悦声称)的低糖橙汁/百香果果汁(添加糖减少 20%和 40%),以及无减少的对照产品。采用组间实验设计,206 名参与者在两种实验条件下评估了果汁:(a)预期,即查看包装,和(b)知情,即查看包装并品尝果汁。在每种实验条件下,参与者使用 9 分愉悦量表评估整体喜好,并回答与果汁感官特征相关的“全选适用”问题。结果表明,尽管消费者对低糖果汁没有负面预期,但产品的感官特征是消费者对果汁愉悦反应的主要决定因素。声称对消费者感知的影响受到他们对糖减少的愉悦敏感度的调节。愉悦声称增加了对糖减少愉悦敏感度低的消费者的整体喜好,而对最敏感的消费者则产生了相反的效果。本研究的结果表明,尽管愉悦声称对一部分消费者具有潜力,但必须小心谨慎,以免对低糖产品的感官特征产生不切实际的期望。
