基于消费者感知的细支卷烟轻松感、满足感设计思路   总被引:1,自引:0,他引:1  
为探索消费者感知的细支卷烟轻松感、满足感关系,通过开展不同品牌的消费者自由品吸评价试验、主流烟气检测和专家模拟消费者评吸,分析了吸烟过程的抽吸压力形成原理,探讨了消费者抽吸行为特点,归纳了与轻松感形成有关的重要因素,并提出以消费者感知为导向的细支卷烟设计理念。结果表明:①消费者感知的轻松感是与抽吸压力、烟气清爽和下咽顺畅有关的综合感受,与香气量、浓度、劲头等满足感指标存在负相关,并以刺激、余味等舒适感指标为基础。②吸阻不能真实反映消费者的抽吸压力,主流烟气的单口指标值可一定程度上表征卷烟的满足感。③在同等填充状态下,消费者感知的卷烟抽吸压力与其抽吸流量有直接关系,受产品尺寸规格、通风设计等因素制约。④以产品舒适感特征为基础,探索建立以低通风、高满足为方向的、消费者可感知的细支卷烟轻松感设计理念,适合中国消费者的细支卷烟吸食习惯。   相似文献

Mango is a popular tropical fruit and right maturity at harvest is important for eating quality and shelf life. Therefore, harvesting needs skilled pickers otherwise fruit of varying levels of maturity will be collected. This research investigated maturity classification of mango fruits (cv. Nam Dokmai) using physical, mechanical and optical properties. Variation in size, sphericity, specific gravity, total soluble solids, total acidity, surface color, acoustic response (stiffness coefficient based on the resonant frequency and the weight of the fruit), impact response (peak acceleration/corresponding time) were followed during a number of days after fruit set from 77 to 115 days. On discriminant analysis, mangoes of three maturity classes based on days after fruit set could be separated using non-destructive parameters (95%). Cluster analysis was applied based on destructive parameters (total soluble solids and total acidity) and days after fruit set to pre-allocate each fruit into four different maturity classes. The 89.0% accuracy of classification into four levels of maturity could be achieved by simplified non-destructive model. The best applicable variables of physical, mechanical and optical properties were SG, stiffness coefficient and diffuse reflectance at 670 nm, respectively.  相似文献

Market segmentation, as a technique to split a market up into segments in which consumers are as homogeneous as possible, is of great importance for companies, as it allows objective markets to be chosen for the application of differentiated marketing policies. The aim of the present work is the segmentation of the cheese market in Extremadura (SW Spain), using cluster analysis.
The data are taken from a survey of cheese consumers in Extremadura; the items of the survey are related to their cheese consumption habits, and their attitudes and preferences with respect to this product. The analysis distinguished four homogeneous consumer groups with respect to several sociodemographic and consumption behaviour variables that are of great interest for subsequent market interventions.  相似文献

Product consumption is a sensory experience that can evoke a wide range of emotional responses; and accordingly, the emotional component of food consumption has been widely addressed and has appeared in marketing literature with increasing frequency.To date, there is abundant literature on emotions elicited by product consumption, but there is little research concerning emotions and wine. In this context, we develop an emotion-based segmentation based on the emotions that consumers experience when consuming wine, both considering the valence and arousal dimensions of emotions. In addition, we profile and characterize the emotion-based obtained segments.For this purpose, an emotion-based cluster analysis is conducted through a two-step cluster procedure, followed by a MANOVA test on data from 1269 wine consumers.Our findings show that the average wine consumer does not exist, and that wine consumers cannot be seen as a homogenous group. More precisely, four clusters emerge from our results experiencing different emotions in wine consumption: “emotionally unattached”, “negatives”, “contented circumspects” and “wine lovers”. Results suggest that “wine lovers” is the most attractive segment due to their strong wine emotional bond; being the “negatives” the most challenging segment for wine makers. One useful insight for wineries is that it may not be possible to satisfy all these segments with one single wine.  相似文献

Cluster analysis is used widely to group consumers into homogenous “preference segments” from their patterns of overall liking ratings. In several case studies, cross tabulation of sample frequencies by serving orders reveals the assignment of consumers to segments may be due to the effect of serving order as opposed to genuine differences in acceptance patterns. This effect is defined as the “serving-order-by-segment effect”. To nullify this effect, four adjustment factors were developed and applied to the assessors’ data from six consumer tests. The adjustments differed in two ways: serving position and samples. Regarding serving position, two of the adjustments affected the first-serve responses only, while the other two adjustments affected the responses for all serving positions. Regarding samples, two of the adjustments used the same value to adjust the responses for all of the samples, while the other two adjustments used sample-specific values to adjust the responses for each sample. The number of samples in each of the six consumer tests varied from three to eleven. With the exception of the eleven sample study, cluster analysis on adjusted data yielded different conclusions than for non-adjusted data and results among the four adjustments varied. Serving-order-by-sample interaction plots may be useful in determining the most appropriate adjustment factor.  相似文献

BackgroundGluten- and lactose-free products are registering a sudden rise in the market, particularly among tolerant people, and this leads to consumer confusion and nutritional inadequacies. The number of studies around this trend has steadily increased in the last 10 years, as scholars from different disciplines have tried to rationalize consumers’ behaviours in these foods’ choice. However, the scientific debate appears fragmented and lacks an integrated view.ObjectivesWe conducted a systematic integrative review of consumers’ determinants of gluten-free and lactose-free consumption to frame the state of the art and research gaps.Methods45 English language articles reporting quantitative empirical studies ranging from 1971 and 2019 were analysed. First we categorized the consumption determinants in six factors applying the model proposed by Koster and Mojet, then we proposed a new integrated conceptualization inspired by Bronfenbrenner’s Transtheoretical Model. Moreover, differences and similarities between tolerant and intolerant consumers will be highlighted.ResultsResearch on intolerant consumers focused more on individuals’ determinants, in terms of awareness, trust, morality, and capability to read nutritional facts (as purchase facilitators); while studies targeting tolerant consumers focused more on objective product characteristics (with price and availability in supermarkets as barriers for consumption). In this target the subjective perspective has been studied only referring to the risk for developing psychological issues in the restrictive diet.ConclusionAs information is lacking in the scientific debate, we suggest for future research the integration of consumers’ subjective implicit levers to decipher free-from purchase behaviours.  相似文献

Consumers are being encouraged to increase the proportion of plant protein in their diets to enhance the sustainability of food systems. One approach is to develop plant-protein-rich foods that are acceptable to consumers. This study examined French people’s reactions to cheese alternatives—new fermented products that mixed animal and plant protein sources. We conducted experimental sessions with 240 French participants to assess their responses to three fermented products containing different percentages of yellow pea and cow’s milk. First, we asked the participants to blind-taste the three products and solicited hedonic scores of products. We then provided the participants with simple information about the products’ composition and asked them to taste and score the liking of the products a second time. We also asked consumers to estimate their willingness to pay (WTP) for each product before and after revealing additional information about the nutritional or environmental benefits of consuming pea-based foods. The product with the lowest percentage of pea and the highest percentage of milk received the highest hedonic scores, and WTP was correlated with the hedonic scores. The additional information about the nutritional and environmental benefits of pea-based foods led to significant increases in WTP for two of the fermented products, but not for the least preferred product, namely the one with the highest percentage of pea. This finding suggests that participant reactions to information depended on hedonic preferences.  相似文献
