- The Kano model of customer satisfaction provides product developers valuable information about if, and then how much a given functional requirement (FR) will impact customer satisfaction if implemented within a product, system or a service. A limitation of the Kano model is that it does not allow developers to visualize which combined sets of FRs would provide the highest satisfaction between different customer segments. In this paper, a stepwise method to address this shortcoming is presented. First, a traditional Kano analysis is conducted for the different segments of interest. Second, for each FR, relationship functions are integrated between x = 0 and x = 1. Third, integrals are inserted into a matrix crossing segments and FRs, where FRs with the highest sum across the chosen segments are identified. Finally, the functions of the chosen segments with the smallest interval, define the FRs appealing to the biggest target group. The proposed extension should assist product developers within to more effectively evaluate which FRs should be implemented when considering more than one combined customer segment. It shows which segments provide the highest possibility for high satisfaction of combined FRs. We demonstrate the approach in a case study involving customers' preference for outdoor sports equipment.

Health and quality of life in an aging population - Food and beyond

- In Europe the percentage of citizens aged 65 and over is increasing at an unprecedented rate, and is expected to account for over 30% of the population by 2050. Coupled with an increase in life expectancy, this massive demographic change calls for a major effort to ensure quality of life in our older population. A thorough understanding of the elderly as food consumers, their nutritional needs, their food perception and preferences is increasingly needed.The role of food in healthy aging was a prominent theme at the 6th European Conference on Sensory and Consumer Research, which had quality of life across the life span as a focal point. This short paper is based on a workshop held at the EuroSense meeting, focusing on research from sensory and consumer scientists. The workshop featured contributions focusing on food-related perception, needs and behavior of the elderly, and aimed at demonstrating the relevance of sensory and consumer scientists in promoting food-related well-being in an aging population. The workshop contributions are here reviewed and summarized three main themes: nutritional needs, food perception and aging, and behavioral drivers of food consumption.

Health and quality of life in an aging population : food and beyond

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In Europe, as in much of the Western world, the number of citizens aged 65 and over has grown at an unprecedented rate and is expected to account for over 30% of the total population by 2060. Coupled with a steady increase in life expectancy, this massive demographic change calls for a major effort to ensure quality of life in our older population. A thorough understanding of the elderly as food consumers, their nutritional needs, and their food perception and preferences is increasingly recognized as key areas for future research.Food perception change at a later age as a result of the psychophysiological changes that occur with aging, such as decreased appetite and chemosensory acuity. The latter generally decrease food intake and the pleasure that the elderly derive from their meals, making the identification of possible compensation strategies (e.g., flavor enhancement, textural changes, etc.) essential to food producers interested in developing products for this increasingly important segment. Promoting food satisfaction among the elderly is also paramount to ensuring adequate nutritional intake. This aspect has major public health implications, such as preventing malnutrition and sarcopenia, which are leading causes of decreased independence and lower quality of life. Additionally, the importance of social and psychological factors is increasingly recognized. Many conditions related to aging (e.g., tiredness, loneliness) may prevent elderly people from preparing and enjoying meals, calling for alternative vehicles – such as tailor-made distribution channels, social food preparation and eating situations – for promoting healthy eating.In this workshop, a range of international speakers with relevant professional experience will present their latest work. More generally, it is our intention with this workshop to raise awareness of how sensory and consumer research can contribute to promote well-being among the elderly, and ultimately to expand the number of healthy life years as we age.

Pairing coffee with basic tastes and real foods changes perceived sensory characteristics and consumer liking

- Coffee has, like wine and beer, a wide aroma spectrum, yet coffee-food pairings have not found their way into the menu of fine restaurants and the scientific literature. It is still unknown why certain beverage-food pairings are a match. The aim of this study is twofold: first, we characterize four coffees by sensory descriptive analysis (DA) where assessors evaluated samples before and after tasting aqueous solutions representing five basic tastes (BT); secondly, we investigate consumers’ liking of the same four coffees, both in isolation and when paired with a sweet or savory food.The DA results showed that exposure to all BT influenced the subsequent perceived attribute intensity of coffee; however, the direction of the effect was dependent on the BT, the coffee, and the specific sensory attribute. Most sensory attribute intensities decreased after exposure to the BT, only exposure to the BT bitter increased the intensity of more attributes than it decreased.The consumer test showed that preference for the coffee were mostly related to intrinsic characteristics of the samples as over half of the data variance in consumer liking (56%) related to the difference between samples described by fruity, floral and berry attributes, and samples described by chocolate, nutty and sweet attributes. Pairing coffee with either sweet or savory food accounted for an additional 20% of the variance in liking. Drivers of liking were sample-specific, with one common denominator: when consumers perceive the coffee as sour, they liked it significantly less. Overall, with respect to coffee-food pairing, coffee characterized as having chocolate, nutty, sweet notes are more suitable to be paired with food than coffees characterized as fruity, floral, berry.

- Multiplanet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf (V = 11.6, K = 9.9) and four transiting sub-Neptunes identified by TESS with orbital periods of 4.31, 5.90, 18.66, and 37.92 days. We collected 130 radial velocity observations with Keck/HIRES and TNG/HARPS-N to measure planet masses. We refit the 14 sectors of TESS photometry to refine planet radii (2.97 +/- 0.06 R (circle plus), 2.47 +/- 0.08 R (circle plus), 3.46 +/- 0.09 R (circle plus), and 3.72 +/- 0.16 R (circle plus)) and confirm the four planets. We find that TOI-1246 e is substantially more massive than the three inner planets (8.1 +/- 1.1 M (circle plus), 8.8 +/- 1.2 M (circle plus), 5.3 +/- 1.7 M (circle plus), and 14.8 +/- 2.3 M (circle plus)). The two outer planets, TOI-1246 d and TOI-1246 e, lie near to the 2:1 resonance (P (e)/P ( d ) = 2.03) and exhibit transit-timing variations. TOI-1246 is one of the brightest four-planet systems, making it amenable for continued observations. It is one of only five systems with measured masses and radii for all four transiting planets. The planet densities range from 0.70 +/- 0.24 to 3.21 +/- 0.44 g cm(-3), implying a range of bulk and atmospheric compositions. We also report a fifth planet candidate found in the RV data with a minimum mass of 25.6 +/- 3.6 M (circle plus). This planet candidate is exterior to TOI-1246 e, with a candidate period of 93.8 days, and we discuss the implications if it is confirmed to be planetary in nature.
