Alcohol consumption is a burden to public health but little is known about the sensory performance of non-alcoholic drinks in the context of food and beverage pairings. This study investigated consumer liking and perception of taste balance of three beers (a pilsner, a wheat beer, and an IPA) in their alcoholic (AL) and non-alcoholic (NA) versions. All six beers were evaluated both alone and paired with skagenröra, a traditional Swedish shrimp salad. The results show that while the NA versions of the three beers were less liked when tasted alone, there was no significant difference in how they performed when paired with food, highlighting the potential of NA beers to promote healthier and more inclusive dining experiences. They also revealed a significant effect of gender in the liking of the pairing, with female participants liking the combinations less than male participants, although there was no gender difference in liking when the beers tasted alone. These findings contribute to the scientific literature on food pairing and have practical implications for the gastronomic and brewing industries, particularly for sommeliers interested in healthier pairing experiences.

In the pursuit of more sustainable and healthier diets, it is important to understand how the presentation and description of vegetarian meals can affect consumers' preferences and perceptions. This study investigated the influence of two tablewares (bowl and plate) and two labels ("vegan" and "plant-based") on liking, willingness to pay, and perceptions of healthiness and sustainability of a vegetarian meal in a restaurant located in the headquarters of a retail company in Stockholm, Sweden. It was found that participants perceived the meal as healthier when it was served in a bowl or labeled "vegan" than when it was served on a plate or labeled "plantbased", and no other significant association between tableware or label and other measured variables was found. These results can help researchers, restaurants, cafeterias, pastry shops, and industries understand and communicate better with consumers about healthier and more sustainable vegetarian meals. Further studies should include other food products and participants from other cultural backgrounds, as well as measure choice and intake.

Environmental sounds influence taste perception and liking of food because eating is a multisensory experience that integrates all senses. The present study investigated how a dark chocolate ganache with two different levels of added sugar was perceived when sounds corresponding to sweet and bitter tastes were played, as well as no sound. A total of 515 participants rated the balance of sweet and bitter tastes using just-about-right (JAR) and the overall liking using a hedonic scale. Results show that the bitter sound increased the perception of bitterness of both ganache and the sweet sound increased the perception of sweetness of the higher-sugar ganache. Although not always significant, both sounds had positive effects on liking, even when they exacerbated tastes already in excess and pushed them further from the ideal. These results indicate that the sounds were effective in influencing sensory perceptions of ganache, but their effects on liking did not come from taste improvement, most likely from sensory-emotional stimulation. Together with previous studies that found significant effects of sound in perception of taste, aroma, and texture, but not in liking, this study adds evidence on the importance of environmental sounds in eating contexts and propose that crossmodal effects of sound and liking are independent processes.

Research on cross-modal correspondence has revealed interesting findings regarding how sound can affect our taste/flavour perception of food. To address the issue of excess salt in a typical Westerner's diet, approximately 30% of our daily salt intake comes from bread and cereal. Taking this fact as a starting point, the present study investigates the associations between designed soundtracks as taste stimuli for salt and sensory evaluation of bread baked with two different levels of salt. Two experiments were conducted. In Experiment 1, 265 consumers were asked to match four soundtracks with basic taste words such as 'sweet', 'salty', and 'sour'. In Experiment 2, 342 consumers tasted bread while listening either to a soundtrack that had been described as 'salty' in Experiment 1 or to no sound. The consumers then evaluated their overall liking for the bread and the bread's taste balance in terms of saltiness and sourness. Our findings confirm that consumers can associate different soundtracks with different tastes and that sound can enhance a person's taste perception of salt in bread. Thus, sound can cause consumers to perceive a higher salt intensity in bread without the actual presence of more salt, or even when the salt content has been decreased. From a health perspective, certain soundtracks may hold potential for promoting a reduction in consumers' salt intake by enhancing their perception of saltiness in food.

In this paper we present a multidisciplinary approach combining technical practices with sensory data to optimize cultivation practices for production of plants using sensory evaluation and further the how it affects nutritional content. We apply sensory evaluation of plants under mechanical stress, in this case robot cultivated basil. Plant stress is a research field studying plants' reactions to suboptimal conditions leading to effects on growth, crop yield, and resilience to harsh environmental conditions. Some of the effects induced by mechanical stress have been shown to be beneficial, both in futuristic commercial growing paradigms (e.g., vertical farming), as well as in altering the plant's nutritional content. This pilot study uses established sensory methods such as Liking, Just-About-Right (JAR) and Check-All-That-Apply (CATA) to study the sensory effect of mechanical stress on cropped basil induced by a specially developed robotic platform. Three different kinds of cropped basil were evaluated: (a) mechanically stressed-robot cultivated, (b) non-stressed -robot cultivated from the same cropping bed (reference); and (c) a commercially organic produced basil. We investigated liking, critical attributes, sensory profile, and the use of a semi-trained culinary panel to make any presumptions on consumer acceptance. The semi-trained panel consisted of 24 culinary students with experience of daily judging sensory aspects of specific food products and cultivated crops. The underlying goal is to assess potential market aspects related to novel mechanical cultivation systems. Results shows that basil cropped in a controlled robot cultivated platform resulted in significantly better liking compared to commercially organic produced basil. Results also showed that mechanical stress had not negatively affected the sensory aspects, suggesting that eventual health benefits eating stressed plants do not come at the expense of the sensory experience.

Purpose - This observational study set out to investigate the effect of sensory description labels on consumer choice of apples in a grocery retail store.

Design/methodology/approach - An independent observation study was conducted in a retail grocery store setting. A total of 1623 consumers were observed over a four day period in four different sessions, each using three apple varieties (JONAGOLD, INGRID MARIE, and ELISE). Marketing strategies differed between the sessions as follows: (1) sort name labelling only, (2) sort name and sensory description labelling, (3) sort name and sensory semantic description labelling, and (4) sort name labelling and allowing consumers to taste the apples before choosing.

Findings - Consumer product choice was affected by the sensory description labels. When only the sort name was given on the label, the consumers tended to choose INGRID MARIE, which has a strong sort name. With the addition of sensory description labels, the consumer choice shifted to ELISE, which had been chosen with a low frequency when only sort name was given, but was chosen with a high frequency when sensory description labelling was used.

Research limitations/implications - The study was limited to red apples and one national market.

Practical implications - Practitioners, managers, and marketers may benefit from using proper sensory labelling as a marketing tool for various food products, such as a apples, in a grocery retail store.

Originality/value - This study shows the importance and value of sensory description label marketing for food products in grocery retail stores. Little attention has previously been paid to the research area within sensory marketing communication concerning the interplay of sensory perception of food and the formulation of marketing labels, or taste marketing. This paper also addresses the possible interaction between the disciplines of sensory and marketing science

How do we communicate a sensory experience of food? For example, we most probably would describe the sensory experience of a food product as “It was good, I liked it”, but would probably not be able to describe the sensory characteristics of the various products with some precision. It seems that sensory aspects vary in how difficult they are to express verbally (Engen 1991); we do not use the same degree of precision of taste, smell and texture as we do to vision (Meilgaard et al. 2006). It has been argued that perceptual descriptions of colours and odours are based on different organizational principles (Richardson and Zucco 1989). Colours seem to involve a lexical system that is organized in memory, while odour perception is characterized by flexibility and adaptability but with a nonverbal coding system (Engen 1987). About 400,000 odorous substances exist, and it is not clear how many of these are similar or how many classes there might be (Engen 1982). Thus, to characterize the perceived odour and flavour (in which odour is involved) is a complex task (Amerine et al. 1965). The human being is equipped with mechanisms that could guarantee that we, to some extent, perceive the same thing with our “higher” senses, vision and audition. But the “lower” senses in the oro-nasal cavity do not function with the same accuracy when it comes to how we perceive things – they rely more on learning, memories and experiences (Köster 2003). Other circumstances such as gender and age could of course also affect the ability to detect and identify different sensory properties (Richardson and Zucco 1989). Without a description of the sensory qualities, the individual profiles of the item in question could not be captured.

From a linguistic point of view, sensory studies seem to include many aspects highly relevant to different linguistic areas. Since sensory descriptions of food mainly operate with words, such as crisp, tender and nutty, including their conceptual content, lexical and cognitive semantics seem to be a fruitful approach to studying and developing sensory descriptions. But in spite of the central role of the lexicon in describing sensory qualities of food, surprisingly little attention has been paid to linguistic aspects of sensory language, which may be due to the fact that sensory studies and linguistics belong to different academic disciplines. Briefly, in sensory studies, some guidelines are usually used for words and definitions, e.g. the ISO standard and ASTM (American Society for Testing and Materials) Noble et al. (1987) created a system for aromatic flavour for wine arranged in a partly taxonomic and semantic domain-based wheel, i.e. rather general semantic domains such as “fruity” and “nutty”. The specific-general dimension in the wheel is obvious; the general “fruity” leads to the more specific “berry” and “strawberry” in the outer tier of the wheel. More recently Pickering and Demiglio (2008) used the same model for a white wine’s mouthfeel. There are a large number of studies where sensory vocabularies are discussed and developed; some recent examples are Duffrin and Pomper (2006), Carunchia Whetstine et al. (2007), Hongsoongnern and Chambers (2008) and Civille et al. (2010) regarding pawpaw fruit puree, Cheddar cheese, tomatoes and almonds respectively. However inspiring and important in sensory studies and marketing, these works are not always very systematic from a linguistic point of view. Several of the studies mentioned above use a wheel model to categorize the sensory descriptors, but as may be seen in for example Duffrin and Pomper (2006), the wheel form can make the semantic subcategorization tricky; in this “pawpaw fruit puree sensory wheel”, the words are not categorized at all except their grouping into different sensory dimensions such as texture, flavour etc. Besides, the wheel form seems to be best suited for one sensory dimension at a time, as may be seen in for example the wine aroma wheel of Noble et al. (1987). In this wheel, though, the word groups are sometimes a bit fuzzy semantically; for example, olives, asparagus and green beans are grouped together as a subcategory of “canned/cooked”, and the taxonomies are often asymmetrical in that the same word is sometimes used on several levels (for example “nutty” and “floral”, which both occupy two levels in the wheel), while the corresponding levels in other sectors show specification (“fruity” and on the next level “tropical fruit”). It may be assumed that a cross-disciplinary meeting between sensory studies and linguistics could provide interesting views leading to expanded awareness of the importance of semantics in the future development of different sensory vocabularies, as shown in a study by Swahn et al. (2010).

Avhandlingen syftar till att undersöka hur man kan utveckla ett kognitivt baserat sensoriskt språk för olika produkter i detaljhandel och därefter använda det i marknadsföringen i butiksledet. Vidare undersökts om denna marknadsföring har någon effekt på konsumenternas val av produkt. Inom forskningsprocessen, tvärvetenskapligprocess, används metodik och teorier inom sensorik, lingvistik (semantik) och marknadsföring (konsumentbeteende).

I en sensorisk studie jämfördes en tränad sensorisk panel och en grupp konsumenters förmåga att beskriva och analysera olika produkters sensoriska egenskaper. Resultatet visade på att de två gruppernas beskrivningar av de olika produkterna var relativt överensstämmande. Att beskriva smak verbalt anses som relativt svårt och komplext. Baserat på det sensoriska resultatet analyserades egenskapsorden ytterligare utifrån ett lingvistiskt perspektiv, semantik. Den semantiska analysen, empiriska resultat och teori, påvisade en möjlighet att utvinna värdefulla attribut från mer diffusa attribut, t.ex. ”nötig smak” – som kan härledas från sort, e.g. ”mandel” som i sin tur innefattar olika egenskaper i form a smak, doft, textur etc.

För att ta reda på om de sensoriska beskrivningarna hade någon effekt på konsumenternas beteende och val i butik genomfördes två empiriska studier. Konsumenternas val av produkt i butik studerades utifrån olika variabler; sensoriska beskrivningar, sensoriska och semantiska beskrivningar, sortnamn, pris, och smak preferens. Resultatet visade att de sensoriska beskrivningarna påverkade konsumenternas val av produkt, t.ex. när bara sort namn kommunicerades var man benägen att välja en känd sort, men när man använde sig av sensoriska beskrivningar skiftade konsumenternas val och de var inte längre styrda av det mer välkända sortnamnet.

Vidare visade det sig att konsumenterna vara mindre priskänslig när sensoriska beskrivningar visades. Konklusion: Användningen av ett sensoriskt språk i marknadsföringen av de undersökta livsmedlen påverkade konsumenternas val av produkt i butik samt att konsumenterna tenderade till att vara mindre priskänslig när sensoriska beskrivningar användes.
