Sensory evaluation is recognized as a useful and indispensable means in food research. To understand the present state of sensory evaluation in food science and technology in Japan, fifty five 55 research papers reporting sensory evaluation data, published in Vols. Comparing with those 77 papers of Vol.
In addition to tests of "analytical" and " affective" types, two major classifications of sensory evaluation, tests of "grading" type have been equally adopted, especially in this journal.
In any type of tests, the so-called "rating-scale" method has been most frequently applied both in this journal and in JFS. Paired comparison is used in some reports in this journal, but never in JFS. On the other hand, magnitud estimation is used in some cases in JFS but never in this journal.

Print ISSN : When a non-industrial product is brought into the laboratory or testing context, it deforms much more than an industrial product: it is not a context-free product, an acultural organic mass, but a food to which subjects have relationships shaped by individual, social, and cultural contexts. Even critics that highlight problems with context in sensory science in general e. As a result, the fact that this dichotomy stems from a particular aspect of industrial production has been so far unaddressed.
Sensory Evaluation of Food: Principles and Practices. Any adverse reactions occurring during a test must be reported and long-term studies must be monitored for any developing adverse effects. Food Quality and Preference, 30, However, even with the availability of these products on the market, diet-related health problems are still increasing. Information gathered can be used to build improved models of food choice. Includes access to current, high-quality scientific information and capabilities for exploring substructures and reactions. The challenge is to provide a sustainable and secure supply of good quality food.
I call these, respectively, assumptions of homogeneity and contextual portability, because, as discussed above, they are not explicitly guaranteed or created by sensory scientists in practice. Instead, they are assumed to be fundamental features of food production.
As also noted above, however, they are only fundamental features of industrial food production, and in fact are mostly atypical of non-industrial food production practice. However, because sensory science is deeply invested in concepts of objectivity and epistemological rigor, when sensory evaluation of artisan foods contradicts the experience of ordinary consumers, it is the consumers who are assumed to be irrational or self-deceiving e.
This common conclusion itself should be evidence enough that there is some misfit between the methodologies and the phenomena of interest. Here I present a necessarily brief summary of empirical research that I have conducted to understand the success of artisan cheesemaking in Vermont.
This research integrates sensory-science methodology — focus-group work and novel consumer-product profiling and acceptance — with social theories of human sensory behavior Hennion , ; Lave ; Shapin , instead of the strictly psychophysical.
The results are telling: in artisan products, consumers taste both intrinsic and extrinsic qualities, calling into question some of the fundamental disciplinary assumptions of sensory science. Sensory scientists have increasingly become interested in the effects of extrinsic properties e.
To make matters more complicated, American cheesemaking in general lacks the cultural patrimony that tends to promote coherent traditional practice in European cheesemaking Paxson ; there are not protected-name categories for products as in Europe Barham ; Guy Instead, American cheesemakers tend to invent their own style of cheese, often inspired by but intentionally different from any other cheese being made Paxson , ; West et al. Perhaps these consumers are biased — they have become convinced that of some external claim about how these cheeses should taste, and are reporting their sensory perceptions in ways that confirm this position and avoid cognitive dissonance — or perhaps they are in some way tasting these extrinsic properties.
I was curious whether there was evidence for the latter explanation, and designed sensory-science research that would give some insight into this question.
Given the increasing evidence that indicates, due to the complex, integrative nature of sensory perception, it is entirely possible to consider a taste of and for non-material, extrinsic properties e. In the focus groups, participants were asked to describe their experiences with and the sensory properties of Vermont artisan cheese. I was able to synthesize a set of generalizable properties that consumers used to construct these experiences, and these properties were both intrinsic e.
Their validity was reinforced by triangulation with previous work with artisan cheese producers, in which the producers used similar terms in similar ways to describe their own sensory experiences Paxson , Consumers were provided with Vermont cheeses and accurate descriptions that either described the generic type of cheese e. Iaccarino et al. Thus, context and other extrinsic properties affect the actual consumption experience of these products: the taste of Vermont artisan cheeses is not fixed, but emerges in the practices of consumption.
This lacuna is not an oversight: it is simply that artisan foods have historically not been important to the food industry, and so they have not been important to sensory science. Recently, however, there has been growing public, academic, and industrial interest in understanding foods from outside the industrial paradigm, and it has become evident that, due to the particular historical contingency of sensory science, these present an unexpected difficulty to the usual disciplinary methodologies. Sensory science methods assume that the true sensory properties of a food product remain, within limits of random variation, constant across instantiations of that product and contexts that a consumer might encounter it; in contrast, artisan food products are inherently variable and are dependent on the many contexts of everyday life.
Furthermore, examinations of artisan foods and everyday sensory experiences present challenges to an even more fundamental assumption of sensory science: that there is a single set of true or valid sensory properties for each food product, and that these properties can be conclusively distinguished from so-called biasing or false properties. In fact, the empirical evidence points in the opposite direction: food sensory properties are dependent on the subject, the context, and on a myriad of factors that are obscured by paradigms of experimental control. To understand these foods, and to understand sensory experience in everyday life, sensory science must step back from historically contingent theories and practices.
What is required is first a questioning and then a relaxation of disciplinary assumptions about homogeneity, contextual invariance, and the objectivity of sensory properties.
