Steps towards a consumer-driven ‘concept innovation machine’ for food and drink

Innovation is often left to insight and serendipity. A lot of what researchers call innovation is actually a process by which one can make the individual consumer or practitioner more ‘creative’. Although it is important to work with the creative individual in hopes of coming up with the better ‘idea’ and new product/service opportunity, an equally valid albeit novel and counterintuitive approach systematizes creativity in a ‘research-driven machine’. This paper presents an approach to the systematization, based upon the point of view that creativity and innovation comprise the recombination of components into new blends. Given this point of view, to then spur innovation requires a systematic database that the user can access, with tools to help manipulate that database. The paper shows how such a database can be constructed and then used to create a novel product. The approach provides a general framework for the sensory professional to become more involved in the early stages of product development, where the focus is on the conceptual aspects of food features rather than on their physical manifestations in actual products.     

Darwinian evolution patterns in food products and beverages

Although the development and survival of food products are regulated by mechanisms that bear little resemblance to those operating in the living world, their general evolutionary patterns share certain common features. These include punctuated equilibria, convergent evolution, coevolution, the equivalence of symbiosis, and, rarely, even parasitism.

The evolution of food products, like that of living organisms and other systems, is a nonlinear process. Consequently, its path can be affected not only by major events that drastically alter the environment but also by very minor events that may be unnoticeable at the time of their occurrence.     

Processing companies' preferences for attributes of beef in Switzerland

The aim of this work was to assess processing companies' preferences for attributes of Swiss beef. To this end, qualitative interviews were used to derive product attributes that determine the buying decision. Through an adaptive-choice based conjoint analysis survey and latent class analysis of choice data, we compute class preferences. Results show that there are two distinct classes. A smaller class emphasizes traceability back to the birth farm and low producer price, a larger class focuses on environmental effects and origin. Additionally we see that larger companies are more price-sensitive and smaller companies are more sensitive to origin of the animals. The results outlined in this paper may be used to target market segments and to derive differentiation strategies based on product characteristics.     

Consumer preferences for iced coffee determined by conjoint analysis: an exploratory study with Norwegian consumers

The main aim of this study was to investigate consumer preferences for extrinsic attributes of iced coffee, explore consumers' coffee consumption habits, find new market opportunities and segment consumers based on similar products preferences. A sample of 101 consumers of iced coffee was recruited during 2012 in Norway. Twelve iced coffee products combining different levels of attributes such as coffee type, origin, calories and price were presented on screen and rated according to consumers' willingness to buy (WTB). Mixed model anova , principal component analysis (PCA) and partial least squares discriminant analysis (PLS‐DA) were applied to analyse data. Results show that the most preferred products for the consumer sample as a whole were low‐price low‐calorie products, while age has a significant effect on WTB for different iced coffee products. Four different consumer segments based on type of iced coffee and country of production preferences were identified and discussed.     

Dairy cow preferences for soft or hard flooring when standing or walking

Concrete is the most commonly used alley flooring in confined dairy herds because of its qualities of construction and ease of cleaning. Nevertheless, the hardness, abrasiveness, and slipperiness of concrete floors have adverse effects on animal well-being and health, and yielding rubber flooring is becoming popular as a way of improving the flooring conditions on walkways. The aim of this study was to investigate preferences of dairy cows for rubber compared with concrete flooring under the conditions of a commercial dairy farm. The study was conducted in an organic dairy herd with free-stall housing. Floor preference was tested on groups of standing cows in a 120-m² holding pen before milking, and 1 yr later on a 12- × 3-m walkway. The holding pen and the walkway were divided lengthwise into 2 identical sections. Two types of solid rubber mats (soft and extra soft) were tested against solid concrete in the holding pen. Slatted and solid rubber mats were tested against slatted concrete in the walkway. Each floor type was tested over 4 d on the left side and 4 d on the right side of the holding pen and the walkway, respectively. Concrete flooring on both sides of the sections was tested as a control before the testing of different section materials. All observations of the distribution of cows in the sections were made from video recordings captured in association with the afternoon milking. The number of cows on each section was recorded approximately every 7 min in the holding pen, and continuously on the walkway. A significantly higher proportion of cows stood on the side with the soft and extra soft rubber mats (65.1 ± 2.7 and 69.3 ± 2.6%, respectively, mean ± SEM) compared with the control distribution when only the solid concrete was available (50.9 ± 3.9%). A significantly higher proportion of nonlame cows walked exclusively on the side with the slatted (64.5 ± 5.4%, d 4) or solid rubber mats (68.2 ± 5.1%, d 4) compared with controls (28.9 ± 4.3%). Lame cows within a group of walking cows did not show a higher preference for soft flooring as distinct as nonlame cows (52.7 ± 6.9 and 59.4 ± 6.2% for the solid and slatted rubber mats, respectively, at d 4 vs. 40.3 ± 6.2% for control), presumably because of competition with other, higher ranked cows. It was concluded that the majority of cows preferred to walk and stand on soft rubber rather than on concrete flooring.     

A Preference Study for No Alcohol Beer in Italy Using Quantitative Concept Analysis

The aim of this paper is to understand the consumer's attitude towards alcohol free beers in Italy by using a quantitative concept analysis. The method uses conjoint analysis with consumers of Italian beer, living in different geographical areas. Results show that packaging (RI = 56.24%) is the main attribute considered, followed by price, flavour, claims and colour. As far as part‐worths are concerned, glass and twist‐off caps are the utilities that most increase the preference. They are followed by malty and fruity characters, a price of less than 0.80 Euros, a remarkable body and intended for young adults. In contrast, plastics, a price of over 1.25 Euros, organic raw materials and imports showed the greatest negative impact on preference. These findings can be used as a base for new product development and for media communication purposes.     

Impact of nutritional claims on consumer preferences for bread with varied fiber and salt content

High consumption of bread provides a lot of salt, but it can also provide a lot of fiber to the diet. The use of labels on bread could encourage consumers to choose bread with improved nutritional value, i.e., with reduced salt and increased fiber content. The aim of the study was to explore the impact of the different nutritional information on preferences regarding bread (wheat plain roll) with reduced sodium content and bread enriched with fiber. The survey was carried out among a group of 330 adult consumers in 2015 in the southern part of Poland. The conjoint analysis design included four product attributes – two nutritional claims (“Low salt content” and “Source of dietary fiber”), fiber content, and salt content. The mean part-worth utilities of individual product attributes and the relative importance of attributes within the sample were calculated using SAS procedures. Next, cluster analysis, based on the individual utilities, was undertaken to identify groups (clusters) of consumers with similar preferences. Salt content had higher relative importance for the participants in comparison with both claims, while the relative importance of dietary fiber content was the lowest. The relative importance of both nutritional claims was almost equal, namely 25.5% for the fiber claim and 25.4% for the salt claim. The results of cluster analysis showed strong heterogeneity in consumer reactions to the attributes of the tested product. To conclude, providing information about the salt and fiber content of bread is necessary to encourage a healthy choice, but the claims placed on bread packaging seem to be insufficient as they contribute to the avoidance of the product. Increasing consumer awareness of nutrition claims of foods is required.     

Reinventing the Role of Consumer Research in Today's Open Innovation Ecosystem

Consumer research (CR) has played a key role in the food and beverage industry. Emerging from laboratory product-tests, it has evolved into a corporate testing service that measures the consumer reactions to products/concepts using a wide range of analyses/metrics. We propose that CR transform itself in light of accelerated knowledge expansion, mounting global, and local economic pressure on corporations and changing consumer needs. The transformation moves from its traditional testing into creating profoundly new knowledge of the product and understanding of the corporation's current and future customers. CR's tasks will involve: contributing/expanding science, applying open innovation principles, and driving consumer-centric innovation. We identify seven paradigm shifts that will change CR, namely: a different way of working—from testing to open sourcing; from good corporate citizen to change leader; open new product development (NPD) process; new management roles/cultures; universities and industry, new education curricula, and cooperation; from battle over control to sustainable sharing is winning model (SiW); and the central role of design. This integrative, innovative CR requires the implementation of three recommendations: start the change process now, fine-tune along the way; create a new marketing/CR department; and educate and professionalize. These recommendations provide the blueprint for jump-starting the process and call for immediate actions to deal with the severity of the crises facing the CR profession.     

Consumer preferences for fresh tomato at the European scale: a common segmentation on taste and firmness

Although tomato flavor has not been a major goal for breeders, nowadays it becomes important as it is a subject of consumer complaint. A better knowledge of tomato consumer preferences, at the European level, should provide the basis for improvement of fruit quality and for market segmentation. In the framework of a large European project, 806 consumers from 3 countries, The Netherlands, France, and Italy, were presented with a set of 16 varieties representing the diversity of fresh tomato offer in order to evaluate their preferences. In parallel, sensory profiles were constructed by expert panels in each country. Preference maps were then constructed in each country revealing the structure of consumer preferences and allowing identification of the most important characteristics. Then a global analysis revealed that preferences were quite homogeneous across countries. This study identified the overall flavor and firmness as the most important traits for improving tomato fruit quality. It showed that consumer preferences from different European countries, with different cultures and food practices, are segmented following similar patterns when projected onto a common referential plan. Moreover, the results clearly showed that diversification of taste and texture is required to satisfy all consumers' expectations as some consumers preferred firm tomatoes, while others preferred melting ones and were more or less demanding in terms of sweetness and flavor intensity. Detailed comparisons also showed the importance of the fruit appearance in consumer preference.     

Consumer preferences for new fermented food products that mix animal and plant protein sources

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.

Rapid quantitative method for total brominated vegetable oil in soft drinks using ion chromatography

A simple, quantitative and rapid method for total brominated vegetable oil (BVO) using ion chromatography (IC) with suppressed conductivity detection was developed and successfully applied to soft drinks with results expressed as inorganic bromide anion. The procedure involves extraction of BVO with diethyl ether and treatment with zinc dust in a solution of acetic acid, giving recoveries ranging between 92.5 and 98.5%. The calibration curves obtained were linear with correlation coefficients (r ²) of 0.998, a coefficient of variation (CV) of less than 5% and limit of detection (LOD) and limit of quantification (LOQ) of 250 and 750?µg?l^?1, respectively. The method was successfully applied to the determination of BVO in several commercial soft drinks which were found to contain BVO in the range 1.8–14.510?mg?l^?1. The method has less sources of error compared to previously published methods.     

An integrated sustainable approach for the development of Kyoho skin functional tea

Kyoho (Vitis labruscana) skin is one of the valuable and eco-friendly agricultural waste and a potential source of phenolic compounds. Therefore, we attempted to develop Kyoho skin functional tea and evaluated its nutritional-functional properties as affected by drying temperatures (30, 40, 50 and 60 °C). Kyoho skin functional tea reported negligible protein (0.02 mg g⁻¹), fat (0.04–0.19%) and calories (0.36–0.70 cal g⁻¹). Total phenolic and flavonoid contents ranged from 0.25 to 0.56 mg GAE mL⁻¹ and 0.03 to 0.19 mg QE mL⁻¹, respectively. Kyoho skin functional tea showed functional properties including antioxidant activity (63.33–79.78%) and anthocyanins (0.25–0.34 mg per 100 mL). The sensory evaluation of Kyoho skin functional tea (dried at 40 °C) rated as acceptable (>6) with attractive colour (>6). Overall, these findings recommended the possibility of using Kyoho skin to develop functional teas, which may strengthen the global beverage industries.     

Consumer-driven product development and improvement combined with sensory analysis: A case-study for European filled chocolates

Food producers are constantly searching for ways to improve existing products and to develop new products. Quality Function Deployment (QFD) methodology was designed to help incorporate the consumer’s needs into the development and improvement of products. The House of Quality (HOQ) is the first matrix produced when QFD is applied. Although several adaptations to the HOQ have been made to make the method user-friendly for the food industry, very few industry applications can be found in the literature.This paper presents the possibilities and limitations of the HOQ for the improvement of food products based on consumer preferences, processing parameters and sensory attributes. The method is illustrated by a case-study for filled chocolates. Although the results of the case-study provide insights concerning product improvement of filled chocolates, it also reveals limitations for the application and interpretation of HOQ within the food industry. To tackle these problems, the authors propose to include fuzzy set theory when completing the planning matrix, to incorporate chain information in the HOQ, and to establish good communication between departments. With precise and appropriate application of the HOQ, it is possible for a company to produce products with high consumer preference and, thus, a high success rate.     

Note — Preliminary Applications of Response Surface Modelling to the Evaluation of Optimal Growth Conditions for Beer‐spoiling Pediococcus damnosus

Beer‐spoiling lactic acid bacteria (LAB) belong to the most harmful contaminants in the brewing industry and various rapid molecular detection methods have been introduced for the detection of these organisms. However, the enrichment cultivation steps needed prior to detection by molecular methods can extend the duration of the analytical procedure by up to several days. The use of brewery‐specific enrichment cultivation media has been recommended due to the large variety within the group of LAB, as well as differences in the microbes encountered at the breweries. In contrast to using a general medium that may support only the growth of some LAB, the combination of several media could allow detection of all relevant LAB. The aim of the present study was to show the effects of shifts in the cultivation conditions and media on the growth of beer‐spoiling LAB using one of the most frequently encountered species, Pediococcus damnosus, as an example. Based on the variable analysis, significant factors could be recognized and their effects on lag‐times and growth rates were compared by means of response surface modelling.     

Use of JAR‐Based Analysis for Improvement of Product Acceptance: A Case Study on Flavored Kefirs

A common question of dairy product developments is the possible success of the new product. Several publications reported successful results using just‐about‐right (JAR) scales; although there is some debate about their advantages/disadvantages. This study highlights the limitations and opportunities of JAR scales and penalty analysis of fruit flavored kefirs. The first question is whether penalty analysis results help to improve the product and thus its overall liking (OAL)? The second question is what happens to those who rated the products “ideal” (JAR) before product development when evaluating the new products? Fruit flavored live‐flora stirred‐type kefir samples were formulated and evaluated by 92 consumers before and after the JAR‐based product development. The OAL of two products significantly increased after product development. A new visualization tool is introduced, which shows what happens to those who rated the attribute as JAR but the attribute has been modified. A general product development scheme is also introduced for JAR‐based kefir product development.
