Consumer Attitudes and Preferences for Fresh Market Tomatoes

This study established attractive attributes and consumer desires for fresh tomatoes. Three focus groups (n = 28 participants) were conducted to explore how consumers perceived tomatoes, including how they purchased and consumed them. Subsequently, an Adaptive Choice Based Conjoint (ACBC) survey was conducted to understand consumer preferences toward traditional tomatoes. The ACBC survey with Kano questions (n = 1037 consumers in Raleigh, NC) explored the importance of color, firmness, size, skin, texture, interior, seed presence, flavor, and health benefits. The most important tomato attribute was color, then juice when sliced, followed by size, followed by seed presence, which was at parity with firmness. An attractive tomato was red, firm, medium/small sized, crisp, meaty, juicy, flavorful, and with few seeds. Deviations from these features resulted in a tomato that was rejected by consumers. Segmentations of consumers were determined by patterns in utility scores. External attributes were the main drivers of tomato liking, but different groups of tomato consumers exist with distinct preferences for juiciness, firmness, flavor, and health benefits.     

EVALUATION OF PROCESSING TOMATOES FROM TWO CONSECUTIVE GROWING SEASONS: QUALITY ATTRIBUTES, PEELABILITY AND YIELD

Peelability is an important quality parameter in the selection of tomato cultivars (cvs.) for whole peeled and dice processing. Six processing tomato cvs. were evaluated in two consecutive years to examine the effects of cv., maturity and physical attributes on peelability and yield. Physical attributes of the raw tomatoes (size, weight, pericarp wall thickness, color) and processed paste quality (pH, titratable acidity, soluble solids, Bostwick consistency, serum viscosity, color) were determined. Large variations in physical attributes and paste quality were observed in selected tomato cvs. and maturities. In general, most of the attributes indicative of paste quality were more desirable at the less mature (e.g., pink) stage and declined with maturity. Statistical analysis suggests that there were significant differences in percentage of peeled tomatoes, peel index, and yields of whole peeled and diced tomatoes between two consecutive growing years.     

The influence of product knowledge on the relative importance of extrinsic product attributes of wine

The purpose of this paper is to examine the influence of product knowledge, both subjective and objective, on the relative importance of four extrinsic product attributes of wine, namely price, age, brand and region of origin. The relative importance of four product attributes is evaluated comparative to consumers’ self-reported and objectively measured knowledge of wine, using the conjoint analysis technique. The results suggest that product knowledge does influence the relative importance of extrinsic wine attributes in product evaluation, with the price of wine shown to be the dominant attribute regardless of the level of product knowledge expertise. Brand, age and region of origin received differing rankings of importance. Across all four levels of product knowledge, consumers navigate their evaluative product decisions according to the midpoint between most and least expensive wines in their consideration set. Price sensitivity appears to heavily impact consumer evaluation strategies, which serves to inform wine pricing strategies.     

Drivers of choice for fluid milk versus plant-based alternatives: What are consumer perceptions of fluid milk?

Fluid milk consumption has declined for decades while consumption of nondairy alternatives has increased. A better understanding of why consumers purchase fluid milk or nondairy alternatives is needed to assist increased sales of milk or maintain sales without further decline. The objective of this study was to determine the extrinsic attributes that drive purchase within each product category. The second objective was to determine the personal values behind the purchase of each beverage type to give further understanding why particular attributes are important. An online conjoint survey was launched with 702 dairy consumers, 172 nondairy consumers, and 125 consumers of both beverages. Individual means-end chain interviews were conducted with fluid milk consumers (n = 75), plant-based alternative consumers (n = 68), and consumers of both beverages (n = 78). Fat content was the most important attribute for dairy milk followed by package size and label claims. Consumers of fluid milk preferred 1 or 2% fat content, gallon, or half-gallon packaging, conventionally pasteurized store-brand milk. Sugar level was the most important attribute for plant-based beverages, followed by plant source and package size. Almond milk was the most desirable plant source, and half-gallon packaging was the most preferred packaging. Means-end chain interviews results suggested that maintaining a balanced diet and healthy lifestyle was important to all consumer groups. Lactose free was an important attribute for plant-based alternative consumers and consumers of both dairy and nondairy. A distinguishing characteristic of those who only drank nondairy plant-based alternatives was that plant-based beverages contributed to a goal to consume less animal products, beliefs about animal mistreatment, and perceived lesser effect on the environment than fluid milk. Unique to fluid milk consumers was that fluid milk was perceived as a staple food item. These results suggest that the dairy industry should focus on the nutrition value of milk and educating consumers about misconceptions regarding dairy milk. Future beverage innovation should include the development of lactose-free milk that is also appealing to consumers in flavor.     

The role of product familiarity and consumer involvement on liking and perceptions of fresh meat

The objective of this work was to compare consumer’s liking and perception of meat quality attributes as a function of their familiarity and involvement with fresh meat.Ninety-three meat consumers were classified on the basis of their familiarity with fresh meats. Socio-demographic differences between the clusters were found to relate to gender and age, and high familiarity (HF) consumers showed higher involvement with meat. HF consumers enjoyed consuming meat, and they associated a symbolic value to it. In addition, their liking ratings were higher than those of low familiarity (LF) consumers for both appearance and taste of three specific types of fresh meat over the course of product shelf-life. The perceived risks associated with meat consumption and product choice were similar between groups. Both consumer segments reported that the most important driver of fresh meat purchase is its appearance, while the role of extrinsic cues differed among the groups. The HF group needed more information when choosing meat. Regardless of familiarity level, liking was consistent with beef appearance as affected by storage, but the prediction of experienced sensory quality lacked consistency when the perceived intrinsic cue variation was not associated with meat freshness.     

How important intrinsic and extrinsic product attributes affect purchase decision

We simultaneously evaluated intrinsic and extrinsic product attributes by means of a choice-based conjoint experiment. A sample of 621 consumers tasted three soft drinks and chose the product most preferred. Test products were systematically varied across choice sets with respect to sweetening system, calorie reduction label, price and brand. Choice data and data on consumption patterns, attitudes and socio-demographics were analysed by a conditional logit model. This approach enabled us to model product choice as a function of one intrinsic and three extrinsic attributes and of consumer characteristics. The latter permits market segmentation of preference data. The main results showed that consumers’ preferences of sweetening systems are heavily dependent on brand information. Simulations of market shares based on the total sample reveal the preference of sugar over sweetening systems. However, in some specific consumer segments, sugar is not significantly superior to sweetening systems—indicating how useful market segmentation can be in sensory analysis.     

Explaining attention and choice for origin labeled cheese by means of consumer ethnocentrism

This study examines the relationship between consumer ethnocentrism, visual attention and choice for origin labeled cheese. It evaluates the impact of consumer ethnocentrism on preferences for domestic products, as well as, on the visual attention paid to the origin labeling during the decision-making. Using a choice experiment, this study investigates US respondents’ preferences for product attributes of cheddar cheese including country of origin (US, Mexico, Ireland), region of origin, hormone use, biodegradable packaging, and price. It provides empirical evidence that the level of consumer ethnocentrism among US consumers influences the preference for US labelled cheese and the visual attention to origin labeling. Specifically, higher consumer ethnocentrism leads to a higher preference for US cheese as compared to Irish cheese. Further, the study reveals that the level of consumer ethnocentrism affects visual attention paid to origin labeling. However, this is only the case in less complex decision situations, when there is little information on other product attributes.     

An attribute prioritization-based segmentation of the Chinese consumer market for fruit juice

Despite the enormous opportunity that the Chinese market provides for exporting companies in the food and beverage industry, little research has considered Chinese consumer decision making processes surrounding these products. This study provides an empirical investigation into how Chinese consumers prioritize extrinsic product attributes (brand, nutrition content claim, ingredient label, shelf-life, price, and manufacturing country) when making their fruit juice purchase decisions. The study illustrates that consumer decision making processes are culturally embedded by presenting a comparison of the study’s findings with the more prevalent Western-based literature on consumer decision making processes.A choice-based conjoint survey was administered to 645 Chinese participants in Hangzhou, China using the internet-based software 1000Minds. Three consumer segments were identified through cluster analysis: Health Conscious, Premium Product, and Long Product Shelf-life. The Health Conscious segment wants natural and nutritious fruit juices that have a well-known brand. The Premium Product segment is willing to pay higher prices for imported fruit juices. Compared to the other two segments, the Long Product Shelf-life segment prefers lower priced and extended shelf-life fruit juices that are more convenient to store and consume. While the three clusters were similar in their preferences for the fruit juice attributes and levels, they differed in the rank order of the attributes. These findings highlight the importance of how extrinsic product attributes are traded off by Chinese consumers when making their fruit juice purchase decisions.The identification of these Chinese consumer segments provides juice manufacturers better knowledge on the market opportunities in China and strategic guidance for effective positioning, packaging, labeling, and pricing of fruit juices. This attribute prioritization-based segmentation for the Chinese consumer market is novel and thus provides strong implications for the fruit juice industry. In addition, this paper also makes a novel academic contribution to the Chinese consumer decision making literature on food and beverage products.     

Conjoint analysis on the purchase intent for traditional fermented soy product (natto) among Japanese housewives

Abstract: The effect of sensory and extrinsic attributes on consumer intentions to purchase the Japanese traditional fermented soybean product natto was evaluated using conjoint analysis. Six attributes with 2 levels each were chosen and manipulated: price (high compared with low), the country of origin of the soybeans (domestic compared with imported), stickiness (strong compared with moderate), smell (rich compared with moderate), attached seasonings (attached compared with no attached seasonings), and the environmental friendliness of the packaging (high compared with low). A fractional factorial design was applied and 8 hypothetical product labels were produced. A sample of 479 Japanese housewives ranked these product labels based on their purchase intentions. Overall purchase intention was affected by country of origin, attached seasonings, and price; those attributes accounted for 81.0%, while the sensory attributes of the product accounted for 19.0% of purchase intents. In order to estimate market segments for the natto products based on consumer preference, a cluster analysis was performed. It identified 4 segments of consumers: 1 oriented to attached seasonings, another conscious of the price, and the other 2 oriented to origins. The behavioral and demographic characteristics of the respondents had a limited influence on segment membership. Practical Application: This research was conducted to understand how consumers valuate various sensory and nonsensory product attributes based on their assessment of the overall product in the case of Japanese fermented soy product (natto). The data of this research would be of great importance both in understanding consumer behavior and in designing strategies for product development.     

Acceptance of calorie-reduced yoghurt: Effects of sensory characteristics and product information

The main objective of this paper was to study acceptance of yoghurt with different levels of two specific sensory attributes, sweetness and richness, when corresponding information about sugar and fat content was given simultaneously with tasting. A conjoint design was applied to examine the effects of intrinsic attributes (sensory) and extrinsic attributes (health information) on acceptability and purchase probability for calorie-reduced vanilla yoghurt. Based on sensory profiling of 12 yoghurts produced according to an experimental design, four yoghurts varying in sweetness and richness were selected. In the conjoint study this sensory variation was combined with information concerning fat content and sugar content. 153 health conscious consumers participated in a blind testing and a conjoint study. Analyses of variance showed that sweetness and information about sugar content had significant effects on liking and purchase probability. The study showed that conjoint methodology was an appropriate tool to reveal effects of extrinsic and intrinsic product attributes.     

Consumers' preferences for beef in the Spanish region of Extremadura: a study using conjoint analysis

The study of consumers' preferences is of great interest in the beef sector, where the BSE crisis generated deep changes in the basic conditions of demand for meat and in the behaviour of consumers. Previous qualitative research showed that ‘price’, ‘origin’, ‘production system’ and ‘labelling’ were the main attributes affecting preferences for beef in Extremadura (SW Spain). The data were obtained by a survey carried out between February and April 2002 with a sample of 575 regular consumers of beef. Conjoint Analysis has been used to estimate the relative importance of those attributes and to determine the existence of consumer segments with similar preference profiles. Results show that the origin of the product is the most important attribute for the choice of beef, followed by quality labelling, production system and price. Three groups of consumers were identified through cluster analysis, according to their preferences for beef. Copyright © 2005 Society of Chemical Industry     

Consumers’ expectation and liking for cheese: Can familiarity effects resulting from regional differences be highlighted within a country?

Consumers’ food choices are affected by various factors whose study is of interest for food industry. This paper aims to investigate the influence of familiarity on the expectation and liking of Maroilles cheese among consumers familiar and unfamiliar with the product in France. It specifically focuses on two elements of the familiarity: consumption frequency and knowledge and studies their interactions. A hedonic test on Maroilles cheeses was carried out with 305 consumers from Lille city (familiar with Maroilles cheese) and from Angers city (unfamiliar). The test included three conditions: blind (tasting without any information), expected (no tasting, presentation of the photo of the packaging) and informed conditions (tasting + presentation of the photo of the packaging). A questionnaire was also administrated to assess their socio-demographic information, theoretical knowledge and consumption habits related to Maroilles cheeses. Results show that, as expected, Lille consumers eat more Maroilles and show higher liking scores for this cheese than Angers consumers do. Lille consumers outperform Angers consumers on their knowledge score and an interaction between the levels of knowledge and exposure is observed: Lille consumers with the higher level of knowledge have higher expectations of Maroilles cheese than Lille consumers with the lower level of knowledge. This effect is not observed with Angers consumers. Moreover, consumers familiar with Maroilles based their hedonic judgment mainly on intrinsic cues (tasting) whereas consumers unfamiliar with Maroilles are more influenced by extrinsic cues (packaging). Familiarity affects how consumers use available information to form product quality judgement.     

Influence of packaging information on consumer liking of chocolate milk

Chocolate milk varies widely in flavor, color, and viscosity, and liking is influenced by these properties. Additionally, package labels (declared fat content) and brand are some of the extrinsic factors that may influence consumer perception. The objective of this study was to evaluate the effects of packaging labels and brand name on consumer liking and purchase intent of chocolate milk. A consumer acceptance test, conjoint analysis survey, and Kano analysis were conducted. One hundred eight consumers evaluated 7 chocolate milks with and without brand or package information in a 2-d crossover design. A conjoint analysis survey and Kano analysis were conducted after the consumer acceptance test. Results were evaluated by 2-way ANOVA and multivariate analyses. Declared fat content and brand influenced overall liking and purchase intent for chocolate milks to differing degrees. A subsequent conjoint analysis (n = 250) revealed that fat content was a driver of choice for purchasing chocolate milk followed by sugar content and brand. Brand name was less important for purchase intent of chocolate milk than fat or sugar content. Among fat content of chocolate milk, 2 and 1% fat level were most appealing to consumers, and reduced sugar and regular sugar were equally important for purchase intent. Kano analysis confirmed that fat content (whole milk, 1, or 2% fat chocolate milk) was an attractive attribute for consumer satisfaction, more so than brand. Organic labeling did not affect the purchase decision of chocolate milk; however, Kano results revealed that having an organic label on a package positively influenced consumer satisfaction. Findings from this study can help chocolate milk producers as well as food marketers better target their product labels with attributes that drive consumer choice of chocolate milk.     

The relative influence of packaging,labelling, branding and sensory attributes on liking and purchase intent: Consumers differ in their responsiveness

The relative impact of several extrinsic attributes on informed hedonic liking and purchase intent for wine is measured by combining a blind hedonic test with an informed tasting of the same wine packaged in different product concepts. This study separated the relative effect of various attributes and also considers differences between consumers in their responsiveness to various product cues.Five-hundred and twenty-one regular wine consumers participated in a central location test in three German cities in 2005. Respondents first rated hedonic liking of a white wine in a blind condition, then evaluated elements of product concepts differing in four extrinsic attributes, region of origin, grape variety, brand and packaging style, before indicating their liking and purchase intent in an informed condition.Overall, label style and brand evaluation were the strongest drivers for informed liking followed by liking in the blind condition. Purchase intent was influenced directly only by informed liking and price evaluation; the effect of the extrinsic and intrinsic cues is mediated through informed liking. A latent class regression resulted in three consumer segments that differ in the responsiveness of their informed liking to the different product characteristics. Younger inexperienced consumers utilised a mix of various cues, wine experienced consumers based their evaluation mainly on grape variety and blind hedonic liking, and older frequent wine consumers were influenced most strongly by brand and packaging. These findings provide insights into the relative impact of product packaging, branding and labelling on overall product liking and indicate strong differences in how consumers respond to different product characteristics.     

Mapping determinants of purchase intent of concentrated yogurt (Labneh) by conjoint analysis

The relative contributions of sensory properties, fat content, price, method of processing, and presumed absence of preservatives in the product to purchase intents of concentrated yogurt (Labneh) were evaluated by conjoint analysis. Three hundred subjects tasted Labneh samples identified by different combinations of attribute levels and rated their intents to purchase the products. Analysis of the subjects’ responses revealed preference for higher levels of fat in the product and that purchase intents are largely dominated by sensory properties and fat contents. Fat levels and sensory properties accounted for 65.46% while price, method of processing, and presumed absence of preservatives in the product contributed for 34.54% of purchase intents. Cluster analysis identified four segments of consumers with similar preferences for sensory properties and fat levels and response to presumed absence of preservatives in products. Apart from the product purchased/consumed by respondents, behavioral and demographic characteristics of subjects were not related to segment membership. Information on fat levels and other extrinsic attributes of the product have secondary effects on purchase decisions of concentrated yogurt when evaluated by conjoint analysis models incorporating actual tasting of products in the study design. Actual tasting of products masked possible effects of behavioral and demographic characteristics of respondents on purchase intents of Labneh.     

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.     

Attitude-behaviour dissonance regarding the importance of food preservation for customers

The aim of the study was to identify the importance of individual food product attributes (the use of preservatives, processing method, shelf-life period and nutritional value) as well as their relation to the purchase behaviour. To achieve this, consumer preferences were decomposed in conditions of full access to information, and data was compared with actual consumer behaviour related to making purchasing decisions in front of the store shelf. Based on data from 338 respondents, conjoint analysis and repeated ANOVA measurements were carried out, allowing to eliminate individual behavioural patterns. The results showed a dissonance between the consumers attitudes towards the attributes and their shopping behaviour. The processing method was the most important declared attribute for consumers, meanwhile this information was the least searched for during purchase. At the same time, shelf-life period marked as the least important was the main information searched for by consumers when shopping. The results also show a clear dislike towards the use of microwaves as a preservation method, while traditional thermal preservation was marked as the most positive for consumers. In addition, consumers were classified into 3 heterogeneous groups, identifying differences in the preferences of food attributes. The obtained results have practical value relating not only to the preferences of individual attributes, but also to their various variants. The results can be a guide for companies to properly label food products. The indicated dissonance illustrates the educational gap and related insufficient motivation to get to know the product before buying it. This is extremely important in connection with technological development and new food processing methods.     

An Investigation of Some Important Storage Parameters in Acidified Bulk Storage of Tomatoes

Acidified bulk storage of tomatoes at a pH of approximately 1.3 was used to store whole tomatoes without spoilage for up to 4 months. Storage treatments of time and temperature lead to concurrent off flavor and brown color development which was presumed to be at least partially due to container oxygen permeability problems. Best quality in this study was found after storage at lowered temperatures. When unpeeled tomatoes were stored, they softened during storage and did not remain whole upon subsequent peeling. Heat peeled whole tomatoes stored in tomato juice gave the best storage quality of any treatment combinations used. The major problem experienced with this storage method was non-microbial chemical deterioration of product quality after storage.
