- Conceptualization of rice with low glycemic index: perspectives from the major european consumersPublication . Cabral, Diva; Fonseca, Susana Caldas; Moura, Ana Pinto de; Oliveira, Jorge; Cunha, Luís MiguelRice and cereal consumption has become a concern for consumers due to usually high glycaemic indexes (GI), which is a critical issue for a balanced and healthy diet. Therefore, the development of new products with low GI is an important target of the industry, particularly in countries with high consumption. This study assesses consumers’ perceptions about “rice” and “rice with low GI” and evaluates the effect of consumers’ rice consumption profiles through the application of a free word association technique in a structured self-administered electronic questionnaire with 256 Portuguese consumers (the European market with the highest per capita consumption of rice by far). The frequency of rice consumption was evaluated, and the consumption profile was determined through a hierarchical cluster analysis, with 9% identified as daily consumers. The response words were categorized by the triangulation technique, and the association between the word categories and dimensions, sociodemographic characteristics, and consumption profile were determined. Respondents most frequently associated “rice” with rice dishes, its sensory attributes, and nutrition, highlighting the satisfaction of nutritional and hedonic needs. Consumers revealed positive expectations in relation to the functionality of “rice with low GI”. The consumers’ rice consumption profiles, sex, age, and educational levels influenced their perception towards “rice“ and “rice with low GI”. This study provides important insights for the industry to develop a consumer-oriented, low GI rice product.
- Food fraud conceptualization: an exploratory study with Portuguese consumersPublication . Costa, Maria João; Sousa, Isabel; Moura, Ana Pinto de; Teixeira, José A.; Cunha, Luís MiguelFood fraud refers to deceptive practices conducted for economic gain, and incidents of such fraud are often reported in the media and scientific literature. However, little is known about how European consumers perceive food fraud. To address this gap, a study explored Portuguese consumers' knowledge and perceptions of food fraud using qualitative methods such as free word association and semi‐structured interviews. For this research, 340 participants were recruited, providing 911 valid words, classified into categories, major categories, and dimensions. Differences between consumers' previous exposure to food fraud and sociodemographic characteristics were explored. Additionally, other thirty‐six participants were selected and interviewed, following a semi‐structured guide. Interviews were transcribed, coded, and analyzed using a thematic analysis procedure. The results suggest that Portuguese consumers view food fraud as a morally reprehensible deception and are aware of its causes and impacts. However, not all consumers know the different forms of food fraud or the types of products vulnerable to fraud. Among the most repeated words were “deception”, “expiration date”, and “falsification”. Despite this food fraud awareness, most consumers believed they were not exposed to food fraud and stated that they do not conduct daily practices to reduce exposure to it. Following the chi‐square and Mann‐Whitney tests, significant differences (p ≤ 0.05) were identified between participants exposed and not exposed to food fraud. The study also found that consumers with higher education and self‐reported exposure to food fraud had a better understanding of the issue. This study provides insights for quantitative research on consumer perceptions and beliefs about food fraud to explore further vulnerable food categories and types of food fraud in real‐world scenarios.
- Consumers’ associations with herbal infusions and home preparation practicesPublication . Rocha, Célia; Moura, Ana Pinto de; Cunha, Luís MiguelThe consumption of infusions is affected by many factors, namely those associated with culture, health and sensory properties. The main goal of this research was to explore and understand consumers’ perceptions and behaviours regarding consumption and preparation of herbal infusions, applying a mixed methodology: the evaluation of consumers’ behaviours, assessed through direct self-reported measures, and indirect methods, such as free word association and auto-videography. A total of 489 Portuguese consumers replied to a web-based questionnaire. Based on their frequency of consumption and availability, 60 participants were selected for an observational study. Over 27% of the participants had at least a daily cup of herbal infusion, and over 74% had it at least every week. At home, participants reported the use of teapots (44.1%) or mugs/cups (52.0%) to prepare their infusions, and mostly chose bags (77.7%). Approximately 80% of the respondents removed the bags or loose leaves after steeping, mainly based on the infusion colour (53.1%). The freeword association results show that daily and weekly consumers establish a stronger connection with the sensory, emotional, health and wellbeing dimensions of the product, while less frequent consumers only consider the composition of the herbal infusion. From the observational study, it was noticeable that most of the consumers take less than one minute to steep the infusions, clearly below the four to ten minutes recommended for the most popular herbal infusions, like lemon verbena or peppermint. These results emphasize the need for communication strategies focused on the preparation process to give consumers tools to improve their sensory experience.
