Linking the Sensory Taste Properties of Chocolate-Based Biscuits to Consumers’ Emotions: A Cross-Cultural Study

This research measured consumers’ emotions and change in emotion to the specific sensory taste properties and attitudes of chocolate-based biscuits. The sample size involved 216 respondents from South Africa (n = 106) and Switzerland (n = 110). Respondents tasted chocolate-based biscuits and completed an online questionnaire. The increase in consumers’ levels of guilt after chocolate-based biscuit consumption and the contribution of a chocolate taste and craving attitude to consumers’ subsequent positive emotions and change in positive emotions could help food and consumer scientists to understand the link between emotions and the sensory descriptors of chocolate-based biscuits. Investigating the association between the emotional responses and sensory attributes of sweet baked products could benefit product developers when formulating food products for specific target markets and aid in the understanding of the emotional profile of food products

The utilisation of lucerne (Medicago sativa): a review

Purpose – The aim of this review is to focus on the potential utilisation of lucerne which could contribute more effectively to human nutrition and food sustainability. It aims to explore a proposed cycle for the promotion of lucerne for human consumption. Furthermore it seeks to propose lucerne as a potential vegetable and to briefly discuss the chemical composition, protein application, safety and medicinal uses of lucerne. Design/methodology/approach – A non-experimental approach, namely a systematic literature study, was used. During the study searches were done on the scientific databases Science Direct, Sabinet online, Emerald, EbscoHost and SpringerLink. Moreover internet searches were undertaken on the search engine, Google Scholar. Additionally, available textbooks and theses were consulted. Different combinations of keywords as well as synonyms for keywords were used during the searches. Some keywords used included lucerne, alfalfa and legumes. Findings – The high costs of animal protein have led to a growing interest in the industrial applications of lucerne in developing countries as lucerne is a valuable source of protein, suitable to produce nutritional food for human consumers. The full development of lucerne’s potential is hindered by a lack of awareness among consumers as well as by a lack of capacity within a research community. Therefore the key steps in the proposed cycle can be used to aid in the diversification of lucerne in the market place. Originality/value – To the author’s knowledge there exists a lack of previous reviews on lucerne. It is important for scientists to become aware of the nutritional and entrepreneurial potential and contribution for human consumption purposes in the future in order for the lucerne industry to diversify

Being Innovative in Running an Online Food Research Project in Consumer Sciences during the COVID-19 Pandemic

The COVID-19 pandemic challenged many higher education institutions to accelerate the implementation of teaching and learning through an online mode of delivery. The unpredicted shift to online learning created unprecedented challenges for Consumer Sciences students which usually perform laboratory-oriented research projects; however, any employable skills acquired during undergraduate studies should be transferable to new circumstances within different working contexts. The aim of this article is to provide educators with a basic 10-step approach to complete an online food research project and to consider students’ engagement, reflections and experiences. The article consists of three parts. The first part provides ten research steps to complete an online food research project, followed by students’ reflections of the research project. The second part presents the results on students’ online engagement with an e-learning platform. The third part presents the results of students’ experiences from the university’s student survey of the lectured module. Recommendations made from students’ reflections stimulated their higher-order thinking as they comprehended the value and importance of research, project based-learning and critical evaluation for future improvement. Educators are responsible for helping students discover their own support networks, to provide opportunities and events to share their values and work, and to motivate and encourage student engagement and reflective discussions in the online environment to stimulate higher-order thinking and enhance students’ professional and sustainable development

Consumers’ snack choices: current factors contributing to obesity

Purpose – The purpose of this paper is to indicate the need for and create an insightful understanding of the current factors contributing to consumer’s obesity levels due to their snack choices. Design/methodology/approach – This paper reports on previous literature using publications from the Emerald Insight Journals, Google Scholar, ScienceDirect and Web of Science electronic database from 1999 to 2018 that validate and support existing literature. The retrieved literature is organised and classified into specific constructs. Findings – Research into consumers’ choice of snacks from an environmental, cultural and health perspective is still underrepresented in the international scientific literature. More research is required on the specific effects of specific levels of the stated factors contributing to obesity. Health and cross-cultural studies are needed for a more comprehensive understanding of the relation between snack choices and factors contributing to obesity that will help to implement more efficient health measures. Originality/value – This paper is of value to academics studying consumers’ snacking behaviour and public health practitioners evaluating qualitative and quantitative methods to address the obesity epidemic.

Consumers’ Motives for Eating and Choosing Sweet Baked Products: A Cross-Cultural Segmentation Study

This study aimed to examine consumers’ motives for eating and choosing sweet baked products (SBPs). A cross-cultural segmentation study on a South African (SA) and Swiss population sample (n = 216), was implemented using the Motivation for Eating Scale (MFES) and the Food Choice Questionnaire (FCQ). Cluster analyses provided three consumer segments for each population sample: the balanced and the frequenters for both countries, the deniers for SA, and the health conscious for Switzerland. South Africans liked SBPs more than the Swiss respondents, however the Swiss sample consumed SBPs more often. Environmental and physical eating were the most relevant motives when eating SBPs for the SA and Swiss group, respectively. For both samples, sensory appeal was the deciding factor when choosing SBPs. Cross-cultural studies of food choices are important tools that could help improve the current understanding of factors that influence the eating behavior of ultra-processed foods to promote healthy food choices through local and global perspectives. This paper highlights that more research is needed on consumers’ motives for choosing and eating ultra-processed foods in order to develop specific integrative cultural exchange actions or intervention strategies to solve the obesity issue

Descriptive sensory analysis and consumer acceptability of lucerne (Medicago sativa L.)

Abstract : "Purpose A lack of available literature exists about sensory data on lucerne (which is mainly used for animal feed) as an underutilised protein source for human consumption in South Africa (SA). Developing tasteless lucerne products is meaningless. Therefore, the purpose of this paper is to determine the descriptive sensory profile and consumers acceptability of lucerne. Design/methodology/approach Three lucerne cultivars and one spinach beet (Beta vulgaris var. cicla L.) cultivar were used: first, to determine sensory descriptive attributes by generic descriptive analysis; and second, to determine consumers acceptance of lucerne, which were evaluated for degree of liking for aroma, taste, mouthfeel and overall acceptability with a nine–point hedonic scale. Principal component analysis of attributes for all the lucerne cultivars was applied to identify any factors differentiating between these cultivars. Findings SA Standard showed the lowest value, of the lucerne samples, for fibrous appearance, chewy and fibrous mouthfeel, bitter taste and bitter and metallic aftertaste. SA Standard was the most acceptable lucerne cultivar, indicating its application in future studies to profile new emerging cultivars. Originality/value No sensory analysis studies have been performed on South African lucerne" "cultivars to determine their sensory acceptability. These cultivars could have potential for food nutritionists, food scientists and food product developers and the commercial market
