This study investigates barriers to consumers’ organic food purchasing. It identifies the factors and the extent to which they influence their purchase behaviours and future purchase intentions (i.e. continuance purchase intentions).

It combines qualitative and quantitative methods across two phases. Longitudinal research was carried out in two phases. It involved a thematic analysis and a covariance-based structural equation modelling approach. During Phase-1 and Phase-2, responses were collected from 376 and 351 respondents, respectively.

Phase 1 found the value barrier was significantly affecting the consumers’ purchase intention, while Phase 2 identified the impacts from both image and value barriers on purchase intentions. Notably, purchase intention affected continuance intention in both phases, while ethnocentrism showed no influence.

Using the innovation resistance theory, this study sheds light on the factors that prevent purchase intention. It offers valuable insights for policymakers and for the marketers of organic foods. This contribution implies that value and usage barriers were affecting the consumers’ purchase intentions in the short as well as in the long term. In sum, it suggests that consumers were not purchasing organic food as they felt it was either overpriced, not available in the market or because they were sceptical about its organic labelling.

Research indicated that dietary antioxidants could improve immune system performance. This study aims to investigate the association of COVID-19 symptoms, total antioxidant capacity and serum inflammatory markers, with dietary antioxidants intake among angina patients.

A food frequency questionnaire was used in a cross-sectional study among 135 angina patients with COVID-19, to assess dietary antioxidants consumption. Serum levels of tumor necrosis factor, interleukin 1ß, malondialdehyde, high-sensitivity C-reactive protein and total antioxidant capacity were measured by enzyme-linked immunosorbent assay methods.

Among study angina patients, 76.67% followed unhealthy food patterns and 23.33% followed anti-inflammatory dietary patterns before hospitalization. The angina patients with anti-inflammatory food pattern had less fever (p = 0.021), cough (p = 0.018), dyspnea (p = 0.024), diarrhea (p = 0.014) and pneumonia severity index (p = 0.014) compared to patients with unhealthy food pattern. The serum levels of tumor necrosis factor, interleukin 1ß, high-sensitivity C-reactive protein and malondialdehyde, had a significantly negative association with dietary antioxidants intake (p < 0.05).

There are significant association between antioxidant intake with serum inflammation markers in COVID-19 patients. There is a need for more clinical trial studies for approval of these results.

Environmental and health concerns are considered the most significant motivations for organic food purchasing behaviour (OFP). This study focuses on the roles of health and environmental concerns in OFP in China, aiming to explore whether there are differences in the effects and mechanisms of these two concerns.

We use the PLS-SEM to conduct empirical tests, drawing from survey data collected from 628 Chinese consumers.

The results showed that the OFP was influenced differently by health and environmental concerns. Specifically, the total effect of environmental concern on OFP outweighs that of health concern, whereas the opposite is true for direct impacts. Additionally, environmental and health concerns can influence OFP through attitude and subjective norms, although the specific mechanisms vary. Environmental concern affects OFP more through subjective norms, whereas health concern affects OFP mainly through attitude. Meanwhile, functional value quality was a significant moderator that enhanced the indirect effect of motivation on OFP.

A theoretical framework is constructed to explore the role of two types of motivations in OFP within emerging economies like China, revealing their mechanism and interaction effect with functional values.

Three-dimensional (3D) food printing is an innovative technology used to customize food products through the integration of digital technology and food ingredients. The purpose of this study is to assess the current state of research in the field of 3D food printing, identify trending topics and identify promising future research directions.

This bibliometric review systematically evaluates the field of 3D food printing using data from published literature in the Web of Science database. After reference screening, 812 articles were included in the analysis.

The result reveals that research in 3D food printing primarily focuses on the optimization and characterization of mechanical and rheological properties of food inks and that post-printing processing, such as laser treatment, has emerged recently as an important consideration in 3D food printing. However, extant works lack animal and human studies that demonstrate the functionality of 3D-printed food.

This sophisticated bibliometric analysis uncovered the most studied current research topics and the leading figures in the area of 3D food printing, providing promising future research directions.

The increasing focus of consumers on health and environmental sustainability continues to drive the demand for organic food. Despite the recognized importance of health and environmental concerns, the differential impact of these factors on organic food purchasing decisions is evident, indicating the presence of moderating variables. This investigation attempts to delineate these contingencies within the realms of socio-environmental and individual factors, paying particular attention to subjective norms, uncertainty, and egoistic values.

Using the convenience sampling method, the primary data sample was collected by a professional market research consulting firm and included 1876 usable respondents from China. Hierarchical multiple regression analysis was utilized to verify the model and test the relationships between the constructs.

The results indicated that the path from environmental concern to organic food purchase intention was significantly influenced by subjective norms and uncertainty, both of which enhance this relationship. In contrast, egoistic values appeared to dampen this effect. Uncertainty also emerged as a key factor in the link between health concerns and organic food purchase intention, albeit with an opposite impact, weakening the relationship.

This study provides useful insights for academics and marketers to understand the complex phenomenon of organic consumer behavior. This result indicates that marketers can target reference groups to develop organic food marketing strategies.

Few studies have proposed and validated a model with these moderating factors collectively to study the purchase intention of organic food consumers in China.

The purpose of this study is to explore the awareness, perception and attitude of consumers from Georgia toward smart, active and intelligent packaging of food products.

This study is based on a quantitative research method using a survey questionnaire tool to gather data from consumers in Georgia.

The scope of the sample is restricted to only one developing country. Yet, the research results are still significant in creating knowledge about innovative food packaging from different country contexts and to understanding the acceptance of intelligent active packaging by consumers.

Intelligent packaging facilitates companies with their sustainability efforts by reducing waste and environmental impact. It increases the desirability of products as responds to customer demands and leads to consumer satisfaction. Intelligent packaging can increase trust in bioproducts; for example, it is possible to track and check or monitor the origin of a product and prove that the product producer has really manufactured a bioproduct.

The study contributes to the discussion of the applicability and use of packaging with enhanced features in the food industry. In this respect, the performed pilot study fills the gap in the packaging literature by investigating consumers’ perspectives on intelligent packaging in Georgia – a non-EU, post-soviet, developing country.

This paper seeks to analyze the food and nutrition of Iran and the impact of the social elements on this system. Regards food and nutrition as a system with the following sub‐systems: production, importation, processing, storing, distribution and consumption. In relation to production, there has been a production increase in recent years, yet food shortages continue to exist. Imports of food are on the rise except for beef. Food processing is getting modernized, but traditional processing is not yet standardized. The system of food storing has deficiencies. Food distribution takes place in three different ways, though with some malfunction. Finally, regarding food consumption, there are entirely different patterns among various social classes. Suggests that food production should increase, and that there should be a reduction of food imports, a reduction of food wastages, an increase in the level of processing standards, a reduction in food shortages and better distribution of food.

An update of food irradiation developments, beginning in 1984, is provided. Differing regulations within the EEC complicate the issue, leading to the recommendation of a new strategy proposed by the Commission in a White Paper. Recent reports are described and a number of important points arose from debates within the European Parliament. Benefits to consumers and industry are weighed against possible drawbacks.

Despite public unease, certain irradiated foods will be legally on sale in the UK in 1990. The irradiation process is outlined and its applications described. At present 36 countries have legalised the process and more than 40 different foods are treated. Although the process has as yet no detection method, all products so treated will be identified. The main initial application in the UK will probably be spices and herbs, whose decontamination is currently problematic.

Until recently, the Croatian public has been relatively indifferent and unaware of issues related to genetically modified (GM) food products. However, the situation has changed and the Croatian public is becoming deeply sceptical about the benefits of GM food, and also generally about the food they eat. This paper examines some of the dimensions of the attitudes of the Croatian population toward GM food, and points out the high level of knowledge about biotechnology, and also the high level of non‐acceptance in this regard. These findings are significant for Croatian trade (especially importing and exporting), since knowledge about population preferences may influence the status of the Croatian food industry, as well as foreign food producers.
