Literature on packaged food consumption and associated factors in Kerala is limited. This study aims to find out consumption pattern of packaged food and the factors associated with it among young adults in Kerala.

The authors conducted a cross-sectional survey among 384 young adults aged 18–30 years selected using multistage cluster sampling. Information on packaged food consumption and sociodemographic factors was collected using a structured, pre-tested interview schedule. Binary logistic regression analysis was done to find out the factors associated with packaged food consumption.

Among the participants, 85.7% (95% CI = 81.9%–88.9%) reported consuming packaged food at least once a week, and 45% (95% CI = 40.4%–50.3%) reported consuming packaged food more than two times a week. Individuals who were employed [adjusted odds ratio (AOR) = 1.71, 95% CI = 1.06–2.76], who consume packaged food without a fixed routine (AOR = 2.24, 95% CI = 1.18–4.28), those without previous attempts to reduce packaged food consumption (AOR = 3.45, 95% CI = 1.72–6.91) and those who preferred packaged food for their taste and flavor (AOR = 1.73, 95% CI = 1.09–2.74) had greater odds of consuming packaged food more than two times a week compared to their counterparts.

Packaged food is frequently consumed by more than 40% of young adults in Kerala. Efforts focused on individuals (such as building awareness and taxing packaged foods) are warranted to control packaged food consumption among young adults.

This study aims to examine consumers' purchasing and consumption behavior regarding big data embedded in packaged food post-Covid-19. The second purpose is to determine whether consumer purchasing behavior varies depending on the variety and volume of big data on food packages.

Semi-structured interviews were conducted to investigate consumer sentiment regarding big embedded data in packaged foods during purchasing. Based on samples from packaged foods sold in international chain stores, interview data collected from 24 participants were subjected to systematic analytical procedures.

The results revealed that before Covid-19, consumers had positive thoughts about the expiration date, brand, and product contents but did not care much about other data. At the same time, post-Covid-19, there were changes in their attitudes and behaviors on this issue. Post-Covid-19, it has been observed that consumers have positive attitudes and behaviors toward human health and food safety issues regarding unprocessed big data in packaged foods.

This study provides a different perspective on consumer purchasing behavior through big data on packaged foods post-Covid-19. Embedded information in packaged foods provides important data regarding consumer purchasing behavior. As a powerful source of consumer sentiment, this data also provides a reference for consumer purchasing decisions.

This paper aims to examine salient issues in the packaged food business with special focus on packaging and its crucial role covering food marketing, best practices in the food and drinks industry, product innovation, food safety and quality, food supply chain management and emerging trends.

Phenomenological research has raised awareness and increased insight into critical issues in the packaged food business. The approach is based on observation of the business environment, online research, a close watch on British food industry, analysis of papers in journals, and brainstorming with co‐researchers for four years.

The research has found that the key trends fostering growth in developed packaged food markets are convenience, functionality and indulgence. The real value of packaging is that the package is an integral part of the product today. Besides, food products frequently require the general marketing approaches and techniques applied to the marketing of other kinds of products and services. In addition, for the food industry to improve further, it needs to adopt the best practices shown in this research paper. Moreover, while going for product innovation, some critical success factors must be taken into account. Furthermore, the objective of all quality assurance systems exercised by food manufacturers and processors, is to produce safe products that comply with manufacturers' specifications, including the requirements established by governments. On top of that, the companies that are the most progressive in the management of the supply chain are expected to be the most successful and profitable. Last, but not least, companies should look forward to emerging trends for business success. All these critical issues must be observed in a packaged food business for superior performance.

Company surveys have not been performed due to the limited access of the research to well‐developed Western food markets. Hence, company surveys may be the next step to further identify critical issues in the packaged food business from the perspective of existing corporations.

This paper offers a holistic view that would guide a reader to identify critical issues in packaged food in existing or new businesses.

This paper aims to address how adding food ingredients to a packaged base food affects consumers’ calorie estimation of the new augmented product.

The four performed experiments and analyses of variance demonstrate an underlying psychological mechanism, explained below.

Results show that the healthiness of the added food ingredient (AFI) does not matter if the base food is healthy, and consumers’ calorie estimates of the augmented packaged food product are accurate. When, however, the food base is unhealthy, and the AFI is healthy, consumers underestimate the new product calories. This underestimation effect increases further when the healthy ingredients multiply. This underestimation effect endures when these ingredients are presented in a visual form, but it becomes smaller when these ingredients are presented in a verbal form. A justification mechanism is relevant.

Further research should test across the broader range of the food product matrix. There is a great diversity of AFI presentations, and further research may deal with the impact of AFIs of these different forms on consumers’ calorie estimation and healthiness perceptions. Research may also test sensory-arousing mechanisms that can help understand how consumers perceive the calories of the augmented food.

The findings suggest that consumers should be cautious of the judgment bias caused by the presence of an AFI on food packages and raise their awareness regarding nutrition implications and dietary effects. From the perspective of food manufacturers, although adding healthy AFIs to unhealthy base foods may increase consumers’ purchase intention and bring higher profits, it may not be sustainable as a marketing strategy in the long term and has immediate ethical implications.

Policymakers should introduce voluntary schemes to monitor and restrict the improper presentation of AFIs, aiming to rule out the abuse of healthy AFIs on unhealthy packaged food.

This work offers three major original and valuable contributions. It explains the effects of AFIs on calorie estimation and consumer healthiness perceptions in a context not studied before, namely, packaged food products. Next, it advances the literature on consumer judgment error and heuristics concerning product package attributes. As adding ingredients is integral to product line extension decisions, the results also clarify how marketing can safeguard firm social responsibility in combating obesity.

The importance of packaging design as a vehicle for communication and branding is growing in competitive markets for packaged food products. This research utilized a focus group methodology to understand consumer behavior toward such products and how packaging elements can affect buying decisions. Visual package elements play a major role, representing the product for many consumers, especially in low involvement, and when they are rushed. Most focus group participants say they use label information, but they would like it if simplified. The challenge for researchers is to integrate packaging into an effective purchasing decision model, by understanding packaging elements as important marketing communications tools. Propositions for future research are proposed which will help in developing better understanding of consumer response to packaging elements.

This study aims to evaluate in the Portuguese population the consumption of packaged food (PF) vs non-packaged food, the associated factors and to estimate the contribution of specific food groups to the use of packaging materials.

A representative sample of the population was evaluated within the National Food, Nutrition and Physical Activity Survey 2015–2016 (n = 5,811, 3 months-84y). Dietary data were collected by two non-consecutive food diaries (children) or 24-h recalls, using a software program which integrates FoodEx2—Food classification system. Food packaging materials were measured according to the amount of PF by linear regression. The results were analyzed considering the distribution of the Portuguese population.

The reported amount of PF was 1,530 g/person/day (57%), in which PF in plastic was the most reported (69%), mainly associated with “Non-alcoholic beverages” (38%). “Fruit and vegetables” food group is most frequently reported without a package (35%). Men consumed significantly more quantity of PF for all materials, excepted for “paperboard/paper”, but also significantly more quantity of food without a package (β = 135.3 [95%IC: 63.7; 207.0]). Children and adolescents consumed more quantity of PF in multilayer materials (β = 177.8 [95%IC: 154.8; 200.9]) and significantly less quantity of food without a package (β = −343.8 [95%IC: −408.9; −278.6]). Also, more educated people consume more food without a package (β = 106.9 [95%IC: 33.2; 180.7]).

The Portuguese population presents a large consumption of PF. Male population and adults were identified as groups with higher consumption of PF.

This research investigates the influence of package sustainability on food satiation perception.

Research hypotheses were tested through three experimental studies.

Three experimental studies show that food quality is associated to higher perceived food satiation (preliminary study); that a food packaged in a sustainable package is perceived as more satiating than the same food packaged in a non-sustainable package and that this effect is explained by the higher perceived quality triggered by the presence of a sustainable package (Study 1); and that the positive relationship between higher perceived quality and perceived satiation is verified only for healthy but not for unhealthy foods (Study 2).

The present research advances knowledge on the highly debated issue of sustainable food packages. By proposing that consumers might perceive a healthy food presented in a sustainable package as more satiating, the authors show another extrinsic packaging cue modifying consumers' perception, namely package sustainability.

The purpose of this paper is to describe a pilot study characterizing the domestic usage of food packaging (amount and type) at the household level.

Collection and detailed characterization is carried out, from a sample of Portuguese consumers, of packages used at home during a seven‐day period.

The daily intake of domestically consumed, packaged food ranged from 5 to 50 g/kgbw. The average intake value for children below 12 years old was 26 g/kgbw. Considering all packaging materials, package usage ranged from 0.1dm2/day.kgbw to 0.6dm2/day.kgbw. Packaging usage factors and food‐type distribution factors for each packaging material were estimated.

The period of packaging collection and the size of the sample limit the degree of generalized conclusions that can be drawn.

The data collected are the base for the development of a framework and could make an important contribution to the assessment of consumer exposure to substances migrating from packages into food, in this case of the Portuguese consumer.

The results achieved are analysed in relation to the current assumptions made for the safety assessment of materials in the relevant European legislation. Furthermore, the results achieved can be used in a probabilistic approach to these assessments as the distributions of values, and not only the per capita values, are known.

Environmental concern is getting increasing importance in consumer shopping decisions. Nevertheless, to date, sustainable packaged foods are not always the first option when consumers go shopping. This paper analyses how environmental concern moderates the role played by external factors – preference towards sustainable retailers and trust in sustainable producers – in determining consumer purchase intentions for sustainable packaged foods. Consumer involvement in eco-friendly labels, increasingly present in food packages, is investigated as indirectly impacting pro-environmental purchase intentions.

An online survey administered to a sample of Italian food shoppers is used for the empirical analysis. A total of 278 structured questionnaires were modelled using a structural equation modelling approach.

Findings show that producers and retailers' policies in favour of sustainability are key in determining consumers' sustainable purchase intentions. Further, coherent uses of labels and logos in light of sustainability can support consumer purchase decisions. Relevant is the influence played by the environmental concern in both supporting pro-environmental purchase intentions and in amplifying the trust in sustainable producers-purchase intentions path.

This study contributes to the literature on sustainability showing how producers and retailers may together influence consumers' pro-environmental purchase intentions. Findings extend the retail literature on the impact of producers and retailers' policies on consumers' sustainable purchases. Further, environmental concern is investigated in its moderating role on the impact of external factors on consumers' pro-environmental purchase intentions.

This paper aims to model consumers’ decision to use halal logo on packaged food products. The model primarily tests the importance of country of origin (COO) of a halal logo as an indicator for assessing credibility of a halal logo, and its relevance in consumers’ decision to use the logo in packaged food purchase.

A data set from a survey of 559 respondents from two countries was used to test eight hypotheses that were developed based on a modified theory of planned behaviour framework, using partial least squares procedures.

Halal certification logo was found to have COO effect on consumers’ evaluation during purchase decision of food items. Consumer uses information on the COO of a halal logo to assess the logo’s credibility in delivering the halal food standard. The construct, along with the constructs of religiosity and its interaction terms, subjective norms and attitude, explains consumers’ intention to consider the halal logo during packaged food purchase.

Generalization of the findings is limited to the packaged food industry and to the consumer groups surveyed in the two countries.

There is a need for marketers to recognize Muslim consumers’ sensitivity towards the origin of a halal logo in choosing the right logo for their products. Logo certifiers may want to consider adopting marketing strategies to market their certification as a credible marker of a halal food standard.

The effect of COO of halal logo and its influence on consumers’ decision to use the logo in purchase decision are new to the literature.
