Hemp for health: a historical perspective on the marketing of cannabis-based foods in Sweden

Purpose The purpose of this paper is to provide the first comprehensive examination of the early cannabis-based food products industry, using Sweden as a case study. Drawing upon historical newspaper articles and advertisements from the Swedish Historical Newspaper Archive, the authors trace the short-lived development of the industry, from the initial exploitation of fears of tuberculosis in the late 19th century, followed by the “boom” in hempseed extract products and the widening of its claimed effects and, finally, increased skepticism and critiques of such products across the popular press in the early 20th century. Design/methodology/approach A rigorous search of the Swedish Historical Newspaper Archive was conducted to gather newspaper articles and advertisements on cannabis-based foods. The collected resources were scrutinized using critical discourse analysis to tease out key discourses at work, particularly around the concepts of health, nutrition and science. Findings The authors find that central to the marketization of cannabis-based foods was the construction of disease based on scientific and medical discourse, fearmongering to create a strong consumer base and individualization to place responsibility on consumers to take action to protect their family’s health. This demonstrates not only the long historical relationship between science and food marketing but also how brands’ health claims could often be fraudulent or overstated. Originality/value It is important to cast a historical lens on the commercialization of cannabis-based food products because demand for similar types of products has rapidly grown over the past decade. Now, just as before, manufacturers tap into consumers’ insecurities about health, and many of the same questions continue to be mooted about products’ safety. Paying greater attention to the broader and problematic history of commercial cannabis can, thus, serve as a reminder for both consumers and policymakers to think twice about whether hemp really is for health and if the claims it espouses are a mirage rather than a miracle.

Review of the facilitators and barriers to adoption of biofortified foods and food products.

Biofortification - the process of increasing the concentrations of essential nutrients in staple crops - is a means of addressing the burden of micronutrient deficiencies at a population level via existing food systems, such as smallholder farms. To realise its potential for global impact, we need to understand the factors that are associated with decisions to adopt biofortified crops and food products. We searched the literature to identify adoption determinants, i.e. barriers to (factors negatively associated) or facilitators of (factors positively associated) adoption, of biofortified crops and food products. We found 41 studies reporting facilitator(s) and/or barrier(s) of adoption. We categorised the factors using the Consolidated Framework of Implementation Research 2.0, resulting in a set of factors that enable or constrain adoption of biofortified foods across twenty-four constructs and five domains of this meta-theoretical determinant framework from implementation science. Facilitators of orange sweet potato adoption included knowledge about importance, relative advantage, efficient production and management practices; barriers included lacking timely access to quality vines and market remoteness (28 studies total). Facilitators of vitamin A cassava adoption included awareness of its benefits and access to information; barriers included poor road networks and scarcity of improved technology including inadequate processing/storage facilities (8). Facilitators of high-iron bean adoption included farmers' networking and high farming experience; barriers included low knowledge of bean biofortification (8). Barriers to vitamin A maize adoption included low awareness and concerns regarding yield, texture and aflatoxin contamination (1). These barriers and facilitators may be a starting point for researchers to move towards testing implementation strategies and/or for policymakers to consider before planning scale-up and continuous optimisation of ongoing projects promoting adoption of biofortified crops and food products.

How Do Greeks Feel about Eating Insects? A Study of Consumer Perceptions and Preferences

Edible insects are considered among the most promising sustainable sources of protein to address the predicted deficiency of conventional food protein. Due to their nutritional and environmental benefits, there is an increasing interest in the ways insects could become part of the Western diet. Little is known about Greek consumers’ attitudes toward the habit of consuming insects as food. This study provides insight into Greek consumers’ preferences for insect-based food products. The data were collected through an online questionnaire (n = 1531). A two-step cluster analysis and a categorical regression were employed to classify the respondents into discernible clusters and determine the relationship between their socioeconomic characteristics and their willingness to adopt insect-based food products. Feelings of disgust and rejection were the predominant reactions to the concept of insects as food. The acceptance of novel foods derived from edible insects could be potentially enhanced by providing information regarding their positive effects, using familiar food products, and decreasing the insect’s degree of visibility by employing processed forms. Finally, the categories of insect protein-enriched food products (bakery, meat, snacks) that Greek consumers are more likely to consume were revealed. Such findings may be useful for promoting strategies regarding consuming insect-based products.

COVID-19 and its effects on food producers: panel data evidence from Burkina Faso.

Burkina Faso implemented stringent measures in response to the COVID-19 pandemic that profoundly affected its economy and might have exacerbated food insecurity. While prior studies have assessed the impact of these measures on consumers, there is a dearth of evidence of its effects on food producers in Sub-Saharan Africa. This study aims (i) to evaluate the repercussions of COVID-19 on the possession of food production assets and on the number of livestock owned; and (ii) to determine the correlation between the food insecurity experience scale (FIES) score, ownership of these assets, and the number of livestock owned. This study employs a pre-post comparison design in two panels of randomly selected households in Burkina Faso. While Panel A was constituted of 384 households predominantly (76%) living in rural areas, Panel B comprised 504 households, only half of which (51%) lived in rural areas. All households were visited twice: in July 2019 and February 2021, for Panel A, and in February 2020 and February 2021, for Panel B. Panel B was added to the study before the pandemic thanks to additional funding; the timing of the survey was harmonized in both panels for the second round. Regression models were used with fixed effects at the household level, controlling for potential time-invariant confounding variables, and correlation coefficients between possession of production assets or number of livestock and FIES score were measured. Our findings indicate that the possession of some assets in Panel A (cart, livestock, bicycle, watch) was significantly reduced during the pandemic, as was the herd sizes among livestock-owning households in both panels. Households with fewer production assets and number of livestock were more likely to experience food insecurity. This study underscores the vulnerability of rural households in Burkina Faso to the economic disruptions caused by the COVID-19 pandemic. Addressing the challenges faced by farming and livestock-owning households is crucial for mitigating food insecurity and improving resilience in the face of ongoing crises.

Drivers of the food system based on food sovereignty domains: an integrative systematic literature review

Food sovereignty, as defined by the comprehensive definition offered in the 2007 Nyéléni Forum, encompasses essential action lines for transforming a food system based on food sovereignty principles. Understanding how current food system initiatives align with these principles is essential for identifying the necessary processes of change to drive this transformation. This study aimed to consolidate the contributions of advancements in food sovereignty to the existing literature. A systematic literature review was conducted to achieve this, analyzing 250 papers published between 2008 and 2023. The focus was on the research methods employed by the authors, food initiatives within the domains of food sovereignty, and the key drivers of a food system rooted in food sovereignty principles. The findings revealed that approximately 36% of the studies utilized interviews, surveys, and questionnaires for data collection, while 34% concentrated on targeted fieldwork through case studies. Around 19% of the studies involved in-depth interaction with specific groups, and just under 10% employed document analysis methods. The most extensively discussed domain was the use of agroecological management practices for food production, followed by the valuation of traditional knowledge, the promotion of social justice and equity, self-determination through the transformation of economic and political institutions, and the localization of food production and consumption. The food initiatives outlined overarching goals within each domain of food sovereignty, with three common goals identified across these domains: food security and consumption, environmental stewardship, and crisis preparedness. Furthermore, 29 drivers of a food system based on the domains of food sovereignty were identified, encompassing networks and a holistic approach present in all 5 domains. The study also highlights the implications for supporters of food sovereignty within the context of the identified goals of the food initiatives.

Application of 2D Extension of Hjorth’s Descriptors to Distinguish Defined Groups of Bee Pollen Images

Adulteration of food products is a serious problem in the current economy. Honey has become the third most counterfeit food product in the world and requires effective authentication methods. This article presents a new approach to the differentiation of bee pollen, which can support the development of a methodology to test honey quality based on the analysis of bee pollen. The proposed method is built on applying the Hjorth descriptors—Activity, Mobility, and Complexity—known from electroencephalography (EEG) analysis, for 2D bee pollen images. The sources for extracting the bee pollen images were the photos of honey samples, which were taken using a digital camera with a resolution of 5 megapixels connected to the tube of an optical microscope. The honey samples used were prepared according to the Polish standard PN-88/A-77626 (related to the European standard CELEX-32001L0110-PL-TXT). The effectiveness of the proposed method was positively verified for three selected groups of bee pollen—Brassica napus, Helianthus, and Phacelia—containing 35 images. Statistical analysis confirms the ability of the Hjorth descriptors to differentiate the indicated bee pollen groups. Based on the results obtained, there is a significant difference between the bee pollen groups under consideration regarding Activity p<0.00001, Mobility p<0.0001, and Complexity p<0.00001.

Knowledge, attitude and practices towards antibiotic usage among farmers rearing yaks, dzomo and hill cattle in the high-altitude regionsof Himachal Pradesh

The present cross-sectional survey aimed to investigate knowledge, attitudes and practices (KAP) of farmers of high altitude regions of Himachal Pradesh towards antibiotics and their usage. The survey was carried out using pre-validated questionnaires among 162 farmers (40 males and 122 females) engaged in animal husbandry practices particularly rearing yaks, dzomo and hill cattle from Lahaul, Spiti and Kinnaur regions of Himachal Pradesh. More than 75% of the respondents were aware of antibiotics, with females (83.6%) having more knowledge in comparison to males (52.5%). Using antibiotics in lactating animals may lead to, occurrence of antibiotics or their residues in milk, question was correctly answered by 110/162 (67.91%) respondents with significant difference with respect to educational levels. It was observed that 78.68% respondents adopted the best practice of not purchasing antibiotics without prescription. Overall, it was found that farmers’ perceptions of the use of antibiotics and their side effects are directly influenced by their education. Majority of the farmers were having significant knowledge regarding antibiotics, their usage and effects on consumers. They also had very positive attitude towards antibiotic usage but the practices were average in context of purchasing of antibiotics without prescription and consumption of milk from animals undergoing treatment. Therefore, education of farmers on food safety and antibiotic misuse becomes imperative for production of good quality animal origin foods.

Producer and Consumer Behavior towards the Consumption of Halal Food and Beverages

Introduction: Indonesia, as a country with a majority Muslim population, shows its concern for religion by consuming halal food and beverage products. Balanced consumption in Islam is implemented by avoiding tabzir and israf behavior. Objective: The method used is literature with qualitative data to describe community behavior from the producer and consumer sides when considering daily halal food and beverages. Method: The research approach used is a comparative qualitative approach. The research data was obtained from risk management reports contained in the annual reports of Bank Victoria Syariah and Bank Syariah Indonesia in 2023. Result: The result of this study is that consumers still think that halal food and beverages are only based on whether the product contains pork and dog meat and their derivatives or not. The obstacles from related agencies are moving institutions and processes that are still confusing and centralized, so there is a lack of human resources. Producer constraints are related to high costs, business management unpreparedness, and lack of socialization and awareness to register their products. Business actors' fraud against the halal label cannot be handled seriously with the policy of the halal product guarantee agency. Implication: This study increases awareness and adherence to halal standards among the public, including producers, consumers, and related institutions.

Determinants of nutrition security status of women in rural households in Northwest Ethiopia

The nutrition security of women is critically important for society’s well-being. Therefore, this study was conducted to determine the determinants of the nutrition security status of rural women in Northwest Ethiopia. Data collected from rural women in 197 randomly selected households were analyzed using a binary logit regression model. The results show that 72.6% of the women are nutritionally insecure. The determinants that significantly affect nutrition security status are family size (a negative effect), women’s daily feed frequency, milk consumption, feeding habits of fruits and vegetables, feeding habits of animal products, and women empowerment (all positive effects). The weight, height, and BMI of nutritionally insecure women were significantly lower than those of nutritionally secure women. These findings reveal the need for government and other stakeholders’ interventions to increase access to nutritious food products and to provide training on feeding culture and dietary diversity to women. The findings of this study can help the Government of Ethiopia to focus on the significant determinants to achieve its National Development Priorities focusing on the Sustainable Development Goals (SDGs) of the UN, particularly Goals 2, 3, and 5.

Abstract. Banyuwangi is one of the regions in Indonesia which is experiencing massive tourism growth. This also encourages growth in related sectors, one of which is the food industry. MSMEs in the food industry continue to grow in Banyuwangi, and the level of concern for halal-certified products continues to increase. This research aims to help optimize digitally certified halal MSMEs with the ease of submitting halal certification online. It is expected to increase the interest of MSME actors to take care of halal certification. This study uses SWOT analysis to determine the strengths, weaknesses, opportunities, and challenges for halal food products in Banyuwangi. Respondents in this study are certified Halal Companions, MSMEs in the food sector, and the Cooperative Office. Results show that the lack of information related to halal certification among business owners is one of the problems that are widely encountered. Massive dissemination of information related to halal certification to businesses through various media is suggested. In addition, meeting business owners directly is expected to minimize this gap. Keywords: MSMEs, halal certification, SWOT analysis

Hybrid paper/PDMS microfluidic device integrated with RNA extraction and recombinase polymerase amplification for detection of norovirus in foods.

HuNoV belongs to the family of Caliciviridae and is a leading cause of acute gastroenteritis that can be transmitted through contaminated foods. HuNoV causes around one out of five cases of acute gastroenteritis that lead to diarrhea and vomiting, placing a substantial burden on the healthcare system worldwide. HuNoV outbreaks can occur when food is contaminated at the source (e.g., wild mussels exposed to polluted water), on farms (e.g., during crop cultivation, harvesting, or livestock handling), during packaging, or at catered events. The research outcomes of this study expand the approaches of HuNoV testing, adding value to the framework for routine testing of food products. This microfluidic device can facilitate the monitoring of HuNoV outbreaks, reduce the economic loss of the agri-food industry, and enhance food safety.

Hardware Design Strategies Oriented to Edge Computing and AgriFood Electronics for Image Processing using Cellular Automata

There has been a growing interest from academia and industry in developing circuits and systems for edge computing and quality control tasks in food production lines, where image-processing is frequently required. This paper outlines the required considerations for designing a fruit classification system based on image-processing using Cellular Automata (CA) models and integrating it into reconfigurable hardware (HW) such as Field Programmable Gate Arrays (FPGAs). Parallel processing in CA requires numerous processing elements to be implemented and mapping CA models to HW generally comes with limitations. Homogeneous CA arrays are easier to design and implement in HW but can be resource-demanding. To fill this gap, this study explores different alternatives for the HW implementation of CA models, particularly trading computational-parallelism for a more optimized use of the available HW resources. We conducted experimental tests of the designed HW system using the Digilent Nexys development board, and the operation was validated against software-based benchmarks for image-processing, particularly concerning edge-detection. The presented study provides a broader range of design solutions for the HW implementation of two-dimensional CA models and a better understanding of their advantages and disadvantages. The results show that solutions focusing on instruction-parallelism add some complexity to the conception and require more design effort, compared to homogeneous CA models composed of identical cells. However, the instruction-parallel design solutions can significantly improve the HW resource utilization, especially when implementing computationally intensive CA rules in FPGAs.

Delimitation of Differentiated Management Units (DMUs) based on productivity maps, slope maps and vegetation indices

According to several projections, the planet's demographic density will continue to increase in the coming decades, a fact that makes it necessary to increase food production to meet population demand. However, there are factors that can make it difficult to achieve production goals, such as the high cost of inputs. Therefore, aiming to increase productivity and reduce costs through optimizing the use of resources and the area available for production, it is necessary to implement alternatives to traditional production control methods. In this aspect, precision agriculture stands out. For precision agriculture to be applied to crops, it is first necessary to observe the spatial and temporal variability of the area, through georeferenced data on the attributes that involve the production system. The correlation of these attributes can indicate sub-regions within the production areas that can receive homogeneous treatment; these fractions of the area can also be called Differentiated Management Units (DMUs). Therefore, the objective of this study was to evaluate the viability of DMU delimitations using data on productivity, slope and vegetation indices, referring to the 2020 harvest for corn cultivation. To this end, geoprocessing of the data obtained using the QGIS software was carried out, so that 3 DMUs were generated for the area evaluated in the study. Thus, the DMUs were compared with the 2021 corn harvest. The results show that the DMUs, produced with data from the 2020 corn harvest, delimited regions with different productivity data in the 2021 harvest, indicating that the possibility of obtaining better parameters in production if differentiated management were carried out in the field, and such planning can be carried out based on the assessments that DMUs allow to be carried out.

Legal Barriers in Sustainable Agriculture: Valorization of Agri-Food Waste and Pesticide Use Reduction

The transition to sustainability in agriculture faces significant challenges, especially to balance environmental goals with the practical demands of food production. This paper examines two different case studies that reveal the complexities of agricultural regulation. The first case focuses on the valorization of agri-food residual biomasses, highlighting the potential to transform food waste into valuable bioproducts such as bioenergy and biofertilizers. Despite the clear environmental and economic benefits, the absence of specific European regulations hinders the widespread adoption of these practices. Without clear rules for achieving “end-of-waste” status, the development and marketing of bio-based products remain restricted. The second case study examines the European Union’s unsuccessful effort to implement the Sustainable Use of Pesticides Regulation (SUR), which aimed to reduce pesticide use by 50% by 2030. Although the regulation sought to align agricultural practices with the EU’s Green Deal, it triggered widespread protests from farmers concerned about the potential economic losses and decreased productivity. These two cases, one showing under-regulation and the other over-regulation, highlight the need for balanced and practical regulatory frameworks that promote sustainability without imposing unrealistic demands on stakeholders. This paper ends with recommendations to harmonize regulations across Europe, ensuring that both innovation in agricultural waste management and practical pesticide reduction strategies are implemented in a way that supports farmers and producers, minimizing economic disruptions and encouraging sustainable agricultural practices.

Occupational health and safety among farmers: a comprehensive study in Central Anatolia, Turkey

BackgroundThe agricultural sector is vital for food production, economic stability, and environmental sustainability. However, it also poses significant occupational health and safety challenges due to factors such as heavy machinery usage, exposure to chemicals, and challenging environmental conditions.MethodThis cross-sectional study involved 366 farmers affiliated with the Yozgat Chamber of Agriculture in Turkey. Data on demographic characteristics, occupational factors, and work accidents were collected with interview technique between May and August 2023. While descriptive data were expressed as categories with numbers and percentages, chi-square analysis was used to compare the obtained answers with the status of having or not having a work accident. Binary logistic regression analysis was used to estimate the effect of independent variables on the probability of having a work accident.ResultsThe study revealed that 33.0% of farmers experienced work accidents in the last year. Most accidents occurred during work shifts (28.8%) and in the fall season (34.8%). Factors contributing to accidents included lack of personal protective equipment (51.5%) and transportation-related issues (36.4%). Logistic regression analysis indicated that working more than 8 h daily, working 5 days or more per week, and using bus/minibus transportation significantly increased the likelihood of experiencing work accidents.ConclusionFindings underscore the importance of implementing effective occupational health and safety measures, including proper training, provision of personal protective equipment, and improving transportation safety. Addressing these issues can enhance the well-being of agricultural workers and contribute to a safer working environment in the sector.

The Futuristic Entrepreneurial Actions for Tribal Farmers of North-east India

The North-East region of India, with its rich cultural diversity and biodiversity, is especially well-suited for agricultural growth. Given its potential, one would expect this region to be at the forefront of agri-entrepreneurial activities. Additionally, with the last few years, agriculture and its supplementary sectors became crucial components of entrepreneurial projects buoyed up by the existing need for sustainable food production, appropriate management of resources, and improving the living standards in rural areas. However, this expectation contrasts with findings from Micro, Small & Medium Enterprises (MSMEs) studies for North-East region of India. Therefore, the study aimed to identify future entrepreneurial actions in the Mishmi Hills of Arunachal Pradesh. Using an open-ended questionnaire, the researchers employed a triangulation approach to analyse potential ventures in the region. The study identified ten key entrepreneurial actions. Agro-tourism emerged as the top choice among local tribal farmers, while the commercialization of Mishmi teeta (a traditional medicinal plant) was ranked highest by experts in the region. These findings offer valuable insights for stakeholders in the region. The study highlights the entrepreneurial interests of tribal farmers and suggest areas for entrepreneurial policy development in the region. Additionally, the findings also offer actionable insights for designing training programs or policy initiatives aiming to empower tribal farmers through entrepreneurship in agricultural and allied sector.

Study on Biochemical Composition of Sea Buckthorn Fruit Cultivated from Leh, India and its Flavor Profile by Gas Chromatography Mass Spectrometry (GC-MS)

Sea buckthorn berries are among the most nutritious and vitamin rich fruit found in the plant kingdom. Biochemical composition of sea buckthorn berries cultivated from Leh, India was analyzed to study its suitability for making food products. Berry pulp was analyzed for sugars, acidity, TSS and pH. The results show that the sea buckthorn pulp exhibited higher acidity, lesser pH, total sugars and reducing sugars, when compared to fruits like pineapple and grapes. Calcium and potassium content of berry was found to be high when compared to other mineral content viz. sodium, iron and phosphorus. Antioxidant contents and antioxidant activity of pulp was determined and compared with other fruit pulps. Sea buckthorn fruit pulp exhibited significant antioxidant activity i.e. 88.72%, when compared to locally available fruits like grapes and pineapple. Totally 45 volatile flavour components were identified from sea buckthorn berry, which contains mainly esters, that contributes to significant berry aroma.

Polysaccharide-Based Bioplastics: Eco-Friendly and Sustainable Solutions for Packaging

Over the past few decades, synthetic petroleum-based packaging materials have increased, and the production of plastics has surpassed all other man-made materials due to their versatility. However, the excessive usage of synthetic packaging materials has led to severe environmental and health-related issues due to their nonbiodegradability and their accumulation in the environment. Therefore, bio-based packages are considered alternatives to substitute synthetic petroleum-based packaging material. Furthermore, the choice of packing material in the food industry is a perplexing process as it depends on various factors, such as the type of food product, its sustainability, and environmental conditions. Interestingly, due to proven mechanical, gas, and water vapor barrier properties and biological activity, polysaccharide-based bioplastics show the potential to expand the trends in food packaging, including edible films or coatings and intelligent and active food packaging. Various chemical modifications, network designs, and processing techniques have transformed polysaccharide materials into valuable final products, particularly for large-scale or high-value applications. Transitioning from petroleum-based resources to abundant bio-based polysaccharides presents an opportunity to create a sustainable circular economy. The economic viability of polysaccharide-based bioplastics is determined by several factors, including raw material costs, production technologies, market demand, and scalability. Despite their potential advantages over traditional plastics, their economic feasibility is affected by continuous technological advancements and evolving market dynamics and regulations. This review discusses the structure, properties, and recent developments in polysaccharide-based bioplastics as green and sustainable food packaging materials.

Bitter peptide prediction using graph neural networks

Bitter taste is an unpleasant taste modality that affects food consumption. Bitter peptides are generated during enzymatic processes that produce functional, bioactive protein hydrolysates or during the aging process of fermented products such as cheese, soybean protein, and wine. Understanding the underlying peptide sequences responsible for bitter taste can pave the way for more efficient identification of these peptides. This paper presents BitterPep-GCN, a feature-agnostic graph convolution network for bitter peptide prediction. The graph-based model learns the embedding of amino acids in the bitter peptide sequences and uses mixed pooling for bitter classification. BitterPep-GCN was benchmarked using BTP640, a publicly available bitter peptide dataset. The latent peptide embeddings generated by the trained model were used to analyze the activity of sequence motifs responsible for the bitter taste of the peptides. Particularly, we calculated the activity for individual amino acids and dipeptide, tripeptide, and tetrapeptide sequence motifs present in the peptides. Our analyses pinpoint specific amino acids, such as F, G, P, and R, as well as sequence motifs, notably tripeptide and tetrapeptide motifs containing FF, as key bitter signatures in peptides. This work not only provides a new predictor of bitter taste for a more efficient identification of bitter peptides in various food products but also gives a hint into the molecular basis of bitterness.Scientific ContributionOur work provides the first application of Graph Neural Networks for the prediction of peptide bitter taste. The best-developed model, BitterPep-GCN, learns the embedding of amino acids in the bitter peptide sequences and uses mixed pooling for bitter classification. The embeddings were used to analyze the sequence motifs responsible for the bitter taste.
