"Precis som vanlig köttfärs" : En kvalitativ diskursanalys av förpackningsdesign och marknadsföring av två svenskproducerade köttalternativ. / “Just Like Regular Minced Meat” : A Qualitative Discourse Analysis of Packaging Design and Marketing of Two Swedish-produced Meat Alternatives.

Dahlman, Vilma January 2022 (has links)
The food we eat has a big impact on the environment, and the global food chain is estimated to make up one third of all global emissions. In the future we will need to decrease the climate impact our food consumption has on the planet and therefore we must adjust to novel foods with a lower CO2-footprint. This thesis aims to research how two Swedish-produced novel minced meat substitute products are marketed and presented to the Swedish consumer through semiotics and discourse analysis. The visual presentation of these products’ packaging design and website information was analysed through annotated observation and interpreted through discourses based on three central themes: Swedishness, sustainability and minced meat. The analysis demonstrated that representations of all three themes are used in order to build a narrative through storytelling. The results of the analysis indicate that the central themes are used in order to convey a sense of naturalness and authenticity, as well as making the product recognisable to the consumer.

How can insect-based food appeal to consumers in the Swedish market? : A qualitative study on identifying major factors that impact purchasing insect-based food and examining how novel companies can penetrate the Swedish market.

Okutani, Daiki, Wu, Dairong January 2021 (has links)
The main purpose of this study was to examine the main factors that both positively and negatively influence consumers purchasing behavior in terms of insect-based food. By investigating the factors, the study aimed to shed light on how insect-based food can seamlessly penetrate the Swedish market with the use of marketing strategies. In order to further facilitate the study, a qualitative research with an inductive approach was selected. With the foundation of formulated questions, the semi-structured interviews were conducted to gain deeper insights in relation to the study. The interviewees included Swedish residents in the age range of 20-40 and 13 individual interviews were carried out to ensure the quality of data. The study identified some major contributing factors: sustainability, product quality and availability. These major factors, therefore, created a need for potential marketing strategies, which primarily focuses on extensive information sharing and green labelling.

Risk Assessment of Caffeine and Epigallocatechin Gallate in Coffee Leaf Tea

Tritsch, Nadine, Steger, Marc C., Segatz, Valerie, Blumenthal, Patrik, Rigling, Marina, Schwarz, Steffen, Zhang, Yanyan, Franke, Heike, Lachenmeier, Dirk W. 02 June 2023 (has links)
Coffee leaf tea is prepared as an infusion of dried leaves of Coffea spp. in hot water. It is a traditional beverage in some coffee-producing countries and has been authorized in 2020 within the European Union (EU) according to its novel food regulation. This article reviews current knowledge on the safety of coffee leaf tea. From the various ingredients contained in coffee leaves, only two were highlighted as possibly hazardous to human health, namely, caffeine and epigallocatechin gallate (EGCG), with maximum limits implemented in EU legislation, which is why this article focuses on these two substances. While the caffeine content is comparable to that of roasted coffee beans and subject to strong fluctuations in relation to the age of the leaves, climate, coffee species, and variety, a maximum of 1–3 cups per day may be recommended. The EGCG content is typically absent or below the intake of 800 mg/day classified as hepatotoxic by the European Food Safety Authority (EFSA), so this compound is suggested as toxicologically uncritical. Depending on selection and processing (age of the leaves, drying, fermentation, roasting, etc.), coffee leaf tea may exhibit a wide variety of flavors, and its full potential is currently almost unexplored. As a coffee by-product, it is certainly interesting to increase the income of coffee farmers. Our review has shown that coffee leaf tea is not assumed to exhibit risks for the consumer, apart from the well-known risk of caffeine inherent to all coffee-related beverages. This conclusion is corroborated by the history of its safe use in several countries around the world.

To What Extent EU Regulations and Consumer Behavior Have Affected the Expansion of Alternative Proteins: A Comparison of the Plant-Based and Cell-Based Meat Markets

Andersson, Josefine, Hannah, Kassidy January 2023 (has links)
Plant-based meat (PBM) fulfills the criteria set by the European Union regulations for the product to be sold in the EU and is currently a highly consumed conventional meat substitute in the region. Whereas, cell-based meat (CBM), as of July 2023, does not fulfill the criteria set by the EU regulations for the product to be legally sold in the EU. This is due to CBM companies not submitting the required Novel Food application to EFSA to recieve market approval. Therefore, CBM is currently not legally sold in the EU and not consumed in the region. This thesis analyzes the impact of EU regulations and consumer behavior, and how these factors affect the growth of the PBM and CBM markets. The restriction of the thesis, the PBM and CBM markets, has been chosen due to them being the primary forms of alternative proteins that are a more sustainable choice to conventional meat. The intention of the thesis is to bring attention to the interplay between law and business, and the implications of their interconnectedness. The thesis is written with the aspiration to answer the question; to what extent have EU regulations and consumer behavior affected the expansion of the plant and cell-based meat markets? To this end, we began with determining if the legal criteria of the regulatory framework applicable to PBM and CBM constitute equal regulatory conditions for the markets to expand in the EU. The regulatory framework referred to in the thesis is restricted to the primary legislations applicable to alternative proteins, which are the Genetically Modified Organisms (GMO) Regulation (EU) No 1829/2003, Novel Food Regulation (EU) 2015/2283, EU Food Law Regulation (EC) No 178/2002, Food Information to Consumers Regulation (EU) No 1169/2011, and EU labeling requirements. We then conducted a collection of previous research on both the PBM and CBM markets restricted to sustainability, retail market, consumer behavior, financial investment, development, and production processes and costs. Thereafter, we compared the previous research and the aforementioned EU regulations to conclude the impacts of the regulations and the differences in the legal application between PBM and CBM. We also conclude how consumer behavior impacts the growth of a market in addition to the regulatory requirements, and showcase their combined effects on the market. The results suggested that compliance with EU regulations determines if the products are authorized to be legally sold in the EU while consumer behavior influences market acceptance and the extent of growth. The key regulatory difference affecting the ability of CBM to comply and experience similar growth to PBM is the Novel Food Regulation, due to it categorizing cell-based products as novel foods. As of May 2023, no companies in the EU have submitted a Novel Food application to EFSA for CBM.

NOVEL FOOD: LA NORMATIVA DELL'UNIONE EUROPEA TRA SICUREZZA ALIMENTARE, SFIDE DELLA TECNICA E TUTELA DELL'AFFIDAMENTO / Novel food: food safety, technical challenges and protection of expectetions in the Eutopean Union law.

LA PORTA, BEATRICE 02 April 2019 (has links)
La produzione normativa degli ultimi decenni in campo alimentare permette di evidenziare come sussista una sempre crescente attenzione verso la scienza da parte del diritto e la costante tendenza della dottrina a ripensare, alla luce delle evoluzioni registrate, il legame esistente tra ambiti distinti ma legati tra loro in modo indissolubile. In una globale progressione della sensibilità del legislatore europeo verso le esigenze di garanzia del corretto funzionamento del mercato nonché di una crescente tutela del consumatore e della sua sicurezza, la normativa in materia di nuovi alimenti ha cercato di trovare un equilibrio tra la spinta innovatrice che, da anni, interessa l’intero settore alimentare e le plurime necessità di operatori e consumatori che richiedono prodotti dalle caratteristiche sempre più definite e idonee a soddisfare un ampio ventaglio di preferenze. Assumendo che “la capacità della tecnica è la potenza effettiva di realizzare indefinitamente scopi e di soddisfare indefinitamente bisogni” ben si comprende come quello dei novel food risulti essere un caso paradigmatico di incontro tra scienza, bisogni del mercato e regole giuridiche e come si sia esteso l’interesse sul tema, portando a porre interrogativi sempre più complessi anche in relazione alle modalità di regolamentazione delle novità in campo scientifico. / The last decades' lawmaking in the food field highlights the increasing attention towards science and got lawyers rethinking about the link existing between law and science. In a progression of the European legislator's sensitivity to guarantee the market as well as the food consumers and their safety, the EU legislation on novel foods has tried to balance food innovation and the multiple needs of operators and consumers who require products with increasingly more defined characteristics and suitable to satisfy a wide range of preferences. If "the capacity of the technique is the effective power to achieve goals and to satisfy needs indefinitely" is easy to understand how the novel food turns out to be a paradigmatic case of an encounter between science, market needs and juridical rules. Furthermore, the increasing interest in the food sector raises the question of which methods of regulation of scientific innovations apply.

Pressure assisted thermal sterilization: a novel means of processing foods

Wimalaratne, Sajith Kanchana January 2009 (has links)
This thesis investigates a newly developed and patented technology for its ability to inactivate spore- forming bacteria and non-spore-forming microorganisms. This new technology “Pressure Assisted Thermal Sterilization©” (PATS) is based on the theory of the thermal expansion of liquids. The efficiency of inactivating spore-forming and non-spore-forming microorganisms by PATS was compared with the thermal treatment alone. A combination treatment consisting of high pressure processing and gaseous carbon dioxide was also investigated for its ability to inactivate bacterial spores in model and real food matrices. The structural damage caused by treatments to the spores and non-spore-forming bacteria was assessed by scanning electron microscopy. Geobacillus stearothermophilus spores suspended in Milli-Q water, UHT milk and pumpkin soup, treated by PATS were found to have significantly lower decimal reduction times (D values) compared with the thermal treatment alone. Spores suspended in UHT milk were more heat resistant compared with those in Milli-Q water and pumpkin soup. Bacillus cereus spores suspended in Milli-Q water and pumpkin soup treated with PATS were more effectively inactivated compared with spores treated by the thermal treatment alone. Clostridium botulinum spores in saline buffer subjected to PATS treatment were inactivated more effectively compared with the thermal treatment alone. Overall, the results show that PATS was a better processing technique for inactivation of bacterial spores compared with thermal treatment alone. However, PATS had no added benefit in inactivating the non-spore-forming bacteria Escherichia coli and Saccharomyces cerevisiae cells compared with the thermal treatment. A shelf life study showed that B. cereus spores in pumpkin soup retained a low spore count (<5 LogCFU/mL) for approximately 40 days in 30oC storage after treatment with PATS. No additional degradation of colour pigments of pumpkin soup and model pumpkin juice was observed following PATS compared with the thermal treatment. Spore-forming microorganisms can be resistant to pressure treatment alone, which limits the application of high pressure processing (HPP). Therefore, a combination approach was investigated. The mechanism of inactivating spores by combining HPP with other treatments is that the pressure assists in spore germination. Then a secondary treatment (thermal or CO2 gas) can be used to inactivate the germinated spores. A combined application of HPP and a consecutive CO2 treatment was investigated for the efficiency of spore inactivation. Results showed that HPP (200 MPa for 30 min) followed by a CO2 treatment inactivated Bacillus subtilis 168 in nutrient broth, tomato juice and liquid whole egg by 2.5, 1.0 and 1.5 LogCFU/mL respectively. These results indicated that this technique is inadequate for practical use. Scanning electron micrographs showed that pressure processing of B. subtilis 168 and B. subtilis natto spores resulted in deformation of the spore structure. This structural deformation of spores may have been due to water absorption during HPP and subsequent release upon decompression. PATS treated G. stearothermophilus and B. cereus spores were more severely damaged compared with the same spores which underwent thermal treatment alone. However, the extent to which E. coli and S. cerevisiae cells were damaged by both PATS and thermal treatment was similar.
