Abstract
Cultured meat (also referred to as cultivated, cell-based, or cell-cultured meat) is a novel food technology that is presented as a method of meat production without reliance on large-scale industrial farming. The pro-cultured meat narrative rests, in part, on a moral foundation: cultured meat is purported to alleviate the environmental and animal welfare harms associated with farmed meat. Despite this narrative, no research has examined which moral values underpin attitudes towards cultured meat. To examine this, we surveyed 1861 participants from the United States and Germany about their moral foundations and their attitudes towards cultured meat. In line with predictions, people who more strongly endorse moral values about purity (i.e., had higher scores on the purity subscale of the moral foundations scale) held more negative attitudes towards cultured meat. However, this relationship was much more consistent among participants from the United States than participants from Germany. Against predictions, attitudes towards cultured meat were not reliably associated with the extent to which people focus on harm as a moral foundation. The latter finding was particularly surprising in light of harm-reduction narratives around cultured meat. These findings demonstrate the need for a more nuanced discussion about, and understanding of, consumer concerns around cultured meat and the values that underpin them.

Abstract
Synthetic meat made from animal cells will transform how we eat. It will reduce suffering by eliminating the need to raise and slaughter animals. But it will also have big public health benefits if it becomes widely consumed. In this paper, we discuss how "clean meat" can reduce the risks associated with intensive animal farming, including antibiotic resistance, environmental pollution, and zoonotic viral diseases like influenza and coronavirus. Since the most common objection to clean meat is that some people find it "disgusting" or "unnatural," we explore the psychology of disgust to find possible counter-measures. We argue that the public health benefits of clean meat give us strong moral reasons to promote its development and consumption in a way that the public is likely to support. We end by depicting the change from farmed animals to clean meat as a collective action problem and suggest that social norms rather than coercive laws should be employed to solve the problem.

Abstract
This study focuses on the details of consumer response to lab grown 'cultured meat (CM)', compared to meat derived from insects, plants and animals. A sample of 254 New Zealanders were interviewed. A word association exercise revealed that consumer reaction to CM was dominated by affective, rather than cognitive factors. The linkages between a general food neophobia scale, a specific CM evaluation scale and purchase intent were studied. The general neophobia scale performed poorly as a predictor, while the 19-point CM evaluation scale performed well. Reducing this scale to its seven affective components, and then to just the two key affective components did not significantly reduce the scale's predictive performance. Overall, the results of this research reveal very significant differences in preference for meat products based upon their origins. Insect protein was strongly disfavoured over all alternatives, while cultured meat was significantly disfavoured compared to more established alternatives. The implications of this for the commercialisation of CM are discussed.

Abstract
Meat is traditionally obtained by sacrificing the animals. It is considered as one of the richest sources of proteins. There is an increasing demand for meat worldwide. It may not be possible to fulfill this demand for meat in future. Therefore, there is an urgent need to find out the alternative resources for proteins requirement shortly. Clean meat production is one of the best methods to be adopted as an alternative to traditional meat. The word 'clean' signifies that we can procure meat from animals without its monstrous slaughtering. Hence, it is prepared by isolating a single cell and culturing them in controlled growth conditions and medium that mimic the in vivo condition. It is not a brand new technology, but the tools for developing clean meat that mimics real meat have been technologically advanced recently. Many companies have marketed clean meat products worldwide from last five years. And it has been observed that there are mixed responses for its acceptance by consumers. The main driving forces for clean meat production derives from the concerns over environment, animal welfare, public and consumer health aspects of animal production, use of antibiotics in the animal industries, and food security. Since it's an upcoming meat production technology, there are many hurdles and challenges like nutritional attributes, flavor, shape, and structure compared to real meat. It requires many skills and understanding of muscle stem cells' regeneration and their growth under optimized scale-up production conditions. In this paper the complete details about clean meat, types of cells, and techniques used for its production has been discussed on a lab scale.

Abstract
Cultured meat (CM) is a potential sustainable novel food. Consumers' attitude towards this product is currently under investigation but a direct comparison of the effect of different types of information on consumers' response to CM is lacking. This study aimed: 1. to compare the efficacy of different informative claims in improving attitude towards CM; 2. to verify the effect of previously studied variables on attitude towards CM. Four information types were compared (human safety; animal welfare; environmental impact; no additional information: control), each envisaging two additional claims ('Antibiotic-free' and 'Pathogen- and zoonosis-free' for human safety; 'No animal breeding' and 'No animal slaughtering' for animal welfare; '82-96% reduction of water consumption' and '99% reduction of soil usage' for environmental impact). The response variables were favour towards CM, willingness to try, willingness to purchase, and willingness to substitute traditional meat with CM. Data from 603 participants (61% females, 15-80 years old) randomly assigned to four blocks, each corresponding to one type of information, were analysed. Participants were uniform among blocks in terms of socio-demographic data, frequency of consumption of traditional meat, previous knowledge of CM, food neophobia, and disgust sensitivity. The type of information given to respondents improved favour and willingness to substitute compared to the control, without differences across blocks. The effects of the additional claims were comparable. Environmental claims unified respondents, while human safety and animal welfare claims were divisive for sex and age groups. Favour, willingness to try, willingness to purchase, and willingness to substitute were positively correlated (r 0.38-0.72) but the weak correlation between willingness to try and willingness to substitute indicates that being curious may not imply the modification of actual behaviour (traditional meat substitution). Response variables seemed not to be interchangeable. Females showed higher willingness to substitute CM to conventional meat if informed with claims related to human safety. Youngsters (under '30 years old), who are plausibly the real future target, showed higher favour towards CM if provided with information related to animal welfare and human safety. Production companies should carefully choose what additional information to provide, depending on the consumer target.

Abstract
Concerns about animal welfare and sustainable meat production are growing among consumers. The awareness of carbon emissions linked to livestock and ethical concerns have triggered interest in more sustainable meat alternatives, among which cultured meat (also known as laboratory grown meat) is a recent entry. Like any new food, the ultimate success of cultured meat depends on consumer acceptance. This study analyses the peer-reviewed literature on consumer attitudes towards cultured meat to synthesize the existing evidence and identify priorities for future research. A systematic literature review was undertaken using the Web of Science, Science Direct and Scopus databases over 2008-2020, resulting in a final number of 43 articles meeting our selection criteria. The most important factors influencing consumer acceptance/rejection of cultured meat include public awareness, perceived naturalness, and food-related risk perception. Ethical and environmental concerns prompted consumers to be willing to pay a premium price for purchasing meat substitutes, but not necessarily cultured meat. Also, food neophobia and uncertainties about safety and health seem to be important barriers to uptake of this technology. Availability of other alternatives such as plant-based meat substitutes and product features, such as price and sensory appeal, are considered determinants of consumer reception of this technology. The effect of demographic factors is mixed. More research on the interrelationships between livestock production, food security, and alternative meat products is recommended.

Abstract
This review details the core activity in cellular agriculture conducted in the UK at the end of 2019, based upon a literature review by, and community contacts of the authors. Cellular agriculture is an emergent field in which agricultural products—most typically animal-derived agricultural products—are produced through processes operating at the cellular level, as opposed to (typically farm-based) processes operating at the whole organism level. Figurehead example technologies include meat, leather and milk products manufactured from a cellular level. Cellular agriculture can be divided into two forms: ‘tissue-engineering based cellular agriculture’ and ‘fermentation-based cellular agriculture’. Products under development in this category are typically valued for their environmental, ethical, and sometimes health and safety advantages over the animal-derived versions. There are university laboratories actively pursuing research on meat products through cellular agriculture at the universities of Bath, Newcastle, Aberystwyth, and Aston University in Birmingham. A cellular agriculture approach to producing leather is being pursued at the University of Manchester, and work seeking to produce a palm oil substitute is being conducted at the University of Bath. The UK cellular agriculture companies working in the meat space are Higher Steaks, Cellular Agriculture Ltd, CellulaRevolution, Multus Media and Biomimetic Solutions. UK private investors include CPT Capital, Agronomics Ltd, Atomico, Backed VCs, and Breakoff Capital. The UK also has a strong portfolio of social science research into diverse aspects of cellular agriculture, with at least ten separate projects being pursued over the previous decade. Three analyses of the environmental impact of potential cellular agriculture systems have been conducted in the UK. The first dedicated third-sector group in this sector in the UK is Cultivate (who produced this report) followed by Cellular Agriculture UK. International groups New Harvest and the Good Food Institute also have a UK presence.

Abstract
Cellular agriculture has been considered a mechanism to enable the generation of animal protein in the laboratory. Notwithstanding, this emerging technology, still on an experimental scale, is imbued with speculations, paradoxes, and ambiguities. So, the objective of this research was to analyze how synthetic meat is considered in the scientific context from the perspective of cellular agriculture considering its trajectory and its approaches. For this, we used a systematic review of the literature with detailed analysis of 109 manuscripts and application of network analysis of co-citations and predominance. This paper has constructed a historical overview of the conceptual evolution of science concerning synthetic meat from its emergence to the present day. We also verified and categorized the research about synthetic meat into three distinct approaches: (1) environmental and health; (2) technical and economic feasibility of the production process; and (3) social and market. This research maximizes the understanding of synthetic meat and its stage of technological and economic development to make commercial production feasible. Aside from that, it has brought insights about synthetic meat and this knowledge can be used by the conventional meat industries.

Abstract
BACKGROUND Cultured meat forms part of the emerging field of cellular agriculture. Still an early stage field it seeks to deliver products traditionally made through livestock rearing in novel forms that require no, or significantly reduced, animal involvement. Key examples include cultured meat, milk, egg white and leather. Here, we focus upon cultured meat and its technical, socio-political and regulatory challenges and opportunities. SCOPE AND APPROACH The paper reports the thinking of an interdisciplinary team, all of whom have been active in the field for a number of years. It draws heavily upon the published literature, as well as our own professional experience. This includes ongoing laboratory work to produce cultured meat and over seventy interviews with experts in the area conducted in the social science work. KEY FINDINGS AND CONCLUSIONS Cultured meat is a promising, but early stage, technology with key technical challenges including cell source, culture media, mimicking the in-vivo myogenesis environment, animal-derived and synthetic materials, and bioprocessing for commercial-scale production. Analysis of the social context has too readily been reduced to ethics and consumer acceptance, and whilst these are key issues, the importance of the political and institutional forms a cultured meat industry might take must also be recognised, and how ambiguities shape any emergent regulatory system.
