While existing protein sources have been subject to various criticisms, and new concerns are emerging including the growth in antibiotic resistance associated with intensive animal production, they will have to continue to be significant sources of supply. Bioactivities associated with cereal proteins include antioxidant, anti-inflammatory, cholesterol-lowering, satiety, anti-diabetic and others as reviewed recently [18]. Food consumption trends and driver. These compounds that cause umami taste in seaweeds are present due to the environment in which seaweeds grow which are often hostile. A big issue with the development of in vitro meat products is the complexity of factors which contribute to the final eating quality of real meat. They have two full-scale production lines in the US, with another in Brazil (capacity of 100,000 mt/year) [35]. Technology advancements include advances in data-enabled technologies as well as improvements in production and processing technologies. While cell culture technology may be able to work towards providing the range of necessary micro and macro molecules which are reflective of raw muscle, mimicking the influence of environmental factors will remain very challenging. Red meat, on the other hand, was classified as probably carcinogenic to humans (every 100 g of red meat consumption leads to a 17% increased risk). Verg X.P.C., Maxime D., Dyer J.A., Desjardins R.L., Arcand Y., Vanderzaag A. Therefore, industrial CO 2 could be collected and used for cultivation of microalgae as part of Borello M., Caracciolo F., Lombardi A., Pascucci S., Cembalo L. Consumer perspective on circular economy strategy for reducing waste. In relation to cardiovascular disease (CVD), however, research seems more inconsistent and there is debate regarding the paucity of data from randomized controlled trials (RCT). Given that they are most likely to be accepted as ingredients rather than whole, such a chain includes ensuring a safe and reliable feedstock for the insect, mass rearing of insect larvae, their processing into insect ingredients, and application of these ingredients in final food products. Edible insects in a food safety and nutritional perspective: A critical review. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. While it is possible to adequately meet the nutritional requirements of a larger global population based on current supply volumes, it is highly likely the balance of driving and opposing forces, and a reluctance of policy makers to impose austere diets on citizens, will result in a world which will demand significantly more protein in the future. These in turn are influenced by the environment in the abattoir such as chilling regime, hanging method and electrical inputs. This involves feeding shrimp excrement to microorganisms which in turn are consumed by the shrimp as a source of protein. Sustainable Aviation Fuel Grand Challenge. Dairy production at farm level is subject to many of the negative environmental impacts associated with meat production due to its requirement for land and water and production of GHGs. Van Kernebeek M.R.J., Oosting S.J., Van Ittersum M.K., Bikker P., De Boer I.J.M. 1Department Agri-Food Business and Spatial Analysis, Rural Economy and Development Programme, Teagasc Food Research Centre, Ashtown, Dublin D15 KN3K, Ireland, 2Food BioSciences Department, Teagasc Food Research Centre, Ashtown, Dublin D15 KN3K, Ireland; ei.csagaet@seyaH.airaM, 3Food Quality and Sensory Science, Teagasc Food Research Centre, Ashtown, Dublin D15 KN3K, Ireland; ei.csagaet@nelluM.ennA, 4Teagasc Food Research Programme, Teagasc Food Research Centres, Ashtown and Moorepark, Fermoy, Co.

Challenges and prospects for consumer acceptance of cultured meat. In particular, there is a case to be made for the promotion of meat produced from grass-fed ruminants [44]. Cereal proteins account for the major portion of dietary protein intake globally [13,14] and are important for animals as well as humans. Furthermore, due to the high cost and limited availability of animal proteins in several countries and consumer concerns over health benefits of animal-based proteins, increased attention has focused on the utilization of plant-based proteins as potential sources of low-cost dietary proteins for food use [58]. Forum for the Future The Future of Protein: The Protein Challenge 2040. Hernndez-Ledesma B., Del Mar Contreras M., Recio I. Antihypertensive peptides: Production, bioavailability and incorporation into foods. Being cold-blooded, they perform better in terms of feed conversion efficiency, and they reproduce more rapidly [76]. Kunjapur Aditya M. Photobioreactor Design for Commercial Biofuel Production from Microalgae. Mark Fenelon wrote Section 3.3. 8. Safety of novel protein sources (insects, microalgae, seaweed, duckweed and rapeseed) and legislative aspects for application in food and feed production. The infant formula sector has particularly stringent quality specifications, including microbial specifications and chemical residues (e.g., veterinary drug residues). Such food-derived bioactive peptides have gained increased interest as agents in the control of chronic diseases [22,23,24] and to reduce the risk of side effects arising from synthetic drugs usage. The possibility of producing meat without slaughtering animals carries an obvious benefit, as does the availability of a meat product with a much-reduced environmental impact. Evolution in protein consumption per capita (g/capita/day). [(accessed on 2 March 2017)]; The State of Food Insecurity in the World, Addressing Food Insecurity in Protracted Crises. Notwithstanding the argument to maintain existing protein sources in the diet, it is clear that the way we produce and consume protein has significant impacts on the environment and on human and animal health which necessitate action. Seaweed ash salt was used in the past in regions where salt was not plentiful in countries such as Denmark and Brittany. Brijesh Tiwari wrote Section 4.1. A range of microalgae species are produced in hatcheries and are used in a variety of ways for commercial purposes, including for human nutrition, as biofuel, in the aquaculture of other organisms, in the manufacture of pharmaceuticals and cosmetics, and as biofertiliser. The U.S. Department of Energy is working with the U.S. Department of Transportation, the U.S. Department of Agriculture, and other federal government agencies to develop a comprehensive strategy for scaling up new technologies to produce sustainable aviation fuel (SAF) on a commercial scale. While the drive towards diversified protein sources could be considered a threat by companies in meat and dairy sectors, for example, there are also significant opportunities for such companies to create new, high value by-products from undervalued waste streams as well as becoming directly involved in the development of new products from diversified protein sources. On cherche comprendre (avec la photobiologie) valoriser la production d'hydrogne par des micro-algues. While meat consumption carries clear health benefits, over-consumption can lead to negative health impacts. However, fish protein is also a rich source of bioactive peptides. A growing global population, combined with factors such as changing socio-demographics, will place increased pressure on the worlds resources to provide not only more but also different types of food. Les microalgues procaryotes. Even biofuel. Quality characteristics, chemical composition, and sensory properties of butter from cows on pasture versus indoor feeding systems. Greater alignment of political forces, and the involvement of wider stakeholders in a governance role, as well as development/commercialization role, is required to address both sources of protein and ensure food security. Nonetheless, food products are available on the market including cricket protein bars produced by British company Next Step Foods, and are on the shelves in European supermarkets including the Belgian supermarkets Delhaize and Carrefour. The amino acids aspartic and glutamic acids constitute a large proportion of the amino acids of brown seaweeds (2244% of total amino acids in some brown algal species). Hayes M. Bioactive peptides and their potential use for the prevention of diseases associated with Alzheimers disease and mental health disorders: Food for Thought? They, especially the red and green varieties, are very rich in protein (up to 47% dry weight in the red seaweed Porphrya sp. En les cultivant When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.It is also carbon negative unless the dead plant matter is The WRAP report states that ensuring the UK has a diversified, sustainable and healthy supply of protein will be one of the defining challenges of the coming decades. Nonetheless, current primary production systems remain expensive, with a need to develop automation processes to make insect production economically competitive; extraction processing systems are also too costly and need further development [72]. Addressing this perfect storm will necessitate more sustainable production of existing sources of protein as well as alternative sources for direct human consumption. Klose C., Schehl B.D., Arendt E.K. Federal government websites often end in .gov or .mil. wood logs), some people use the words biomass and biofuel interchangeably. Proponents of entomophagy argue that it has a lower environmental impact compared to meat production [74]. Kearney J. Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Shaping the Future of Food. Novel proteins require the development of new value chains, and attention to issues such as production costs, food safety, scalability and consumer acceptance. Furthermore, positive environmental impacts cannot be assumed with novel protein sources and care must be taken to ensure that comparisons between novel and existing protein sources are valid. Bioactivities associated with oat, barley and wheat protein derived peptides include opioid activity while rice protein contains the sequence RGD and lack celiac toxicity which could be beneficial in health and nutrition. Van Huis and colleagues [72] relate the absence of a history of consuming insects to the difficulty of harvesting a proper meal of insects in temperate zones (insects tend to be less abundant, smaller and found less often in clumps in temperate zones). [(accessed on 14 July 2017)]; Becker E.W. All authors read and approved the final version of the paper. Both can be produced from biomass (as "biobutanol") as well as from fossil New models of production are also emerging, e.g., soil-less growing and indoor farming. Similarly, on-farm factors, in particular diet, can influence the flavour. Torino, Italia: Ed. Crickets, lesser mealworm and yellow mealworm are potential insects for application for food in the EU while black soldier fly, yellow mealworm and the common housefly have potential for use in feed products [13]. Furthermore, many insects are consumed whole, which includes their gut microflora which may affect microbiological quality of the food product [10] and specific health implications associated with using organic feedstocks to produce the insects need to be assessed (for example (undesirable) substrate materials can be transferred into the protein products and thus into the human food chain). Illgner P., Nel E. The Geography of Edible Insects in Sub-Saharan Africa: A study of the Mopane Caterpillar. Maria Hayes wrote Section 3.1, Section 4.3 and Section 5.1. Udenigwe C.C., Aluko R.E. In this increased efficiency strategic perspective, the livestock sector (and its sectoral organizations) is identified as an important stakeholder in delivering on the mitigation efforts necessary to reduce GHG emissions and to improve its environmental footprint [37] with public policy to support on-farm investment and reduce risk associated with the adoption of new technologies, and extension efforts that disseminate best practice and highlight success stories, being important approaches. Gangopadhyay N., Wynne K., OConnor P., Gallagher E., Brunton N.P., Rai D.K., Hayes M. In silico and in vitro analysis of the angiotensin-I-converting enzyme inhibitory activity of hydrolysates generated from crude barley (. However, the word biofuel is usually reserved for liquid or gaseous fuels used Studies carried out previously suggest that the method of extraction has an impact on digestibility of protein but that seaweed derived proteins are for the most part digestible and comparable to casein but the carbohydrate fraction and phlorotannins found in brown seaweeds can affect digestibility [83]. Analysis of such data by Henchion et al. There is strong scientific evidence for this. In many places, fish and shellfish are the only readily available sources of protein that people can self-harvest, often throughout the year. Klunder H.C., Wolkers-Rooijackers J.C.M., Korpela J.M., Nout M.J.R. Microalgae reach about three to eight percent efficiency in transforming solar energy to chemical energy, while conventional biofuel crops stay below 1 percent. Coker R.H., Miller S., Schutzler S., Deutz N., Wolfe R.R. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. Advances in production technologies, including technologies such as advanced monitoring systems (e.g., biomass monitoring and harvest monitoring) and remote sensing, and biological innovations in genomics and plant breeding will improve input efficiencies and help to anticipate and thus mitigate production risks (e.g., weather and pest related risks). De Smet S., Voosen E. Meat: The balance between nutrition and health. Rising consumption of meat and milk in developing countries has created a new food revolution. 1 The data used measure availability as opposed to demand, i.e., demand is calculated as a residual based on total available for human consumption = total food supply feed seed industrial uses waste. Butanol may be used as a fuel in an internal combustion engine.It is more similar to gasoline than it is to ethanol.A C4-hydrocarbon, butanol is a drop-in fuel and thus works in vehicles designed for use with gasoline without modification. Wu G.Y., Fanzo J., Miller D.D., Pingali P., Post M.J., Steiner J.L., Thalacker-Mercer A.E. Maeve Henchion initiated the paper, developed the framework and wrote Section 1, Section 2, Section 4.2 and Section 5. Products obtained by using a blend of cereal and pulses can balance the amino acids and may improve the nutritive value of the product. Proteins in pulses are found in the cotyledon and the embryonic axis of the seed with small amounts present in the seed coat. At the processing level, there is recognition of a growing need to adopt sustainable manufacturing processes, including energy and water/wastewater conservation; this is currently contributing to the re-engineering of unit operations within dairy manufacturing plants [53]. Maize (corn) is important for global food security. From an environmental perspective, dairy production/processing systems have been reviewed and the carbon footprint determined [54,55]. During production of dairy-based ingredients, as the protein content is increased, lactose and mineral salts are removed generating a by-product permeate stream, i.e., ultrafiltration of skim milk generates MPC and milk permeate whereas filtration of whey generates WPC and a whey permeate. In addition, maize as a source of protein is very similar in terms of its contribution to calories intake globally. Sampels S. Towards a more sustainable production of fish as an important source for human nutrition. The protein content of seaweeds differs according to species. From an environmental perspective, meat production, at a global level, contributes significantly to climate change and land use change [40]. Whey protein and essential amino acids promote the reduction of adipose tissue and increased muscle protein synthesis during caloric restriction-induced weight loss in elderly, obese individuals. The amino acid content of seaweeds is comparable to protein sources such as eggs or soybean. Such factors include increased awareness of the impact of food production and consumption on the environment and on health. Consumption of Red Meat and Processed Meat. Algae produce H 2 gas under anaerobic conditions by providing hydrogenases with hydrogen ions derived from splitting of water molecules via photosynthesis. Source: Wikimedia Commons. Tresina P.S., Mohan V.R. Previous and predicted global petroleum sources (A) Global liquid fuel use in 2006 was predominantly (96.3%) conventional petroleum, with slightly less than 1% being biofuels. In addition to economic and sensory factors, environmental, ethical and societal factors are at play. Van Zanten H.H.E., Mollenhorst H., Klootwijk C.W., van Middelaar C.E., de Boer I.J.M. In tandem to meat production, animals also produce a variety of other goods and services. Some organizations and commercial companies are setting up production on an industrial scale, e.g., the FAO established an insect farming project in the Philippines in 2010 [80], Swiss company Bhler is setting up pilot facility in China to process fly larvae and mealworms, and there are a few industrial scale enterprises in various stages of start-up within Europe for raising insects such as black soldier flies. As a source of food (as opposed to feed), it accounts for 25% and 15% of total maize consumption in developing countries and globally, respectively. In addition, red seaweeds including Porphyra sp, (common name Nori) also impart umami taste due to nucleic acids present within their cells.
