The efficient use of natural resources is essential for the planet’s sustainability and ensuring food security. Colombia’s large availability of water resources in combination with its climatic characteristics allows for the development of many microalgae species. The use of microalgae can potentially contribute to sustainable production in support of the agri-food sector. The nutritional composition (proteins, carbohydrates, fatty acids, vitamins, pigments, and antioxidants) of microalgae along with the ease of producing high biomass yields make them an excellent choice for human and animal nutrition and agriculture. Several species of microalgae have been studied seeking to develop food supplements for pigs, ruminants, poultry, fish, crustaceans, rabbits, and even bees. Important benefits to animal health, production, and improved bromatological and organoleptic characteristics of milk, meat, and eggs have been observed. Based on the functional properties of some microalgae species, foods and supplements have also been developed for human nutrition. Moreover, because microalgae contain essential nutrients, they can be utilized as biofertilizers by replacing chemical fertilizers, which are detrimental to the environment. In view of the above, the study of microalgae is a promising research area for the development of biotechnology and bioeconomy in Colombia.

AbstractGlobal food security, livestock production and animal health are inextricably bound. However, our focus on the future tends to disaggregate food and health into largely separate domains. Indeed, much foresight work is either food systems or health-based with little overlap in terms of predictions or narratives. Work on animal health is no exception. Part of the problem is the fundamental misunderstanding of the role, nature and impact of the modern futures tool kit. Here, I outline three key issues in futures research ranging from methodological confusion over the application of scenarios to the failure to effectively integrate multiple methodologies to the gap between the need for more evidence and power and control over futures processes. At its core, however, a better understanding of the narrative and worldview framing much of the futures work in animal health is required to enhance the value and impact of such exercises.

Urban gardening finds itself at a juncture – not only are crises caused and exacerbated by the industrial food system urgently demonstrating the need for more localised, sustainable, and democratically-determined food systems, but alternative food movements are increasingly negotiating crises of their own. Critical Foodscapes was a one-day conference part-funded by Warwick’s Institute of Advanced Study (IAS) and the Food GRP. The conference was put together with the intention of bringing a ‘critical studies’ approach to the emerging research area of urban community food growing; namely, to put critical – but constructive – pressure on some of the assumptions which underlie current theory and practice of the various forms of urban food growing. This article offers some reflections on the conference itself as well as on the prospects for urban gardening more generally.

<p>The obstacle in developing coconut water-based product is its easily altered properties. Ultrafiltration and ultraviolet processing are potential to obtain a longer shelf life for coconut water drink without altering its nutritional values and unique organoleptic properties, unlike other processing techniques e.g. pasteurization and ultra high temperature. Shelf-life estimation experiment showed that ultrafiltration-and- ultraviolet-processed coconut water without any addition of food additives can be stored for 51 days in 00C. The objective of this research was to evaluate the effects of ultrafiltration and ultraviolet treatments on the nutritional, physicochemical and organoleptic properties of coconut water drink. The experiments were carried out at Food Analysis Laboratory, Indonesian Center of Agricultural Postharvest Research and Development, on January-April 2015. Coconut water was flown through the ultrafiltration membrane unit and ultraviolet light unit, samples were collected in three repetitions. Nutritional composition and physicochemical properties of fresh coconut water (FCW) and coconut water drink obtained from ultrafiltration and ultraviolet process (CUU) were evaluated and compared. Organoleptic analysis was done by 20 panelists, observations included quality hedonic (aroma, sweetness, saltiness, sourness and turbidity), and acceptance (preferance and ranking test), comparing FCW and CUU with commercial coconut water drink (CWD). CUU showed indistinguishable nutritional composition and physicochemical characteristics from FCW (p&gt;0,05), except on total sugar (p=0,049), clarity (p=0,001), L* (lightness) (p=0,000) and b* (yellowish) (p=0,002). Panelists gave CUU a statistically equal rank to FCW, and better than CWD. The organoleptic characteristics of CUU were concluded as relatively same in saltiness and aroma as FCW, and less intense in sweetness and turbidity compared to CWD. After 10 days storage, panelists level of liking was higher for CUU compared to CWD in color (p=0,004) and general appearance (p=0,016).</p><p>Keywords: coconut water, nutritional composition, organoleptic properties ultrafiltration, ultraviolet</p>

AbstractThere is consensus that the global food system is not delivering good nutrition for all and is causing environmental degradation and loss of biodiversity, such that a profound transformation is needed to meet the challenges of persistent malnutrition and rural poverty, aggravated by the growing consequences of climate change. Agroecological approaches have gained prominence in scientific, agricultural and political discourse in recent years, suggesting pathways to transform agricultural and food systems that address these issues. Here we present an extensive literature review of concepts, definitions and principles of agroecology, and their historical evolution, considering the three manifestations of agroecology as a science, a set of practices and a social movement; and relate them to the recent dialogue establishing a set of ten iconic elements of agroecology that have emerged from a global multi-stakeholder consultation and synthesis process. Based on this, a consolidated list of principles is developed and discussed in the context of presenting transition pathways to more sustainable food systems. The major outcomes of this paper are as follows. (1) Definition of 13 consolidated agroecological principles: recycling; input reduction; soil health; animal health; biodiversity; synergy; economic diversification; co-creation of knowledge; social values and diets; fairness; connectivity; land and natural resource governance; participation. (2) Confirmation that these principles are well aligned and complementary to the 10 elements of agroecology developed by FAO but articulate requirements of soil and animal health more explicitly and distinguish between biodiversity and economic diversification. (3) Clarification that application of these generic principles can generate diverse pathways for incremental and transformational change towards more sustainable farming and food systems. (4) Identification of four key entry points associated with the elements: diversity; circular and solidarity economy; co-creation and sharing of knowledge; and, responsible governance to enable plausible pathways of transformative change towards sustainable agriculture and food systems.

Organic Livestock Production

Due to the increasing interest in organic farming, an overview of this research area is provided through a bibliometric analysis conducted between April and May 2019. A total of 320 documents were published up until 2018 on organic livestock farming, with an annual growth rate of 9.33% and a clear increase since 2005; 268 documents have been published in 111 journals. Germany is the country with the largest number of published papers (56 documents). Authors’ top keywords (excluding keywords used for running the search) included: animal welfare (29 times), animal health (22 times), cattle (15 times), grazing (10 times), and sheep (10 times). This could indicate that more research has been done on cattle because of the importance of this species in Germany. Moreover, the prevalence of the terms ‘animal welfare’ and ‘animal health’ may indicate that the research on organic livestock production has been focused on these two areas. The bibliometric analysis indicates that: (i) countries focused the organic livestock production research on their main production, and (ii) more research in species other than cattle and sheep is needed.

Abstract Concerns regarding the effects of red meat on human and environmental health are prompting consumer interest in plant-based diets. As global food systems strive to meet the dietary needs of an estimated mid-century population of 10 billion, a new generation of plant-based meat alternatives—formulated to mimic the taste and nutritional composition of red meat—have attracted considerable consumer interest, research attention, and media coverage. We used untargeted metabolomics to provide an in-depth comparison of the nutrient profiles of grass-fed ground beef and a market-leading plant-based meat alternative. Metabolomics revealed a 90% difference in nutritional profiles beef and a popular plant-based meat, many of which can have important consumer health implications. This information could not be determined from their Nutrition Facts, which suggests nutritional similarity. Our findings indicate that beef and a popular plant-based meat should not be viewed as nutritionally interchangeable, but as complementary in terms of provided nutritional entities. As society aims to increase food production with ~ 60% by 2050, the meat and the plant-based meat industries will likely coexist and have to complement each other in order this reach this goal.

Winter School

Why have we organized winter school? We believe everyone should be able to understand how important is Food Environment and Health Risk Assessment in Danube Region. The environment plays a crucial role in people’s physical, mental and social well-being. The degradation of the environment, through air pollution, noise, chemicals, poor quality water and loss of natural areas, combined with lifestyle changes, may be contributing to substantial increases of civilisation diseases. The production and consumption of sufficient, affordable and nutritious food, while conserving the natural resources and ecosystems on which food systems depend, is vital. Food systems play a central role in all societies and are fundamental to ensuring sustainable development. Sustainable food systems are critical to resolving issues of food security, poverty alleviation and adequate nutrition, and they play an important role in building resilience in communities responding to a rapidly changing global environment. 13 students from around the world joined our 2- week Winter School Programme in Slovak republic, Slovak University of Agriculture in Nitra, Faculty of Biotechnology and Food Sciences. CASEE Online Winter School was multidisciplinary, encompassing chemistry, environment, microbiology, nutrition, quality assurance, sensory analysis, management, food engineering and manufacturing and also about very actual problematic Covid-19 and its impact on agri-food sector. The Winter School gave our participants an idea of how interesting these topics really are. Online lectures were provided by experts in agri-food sector from Slovak University of Agriculture in Nitra, professional lecturers from prestige universities all over the world, state authorities, research institutes and SMEs as well as representatives from CASEE universities.

There is an increasing interest in the use of insects in animal feed since they contain high proteins levels, lipids, vitamins and minerals. In particular, insect-derived proteins are seen as one of the potential solution to face the increasing protein shortage and are able to fully substitute soybean meal or fishmeal in aquaculture or livestock feeds. However, beside their interesting nutritional composition, insects are also rich in bioactive compounds such as chitin, antimicrobial peptides or specific fatty acids with immunostimulating, antimicrobial and/or anti-inflammatory properties able to sustain animal health, increase their resistance to diseases. Further studies will also have to investigate whether insects share similarities with bacterial or parasitical pathogens and may act as immunostimulants. These recent findings may launch insects beyond the protein concept into healthy animal feeds. This review presents the effects of insects and their bioactive compounds on fish and crustaceans, poultry, pigs and rabbits immune system, gut health, microbiota and resistance to diseases.
