| Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique... |

| Difficulties with the supply of organic protein feed; low crop yields and low value of leguminous forage crops and a lack of organic fertiliszers are nowadays threesome of the major challenges faced by farms with monogastric animals. Thus, forcing the organic farmers to import feed and manure forom conventional farms. The main idea of the OrganoFinery project is to develop a green biorefinery concept where the same organic crop is utilizsed for animal feed, fertilizser and energy production in the form of methane, coping in this way with those challenges. One of the aims of the project includes the identification of crops that can be grown on organic arable farms, where there is generally a significant lack of nitrogen. Particularly legumes are... |

| Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer. In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and... |

| The extraction of leaf proteins from perennial forage crops within a green biorefinery concept represents a promising approach to face the increasing demand for protein arisen in the organic farming sector to feed monogastric animals. Given the background, the present research aims at assessing the protein extractability from three plant species i.e. chicory, red clover and timothy, at different development stages and investigating lactic acid fermentation as the key method for the extraction of leaf proteins. Based on our results, up to 86% of the proteins in the green juice were recovered in the leaf protein concentrate (LPC) by means of lactic acid fermentation. Red clover presented the highest protein content and resulted in the extraction of 65e98 kg... |

| Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant... |

| The supply of protein and essential amino acids will undoubtedly be a great challenge for European poultry nutritionists when the transition to 100% organic feed ingredients for organic poultry production becomes reality. To avoid costly and energy consuming oversea transports connected to the import of soya beans, much research effort has focussed on the exploitation of alternative locally grown protein sources to increase the sustainability of organic production systems. Besides the cultivation of protein crops like legumes (peas, lupin, and faba been) and seeds (sunflower, rapeseed), new approaches including the feeding of protein concentrates from green biomass obtained by bio-refinement are discussed. At present, many of the alternative protein... |
