Abstract: The present invention relates to a protein preparation of linseed and a cost-effective process for its production thereof. The protein preparation has a protein content of more than 30% by mass, an oil content of less than 68 by mass, a content of cyanogenic glycosides of less than 200 mg/kg and a brightness L* of greater than 75. The protein preparation is neutral in taste, light in color and of high quality, so that it is suitable for color and taste demanding food applications such as emulsions and baked goods.

Abstract: The present invention relates to a protein preparation produced from almond seeds and a cost-effective method for the preparation thereof. The protein preparation has a protein content of more than 50% by mass, an oil content of less than 6% by mass, a sucrose content of less than 8% by mass and a brightness L* of greater than 70. The taste of the protein preparation is neutral, it has a light colour and is of high quality, so that it is suitable for food applications, such as emulsions and baked good, that are demanding in terms of colour and taste.

Abstract: The present invention relates to a protein preparation produced from pumpkin seeds and a cost-effective method for the preparation thereof. The protein preparation has a protein content or more than 60% by mass, a fat content of less than 6% by mass and a brightness L* of greater than 70. The protein preparation has a neutral taste, is bright and of superior quality so that it is suitable for foodstuff applications with high colour demands such as drinks and yoghurts and fine bakery goods such as cakes or also for emulsions such as cremes and fillings.

Abstract: The present invention relates to a protein preparation produced from hemp seeds and to a cost-effective method for the preparation thereof. The protein preparation has a protein content or more than 65% by mass, a fat content of less than 6% by mass and a brightness L* of greater than 70. The protein preparation has a neutral taste, is bright and of superior quality so that it is suitable for foodstuff applications with high colour demands such as vegetable dairy alternatives (drinks, yoghurt, cheese) or bright vegetable alternatives to meat, poultry or fish.

Abstract: In a process for producing protein preparations from sunflower seeds a protein-containing flour made of dehulled and deoiled sunflower seeds preferably having a protein solubility in water at pH 6 of >15% by mass and/or at pH 7 of >25% by mass relative to the protein content in the flour is subjected to at least one extraction step with water at a pH of more than 4 and less than 9 to obtain a liquid phase as an extract and a solids-rich phase as a raffinate. Before and/or during the extraction step the oxygen concentration in the water is reduced to a value<7 mg/l and/or an oxidation activity is reduced by addition of antioxidant components to the water. After separation of the extract and the raffinate the extract is concentrated and/or dried to obtain a protein preparation having a high protein content. The process makes it possible to obtain qualitatively high-grade and sensorily appealing light-coloured protein preparations having a protein content greater than 75% by mass.

Abstract: The present invention relates to a biofuel and to a process for production thereof, which biofuel contains at least one fraction of triglycerides, a fraction of monoglycerides, a fraction of diglycerides and a fraction of alkylesters of fatty acids. The biofuel may be obtained by partial transesterification of vegetable oil or vegetable fat and is distinguished in that the mass fraction of alkylesters of fatty acids in the biofuel is smaller than the mass fraction of triglycerides. The fuel is suitable in particular as additive for conventional fuels, may be produced at high yield and can also be used at relatively low temperatures below 10° C.

Abstract: A method for converting biomass into higher-energy-density solids, in particular carbon, humus or peat, is described. In the method, organic substances from the biomass are suspended in water to form a suspension and at least a part of the suspension to be converted is heated to a reaction temperature and is converted into higher-energy-density solids by hydrothermal carbonization at elevated pressure. The conversion is carried out in a reaction volume which is located underneath the Earth's surface. Uniformity of the product quality and an increase in the economic efficiency of the process are achieved by the method.

Abstract: The present invention relates to a biofuel mixture comprising a fraction of fatty acid alkyl esters and at least one fraction of bound glycerol in an amount of ?1 wt %, based on the glycerol backbone, and a method and a device for producing said biofuel mixture. The biofuel mixture can be produced inexpensively, can also be utilized as a fuel in diesel engines without additional heating and can be added to conventional diesel fuel.
