摘要:
A process is described for preparing a plant protein preparation for a foodstuff. In the process, a proteinaceous vegetable raw material is introduced into a salty, aqueous extractant for the extraction of proteins, whereby a salty plant protein solution is obtained. The proteins are precipitated by lowering the temperature and/or the ionic strength of the plant protein solution and separated from the aqueous extractant as a moist protein-rich substance. The process is distinguished by the fact that the plant protein solution, before or after the protein precipitation step, or the protein-rich substance, before or after introduction into the foodstuff and before finishing the foodstuff, is heated to a temperature of ≧45° C. and held at this temperature for a period of time, the period of time and the temperature being chosen so that the use properties and processing properties of the protein-rich substance are not altered by this step. Due to this pre-heating operation, the plant protein preparation causes a lower degree of undesired off-flavors upon heating of the foodstuff in which it has been processed. Also described is a method for producing a plant protein preparation in the form of a moist protein mass for improving the texture of foodstuffs with improved organoleptic properties.
摘要:
The invention relates to a protein preparation and a method for the production thereof. The protein preparation includes protein particles. A protein particle includes several plant protein molecules with at least one hydrophilic and at least one hydrophobic moiety each. The protein molecules are bound to each other in such a manner that the protein particle has a mainly hydrophobic surface. The preparation allows production of foodstuffs that are rich in protein, that have a pleasant taste, that do not appear to be dry, solid, hard or crumbly, that do not cause increased saliva production and that are easy to swallow.

The invention relates to a method for eliminating unwanted accompanying substances, particularly fragrance, flavor, and colour components, from vegetable proteins. Said method encompasses the following steps: (i) a vegetable raw material is extracted using an extracting agent such that, a vegetable protein extract is obtained; (ii) an inorganic adsorber material is added to the vegetable protein extract, a process in which unwanted accompanying substances, especially fragrance, flavor, and/or colour components, are bonded to the inorganic adsorber material.
摘要:
A method for obtaining a vegetable protein fraction, in particular for producing vegetable ice cream, is described wherein vegetable parts are added to water or to an aqueous solvent in order to dissolve and/or disperse vegetable proteins from the vegetable parts, and wherein one or more vegetable protein fractions are separated from the aqueous mixture thus obtained by the separation. According to the method, one or more substances having lipophilic or amphiphilic boundary surfaces are added to the aqueous mixture in order to separate one or more vegetable protein fractions, to which dissolved and/or dispersed proteins having lipophilic or amphiphilic groups in the mixture attach. The substances including the attached proteins are separated from the mixture. A vegetable protein fraction having particularly good emulsifying characteristics is obtained by the method, the protein fraction being advantageous as an emulsifier in the production of vegetable ice cream.

The present invention relates to a method of obtaining protein preparations from sunflower seeds as well as protein preparations produced with the method. In the method the sunflower seeds are dehulled to a residual hull content of 5% by weight or dehulled sunflower seeds with a residual hull content of 5% by weight are provided. Mechanical partial deoiling of the dehulled sunflower seeds is carried out through pressing up to a fat or oil content of the dehulled sunflower seeds in the range 10 to 35% by weight. After carrying out one or more extraction steps with at least one solvent, a defatted flour containing protein is obtained as a protein preparation. Both optically and functionally the protein preparation has very advantageous properties which allow it to be used directly in the food product or animal feed sector.

摘要:
The present invention relates to a method for producing a protein-containing food ingredient, in which flax coarse meal having a low residual oil content is produced or provided, from which parts of native flax protein and soluble roughage are dissolved or at least dispersed by aqueous extraction in an aqueous phase. The aqueous total extract thus obtained is freed of insoluble flax coarse meal fractions. Subsequently, a flax protein/roughage mixture is partitioned from the aqueous phase, in order to thus obtain the food ingredient. The food ingredient obtained in this way is taste-neutral, is technologically functional and storage-stable, and is distinguished by good protein solubility and outstanding boundary-surface properties.
