A tribo-electro static separation process and system for the preparation of various food and feed products. A tribo-electric separation process and system for fractionating a feed mixture comprising at least two members of the group of proteins, starches, soluble and insoluble fibers. Namely, supplying a feed mixture comprising at least two of the group of proteins, starches, soluble and insoluble fibers to a tribo-electric separator and simultaneously charging and separating the feed mixture into at least two subfractions, with one of the subfractions enriched in one of protein, starch and fiber and having a composition different than the feed mixture.

This application provides a high quality protein composition and the processes of making the same. The compositions prepared by filtration according to the instant application may contain higher percentage of branched chain amino acids (BCAA) and/or essential amino acids (EAA). The compositions may have reduced level of sodium and also lighter color than that of the composition before passing through the filtration means.

This invention provides a high quality soluble protein composition and the processes of making the same. According to the described methods, a non-pumpable broth may be converted into a pumpable broth by using a filtration means. The resulting compositions are shelf-stable, easy to use and have excellent nutritional values as compared to other protein products.

A process for obtaining fish gelatin characterized because it comprises: (a) cleaning of fish skins; (b) washing of skins with water; (c) treating with diluted alkali solution with constant agitation; (d) washing of skins with water until the wash water is in a pH range between 6.8 and 7.2; (e) treating with diluted organic acid solution with constant agitation; (f) washing of skins with water until the wash water is in a pH range between 6.8 and 7.2 and subsequent runoff; (g) extracting gelatin by mixing the skins in an organic acid solution with a concentration of 0.2 to 0.3 weight percent by volume at a temperature of 55 to 65 C. and for 260 to 340 minutes; (h) filtering to remove skin debris and impurities; (i) drying; and (j) grinding.
