  • Patent number: 4277513
    Abstract: A process for the manufacturing of a meat-analog foodstuff using an aqueous protein paste as the starting material. In this process, the aqueous paste which is prepared by grinding meat, poultry or fish offals is cooled until it partly solidifies as a plastic mass whereafter it is subjected to mechanical forces which cause the protein fibrils of the mass to reorient themselves in a preferred direction thus imparting to the mass a texture resembling that of muscular fibers.
    Type: Grant
    Filed: December 5, 1979
    Date of Patent: July 7, 1981
    Assignee: Battelle Memorial Institute
    Inventors: Willy Rufer, Robert Menzi
  • Patent number: 4039694
    Abstract: A protein food product having a general appearance, taste, nutritional properties similar to those of dried meat and having also a cracked texture similar to the fibrous texture of dried meat is produced by partially dehydrating a homogeneous mass of aqueous vegetable protein gel.
    Type: Grant

  • Patent number: 3998976
    Abstract: A low-calorie confection, having a combination of at least one layer of marshmallow and at least one layer of a homogeneous paste containing 20 to 30 per cent by weight of purified edible alpha cellulose powder, 3 to 5 per cent by weight of proteins, 3 to 10 per cent by weight of lipids, 45 to 60 per cent by weight of sugars and 10 to 15 per cent by weight of water, the calorific value of this paste being at most 300 calories per 100 grams.
    Type: Grant

  • Patent number: 3973044
    Abstract: The present invention is a proteinaceous food product and a method of its production. A mixture of protein and water is formed into a thin film between successive parallel rolls rotating in opposite directions and at sequentially increasing speeds so as to impart at least a 40% stretch to the film prior to removing the stretched film from the last roll with a blade set at an angle to the roll. The scraping off of the thin film forms a structure consisting of groups of many small folds interspersed on substantially larger folds. Compaction of this material creates a fiberous structure composed of the numerous small folds of material surrounded by a matrix of the material once comprising the larger folds. This compacted structure approximates the structure of natural meat where fibers are dispersed in a matrix of connective tissue.
