  • Publication number: 20230413856
    Abstract: Methods for producing a meat substitute with plant-based fat contents are disclosed. The methods include the use of protein and/or polysaccharide polymer with fibrillar properties in combination with protein sources of essential amino acids such as plant-based protein. These polymers may be mixed together and then combined with an oil phase emulsion to produce a precursor emulsion. The precursor emulsion may then be processed into three-dimensional fiber structures that include muscle-like fibers with fat encapsulation of the proteins. A contemplated method for forming the fibers includes centrifugally spinning the precursor emulsion to form the fibers.
