  • Patent number: 11485554
    Abstract: The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.
