Aspects of the present disclosure generally relate to systems and methods for processing biomaterials in the absence of atmospheric oxygen and products resulting from such processes. Such processing techniques may dramatically increase the shelf-life expectancies of roasted and milled biomaterial products when the roasted and milled biomaterial products are not exposed to oxygen during processing.

A system and method of manufacturing a fermented coffee formulation produces roasted and fermented coffee beans, fermented coffee juice, and a fermented coffee oil. The system includes a quantity of unprocessed coffee fruit, a quantity of primary fermentation blend, a supplemental fermentation blend, a first container, a second container, a roasting machine, and a cooling tray. The method begins by fermenting the quantity of unprocessed coffee fruit with the primary fermentation blend in the first container for coffee cherry juice. Then, a quantity of fermented coffee beans is separated from a quantity of fermented coffee fruit. In order to produce coffee beans, the quantity of fermented coffee beans is lightly roasted with the roasting machine, cooled with the cooling tray, and fermented again with the supplemental fermentation blend in the second container. A quantity of reroasted-and-refermented coffee beans is produced with the roasting machine. Fermented coffee oil is then extracted.

An efficient green method for the synthesis of noble metal/transition metal oxide nanocomposite comprising reducing noble metal salt and a templating metal oxide is disclosed. The method is a one-step method comprises mixing coffee seed husk extract, a noble metal precursor, and a transition metal precursor; and filtering and drying the nanocomposite. The nanocomposite prepared by the method of the invention displays all the characteristics and biocidal activity of a composite prepared by traditional methods.

The present invention relates to a A process for providing a fraction enriched in polyphenols from a starting material, the process comprises the steps of: (i) solubilizing the starting material in an aqueous solvent; (ii) adjusting pH to below pH 3 (preferably about pH 1); (iii) contacting the starting material with a chromatographic resin; (iv) desorbing the polyphenols from the chromatographic resin to provide an eluate comprising the polyphenols; (v) adjusting pH of the eluate to above pH 3.5 (preferably pH 4); and (vi) separating the eluate from the eluted polyphenols to obtain the fraction enriched in polyphenols. The invention furthermore related to products comprising such polyphenols enriched fractions.
