A method for rehabilitating coffee beans or brewed coffee, including placing a quantity of coffee solution or roasted coffee beans in a pressure-controllable environment, decreasing the pressure of the pressure-controllable environment to about 75 Torr, holding the pressure of the pressure-controllable environment at about 75 Torr for a first predetermined period of time, removing unwanted congeners, such as ethyl acetate, from the coffee solution or roasted coffee beans to yield a treated coffee, and removing treated coffee from the pressure-controllable environment.

A process for the manufacture of butanol, acetone and other renewable chemicals utilizes one or more of by-products of the manufacture of malt whisky, such as pot ale and spent lees, biomass substrates, such as paper, sludge from paper manufacture and spent grains from distillers and brewers, and diluents, such as water and spent liquid from other fermentations. The process includes treating a substrate to hydrolyze it and fermenting the treated. Also provided is a biofuel including butanol manufactured according to the process.

A process for producing a filler from brewer's spent grain. The process comprises a) comminuting the brewer's spent grain, b) heating the brewer's spent grain, c) optionally, fermenting the brewer's spent grain, d) optionally, reducing the moisture content of the brewer's spent grain, and e) optionally, mixing the brewer's spent grain with at least one flavor-modifying food additive, such as a sugar substitute(s) and/or an aroma. The brewer's spent grains may be withdrawn from a mash, such as a beer or a barley mash. The comminuting of the brewer's spent grain in step a) may be a milling. Reduction of the moisture content may be effected mechanically, in a first substep d1), and thermally, in a second substep d2). Also disclosed are a filler obtained or obtainable by this process, a use of such a filler and a foodstuff comprising at least one such filler.

Provided are methods and systems for remediating toxins present in feedstock that are used in processes to produce ethanol and other products.

The present invention concerns a method for providing a food additive from moist spent grain, comprising adjusting the pH of the spent grain to 4.5 or below by addition of a pH regulator.

The present invention consist of an aroma recovery system in an installation with a plurality of fermentation vats for preparing beverages such as white wine, red wine, beers and juices to apply a method of recovering aroma from said fermentation vats; said system comprises at least one connection system, and at least one aroma recovery equipment, wherein said connection system comprises control means such a logic controller (PLC). It is also provided a multiple connection system for connecting said plurality of fermentation vats and said aroma recovery equipment by automatic valves and a method of recovering aroma from fermentation vats of a beverage such as, for example, white wine, red wine, beer and juices.
