A method for predicting late fermentation production of diacetyl in a brewing process comprises determining the ratio of FAN (free amino nitrogen content) to sugar (fermentable) to specific gravity in an initial wort composition. In addition there is provided a process for preventing incipient late fermentation production of diacetyl in a brewing process, comprising measuring and variously adjusting the initial FAN, sugar and specific gravity of the wort such that the ratio for the adjusted wort has a value of 37 or less.

A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.

Liquid-solids circulating fluidized bed

A method and apparatus for bioprocessing particles wherein particles are entrapped a porous material and have biologically active microorganisms on their surfaces. A liquid (carrying oxygen and/or nutrients for said microorganisms) is passed through the entrapped particles and microorganisms and microorganisms are active to breakdown said particles. After a suitable period of time the particles are removed from the matrix.
