Embodiments of a method for removing vicinal diols from a lactic acid fermentation broth comprise the steps of contacting the lactic acid fermentation broth with functionalized silica comprising at least one hydrophobic ligand to facilitate binding of the vicinal diols to the hydrophobic ligand, and separating the contacted lactic acid fermentation broth from the functionalized silica to remove the vicinal diols.

Methods for removing vicinal diols from lactic acid fermentation broth

The present invention provides a method for preventing or reducing haze development in a beverage. Silane-treated silica filter media are synthesized. By contacting the beverage with the silane-treated silica filter, one or more haze-forming components bind to the silane-treated silica filter media and are removed by filtration. In addition, particulates in the beverage are removed by filtration. Beverages that tend to develop haze on standing and/or chilling such as alcoholic, fruit, and vegetable beverages, are suitable for the present invention. This haze in a beverage is mainly caused by polyphenols and proteins. The present invention provides a method that can reduce the levels of both polyphenols and proteins. The silica filter media useful for the present method include rice hull ash, oat hull ash, or diatomaceous earth.

The present invention provides a method for preventing or reducing off-flavor in a beverage. Silane-treated silica filter media are synthesized. By contacting the beverage with the silane-treated silica filter, one or more off-flavor substances or off-flavor precursors bind to the silane-treated silica filter media and are removed. Beverages that tend to develop off-flavor upon storage such as alcoholic, fruit, and vegetable beverages, are suitable for the present invention. The present invention provides a method that can reduce the level of off-flavor substances such as trans-2-nonenal, diacetyl, and cis-3-nonenal. The present invention also provides a method that can reduce the level of off-flavor precursors such as linoleic acid. The silica filter media useful for the present method include rice hull ash, oat hull ash, or diatomaceous earth.

The present invention provides methods for separating one or more components of interest from a sample containing particulates and soluble materials. The method comprises the steps of: (a) filtering a sample through silica filter media whose surface silanol groups have reacted with one or more silanes, and (b) simultaneously capturing particulates and binding a soluble component to the silica filter media. The bound soluble component of interest is subsequently eluted from the silica filter media. In one embodiment of the invention, unwanted soluble materials are captured by the treated silica filter media and desired component of interest is recovered from the flow-through. In another embodiment, different components of interest are recovered from both the eluate and the flow-through. Preferred treated silica filter media are silane-treated rice hull ash or diatomaceous earth with functional quarternary ammonium group or functional sulphonate group. The present invention also provides silane-treated silica filter media.

Modified silica fillers are prepared by contacting silica with blends or mixtures containing diorganodihalosilanes and tetrahalosilanes in weight ratios of 1:0.1 to 1:2, respectively. While dialkyldichlorosilanes and tetrahalosilanes such as dimethyldichlorosilane and silicon tetrachloride, respectively, are most preferred, the blends or mixtures may also comprise compositions containing other silanes such as mercaptopropyltriethoxysilane.

Tetrahalosilane blends for treating silica

Silica surfaces are contacted with compositions containing organosilicon compounds to prepare modified silica fillers. The compositions contain only organosilicon compounds which are monomeric dichlorosilanes and trialkoxysilanes. The treating compositions may be (i) mixtures or blends of dialkyldichlorosilanes, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces, or (ii) mixtures or blends of substituted dialkyldichlorosilanes in which the substituted dialkyldichlorosilanes are free of hydrocarbon or organofunctional groups reactive with silica surfaces, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces.
