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.

Method of preventing or reducing haze in a beverage using silane-treated silica filter media

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.

Methods for forming organosilicon esters and amides are provided. Additionally, organosilicon esters and amides are provided. The organosilicon esters and amides may be formed by contacting a hydrolase enzyme with an organosilicon reactant and an organic reactant. The enzyme may catalyze the formation of an ester bond between carboxylic acid, ester, or amide functional groups of the organosilicon or organic reactant and alcohol functional groups of the organic or organosilicon reactant. The enzyme may catalyze the formation of an amide bond between carboxylic acid, ester, or amide functional groups of the organosilicon or organic reactant and amine functional groups of the organic or organosilicon reactant.

A method of treating human skin to enhance the ability of skin in the absorption and retention of moisture in order to retard skin moisture loss. There is applied to skin an organosilicon compound exhibiting humectant-like characteristics which is an anionic siliconate. An alternate method treats human skin to reduce the transepidermal water loss of skin in order to increase moisturization and to enhance skin softness. There is applied to skin an occlusive film forming organisilicon compound which is also a siliconate.
