Abstract: The present invention provides an improved process for increasing the chill haze stability of aqueous liquids derived from fruits and vegetables, (e.g., beer, wine, fruit juices, vinegar, etc.) by using one or more haze control agents in a precoat or after precoat layer in the filter media used to filter the liquid and by adding one or more haze control agents as a body feed upstream of the filter. In a preferred embodiment one or more haze control agents are also added in ruh storage at a time in the process significantly before the filtration step. This improved process permits the beverage to be packaged immediately after filtration, thus eliminating the time consuming and space consuming storage following filtration normally required by conventional chill haze control techniques.

Abstract: Undesirable protein and polyphenol molecules are removed from aqueous liquids or suspensions, such as wort, wine, or beer, by contacting the liquid with acid-treated synthetic magnesium silicates containing less than about 14% magnesium oxide. The resultant liquid is more resistant to chill haze formation. Even better results are obtained if a polyamide is blended with the acid-treated synthetic silicate prior to contact with the liquid. A filter aid, such as diatomite, can also be combined with the acid-treated synthetic magnesium silicate and/or the blends containing the polyamide.
