Abstract
A beverage stabilization process in which unstable beverages are contacted in a haze-free condition and at ambient temperature with positive-charge modified particulates, especially in the form of filter sheets, to initiate haze formation and the thus-formed haze is thereafter removed from the beverage at ambient temperature thereby resulting in the stabilization of the beverage.
Claims15
A process for removal of haze precursors from unstable beverages which comprises the step of contacting said beverage in a haze-free condition and at ambient temperature with a positive-charge modified porous medium comprised of fine particulate, the charge being modified with a polyamido-polyamine epichlorhydrin cationic resin, to form a precipitate and removing said precipitate from said beverage at ambient temperature.
A process of stabilizing unstable beverages against haze development which comprises conducting said beverage in a haze-free condition and at ambient temperature through a first filter medium to form haze in said beverage and thereafter filtering the formed haze at ambient temperature with a second filter medium;
- said first filter medium being comprised of fine particulate and a self-bonding matrix of cellulose fiber, the surfaces of at least one of which are modified with a polyamido-polyamine epichlorhydrin cationic resin to provide a positive Zeta potential, the matrix incorporating beaten cellulose fiber to provide a Canadian Standard Freeness of less than 600 ml.
The process of precipitating haze precursors from an alcoholic beverage which comprises contacting said beverage in a haze-free condition and at ambient temperature with a positive charge-modified porous medium comprised of fine particulate, the charge being modified with a polyamidopolyamine epichlorhydrin cationic resin.
