The present technology provides a method for preparing an acid-reducing filter that includes depositing a mineral blend layer to a filter substrate, where the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1, the mineral blend is free of soluble halide or hydroxide salts of alkali or alkaline earth metals, and the mineral blend layer is insoluble in water.

The present invention relates to a liquid coffee beverage comprising liquid coffee infused with nitrogen thus producing a refreshing cold foamy and creamy beverage.

A system and method for reducing the amount of caffeine in an existing volume of brewed coffee. The brewed coffee contains a predetermined level of caffeine. To reduce the caffeine, a caffeine filter is provided. Furthermore, a coffee receptacle is provided to hold the decaffeinated coffee. A filter chamber is positioned over the coffee receptacle. The caffeine filter is placed in the filter chamber. Brewed coffee is dripped, poured, or otherwise advanced into the filter chamber. At least some of the brewed coffee flows through the caffeine filter and into the coffee receptacle. This reduces the level of caffeine of the filtered coffee entering the coffee receptacle. The system also enables a single source of brewed coffee to produce cups of both regular coffee and decaffeinated coffee, using only one type of regular ground coffee.

A method for cold-brewing a non-acidic coffee product may include adding minerals to water, creating mineralized water; brewing an alkaline coffee product using the mineralized water; and removing coffee grounds from the alkaline coffee product. The brewing step may be a cold-brewing step including soaking coffee in the mineralized water for a desired period of time, such as from about 8 to about 24 hours. The minerals may be carbonate compounds or any other compound capable of raising the pH level of the water to be greater than 7 prior to brewing. The resulting product may be a non-acidic coffee product.

The invention relates to a caffeine-templated MIP copolymer matrix and devices employing these polymers that exhibit high absorbance or binding capacity for caffeine while retaining rapid caffeine uptake kinetics, and which function in both cold and hot aqueous environments to selectively remove caffeine from a beverage with a high selectivity factor in order to better preserve the sensory aspects of the decaffeinated beverage, and which can easily be used by a typical consumer to treat their beverage within a short time frame of less than about one minute. More specifically, the invention relates to copolymeric MIP matrices produced according to methods wherein the template to polymer ratio is dramatically increased in order to raise the affinity of the resulting MIP materials, and hyper-crosslinked MIP matrices produced using higher amounts of crosslinking agents to produce high affinity copolymer matrices that better maintain a high degree of selectivity towards caffeine while minimizing the uptake of congeners to better maintain the sensory characteristics of the decaffeinated beverages. The invention further relates to manual and mechanical devices employing the inventive MIP matrices in a variety of physical forms and configurations that enable a user to decaffeinate a beverage manually or automatically within one minute or less, or select a level of decaffeination by controlling the exposure time to said devices.

The present invention relates to coffee beverage compositions comprising soluble coffee solids and particles of roast coffee beans and with reduced formation of scum and a low content diterpenes. The invention further relates to methods of producing such coffee beverage compositions by removal of oil from a slurry of particles of roast coffee beans.

The present invention relates to the methods for extraction of natural caffeine from caffeine containing biological material.
