Abstract
A method and composition for enhancing retention of carbon dioxide in carbonated bottled beverages indicates the addition of a carbonic acid ester such as propylene carbonate, 1,3-butylene carbonate, diethyl carbonate, neopentylene carbonate and propylene carbonate or mixtures thereof. The carbonic acid ester in the aqueous medium of the beverage undergoes slow hydrolysis thereby releasing CO.sub.2 to maintain the CO.sub.2 level in the container.
Claims35
A method for maintaining carbon dioxide gas in an aqueous carbonated beverage in a container, said method comprising the step of blending an effective amount of a carbonic acid ester with said aqueous carbonated beverage for producing gaseous CO.sub.2 by hydrolysis of said carbonic acid ester, said carbonic acid ester being present in an amount sufficient to replenish CO.sub.2 loss from said container at approximately the same rate of loss from said container.
A method for maintaining carbon dioxide gas in a container made of polyethylene terephthalate homopolymers or copolymers or poly(ethylene naphthalate) or copolymers, said carbon dioxide gas being present in the container in the range of 2 to 5 vol CO.sub.2 /vol H.sub.2 O, said container having an aqueous carbonated beverage having a pH in the range of about 2 to 4, said method comprising the step of blending an effective amount of a carbonic acid ester with said aqueous carbonated beverage for producing gaseous CO.sub.2, said carbonic acid ester being present in an amount to constantly replenish CO.sub.2 loss from said container at approximately the same rate of loss from said container.
A composition for maintaining carbon dioxide gas in an aqueous carbonated beverage in a container, comprising a carbonic acid ester and said aqueous carbonated beverage, said carbonic acid ester being present in an effective amount for producing gaseous CO.sub.2 by hydrolysis of said carbonic acid ester, said carbonic acid ester being present in an amount to constantly replenish CO.sub.2 loss from said container at approximately the same rate of loss from said container.
