摘要

"PROCESSES FOR MAINTENANCE OF CARBON DIOXIDE GAS IN A CARBONATED WATER DRINK IN A CONTAINER AND FOR MAINTAINING CARBON DIOXIDE GAS IN A CONTAINER MADE OF HYPOLYLOMERS OR COPOLYMERS OF POLYLEYLATE OIL, POLYLEYLATE OIL (POLYLEYLATE OIL). , COMPOSITION TO MAINTAIN CARBON DIOXIDE GAS IN A WATER CARBONATED DRINK IN A CONTAINER "The present invention relates to a process and composition for enhancing carbon dioxide retention in carbonated bottled drinks by the addition of a carbonic acid ester such 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 drink thus undergoes slow hydrolysis thereby releasing CO ~ 2 ~ to maintain the level of CO ~ 2 ~ in the container.
