A method of preserving a food by contacting the food with a noble gas, a mixture of noble gases or a mixture containing at least one noble gas.

Method of preserving foods using noble gases

A method of improving the aroma and flavor of coffee, which entails contacting the same with a noble gas, mixture of noble gases or mixture containing at least one noble gas during at least a portion of any stage of processing or storage.

Method of improving the aroma and flavor of coffee using noble gases

A method is provided for improving an enzymatic process using at least one enzyme having pectinase activity which entails contacting the at least one enzyme during the process with a noble gas, mixture of noble gases or gas mixture containing at least one noble gas.

Method of improving processes using pectinase enzymes with noble gases

A method of controlling at least one browning reaction in a food, which entails effecting at least part of the reaction in the presence of at least one noble gas, a mixture of noble gases or a gaseous mixture containing at least one noble gas, thereby controlling the browning reaction.

Method of controlling browning reactions using noble gases

A process for preserving the color of red meat, which entails contacting the meat with an effective amount of an atmosphere selected from the group consisting of a noble gas, a mixture of noble gases and a mixture containing at least one noble gas and a carrier gas, the noble gas in the mixture with the carrier gas being selected from the group consisting of argon, neon, xenon an krypton and being present in said mixture in an amount of greater than about 10% by volume.

Preservation of color of stored meat using noble gases

A method of maintaining carbon dioxide concentration in an aqueous solution containing the same, which entails introducing an amount of a gas into the aqueous solution sufficient to maintain a desired level of carbon dioxide in the aqueous solution, the gas containing from about 25-100% by volume of argon and from about 0-75% by volume of a carrier gas therefor.

Method of disinfecting fresh vegetables by processing the same with a

A method for regulating enzyme activity, which entails contacting one or more enzymes with a gas containing one or more noble gases or mixtures thereof.

Method for regulating enzyme activities by noble gases

A method of washing one or more fresh vegetables, which entails washing the one or more fresh vegetables with at least one aqueous liquid containing at least an antimicrobially effective amount of dissolve carbon dioxide, and at least an amount of dissolved argon effective to inhibit bleaching and oxidizing effects of carbon dioxide.

A process for producing high fructose corn syrup from glucose containing syrup, which entails isomerizing the glucose containing syrup through an enzymatic reaction to make high fructose corn syrup, wherein the enzymatic reaction occurs in a gas containing solution which comprises at least one gas selected from the group consisting of noble gas.

Method of producing high fructose corn syrup from glucose using noble

A method for regulating enzyme activity, which entails contacting one or more enzymes with a gas containing one or more noble gases or mixtures thereof. The activity of an enzyme on a substrate can be improved by contacting the enzyme with a noble gas under specific temperatures and pressures. The preferred noble gases are krypton, neon, xenon, argon or mixtures of these gases. The enzymes whose activity can be improved are hydrolases, lyases, isomerases and ligases.

Method for improving enzyme activities with noble gases

A method of effecting increased performance of diagnostic enzyme reaction systems which includes contacting at least one reagent of an enzyme-diagnostic kit during use of the reagent in conjuction with the kit with a noble gas, mixture of noble gases or gas mixtures containing at least one noble gas.

Method of effecting increased performance of diagnostic enzyme reaction

The activity of a lipase is improved in processes where the lipase is contacted with a noble gas. The gases neon, argon, xenon, and krypton when contacted with the lipase improve the activity of the lipase when the process is performed at a pressure less than 100 atmospheres.

Method of improving lipase activity using noble gases

A method of detecting at least one noble gas through a semi-permeable membrane, allowing the permeating noble gas to contact an enzyme, the activity of which is changed by the noble gas, and detecting the change in enzyme activity.
