Method of improving processes using pectinase enzymes with noble gases

A method for enhancing pectinase activity in an enzymatic process using at least one enzyme having pectinase activity, which comprises:

• a) injecting a gas into a fruit or fruit juice containing at least one enzyme having pectinase activity, the gas consisting essentially of argon, neon, krypton, xenon or a mixture thereof;
• b) saturating the fruit or fruit juice with the gas to an extent of at least 50% of full saturation of said fruit or fruit juice with said gas;
• and
• c) maintaining the saturation substantially throughout the fruit or fruit juice, and during said enzymatic process at a temperature of from 10 to 30° C. and at a pressure of less than 10 atm.
