A gas hydrate is a crystalline solid; its building blocks consist of a gas molecule surrounded by a cage of water molecules. Thus it is similar to ice, except that the crystalline structure is stabilized by the guest gas molecule within the cage of water molecules. Many gases have molecular sizes suitable to form hydrate, including such naturally occurring gases as carbon dioxide.
Although carbon dioxide has been used in gas form for centuries to enhance the sensory of food, it is not found in the market that solid form of CO2 (dry ice) is used for taste purpose. This could be due to instability of dry ice and difficulties to control amount of dry ice distributed in food.
The firm Coca ColaTM has proposed a method for preparing a frozen carbonated beverage concentrate that remains stable at home freezer temperatures as well as commercial freezer temperatures, and a frozen carbonated beverage produced by said method (se US patent 685824). In this method, the gas hydrate is used to produce an instant carbonated drink, rather than to use the gas hydrate itself to enhance the taste of a food.
It can be easily imagined that other gas which can form gas hydrate can be used the same way.
According to the present method:
1) carbonate gas hydrate is used to enhance the taste / sensory perception of a soft drink (Jelly juice) in a manner of ingredient. The gas hydrate is distributed in...
