HYDROGEN GAS-CONTAINING ICE AND ITS MAKING METHOD, AND FRESH FOOD PRESERVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen gas-containing ice for keeping a reducing atmosphere for a long period even in an incompletely sealed container while preventing the decay of fresh fishes and suppressing the progress of discoloration, and to provide its making method and a fresh food preserving method. SOLUTION: The method is provided for preserving fresh foods packaged with the hydrogen gas-containing ice in the container. The hydrogen gas-containing ice is made by icing after dissolving hydrogen gas or a mixture of hydrogen gas and inactive gas in raw material water. COPYRIGHT: (C)2007,JPO&INPIT
