<p>PURPOSE:To readily retain freshness of a food for a long period at a low cost by dipping a cooled water-containing food in an aqueous solution of a specific substance heated to a specified temperature, naturally drying the resultant food and then forming an airtight thin film on the surface of the food. CONSTITUTION:An aqueous solution of a tasteless, odorless and nontoxic substance (e.g. gelatin) solidifiable at ordinary temperature is heated to 40-60 deg.C and a water-containing food (e.g. fish or cut surfaces of bisected grapefruit, etc.) precooled to 4-6 deg.C is dipped in the aforementioned heated aqueous solution, then taken out and naturally dried to carry out the objective retention of the freshness.</p> |
