PURPOSE:To prepare a food having a good tooth touch while retaining the components, quality, volume, etc., of the raw material, by freezing a granular raw mateiral, freezing-coating the granular raw material with a coating material and subsequently lyophilizing the coated raw material in vacuo. CONSTITUTION:A liquid raw material such as the juice of a fruit or vegetable, e.g. strawberry or spinach, tea or liquor is mixed with a dry powder material (a material prepared by lyophilizing the same material as the raw material in vacuo and subsequently pulverizing the product) to adjust the water content thereof, pouring in a mold, frozen in a freezer at <=-25 deg.C and subsequently cutting with a cutter, etc., into 6-12mm square frozen granules. The -25 deg.C granules and a -2 deg.C coating material (e.g. sugar or defatted milk) are charged in a revolving machine and repeatedly subjected to coating operations until the granules are coated in a constant thickness. The coated granules are lyophilized with a vacuum lyophilizer in vacuo at 30 deg.C (electrically heated) to provide the objective food. |
