摘要

PURPOSE: Provided are a manufacturing process of a freeze-dried product of grain, vegetables, fruits and edible seaweeds treated by heated steam process and the freeze-dried product produced thereby. Therefore, the freeze-dried product maintains characteristic properties including taste, nutrients, color, etc., and controls E. coli on the its surface effectively. CONSTITUTION: The manufacturing method comprises the steps of: washing raw ingredients selected form the group consisting of grain, vegetables, fruits, and edible seaweeds, with purified water repeatedly; spraying heated steam on the ingredients through a nozzle for 20-60 seconds while passing the ingredients through a tunnel with a conveyer, to sterilize microorganisms, such as E.coli and the like; placing them on a tray; and quick freezing then freeze-drying them.
