The present invention relates to a continuous inoculation method in a fermented product of food, particularly fermented food, wherein the freeze-concentrated fermented product is thawed using a microwave device or a water bath thawing device that operates in a container containing the freeze-concentrated fermented product. The thawed concentrated fermented material is continuously injected into the liquid stream inoculated from the container.本願発明は、食品、特に発酵食品の発酵体での連続植菌方法に関し、ここで、凍結濃縮発酵体は、凍結濃縮発酵体を含むコンテナで作動するマイクロ波装置又は水浴解凍装置を用いて解凍され、解凍濃縮発酵体は、コンテナから植菌される液体の流れに連続的に注入される。
