The present invention relates to frozen delicacies from land and a preservation technology of the delicacies from land, and belongs to the field of food preservation. The preservation technology comprises the following steps: raw materials of the delicacies from land are placed in a liquid nitrogen environment at -120 DEG C to -60 DEG C or a micro-freezing liquid environment at -40 DEG C to -25 DEG C to be quick-frozen for 5 min or longer, then the quick frozen delicacies from land are sent into a storage to be cold stored, and the cold stored delicacies from land are subjected to a cold chain transportation. The raw materials of the delicacies from land comprise bamboo shoots and edible fungi. The technological process is simple, easy to operate, excellent in preservation effects and low in costs. The obtained delicacies from land by the above technology are good in mouthfeel, and small in dry consumption rate, and can keep freshness of the raw materials for a long time.
Description
