The invention discloses a production method of prototrophy fresh sea cucumbers without being refrigerated. The production method is characterized by comprising the following steps: taking fresh and live sea cucumbers as raw materials; and carrying out
seawater washing, water molecule purification, vacuum heating treatment, sand mouth removal, cold sterilizing, water draining, automatic stretching, filling, sterilizing and
nitrogen charging packing and spraying and sterilizing to obtain purely natural fresh sea cucumbers which are produced by non-water method, can be stored and preserved at normal temperature, have reduced
nutrition loss, taste good and are ready to be served. By a vacuum low-temperature
steaming and curing process and a closely linked sterilizing process, the original
nutrition of the sea cucumbers are retained well, the quality and the
flavor of the fresh sea cucumbers are improved, any preservatives are not used, any
flavoring agents are not added, consumption demands of people are met, healthful and nutritional
modern life demands are met, meanwhile, by
nitrogen-filled packing, the shapes of sea cucumbers in bags can be protected well, thorns of the processed sea cucumbers are complete, the original texture,
flavor and
nutrition can be maintained well at normal temperature, the
expiration date is long, the safety is high, and the sea cucumbers are convenient to eat.
