The invention relates to a making method of instant fresh
sea cucumber, which is characterized by comprising the following steps: opening the
abdomen of a fresh and live
sea cucumber, completely removing internal organs, washing with clear water, placing into
manganese salt solution which is 1-10 times the weight of the
sea cucumber, adding an
organic acid for adjusting the pH value to 4.0-6.0, placing the whole into a
microwave sterilizer for
microwave heating to 40-75 DEG C, and performing heat insulation treatment for 5-60 minutes; taking the sea cucumber out of the solution, and using
ethanol solution containing 0.1-1% of tea
polyphenol and 0.1-10% of
propolis for impregnation or spraying the
ethanol solution on the outer surface and the outer surface of the body wall of the sea cucumber; and performing compound
modified atmosphere packaging on the sea cucumber so as to get the instant fresh sea cucumber. The instant fresh sea cucumber made through the method is low in loss of nutritional ingredients, the
heat denaturation of
protein is avoided, the instant fresh sea cucumber further has good taste and no fishy and astringency smell, and is convenient to preserve and take, simple in
processing technology, short in period and low in
energy consumption, and subsidiary ingredients can further increase the health care function of the sea cucumber while being used for
processing.
