Embodiment Construction

[0004] The ultra-high pressure sterilization and fresh-keeping method for sea cucumbers of the present invention includes the following steps:

[0005] (1) Put the packaged sea cucumbers into the liquid pressure medium in the ultra-high pressure container;

[0006] (2) Pressurize the sea cucumber to 500~800MPa for the first time, and release the pressure after maintaining the pressure for 5~30Min;

[0007] (3) Pressurize the sea cucumber to 500~800MPa for the second time, and keep the pressure for 5~30Min before releasing the pressure;

[0008] (4) Pressurize the sea cucumber to 500~800MPa for the third time, and release the pressure after maintaining the pressure for 5~30Min;

[0009] (5) Store the processed sea cucumbers at 0~5℃.

[0010] The sea cucumber treated with the technical scheme of the present invention can kill most of the bacteria, meet the aseptic requirements of commercial export, and the fresh-keeping period can be extended to more than 6 months.

Abstract

The invention discloses an ultrahigh-pressure sterilization fresh-keeping method for a sea cucumber, which fulfills the aims of sterilization and fresh-keeping by changing pressure parameters and can effectively prolong the fresh-keeping time of the sea cucumber. The technical scheme for implementing the method comprises that the sealed and packed fresh sea cucumber is put into a liquid pressure medium in an ultrahigh-pressure container and then is subjected to a circulating process of compression, pressure maintenance and decompression once to thrice under the pressure of 500 to 800MPa and the pressure maintenance time of 5 to 30 minutes. The ultrahigh-pressure treated sea cucumber can keep the primary flavor and nutrient components of the sea cucumber unchangeable, and can meet the sterile requirement of commercial export; and the fresh-keeping time of the sea cucumber can be prolonged to over 6 months at the temperature of between 0 and 5 DEG C.

Description

Technical field [0001] The invention relates to the preservation of food, in particular to a method for ultra-high pressure sterilization and preservation of sea cucumbers. Background technique [0002] Sea cucumber is the first of the eight treasures of seafood, with obvious health care functions and extremely rich active ingredients. Due to the rapid autolysis of sea cucumbers, for long-term storage and long-distance transportation, the method of processing live sea cucumbers into dried sea cucumbers is mostly adopted at home and abroad. However, the process of processing live sea cucumbers into dried sea cucumbers will inevitably cause the sea cucumbers to lose part of their nutrients and lose their original flavor. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a sea cucumber ultra-high pressure preservation method that is pollution-free, can keep the original flavor and nutritional components of the sea cucumber un...
