Embodiment 1

[0019] A method for producing dried Antarctic krill products carried out on board specifically includes the following steps:

[0020] (1) Pretreatment: Clean the freshly caught Antarctic krill with seawater, sort out miscellaneous fish, weeds and unqualified krill, etc., ensure that the krill damage rate is below 0.1%, and select large-sized Antarctic krill (45mm <body length), and the krill meeting this specification is more than 95%;

[0021] (2) Boil in water: put 1kg of the large-scale Antarctic krill pretreated in step (1) into a cooking pot and boil, add 0.01kg of salt, heat the water to 80°C, keep at this temperature for 15 minutes, remove it, and Drain the Antarctic krill;

[0022] (3) drying: adopt 60 ℃ of hot air to dry, through about 1 hour, make the water weight content in Antarctic krill be reduced to 18-20%;

[0023] (4) Packaging: the dried Antarctic krill products are usually sealed and packaged.

Embodiment 2

[0025] The production method of the Antarctic krill dried product that the present invention carries out on board specifically comprises the following steps:

[0026] (1) Pretreatment: Clean the freshly caught Antarctic krill with seawater, sort out miscellaneous fish, weeds and unqualified krill, etc., ensure that the krill damage rate is below 0.1%, and select medium-sized Antarctic krill (35 < body length ≤ 45mm), so that more than 95% of krill meet this specification;

[0027] (2) Steaming: Put 1 kg of medium-size Antarctic krill pretreated in step (1) into a cooking pot for boiling water steaming, and after steaming for 3 minutes, take out the Antarctic krill and drain;

[0028] (3) drying: adopt 50 ℃ of hot air to dry, after about 2 hours, make the moisture weight content in Antarctic krill be reduced to 18-20%;

[0029] (4) Packaging: Vacuum-seal the dried Antarctic krill products.

Embodiment 3

[0031] The production method of the Antarctic krill dried product that the present invention carries out on board specifically comprises the following steps:

[0032] (1) Antarctic krill pretreatment: Wash freshly caught Antarctic krill with seawater, sort out miscellaneous fish, weeds and unqualified krill, etc., to ensure that the krill damage rate is below 0.1%, and select medium-sized Antarctic krill Shrimp (35 < body length ≤ 45mm), so that more than 95% of krill meet this specification;

[0033] (2) Boil in water: put 1 kg of medium-sized Antarctic krill pretreated in step 1 into a cooking pot for boiling, add 0.02 kg of salt, heat the water to 95°C, keep it at this temperature for 1 minute, and remove it. Antarctic krill drained;

[0034] (3) Drying: adopt the sun to dry, and after about 10 hours, the water weight content of Antarctic krill is reduced to 18-20%;

[0035] (4) Packing: vacuum pack the dried Antarctic krill products.

Abstract

The present invention relates to an euphausia superba dried product production method which comprises the following steps: (1) washing the caught fresh euphausia superba with seawater, conducting standard grading of the euphausia superba by small-size shrimps, middle-size shrimps and large-size shrimps; (2) putting the pre-processed euphausia superba from step (1) with the same standard into a cooking pot, conducting cooking with water or steaming with boiling water, adding edible salt, cooking with water at 75-95 DEG C or steaming with boiling water for a certain time, removing the euphausia superba and draining; (3) hot air drying or drying in the sun until the moisture content of the euphausia superba is reduced to 18-20% by weight; and (4) conducting vacuum packaging or common seal packaging of the euphausia superba dried products from step (3).

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a production process for processing Antarctic krill into dried Antarctic krill products that can be stored at room temperature or refrigerated at low temperature on a large-scale fishery processing ship in the Antarctic sea area. Background technique [0002] The body length of Antarctic krill is generally 3.0 to 5.5 cm, and the annual catchable amount can reach 100 million tons, which is equivalent to the sum of the annual fish and crustacean catches in the world (99 million tons). The largest source of protein available to humans. In recent years, the annual catch of Antarctic krill has remained at more than 100,000 tons. Generally, Antarctic krill is directly frozen and transported at -20°C for at least two months before being transported to land. Processing and utilization. [0003] Antarctic krill is rich in low-temperature enzymes, even at -20°C, it can still sl...
