Problems solved by technology

However, the skin color is dark and changeable, there is a lot of water, there is a lot of ink, it is easy to redden, and the skin is loose, which leads to the traditional processing methods of aquatic products such as sun-dried products, etc., which are not suitable for it.
[0003] Chinese patents CN104886225A, CN104824113A, CN104544474A, and CN103315044A all disclose fresh-keeping methods for squid, but these fresh-keeping methods are all fresh-keeping methods for processing squid slices, and do not involve fresh-keeping methods for squid transportation

Embodiment 1

[0051] Add 60 liters of tap water to the 100L squid transport container, add 90g of preservative calcium sulfate, 42g of potassium chloride, and 1800g of sodium chloride, turn on the oxygen pump and dissolved oxygen detector, control the dissolved oxygen amount to 5.00 mg / L, and control the temperature at 5 ℃; Renew the tap water and preservative every 3 hours, check the survival of the squid at all times, pick out the dead ones immediately, and record that the survival rate of the squid is 95% after 20 days.

Embodiment 2

[0053] Add 60 liters of tap water in a natural state to the 100L squid transport container, add preservative calcium sulfate 100g, potassium chloride 48g, sodium chloride 1900g, open the oxygen pump and dissolved oxygen detector, control the dissolved oxygen amount 6.00 mg / liter, The temperature was controlled at 6°C; the tap water and preservative were updated every 3.5 hours, the survival of the squid was checked at all times, and those found to be dead were picked out immediately and recorded. After 20 days, the survival rate of the squid was 95.6%.

Embodiment 3

[0055] Add 60 liters of tap water to the 100L squid transport container, add 95g of preservative calcium sulfate, 45g of potassium chloride, and 1890g of sodium chloride, turn on the oxygen pump and dissolved oxygen detector, control the dissolved oxygen amount to 6.00 mg / L, and control the temperature at 6 ℃; Renew the tap water and preservative every 3 hours, check the survival of the squid at all times, pick out the dead ones immediately, and record, the survival rate of the squid after 20 days is 96.6%.

Abstract

The invention relates to a fresh keeping agent and fresh keeping method for transportation of squids, in particular to the field of fresh keeping for transportation of aquatic products. The fresh keeping agent comprises calcium sulfate, potassium chloride and sodium chloride. The raw materials of the prepared fresh keeping agent for transportation of squids disclosed by the invention are food-grade, safe and non-toxic, so that the fresh keeping agent conforms to food safety initiated by China at present; after the fresh keeping agent for transportation of squids is used, after the squids are fished, the fresh keeping agent can be used for temporarily keeping the fished squids alive; the metabolic process in the bodies of the squids is influenced with a salt solution, the activity of the squids is reduced, the period that the squids is kept alive is prolonged, and the fresh degree of the squids is guaranteed to the maximum extent; the squids do not eat foods at the water temperature being 7 DEG C or below, so that when the fresh keeping agent and the fresh keeping method are adopted, the squids can keep alive for 20 days, and requirements of high-sea capturing can be met; and besides, through the technical scheme of the fresh keeping agent disclosed by the invention, the components are in micro adjustment, so that the fresh keeping agent can be suitable for fresh keeping of transportation of various cephalopod aquatic organisms.

Description

technical field [0001] The invention relates to the field of aquatic product transportation and preservation, in particular to a squid transportation preservation agent and a preservation method thereof. Background technique [0002] Squid, also known as calamari and squid, has high nutritional value and is a rare seafood. It has basically the same nutritional function as cuttlefish, octopus and other mollusk brachiopod seafood. They are rich in protein, calcium, phosphorus, iron, etc., and contain very rich trace elements such as selenium, iodine, manganese, and copper. The nutritional value of squid is very high. It is rich in protein, calcium, taurine, phosphorus, vitamin B1 and other nutrients needed by the human body, and the content is extremely high. In addition, the fat content is extremely low. However, the skin color is dark and volatile, with a lot of moisture, ink, easy to redden, and loose skin, which makes traditional aquatic product processing methods such a...
