Embodiment 1

[0017] Small yellow croaker preservation process, the specific operation steps are:

[0018] 1) Soaking in acid solution: Wash the small yellow croaker, drain, soak in bamboo vinegar solution, the pH of bamboo vinegar solution is 2.5~3.5, the color is reddish brown, the temperature is 6~12°C, and the soaking time is 15~20min. Bamboo vinegar liquid is a liquid substance obtained by collecting the gas produced in the pyrolysis of bamboo in the process of burning bamboo charcoal, and cooling the gas at room temperature. It does not contain antibiotics and conventional fungicides, is safe and environmentally friendly, and has a broad spectrum Antibacterial effect; has anti-oxidation effect, can inhibit the oxidative rancidity of fat in the storage process of small yellow croaker, thereby prolonging the storage period and shelf life of small yellow croaker;

[0019] 2) Soaking in compound preservation solution: Drain the small yellow croaker treated in step 1 and soak in compound p...

Embodiment 2

[0023] The most preferred operation steps for the fresh-keeping process of small yellow croaker are:

[0024] 1) Soaking in acid solution: Wash the small yellow croaker, drain it, and soak it in bamboo vinegar solution. The pH of the bamboo vinegar solution is 3, the color is reddish brown, the temperature is 7°C, and the soaking time is 18 minutes. Bamboo vinegar liquid is a liquid substance obtained by collecting the gas produced in the pyrolysis of bamboo in the process of burning bamboo charcoal, and cooling the gas at room temperature. It does not contain antibiotics and conventional fungicides, is safe and environmentally friendly, and has a broad spectrum Antibacterial effect; has anti-oxidation effect, can inhibit the oxidative rancidity of fat in the storage process of small yellow croaker, thereby prolonging the storage period and shelf life of small yellow croaker;

[0025] 2) Soaking in compound preservation solution: Drain the small yellow croaker treated in step ...

Abstract

The invention provides a pseudosciaena polyactis fresh-keeping method. The pseudosciaena polyactis fresh-keeping method comprises following steps: 1, acid solution immersion; 2, composite fresh-keeping solution immersion; 3, film forming; and 4, packaging and refrigeration. The beneficial effects are that: bamboo vinegar and the composite fresh-keeping solution are used for immersion bacteriostasis, no antibiotic or conventional bactericide is added, the pseudosciaena polyactis fresh-keeping method is safe, and is friendly to the environment; characteristic putrefying bacteria in pseudosciaena polyactis can be inhibited obviously, degradation speed of proteins in pseudosciaena polyactis meat is slowed down, fresh keeping degree is improved, and nutrient loss is reduced; oxidation resistance is achieved, oxidative rancidity of grease in pseudosciaena polyactis preservation process is inhibited, and the preservation period and self-life of pseudosciaena polyactis is prolonged; at the same time, sodium alginate polysaccharide gel and metal cations possess film forming performance, so that decoloring and water loss in pseudosciaena polyactis fresh-keeping process are delayed, the mouthfeel close to that of fresh pseudosciaena polyactis is maintained; operation is simple, cost is low, and market application prospect is promising.

Description

technical field [0001] The invention relates to a fish fresh-keeping technology, in particular to a small yellow croaker fresh-keeping technology. Background technique [0002] Small yellow croaker (Pseudosciaena polyatis) is also known as small yellow croaker, thick-scaled croaker, yellow croaker, big eye, flower fish, ancient fish. Vertebrates are fishes belonging to the genus Yellowcroaker of the family Perciformes of the order Perciformes, which resembles small yellow croakers, but with longer heads, smaller eyes, larger scales, short and wide caudal peduncles, and 28 to 30 vertebrae. The otoliths are larger. Body length about 20 cm. The back of the body is taupe, and the belly is golden yellow. The spawning ground is in the coastal sea area with a water depth of 10-25 meters, and the wintering ground is generally 40-80 meters. The fish school has obvious vertical movement phenomenon, rising at dusk and descending at dawn, and inhabiting the bottom or near the bottom ...
