Decapsulated artemia egg preparation method improving hatching rate

Abstract

The invention relates to a Decapsulated artemia egg preparation method improving the hatching rate, and belongs to the technical field of artemia eggs. The decapsulated artemia egg preparation method improving the hatching rate includes the steps: taking haw as the raw material, juicing the haw, and performing dydration on artemia eggs by means of the haw juice with organic acidity and light salt brine; and by coordination of bile and phosphatidase C, decomposing the phosphatide and cholesterol in the eggshells of the artemia eggs, and by coordination of Candida rugosa bacterium and the lipoprotein lipase and active substance secreted from the Candida rugosa bacterium, and papain, decapsulating the artemia eggs, wherein the egg envelopes of the decapsulated eggs have high resistance to papain and lipoprotein lipase so that the reaction can be terminated even no special inhibitor is used and the decapsulated artemia eggs can be obtained. Through the decapsulated artemia egg preparation method improving the hatching rate, the hatching rate of the obtained decapsulated artemia eggs is greatly improved when the decapsulated artemia eggs are hatched, and achieves 93-96%. Moreover, the decapsulated artemia egg preparation method improving the hatching rate is stable in the decapsulating effect and is low in the operating difficulty.

Description

technical field [0001] The invention relates to a method for preparing shelled artemia eggs for improving hatchability, and belongs to the technical field of artemia eggs. Background technique [0002] Artemia, also known as Artemia, is a small beetle distributed worldwide, living in high-saline waters such as salt lakes and salt pans. Artemia eggs are high-quality bait for aquatic fry and play an important role in aquaculture. Artemia eggs are iron-containing lipoproteins, which cannot be digested by young fish and shrimp. Therefore, it is generally necessary to hatch Artemia larvae first, and then feed the larvae as bait. The hatched egg shells and larvae are not easy to be completely separated, and it is easy to cause part of the hatched larvae to be lost with the shells, or the egg shells and larvae are eaten together, resulting in the death of fish and shrimp seedlings due to intestinal obstruction. Artemia eggs can be fed directly after shelling, and larvae can also ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: chemical methods are often used when the existing artemia eggs are shelled, and the reaction cannot be terminated immediately after shelling, and the residual chlorine on the surface of the shelled eggs continues to act on the shelled eggs, making the shelled eggs Membrane damage is relatively large, and the temperature of the solution increases during shelling, which affects the hatching rate. A kind of organic acid is provided to soften the egg shell, and biological enzymes and bile are compounded to decompose and dissolve the egg shell to shell Artemia eggs to prepare shelling. The method for shelling Artemia eggs, the present invention first uses hawthorn as a raw material to squeeze the juice, and the hawthorn juice containing organic acids and light salt water are used to hydrate the Artemia eggs, and then the bile and phospholipase C are used to make the Artemia egg shells Phospholipids and cholesterol are decomposed, and then Candida rugosa and its secreted lipoprotein lipase, active substances and papain are used to shell Artemia eggs, and the egg membranes of shelled eggs are resistant to papain and lipoprotein lipase Strong resistance, the reaction can be terminated without using special inhibitors, and the shelled Artemia eggs can be obtained. The hatching rate of the shelled Artemia eggs obtained by the present invention is greatly improved, reaching 93-96%. , and the shelling effect of the present invention is stable, and the operation difficulty is low
