example 1

[0008] Example 1. Put 2000 grams of eel and loach into clear water ponds for 2 to 3 days, and then transfer them to another clear water pond for precooling and disinfection with nitrogen; Control it below -19°C, classify the pulverized particles, control D 97 ≥300 mesh, finally carry out low temperature and vacuum drying, the temperature is controlled below -30°C, and 500 grams of eel powder of 300 mesh and 440 grams of loach powder of 300 mesh are obtained. Treat dry rice field eel powder and dry loach powder respectively with 1.5% (weight) selenium-enriched tea polyphenols (selenium content 0.068 mg / kg, tea polyphenols content ≥ 98%) with a homogenizer for several minutes, and use microwave penetration after packaging After the disinfection treatment, two products, the selenium-enriched eel powder and the selenium-enriched loach powder functional food base material and the health care medicine industry base material, are obtained.

example 2

[0009] Example 2. Put 250 grams each of the selenium-enriched eel powder and selenium-enriched loach powder obtained in "Example 1" into a homogeneous mixer for 20 minutes, and then quantitatively pack the two 300-mesh powders that have been homogenized into capsules , Just get "Selenium-enriched Loach and Eel Capsule" health medicine.

example 3

[0010] Example 3, 2000 grams of whole grass carp was obtained by the same process in "Example 1" 97 Grass carp fish meal of ≥200 mesh and 420 grams (remove >78.6% water content), the 200 mesh grass carp fish meal is crushed and classified to the cell-breaking particle size in a collision jet mill, D 97 ≥1250 mesh. Put 420 grams of cell wall-breaking ultrafine grass carp powder into a supercritical extraction kettle for carbon dioxide extraction, keep the pressure in the extraction kettle at 30-31Mpa, and extract at a temperature of 70-80°C for 25 minutes, then use chromatographic separation to obtain the purity> 98%, polyunsaturated fatty acids (DHA, EPA) with an extraction rate of 95-99%, have obtained a medical industry base material with unique curative effects on cardiovascular and cerebrovascular diseases.

Abstract

The present invention relates to fish processing method, and is process of preparing fine fish powder and superfine fish powder and extracting medicine component from fish. Under low temperature, fish is crushed and dried to obtain basic fish powder. The basic fish powder is further airflow crushed to obtain superfine fish powder, and the superfine fish powder is supercritical CO2 extracted to obtain medicine component. The present invention has whole fish processed to obtain fine fish powder and superfine fish powder and can maintain all the effective components and nutritive components of fish. The supercritical CO2 extraction process with cell wall crushing powder as material can obtain the medicinal effective component with no contamination, purity over 99 % and extraction rate over 98 %.

Description

1. Technical field [0001] The invention relates to a fish processing method, in particular to a method for preparing fine powder, superfine powder and extracting medicinal components from fish. 2. Background technology [0002] At present, the method of making fine powder and extracting medicinal ingredients from aquatic products is first to slaughter the fish, discard scales, bones, and viscera, and then, 1. heat, concentrate and dry with water to make fine powder; Crush to make a fine powder. The main shortcoming of above-mentioned preparation method: 1. The utilization rate of fish is low, only utilizes the part raw material of fish, discards the useful part in the fish to varying degrees; and loss of trace elements. 3. Contents of the invention [0003] The object of the present invention is to provide a method for preparing fine and ultrafine powder and extracting medicinal components from whole fish. [0004] The technical solution of the present invention is real...
