Embodiment 1

[0018] Embodiment 1: the preparation method of enzymatic hydrolysis fresh silver carp protein powder

[0019] According to the method described in the present invention, fresh silver carp is slaughtered, and its viscera, gills, etc. are removed, and after cleaning, it is placed in a plastic transfer basket to drain, and it is roughly crushed by a meat grinder with a screen aperture of 12 mm; coarsely crushed The final silver carp meat was packed into PE bags and spread flat on the metal tray dedicated to electron beam irradiation. The thickness of the raw meat was controlled to be basically uniform and the thickness was not more than 6.0 cm. The technical parameters of high-energy electron beam radiation treatment were that the output energy of the electron beam was 10MeV, the distance between the high-energy electron beam scanner and the product is 520mm, the scanning frequency is 200pps, the scanning width is 500 mm, the transmission speed of the radiation tray under the scan...

[0020] Embodiment 2: the preparation method of frozen saury enzyme hydrolyzed protein powder

[0021] According to the method of the present invention, the frozen saury is thawed, and the thawing can adopt the flowing water method. After the thawing is completed, remove its internal organs, fish gills, etc., and put it in a plastic transfer basket to drain after cleaning. The aperture of the mesh plate is 12mm. The coarsely crushed meat grinder; the coarsely crushed fish meat is put into PE bags and spread flat on the metal tray dedicated to electron beam irradiation, so that the thickness of the raw meat is basically uniform and the thickness does not exceed 6.0 cm. High-energy electron beam radiation treatment technology The parameters are that the output energy of the electron beam is 10 MeV, the distance between the high-energy electron beam scanner and the product is 520 mm, the scanning frequency is 300 pps, and the scanning width is 500 mm. The transmission speed of the ...

Embodiment 3

[0022] Example 3: Preparation method of enzyme hydrolyzed protein powder for processing eel leftovers

[0023] According to the method of the present invention, usually processed eel leftovers are frozen products, and the raw materials need to be thawed. After thawing, impurities such as larger bones in the raw materials are removed. After cleaning, they are placed in a plastic transfer basket and drained. The 10mm meat grinder is coarsely crushed; the coarsely crushed fish meat is put into PE bags, and spread flat on the metal tray dedicated to electron beam irradiation. The thickness of the raw materials is basically uniform and the thickness does not exceed 6.0 cm. High-energy electron beam radiation treatment technology The parameters are that the output energy of the electron beam is 10MeV, the distance between the high-energy electron beam scanner and the product is 520mm, the scanning frequency is 300pps, the scanning width is 500 mm, the transmission speed of the radiat...

Abstract

The invention discloses a method for preparing hydrolyzed fish protein powder by utilizing electron beam irradiation and combining an enzymolysis technology, and belongs to the technical field of aquatic product deep processing. The main process of the method comprises the following steps: adding maltodextrin, emulsified starch and the like after washing and carrying out crushing by a meat grinder, electron beam irradiation and enzyme hydrolysis on (fresh, refrigerated or frozen) fish, and carrying out spray drying after emulsifying and homogenizing, thus finally obtaining the hydrolyzed fish protein powder. According to the method disclosed by the invention, electron beam irradiation treatment is carried out before enzyme hydrolysis of fish protein, so that the tissue structure of the fish protein can be loosened, the protein degradation during the enzyme hydrolysis of the fish protein is facilitated, and the efficiency of enzyme can be greatly increased; irradiation also realizes a sterilization effect, so that all kinds of microorganisms in raw materials can be effectively controlled, and a working procedure of cooling after heating during the enzyme hydrolysis is not needed; hydrolyzed fish protein liquid can be emulsified and homogenized before spray drying, the effect of carrying out microencapsulated embedding treatment on fatty acid grease in the raw materials of fish is obtained, the oxidization level of the fatty acid grease in a product processing and storing processes is reduced, and the product quality is enabled to be more stable.

Description

technical field [0001] The invention discloses a method for preparing hydrolyzed fish meat protein powder by using electron beam irradiation combined with enzymatic hydrolysis technology. The invention belongs to the technical field of deep processing of aquatic products and relates to fresh-keeping processing of aquatic products. Background technique [0002] The comprehensive technology of deep processing of aquatic products and its application is an important continuation of the fishery industry.
