Embodiment 1

[0031] A kind of preparation method of fish protein powder of the present invention, its steps are as follows:

[0032] (1) Preparation of surimi paste: slaughter the fish, remove scales, gills and viscera, weigh 5kg in the obtained fish body, first use food-grade chlorine dioxide to sterilize and disinfect it, and then use aseptic The water is rinsed and then minced into surimi; 5 kg of water is added to the obtained surimi, and then ground into surimi pulp.

[0033] (2) Preparation of enzymatic hydrolysis solution: heat the surimi pulp obtained in step (1) to 60°C, keep it warm for 20 minutes, and then adjust its pH value to 6.0; add 5.0 g of papain to the adjusted surimi pulp, It was hydrolyzed at ℃ for 5 hours, heated to 100℃ and kept for about 25 minutes to inactivate the enzyme, and then cooled to below room temperature to obtain the enzymatic hydrolysis solution.

[0034] (3) Prepare fish protein powder: centrifuge the enzymatic hydrolyzate obtained in step (2) to remo...

Abstract

The invention provides a fish protein powder which is water soluble with the color between light-yellow and pale-brown meal, wherein, the dry basis protein content of the fish protein powder is more than 80%; and a preparation method is provided for the fish protein powder. The method comprises the following steps: (1) preparing mincedfish seriflux; (2) preparing enzymatic hydrolyzate by the mincedfish seriflux; (3) preparing the fish protein powder by the enzymatic hydrolyzate. The fish protein powder prepared in the invention has the advantages of health, easy digestion, easy absorption, and the like; and can be widely used on protein-enhanced foods; the production process is simple, the production efficiency is high, and the raw materials have wide sources and can be obtained easily, thereby helping save cost.

Description

technical field [0001] The invention relates to protein powder production technology, in particular to a fish protein powder and a preparation method thereof. Background technique [0002] Protein powder products prepared from protein hydrolyzate are not only superior to amino acids in absorption mechanism, but also have a variety of physiological functions that are incomparable to amino acids and original proteins. At the same time, the physical and chemical properties and sensory properties of protein powder have been improved to varying degrees compared with the original protein. [0003] In recent years, with the rise of protein powder products, people are increasingly aware of the importance of peptides. The crude protein content in fish meat is as high as 15%, and the essential amino acids contained in it are complete. There are functional regions commonly found inside the polypeptide chains of fish proteins. By selecting suitable proteases to hydrolyze these polypep...
