This invention discloses a flavor peptide, its preparation method, and a method for adjusting the flavor of quick-brewed fish sauce, belonging to the field of biotechnology. The flavor peptide is extracted from fermented soybean paste. The flavor peptide is used to adjust the flavor of quick-brewed fish sauce: using freshwater fish and / or its processing by-products as raw materials, processing them into a meat paste, adding enzymes for enzymatic hydrolysis, inactivating the enzymes, adding the flavor peptide, inoculating with microbial agents for fermentation, and finally filtering and sterilizing to obtain the flavor-adjusted quick-brewed fish sauce. This method significantly improves the umami and thickness of quick-brewed fish sauce and harmonizes the taste and flavor of the fish sauce.

The application provides a vaccine against ichthyophthiriasis and a preparation method and application thereof, and belongs to the technical field of fish disease prevention and control. The application uses inactivated whole worms of in-vitro large-scale cultured Amphilina alata as a cross antigen, and fish complement C5a protein as an immunoadjuvant, and the two synergistically play a high-efficiency immune protection role. The application mixes and emulsifies the C5a adjuvant and the antigen at an effective dose of 1x10 4 6x10 4 per tail to prepare the vaccine. After intraperitoneal injection and secondary boosting, the vaccine produces significant cross protection against the infection of the ichthyophthirius, and the protection effect is significantly better than that of a traditional Freund's adjuvant vaccine. The application breaks the bottleneck that the ichthyophthirius cannot be cultured in vitro and thus a large number of worm bodies cannot be obtained for large-scale preparation of whole worm vaccines, and also solves the problem of poor safety of traditional adjuvants, has the advantages of low cost, good effect, easy large-scale production and the like, and is suitable for green immune prevention and control of ichthyophthiriasis of freshwater fish.

The application discloses a kind of preparation method of freshwater fish fish round, belong to food processing technical field, it includes the following steps: freshwater fish is scaled, is taken out viscera, is washed and is divided;Take fish meat 7500g, corn starch 1500g, gourmet powder 190g, chicken essence 90g, edible salt 230g, egg white 1200g, ginger juice 450g, green onion 300g, cooking wine 150g, green onion oil 600g;Fish meat and auxiliary materials are put into vacuum tumbling machine, and tumbling is 5-30 minutes under 0.05kPa;Fish paste is manually shaped into spherical, is put into 80-120 DEG C oil pot, and is placed for 1 minute, and is placed for 1 minute after turning over, is stirred and turned over to ping pong ball shape with strainer, and is taken out and is drained.Oil is raised at low temperature in the application, can avoid burst and hot oil splashing, easy to operate, without adding leavening powder and other aids, keep fish round natural flavor.
