The invention discloses a preparation method of low-salt minced spanish mackerel gel based on egg white protein, and belongs to the field of food processing. The preparation method comprises the following steps: S1, blending spanish mackerel to obtain minced spanish mackerel meat; s2, adding salt into the minced spanish mackerel meat, and blending to obtain low-salt minced spanish mackerel meat; s3, egg white protein is added into the low-salt minced spanish mackerel for blending, and low-salt egg white protein-minced spanish mackerel is obtained; and S4, performing two-stage heating on the low-salt egg white protein-minced spanish mackerel fillet to obtain the low-salt minced spanish mackerel fillet gel. According to the preparation method disclosed by the invention, the egg white protein is used for replacing spanish mackerel protein, so that the texture property of the low-salt minced spanish mackerel gel is improved, the indexes such as gel strength, water binding capacity and cooking loss of the low-salt minced spanish mackerel gel are ideal, and the network structure is more uniform and compact.

The utility model relates to the technical field of cutting machines, and discloses a frozen spanish mackerel cutting machine which comprises two connecting plates, a conveying belt is arranged between the connecting plates, bearing plates which are evenly distributed are arranged at the top of the conveying belt, and a rotating rod penetrates through one side of each bearing plate and is fixedly connected with the same. One end of the outer ring of each rotating rod is rotationally connected with fixing blocks which are uniformly distributed, the fixing blocks penetrate through the bearing plate and are in sliding connection with the bearing plate, one end of each fixing block is provided with a needle head, the outer ring of each rotating rod is sleeved with torsional springs which are uniformly distributed, one end of each torsional spring is in contact with the corresponding fixing block, and the other end of each torsional spring is in contact with the bearing plate. According to the fish cutting device, the movement of a fish body in the cutting process can be effectively prevented through the linkage among the inserting groove, the connecting rod, the first spring, the limiting rod, the scraping plate, the rotating rod, the fixing block, the torsional spring and the needle head, so that the cutting accuracy and uniformity are improved, and the consistent cutting effect of each section of fish meat is ensured.

The application provides a breeding method of blue dot jack mackerel, which is screening molecular markers linked to growth traits by analyzing microsatellite primer amplification products of a fast growth group and a slow growth group of the blue dot jack mackerel, and screening parents for genetic breeding of the blue dot jack mackerel by using the screened molecular markers. The application obtains microsatellite markers linked to growth traits of the blue dot jack mackerel by analyzing amplification products of different growth traits of the blue dot jack mackerel, and the microsatellite markers can be used to screen blue dot jack mackerel individuals with better growth potential, thereby providing effective molecular markers for genetic breeding operation of the blue dot jack mackerel.

The invention provides an artificial breeding method for mackerel squalane fry, namely, on the basis of screening molecular markers related to vibrio resistance characters of squalane squalane, the artificial breeding method for the mackerel squalane fry is established, and the squalane squalane fry with vibrio resistance is cultivated. According to the SNP site molecular marker linked with the blue-point Chimaera anti-vibrio disease character, the SNP site molecular marker is located at the 130 site of the sequence SEQ ID NO: 1, and the basic group of the SNP site molecular marker is C / T. The molecular marker related to the vibrio resistance character of Chimaera blue-dot is obtained through screening and is used for screening disease-resistant parents, so that the disease-resistant genetic breeding speed of Chimaera blue-dot is increased, and the breeding efficiency and the breeding survival rate of disease-resistant strains are improved.

The application discloses a nondestructive detection method for biological amine of Spanish mackerel based on Raman spectrum technology, and belongs to the technical field of food nondestructive detection. ‑1 The method first cuts fresh Spanish mackerel into pieces and refrigerates the pieces for different lengths of time to prepare different freshness samples, collects Raman spectra of the samples in the range of 400-2000 cm ‑1 under 532nm laser light, simultaneously determines the histamine, putrescine and cadaverine content in the samples by HPLC, carries out principal component analysis on the spectrum baseline correction and normalization, realizes accurate classification of the freshness of Spanish mackerel by combining LDA, SVM and RF machine learning models, the accuracy of the SVM model reaches 100%, the spectrum characteristic variables are screened by CARS, PLSR and SVR regression models are established, and accurate quantification of the three core biological amine is realized, and the prediction correlation coefficients are all higher than 0.9. The application is nondestructive, rapid and convenient to operate, improves the early warning sensitivity of Spanish mackerel corruption, can effectively avoid the risk of excessive histamine, and also provides technical reference for biological amine detection of similar marine products.
