A livestock-poultry meat modifier containing lycopene consists of the following components in percent by mass: 5-10 lycopene, 10-20 vitamin E, 0.015-0.03 selenium, 0-0.02 chromium, and the balance of carrier. The meat modifier can be prepared by the following steps: dissolving the lycopene solid powder by a small amount of normal hexane, mixing gelatin and sucrose in mass ratio of 3:7-1:9 to form microcapsule wall material, and conducting homogenization, wherein the mass of the lycopene solid powder accounts for 10-20% mass of the mixture of the gelatin and the sucrose; and mixing the lycopene microcapsule with the vitamin E, the selenium and the chromium in mass ratio, and then adding the blance of carrier. The livestock-poultry meat modifier containing lycopene is added in livestock-poultry complete feed, in 0.05-0.1 percent by weight. Tests prove that the meat modifier can reduce occurrence of PSE meat, effectively inhibit muscle fat oxidation, increase muscle water holding capacity, reduce muscle drip loss, stabilize meat color and improve meat tenderness, maintain meat flavor and prolong the shelf life of meat.

The invention provides a mineralized collagen artificial periosteum. The artificial periosteum is made of mineralized collagen in which nano calcium phosphate and collagen fibers are arranged in an orderly manner. It has the same material composition and microscopic and macroscopic structure as the natural periosteum, and has good Mechanical properties and biodegradable properties can be used for periosteum replacement and repair. The artificial periosteum of the present invention can limit other bone grafting materials to the bone defect during the repair process, avoiding bone graft material prolapse and muscle, fat and other tissues being squeezed into the bone defect, affecting the repair effect. The pore structure of the artificial periosteum is beneficial to the regeneration of blood vessels and the delivery of nutrients, thereby benefiting the repair of bone defects. Since the mineralized collagen artificial periosteum is composed of nano-calcium phosphate and collagen fibers, the artificial periosteum can be gradually degraded in vivo with the regeneration of bone tissue and periosteum. The invention also provides a preparation method of the artificial periosteum.

The invention relates to a quick evaluation method for meat grades of raw northern bluefin tuna, and belongs to the field of aquatic foods. The quick evaluation method is characterized in that on thebasis of quality characteristics of the northern bluefin tuna, a sensory evaluation method is adopted, and the meat grades of the raw northern bluefin tuna are divided into the excellent grade, the good grade and the common grade according to the muscle fat textures and muscle colors at cross sections of back and abdomen. The sensory evaluation method has the advantages of intuition, rapidity andoperability in the meat quality evaluation of the raw northern bluefin tuna, so that the original appearance and quality of the product can be furthest maintained, and the requirements of convenient operation, rapidity, practicality and the like in the market trade grade evaluation and inspection can be met.

The invention discloses a method for improving the correct rate of authenticity identification of meat sources based on hyperspectral image processing. The background mask image is constructed based on the band ratio image, and then the second principal component image of the hyperspectral image is extracted by principal component analysis method, and the background of the second principal component image is segmented, and then the fat mask image is constructed to realize the detection of the background in the hyperspectral image. and fat removal; then extract the spectral characteristics of the target object, and use the principal component analysis method to reduce the dimensionality of the spectral characteristics, and input the model for training and detection, which can improve the accuracy of the identification of the authenticity of the meat source. The invention uses hyperspectral image processing technology to remove the background and intermuscular fat, and improves the correct rate of identifying the authenticity of the meat source.

Construction of a recombinant adenovirus vector of an NRIP1 (nuclear receptor interacting protein 1) gene of Qinchuan cattle can be applied to gene function research and dentification on Qinchuan cattle NRIP1, reconstruction of seed cell, regulation on gene metabolism of muscle, fat and reproduction, etc. The Qinchuan cattle NRIP1 gene is inserted under a CMV promoter of a pAdTrack-CMV adenovirusshuttle plasmid to construct a recombinant shuttle plasmid pAdTrack-CMV-NRIP1. After linearization, a PmeI transforms an E.coli BJ5183 competent cell containing a pAdEasy-1 plasmid; an efficient homologous recombinant system of a Cre recombinase in the E.coli BJ5183 is utilized to complete homologous recombination of pAdTrack-CMV-NRIP1 and pAdEasy-1 in bacteria. A correct recombinant adenovirus plasmid is named as pAd-NRIP1. After digestion linearization of pAd-NRIP1 by a PacI, a liposome is transfected to a 293A cell, so as to obtain a recombinant virosome.
