The application discloses a preparation method of a composite deodorization material for aquatic products. First, a psidium fruit extract is extracted by a low-temperature water extraction or boiling water extraction method, and then the psidium fruit extract is mixed with an acetic acid chitosan solution to prepare psidium fruit extract-chitosan particles. Then, the psidium fruit extract-chitosan particles are compounded with gamma-cyclodextrin, salvia officinalis extract, plant oil and other components to prepare the composite deodorization material. The psidium fruit extract is innovatively applied to the deodorization of aquatic products. Meanwhile, the active components of the psidium fruit and chitosan are stably compounded by a microencapsulation technology, and the long-acting deodorization is realized by the multiple mechanisms of cyclodextrin embedding, plant polyphenol antioxidant and other mechanisms, so that the deodorization effect of the aquatic products is effectively improved. The low-temperature plasma assisted soaking technology is applied to the preparation of the deodorization agent, which can effectively decompose the molecular structure of the fishy smell substances, improve the deodorization effect, reduce the number of microorganisms in the deodorization agent, ensure the food safety and prolong the storage period.

The invention provides an assembled and annotated chloroplast genome of euphorbia splendens, and relates to the fields of molecular biology and plant genetics. The chloroplast genome of the pteris amurensis is a single cyclic molecule; the total length of the chloroplast genome of the psidium aquilinum is 149180bp; the nucleotide sequence of the chloroplast genome of the pteris amurensis is as shown in SEQ ID NO. 1; the GC content of the chloroplast genome of the pteris amurensis is 43.14%; the pteridium aquilinum chloroplast genome provided by the invention enriches a pteridium gene database, lays a foundation for exploring pteridium aquilinum evolution history and an adaptation mechanism of pteridium aquilinum to environmental stress, decrypts genetic codes of pteridium aquilinum from a molecular level, and is applied to biodiversity protection, plant ecological restoration and gardening.
